Nissan unveils 2010 370Z Roadster and NISMO 370Z

Less than a year after the introduction of the all-new 2009 Nissan 370Z Coupe – a vehicle that reset the bar for affordable sports car design and performance – comes its dramatic new stablemate, the 2010 Nissan 370Z Roadster. The seductively styled Z® Roadster offers everything the hardtop Z® Coupe does – and more. As in more classic open-air sports car driving excitement. More sun, moon and stars. And more refinement than any Z® convertible that has ever come before – including a standard automatic latching power top and Nissan Intelligent Key™. Also offered are an array of technology and convenience features, including the first-ever Z® Roadster-available heating and cooling ventilated net seats, Bluetooth® Hands-free Phone System, satellite radio and advanced Nissan Navigation System. The 2010 370Z Roadster is scheduled to go on sale at Nissan retailers nationwide in late summer.

"As expected, the 370Z Roadster delivers an exhilarating connection to the air, wind and environment on top of the new Z® Coupe's exceptional levels of performance," said Al Castignetti, vice president and general manager, Nissan Division, Nissan North America, Inc. (NNA). "But perhaps unexpected for a car this sporty is its greatly enhanced refinement and quality – as seen in features such as its one-touch, auto-locking convertible top and beautifully crafted interior."

A Truly Authentic Roadster

The 370Z Roadster's most obvious departure from the 370Z Coupe is its convertible top. The soft-top roof was designed with an emphasis on three key areas: to provide a sleek silhouette matching the new Z®'s stunning styling with the top up or down, to offer easy single-action open-close operation, and to provide an enjoyable top-down experience with reduced wind turbulence and all-climate driver/passenger comfort.

With convertible top in the closed position, the design provides a sophisticated sloped-back appearance, the perfect balance between the soft top and the Z® body design. The shortened windshield and aerodynamically rounded rear deck enhance the Z®'s kinetic and dynamic character lines. When in the down position, the convertible top is concealed beneath a full body-color hard tonneau cover, which extends forward to help create the Z® Roadster's classic "double cockpit" style interior.
 
The standard black cloth convertible top features a fabric inner liner, which provides a quality appearance and helps reduce noise intrusion into the cabin, along with an enlarged (versus the previous generation Z® Roadster) glass rear window with an integrated electric rear window defroster. The top operation takes approximately 20 seconds start-to-finish and is controlled by either a center console-mounted switch or by a button located on the doors. The automatic latch system secures the top to – or releases it from – the windshield header without driver intervention. The shape and position of the glass wind deflector, located between the fixed headrest bars, has been optimized to reduce turbulence into the cabin.

Like the new 370Z Coupe, the Z® Roadster's new exterior is more aggressive in appearance and lighter and tighter in structure than the previous generation. The wheelbase is nearly four inches shorter (100.4 inches versus 104.3 inches) and overall length is reduced by 2.6 inches (167.2 inches versus 169.8 inches). The new Z® Roadster features an aluminum hood, door panels and trunk for reduced weight. At the same time, the body structure was extensively revised, improving rigidity and stability. The 370Z Roadster includes additional structural reinforcement (over the 370Z Coupe), including in the A-pillars and side sills.

The Z® Roadster's exterior design incorporates the look and feel of the new Z® Coupe, including its signature long nose/short cockpit proportions, vertical door handles and distinctive new headlight/taillight treatment, which features a fierce "boomerang" shape. High Intensity Discharge (HID) bi-functional xenon headlights with auto on/off feature are standard.

The 370Z Roadster is offered in seven exterior colors: Solid Red, Magnetic Black, Brilliant Silver, Platinum Graphite, Pearl White, Monterey Blue and a special premium color, Black Cherry.

Inside the stunning exterior, true to its sports car heritage, the Z® Roadster's interior is completely driver-centric, with its three-layer design grouping items by how a driver sees information, operates the controls and is held in place – so drivers feel completely connected and engaged whenever and wherever they drive, top up or down.

The Z® Roadster features high back black woven "Carbon" cloth seats with 8-way manual driver's/4-way manual passenger's seat adjustments. Touring models include unique leather-appointed "net" seats with 4-way power/4-way manual operation on the driver's seat (4-way power on the passenger's seat). These second-generation net seats are exclusive to the Z® Roadster and have integrated heating and cooling functions – ideal for open air driving no matter what the outside temperature. Adjustable front seat Active Head Restraints are also standard.

The Z® Roadster's 2-seat layout includes a deeply scooped instrument panel with a full-length center console separating the driver and passenger's seat. The instrument panel retains the traditional Z® 3-pod cluster with oil temperature, voltmeter and clock, while the speedometer and tachometer now include an "initial sweep" function, coming alive when the car is first started.

The sporty steering wheel is a new "oval" 3-spoke design, which offers baseball-style stitching, improved thumb grips and palm rest areas for improved feel on long drives. The surface of the leather-wrapped wheel is "shaved" to provide a more kidney-like shape to better fit in the hand. The manual transmission shifter is specially padded to improve the accuracy of diagonal shifts and to feel softer in the hand for forward and backward motions.

Standard interior comfort and convenience features include Nissan Intelligent Key™ with Push Button Ignition, power windows with one-touch auto up/down feature, power door locks with auto-lock feature and a center console box with a non-intrusive cover design.

Other features include automatic climate control, two 12-volt power outlets, three cupholders (two in door panels, one in center console) and an AM/FM/CD/AUX 4speaker audio system with illuminated steering wheel-mounted controls.

The Touring model adds a 6CD Bose® audio system with eight speakers (includes dual subwoofer) and MP3/WMA playback, XM® Satellite Radio (XM® subscription required, sold separately), Bluetooth® Hands-free Phone System, HomeLink® Universal Transceiver and aluminum-trimmed pedals. This is the first time Bluetooth® and satellite radio have been available on a Z® convertible.

The optional Navigation Package includes the touch-screen Nissan Hard Drive Navigation System with XM NavTraffic® real-time traffic information (XM® subscription required, sold separately), 9.3GB Music Box hard drive for digital music storage and playback and a USB fort for iPod® connectivity. The new navigation system offers a number of enhancements (versus previous Nissan Navigation System designs), including four times higher screen resolution, wireless music player audio streaming capability (via Bluetooth®), on-board Zagat restaurant ratings database, an in-dash DVD player and XM NavWeather® weather information display (XM® subscription required, sold separately).

The 370Z Roadster interior is available in Black cloth or for 370Z Touring Roadster models, a choice of Gray, Black or Wine leather-appointed net seating.

Open Air, Open Roads – An Unbeatable Combination

Roadster or Coupe, the new Z®s share one of the most advanced drivetrains available for affordable sports cars today. The Z® Roadster's long list of cutting edge performance-focused technologies includes a standard 332-horsepower 3.7-liter DOHC V6 engine with Variable Valve Event and Lift Control (VVEL), choice of 7-speed automatic transmission or close-ratio 6-speed manual with available "SynchroRev Match" (the world's first synchronized downshift rev matching manual transmission), refined 4-wheel independent suspension and 4-wheel vented disc brakes (with available Nissan Sport Brakes).

"The new 370Z Roadster lives in the same sweet spot of performance, style and value that the Z® Coupe does," said Castignetti. "Open air driving just begs for open roads and the new 370Z Convertible is the perfect companion."
Compared to the previous generation 350Z Roadster, the new Z® convertible picks up 26 horsepower and 2 lb-ft of torque (332 horsepower @ 7,000 rpm and 270 lb-ft of torque @ 5,200 rpm, compared with the previous 3.5-liter V6's 306 horsepower @ 6,800 rpm and 268 lb-ft of toque @ 4,800 rpm).

Along with its larger displacement, the 3.7-liter engine gives better power delivery all the way to the 7,500 rpm redline, improved low-end power and more high-end torque, creating an entirely new driving experience. Key to the enhanced performance is the VVEL system, which is able to optimize intake valve open/close movements, allowing the needed air to be sent promptly to the combustion chamber at the precisely optimized time. Since the VVEL system can adjust to open the valves slightly, it improves fuel efficiency by reducing camshaft friction and fuel waste. It also provides cleaner emissions by allowing for quicker warm-up of the catalyst and by stabilizing combustion when the engine is cool.

The 2010 Z® Roadster is offered with a choice of two new advanced transmissions – a close-ratio 6-speed manual or 7-speed automatic. The 6-speed manual is available with SynchroRev Match™ (included in the optional Sport Package), which allows drivers of any skill level to experience professional-like gear shift performance. The SynchroRev Match™ function automatically controls and adjusts engine speed when shifting to the exact speed of the next gear position, essentially "blipping" the throttle to smooth out any up/down shifts. This not only allows the driver to focus more on braking and steering, it improves vehicle balance and smoothness by reducing the typical "shock" when the clutch is engaged. The system can be deactivated with a button next to the shifter for drivers who prefer less vehicle intervention.

The available 7-speed automatic includes Downshift Rev Matching (DRM) and Adaptive Shift Control (ASC) and is designed to offer quick, manual-like shifting when operated in manual mode.

Drivers can use the standard paddle shifters or the shift lever. The 7-speed's wide gear ratios offer improved fuel efficiency, while the Adaptive Shift Control is designed to adjust to the driver's driving style.

Estimated fuel economy for the 370Z Roadster is 18 mpg City/25 mpg Highway for both the 7-speed automatic and 6-speed manual transmissions – increases of 1 mpg City/2 mpg Highway for the automatic and 1 mpg City/1 mpg Highway for the manual transmission versus the 2009 350Z Roadster.

The Z® Roadster also utilizes the Z® Coupe's advanced 4-wheel independent suspension. The double-wishbone front suspension (which replaces the lower multi-link setup in the 350Z) uses lighter forged aluminum arms and a lightweight rigid aluminum-alloy cradle, along with a lighter stabilizer bar with a 35 percent improved lever ratio. The 4-link rear suspension is also stiffer and lighter, with the rear cradle entirely integrated into a single part. "High response" shock absorbers are utilized on each corner for improved ride comfort.

The standard 370Z Roadster wheel and tire package features 18x8.0-inch front/18x9.0-inch lightweight aluminum-alloy wheels with P225/50R18 front/P245/45R18 rear Bridgestone Potenza RE050A summer tires. Available as part of the optional Sport Package are 19-inch RAYS forged lightweight aluminum-alloy wheels with Bridgestone Potenza RE050A P245/40R19 front/P275/35R19 tires.

The Z®'s standard 4-wheel vented disc brake system includes Anti-Lock Braking System (ABS) with Electronic Brake force Distribution (EBD) and Brake Assist (BA). The optional Sport Package includes Nissan Sport Brakes with large diameter 14.0-inch front and 13.8-inch rear rotors (versus 12.6-inch front/rear standard rotors) with 4-piston front and 2-piston rear aluminum calipers.

Steering is provided by a vehicle-speed-sensitive power-assisted rack-and-pinion design. Unwanted steering kickback and vibrations are reduced with the addition of a solenoid valve that acts like a damper when there is a harsh impact load. A Vehicle Dynamic Control (VDC) system is standard.

The Nissan 370Z Roadster's list of standard safety features includes the Nissan Advanced Air Bag System (AABS) with dual-stage supplemental front air bags with seat belt and occupant classification sensors; front seat-mounted side impact supplemental air bags; door-mounted curtain air bags; and seat belts with pretensioners and load limiters.
Other standard equipment includes Active Head Restraints, Zone Body Construction with front and rear crumple zones, Nissan Vehicle Immobilizer System, Vehicle Security System and Tire Pressure Monitoring System (TPMS).

Two Well-Equipped Models

The new Z® Roaster is offered in two well-equipped models – 370Z Roadster and the 370Z Touring Roadster. The Touring model includes the heated and cooling leather-appointed power net seats, HomeLink® Universal Transceiver, Bluetooth® Hands-free Phone System, 8-speaker Bose® audio system, XM® Satellite Radio (XM® subscription, sold separately) and aluminum-trimmed pedals.

Only two option packages are offered (Touring model only): the Sport Package, with 19-inch RAYS forged wheels and Bridgestone Potenza tires, Nissan Sport Brakes, SynchroRev Match (6-speed manual transmission only) and Viscous Limited Slip Differential; and the Navigation Package, with Hard Drive-based Nissan Navigation System, 9.3GB Music Box Hard Drive and USB connectivity.

The all-new, second generation NISMO 370Z, which is set to go on sale at Nissan retailers nationwide in June 2009, continues the tradition of the original by offering unique performance and design attributes that true sports car enthusiasts are looking for – straight from the factory. Like the limited production NISMO 350Z introduced two years earlier, the new NISMO 370Z is a tuner-Z® enthusiast's dream, featuring a 350-horsepower 3.7-liter V6, racing-inspired exterior and interior styling, a specially tuned suspension and special super-lightweight 19-inch forged alloy wheels.

The 2009 NISMO 370Z was developed by NNA's Specialty Vehicles Group in conjunction with Autech Japan, Nissan's longstanding conversion partner.

"The NISMO name is known throughout the world as the leading supplier of race-bred, factory-tuned, extreme performance Nissan parts, accessories and vehicles," said Al Castignetti, vice president and general manager, Nissan Division, Nissan North America, Inc. (NNA). "The new, second-generation NISMO Z® proudly – and deservedly – wears the NISMO badge, carrying on the tradition of bringing racing-inspired performance and engineering to the street."

The all-new NISMO 370Z is offered in one completely equipped model (no options) with a close-ratio 6-speed manual transmission only.

Dynamic Performance And Handling Comes Standard

The new NISMO 370Z starts with the unmatched foundation of an advanced Nissan FM (Front Midship) platform, refined 4-wheel independent suspension and 3.7-liter DOHC V6 engine with Variable Valve Event and Lift Control (VVEL). The VVEL system helps optimize intake valve open/close movements, allowing the needed air to be sent promptly to the combustion chamber at the precisely optimized time. For its use in the NISMO 370Z, the 3.7-liter VQ-series V6 produces 350 hp @ 7,400 rpm and 276 lb-ft of torque @ 5,200 rpm. The NISMO Z®'s enhanced engine power and acceleration is provided through use of an exclusive H-configured exhaust system design and muffler tuning, along with optimized ECM (Engine Computer Module) control.

The NISMO 370Z is offered only with a close-ratio 6-speed manual transmission with Nissan's new "SynchroRev Match" function, the world's first synchronized downshift rev matching manual transmission system. The "SynchroRev Match" function automatically controls and adjusts engine speed when shifting to the speed of the next gear position, essentially "blipping" the throttle to smooth out any up/down shifts. This not only allows the driver to focus more on braking and steering, it improves vehicle balance and smoothness by reducing the typical "shock" when the clutch is engaged. The system can be deactivated with a button next to the shifter for drivers who prefer less vehicle intervention.

The NISMO 370Z features a tight, rigid body structure with a strut tower bar brace and a pair of performance dampers, which quickly and efficiently react to and control body vibrations from road input via the tires, contributing to the NISMO 370Z's outstanding stability and performance feel.

The NISMO Z®'s double-wishbone front/4-link rear suspension design suspension is specially tuned for exceptional stability and handling. Compared to a standard Nissan 370Z Coupe, front spring rates have been dialed up 15%, rear spring rates 10%, front stabilizer bar rate upped 15% and the rear stabilizer bar is 50% stiffer. The roll stiffness rate has been increased by 15% and front and rear damping factors have been increased by 40% and 140% respectively.

The NISMO 370Z rides on unique 5-spoke Nissan-branded 19-inch RAYS forged aluminum-alloy wheels (19x9.5-inch front, 19x10.5-inch rear) mounted with Yokohama ADVAN Sport Y-rated high-performance tires (P245/40ZR19 front, P285/35ZR19 rear).

Bringing the NISMO 370Z to a stop are standard NISMO Sport Brakes with large diameter 14.0-inch front and 13.8-inch rear vented rotors with 4-piston front and 2piston rear aluminum calipers. The braking system also includes a variable ratio brake pedal for a more direct pedal stroke feel, Anti-Lock Braking System (ABS), Electronic Brake force Distribution (EBD) and Brake Assist (BA). A Viscous Limited-Slip Differential (VLSD) is standard on all NISMO 370Zs, along with Vehicle Dynamic Control (VDC).

Responsive steering is provided by a vehicle-speed-sensitive power-assisted rack-and-pinion design that has been reworked (versus the NISMO 350Z design) with redesigned mounting bushings and a column insulator to provide improved response. Unwanted steering kickback and vibrations are reduced with the use of a solenoid valve that acts like a damper when there is a harsh impact load.

Unique NISMO 370Z Exterior and Interior

Along with its standout performance, the new NISMO Z® offers a standout appearance inside and out. The functional and fully integrated aerodynamic body pieces include an extended front nose design with a canard design at each corner for improved downforce and a fully integrated chin spoiler. The NISMO 370Z has an overall length of 174.3 inches.

Special side sills and a unique rear bumper help control airflow under the vehicle, while the functional rear spoiler increases downforce. The NISMO 370Z exterior also includes a wide stance, sculptural fenders, upswept quarter windows, bold "boomerang" shaped headlights and taillights, vertical door handles and aluminum hood, door panels and hatchback. The headlights are a High Intensity Discharge (HID) bi-functional xenon design with an auto on/off feature.

"One look at the dramatic NISMO 370Z body and you know that this isn't your everyday sports car," said Castignetti. "The styling is highly emotional yet totally functional – expressing dynamic movement while enhancing airflow and downforce for enhanced aerodynamic performance."

The NISMO 370Z is offered in five exterior colors: Pearl White, Brilliant Silver, Magnetic Black, Solid Red and Platinum Graphite.

The NISMO 370Z's driver-centric interior includes NISMO logo seats with black and red fabric and red stitching, a NISMO tachometer, steering wheel with smooth leather and red parallel stitching, smooth leather-wrapped shift knob and aluminum trimmed pedals. A special serialized plaque of authenticity, located on the vertical panel above the floor-mounted console, is matched to each NISMO Z®, identifying its unique serial and model year designation.

The NISMO 370Z's 2-seat interior layout is built around a deeply scooped instrument panel with a full-length center console separating the driver and passenger's seat. In the rear is an open cargo area with enhanced storage and accessibility. The instrument panel includes a 3-pod cluster with oil temperature, voltmeter and clock, while the speedometer and tachometer include an "initial sweep" function, coming alive when the NISMO Z® is first started.

Both the driver and passenger's seats are structured with an anti-slip material in the main seating surface. The sporty woven cloth seats feature standard 8-way driver's/4-way passenger manual adjustments. Adjustable front seat Active Head Restraints are standard.

Standard interior comfort and convenience features include Nissan Intelligent Key™ with Push Button Start, power windows with one-touch auto up/down feature, power door locks with auto-lock feature, a center console box with a new non-intrusive cover design, automatic climate control, rear window defroster with timer, two 12volt power outlets, four cupholders (two in door panels, two in center console), dual overhead map lights and a AM/FM/CD/AUX 4-speaker audio system with illuminated steering wheel-mounted controls.

"The NISMO logo is prominent throughout the cabin, reinforcing the mission and special capability of the vehicle," said Castignetti. "The NISMO Z® is the complete package – inside, outside and under the skin."
The NISMO Z's long list of standard safety and security features includes the Nissan Advanced Air Bag System (AABS) with dual-stage supplemental front air bags with seat belt and occupant classification sensors; front seat-mounted side impact supplemental air bags; roof-mounted side-impact air bags; seat belts with pretensioners and load limiters, Active Head Restraints, Zone Body Construction with front and rear crumple zones, Nissan Vehicle Immobilizer System, Vehicle Security System and Tire Pressure Monitoring System (TPMS).

the NISMO 370Z is one HELLUVA competitor for the Audi TT-RS. i'd like to see how it holds up to the TT-RS' Quattro AWD.

Land Rover unveils more powerful and facelifted Range Rover, Range Rover Sport, Sport Supercharged, and facelifted/renamed LR4

Like the new LR4 and classic Range Rover, the Range Rover Sport also gets plenty of upgrades for the 2010 model year. Like the regular RR, the Sport gets the same 5.0L direct-inject V8s from Jaguar in either naturally aspirated or supercharged guise plus a new six-speed automatic transmission. The NA puts out 375 hp and 375 lb-ft of torque while the force fed mill creates 510 hp and 461 lb-ft of torque, the latter good for 5.9-second sprints to 60 mph. The Sport's exterior has also been tweaked with a new two-bar grille centered in the revised front end and new rear tail-lamps nestled above a redesigned rear bumper. The interior has also been redone with higher quality materials and a new steering wheel that includes paddle shifters on the supercharged model. Throw in enough electronic nannies to make even the Queen look like a good driver and you've got an eminently more capable sports SUV than the one it replaces.

While Land Rover's sales have been flagging like almost every other automaker in this economy, it has been the company's venerable Range Rover SUV that has held down the fort, maintaining its share better than any other product in the British automaker's empire. This is a particularly impressive feat, as the Range Rover is the longest-serving model in the company's off-road arsenal to go without a major update. Until now.

Not that you can tell from the outside terribly easily, mind. The outgoing model is something of a style icon, so you could forgive LR stylists for not wanting to futz unnecessarily with the styling. Still, changes are substantial yet modest – there are new headlamps, a new grille, a refreshed bumper cap, relocated fog lamps, and a triple theme to the sides and rear of the vehicle that includes three-section fender vents, 'three-stripe' LED side indicators, and new LED taillamps that incorporate the same 'three-stripe' motif.

Inside, the changes are more dramatic, punctuated by a new virtual gauge cluster that utilizes a 12-inch Thin Film Transistor (TFT) screen in place of traditional analog needle instruments – Current Mercedes S-Class owners enjoy a similar setup. Other interior adjustments include a raft of new switchgear, a revamped steering wheel with new multi-directional thumbpads, a new leather headliner and a much-needed upgrade to the navigation system. The new GPS system is hard-drive based touchscreen setup that also includes enhanced USB connectivity and a dedicated iPod port.

wow, Land Rover is really stepping upto the performance SUV game. now their almost upto par with the new BMW X5M, Porsche Cayenne Turbo S, and Mercedes-Benz ML63 AMG.

[Elmo187]

On the eve of the New York Auto Show, Land Rover has released all the details on its new 2010 LR4. The new LR4 (the SUV formerly-known-as LR3) is packing a thoroughly revised, direct-injected 5.0-liter V8 sourced from Jaguar putting 375 hp and 375 lb-ft of torque through a six-speed automatic transmission. Land Rover has updated its Terrain Response system to deliver five different settings to suit the terrain, ranging from a normal driving mode to the infamous "Rock Crawl" setting.

A new front end with revised headlamps and fascia joins a restyled rump with LEDs, while an all-new interior provides ample accommodations for five or seven passengers, depending on spec. A Surround Camera system joins keyless entry, push-button start, gradient release control and tow assist (max. towing is 7,716 pounds) to make jaunts to Grandma's through the snowy climes a breeze. A revised suspension architecture, improved steering and larger brakes (14.2-inch discs in front and 13.8-inch rotors in the rear) round out the major modifications.

Jeep unveils all-new 2011 Grand Cherokee

Jeep's solution to its two-audience conundrum is the model you see before you, and while it shares lots of familiar cues, in the metal it looks at once far more aggressive than the exiting lantern-eyed WK, and ultimately more crossover-like. While it retains iconography like the seven-slot grille, the new headlamps have a meaner look thanks to a furrowed-brow appearance granted by the new hood. Perhaps the most dramatic departure is the profile view, where a new CUV-like tapering greenhouse takes up residence above a dramatically scalloped bodyside graphic. According to Gilles, the door panel indent is so pronounced that the company says they were "one step away from needing a compound hinge" to pull it off. If that profile looks longer to you, that's because it is – the wheelbase has swelled by four-inches, with that extra space dedicated completely to rear-seat passengers (+ three inches) and cargo room (+ one inch). The rear end is all-new as well, with a cleaner license plate surround and more horizontally oriented tail-lamps that emphasize the Grand Cherokee's wider width. Loyalists take note: Your pass-through rear glass has been retained.

So, this new model has a longer wheelbase and a more refined, crossover-like aesthetic. How exactly is that going to appeal to the mudpluggers in the audience? Well, Jeep has added a bounty of new off-road minded technology, in addition to new powertrains and a stiffened structure.

Starting with the engine choices, the volume model is expected to be the company's new flex-fuel "Phoenix" V6. The variable-valve timing equipped 3.6-liter engine nets 280 horsepower and 260 pound-feet of torque at 4,800 rpm – a substantial 33% bump in horsepower and an 11% boost in torque over the departing V6. Backed by a carryover five-speed automatic, it is also a more efficient powertrain, with a claimed 11% increase in fuel economy. This new six-cylinder is scheduled to appear in many more products, potentially showing up in seven or eight different applications. Jeep officials expect the V6 to account for more than 50 percent of Grand Cherokee sales, a big switch over the WK GC, which skews more than 75 percent in favor of the V8.

Speaking of which, the 5.7-liter HEMI V8 has also been worked on, and it now generates 360 hp and 390 lb/ft of torque. Sizable efficiency gains are also expected, as the variable-valve timed engine will also use the company's cylinder deactivation technology (Multi-Displacement System) more often than in previous incarnations, and the gearbox picks up a sixth cog, as well. Regardless of which engine is selected, total range ought to improve, with Jeep quoting over 500 miles for the V6 thanks to the 24.6-gallon fuel tank (four gallons larger than before).

All of that power is nothing without added control, and to that end, Jeep has taken pains to greatly improve torsional stiffness in the chassis, something that both everyday commuters and off-roaders will appreciate. The new structure (based heavily on the Mercedes-Benz ML) has upwards of 5,400 welds, including 53% more spot welds and 42% more arc welds. There's also a further 38% increase in structural adhesive use. The net-net is a chassis that's 146% stiffer – one that Jeep says bests the Toyota Highlander and BMW X5 for rigidity and allows for a maximum tow rating of 7,400 pounds.

So... what about that off-road hardware we talked about? During our private walkaround at Chrysler's Auburn Hills headquarters, Scott Kunselman, vice president of Chrysler's Jeep and truck product team was clearly excited to tell us about all of the new off-road gubbins that the company has managed to pack into this new model.

While lower-end models make do with a standard steel springs, there is an all-new Quadra Lift air suspension option that allows the driver to dial up ground clearance of up to 11.1 inches to crawl over boulders and downed tree branches. It's exactly the sort of equipment that helps increase the GC's breakover angle despite having a longer wheelbase (a full complement of skid plates is optional). That air suspension can also be lowered to parking height for easier ingress and egress, and if it's anything like Land Rover's air suspension setup, it figures to offer a more accommodating ride in the bargain.

Another bit of tech that reminds us of those boys from Solihull is Jeep's new Selec-Terrain system, a rotary controller that comes with models spec'd out with the top-shelf Quadra-Drive II 4x4 system. Selec-Terrain enables users to gird the vehicle's various systems (electronic limited-slip differential, traction control, stability control, two-speed hill-descent control, anti-lock, and so on) for various ground conditions, including Sand/Mud, Snow and Rocks. There is also a default automatic setting, and unlike the blokes at Land Rover, there is also a Sport mode that lowers ride height and allows for a bit more hooliganism before the electronic nannies kick in.

Predictably, there are more available creature comforts than ever before, including a much-improved interior with additional space, richer materials, tighter panel gaps, and more available toys. Some of the optional niceties include a mammoth twin-panel panoramic roof, an intelligent remote start (which automatically heats or cools the interior based on outside air temp), a collision warning system, adaptive cruise control, and a blind-spot/rear cross path detection system.

On the surface, at least, it looks like Jeep has managed an unlikely feat at the most crucial of junctures – it has seemingly imbued the Grand Cherokee with the credentials necessary to simultaneously court a wider roadgoing audience while giving it the goods to finish the job off road. That Chrysler has given this vehicle a 2011 model year designation while others are still introducing their 2010 lineup is not an error – the embattled automaker needs all the hits it can get right now as it seeks further government relief and help from Fiat. Wheeling out the GC well in advance of its debut in showrooms should only help the company build its case for eventual viability... and that thankless task will clearly be the 2011 Grand Cherokee's biggest obstacle to overcome.

it sounds like Chrysler wants this new GC to save Jeep from going off on their own. there's been word that International is interested in buying Jeep.
