► 2012 Jeep Grand Cherokee SRT8

Designed and built using the proven SRT formula that raises the performance to astonishing levels, the new 2012 Jeep Grand Cherokee SRT8 runs from 0-60 mph in 4.8 seconds, 0-100-0 mph in the mid-16 second range, can cover the quarter mile in the mid-13 second range, has a top speed of 160 mph, and brakes from 60-0 mph in 116 feet. Powering the 2012 Jeep Grand Cherokee SRT8 is Chrysler Group's all-new 6.4-liter HEMI® V-8 with Fuel Saver Technology that delivers 470 horsepower (351 kW) and 465 (630 N•m) lb.-ft. of torque -- an improvement of 50 horsepower and 45 lb.-ft. torque over the 6.1-liter HEMI V-8 it replaces. An active intake manifold and high-lift camshaft with cam phasing delivers maximum low-end torque while optimizing high-end power across a wider and improved rpm band. Specifically, 90-percent of peak torque is available between 2,800 and 6,000 rpm, allowing for inspired standing starts and improved straight-line performance. Standard Fuel Saver Technology and a new-for-2012 active valve Exhaust system allows four-cylinder operation to engage over a wider rpm range, to deliver both improved fuel efficiency -- a 13-percent increase on the highway -- and an extended range of 450 miles on one tank of gas. Standard steering wheel mounted paddle shifters join the standard Auto Stick on the floor. Both are mated to a proven automatic transmission, allowing a choice of spirited shifting on the road and the race track. Both methods give the driver the ability to shift while the transmission controller calibration prevents situations that might over rev the engine. Fully adaptive electronic control of all shifting makes the powertrain more responsive while minimizing harshness. Chrysler Group's SRT vehicles are well known for their world-class braking. Stopping power for the 2012 Grand Cherokee SRT8 comes courtesy of new SRT high-performance Brembo brakes with four-wheel anti-lock brake system (ABS). Stopping distance performance of 116 feet from 60-0 mph is made possible by new red-painted, Brembo 6-piston (front) and 4-piston (rear) calipers, and vented rotors at all four corners measuring 15-inches (front) and 13.8-inches (rear). ► If you love cars, you should subscribe now to YouCar's channel: http://urlz.fr/lEd Go ahead, it's free!

► 2012 Jeep Grand Cherokee SRT8 reveals at NY
The most powerful, technologically advanced, high-performance Jeep® vehicle ever -- the all-new 2012 Jeep Grand Cherokee SRT8® -- arrives this summer with a combination of Jeep's legendary capability and utility, merged with the renowned advanced performance engineering from Chrysler Group LLC's Street and Racing Technology (SRT) team. Delivering outstanding driving performance in all conditions, and complemented by key SRT attributes -- including functional, performance-oriented styling, world-class ride and handling, benchmark braking and race-inspired interior appointments -- the 2012 Jeep Grand Cherokee SRT8 broadens the Jeep vehicle lineup and builds upon the successful launch of the award-winning 2011 Jeep Grand Cherokee.Designed and built using the proven SRT formula that raises the performance to astonishing levels, the new 2012 Jeep Grand Cherokee SRT8 runs from 0-60 mph in 4.8 seconds, 0-100-0 mph in the mid-16 second range, can cover the quarter mile in the mid-13 second range, has a top speed of 155 mph, and brakes from 60-0 mph in 116 feet.Powering the 2012 Jeep Grand Cherokee SRT8 is Chrysler Group's all-new 6.4-liter HEMI® V-8 with Fuel Saver Technology that delivers an estimated 465 horsepower and 465 lb.-ft. of torque -- an improvement of 45 horsepower and 45 lb.-ft. torque over the 6.1-liter HEMI V-8 it replaces.

► 2012 Grand Cherokee CRASH TEST
In the frontal impact, the driver's inboard seat rail was found to have very nearly broken in two, and was mainly held together only by the threaded steel rod which controls fore-aft adjustment of the seat. The break occurred just at the point where the lower anchorage for the driver's seat belt attaches to the rail, and is thought to have been caused by the high tensile forces in the belt during the test. As a result, there was additional forward movement of the dummy which contributed to 'bottoming out' of the airbag i.e. there was insufficient pressure in the airbag to prevent the driver's head from making contact, through the fabric of the airbag, with the steering wheel rim. Euro NCAP has been informed that Jeep are investigating the cause of the seat rail failure and intend to improve the seat track design, but have no current plans to re-work existing vehicles. Although dummy readings were good, structures in the dashboard were thought to present a risk of injury to the knees and femurs of occupants of different sizes and to those sat in different positions. Maximum points were scored in the side barrier test but, in the more severe side pole impact, protection of the chest was rated as marginal. The Grand Cherokee has an 'active' head restraint which senses when a rear-end impact has occurred and moves the restraint forward to minimise the time to restrain head movement. Jeep showed that the system responded in a broad range of accident severities, and the whiplash tests were performed with the system active. Nevertheless, the protection provided against neck injuries in a rear-end collision was rated as marginal.





2012 Jeep Grand Cherokee SRT8
The most powerful, technologically advanced, high-performance Jeep® vehicle ever -- the all-new 2012 Jeep® Grand Cherokee SRT8® -- arrives later this summer with a combination of Jeep's legendary capability and utility, merged with the renowned advanced performance engineering from Chrysler Group LLC's Street and Racing Technology (SRT) team. Delivering outstanding driving performance in all conditions, and complemented by key SRT attributes -- including functional, performance-oriented styling, world-class ride and handling, benchmark braking and race-inspired interior appointments -- the 2012 Jeep Grand Cherokee SRT8 broadens the Jeep vehicle lineup and builds upon the successful launch of the award-winning 2011 Jeep Grand Cherokee.

► 2012 Dodge Challenger SRT8 392 on the Track
http://www.youcar.tv The 392-cubic inch (6.4-liter) HEMI® V-8 delivers 470 horsepower (351 kW) and 470 (637 N•m) lb.-ft. of torque. The torque band is extremely flat allowing for strong standing starts and improved straight-line performance throughout the rpm range. An advanced active intake manifold along with high-lift cam with phasing provides maximum low-end torque and high-end power while still delivering up to 23 miles per gallon on the highway with the standard manual transmission. Performance-tuned engine mounts improve idle stability and ride control at all speeds. Standard Fuel Saver Technology (four cylinder mode) in automatic transmission equipped models allows the engine to operate economically on four cylinders or use the power of all eight cylinders when needed. The EPA fuel economy miles per gallon (mpg) (City/Hwy) ratings for the 2012 Dodge Challenger SRT8 392 are 14/22 for automatic transmission models and 14/23 for manual-transmission models. A look under the hood reveals unique valve covers with painted silver ribs and the "392 HEMI" logo, which gives the engine a unique, clean and aggressive look. The 2012 Dodge Challenger SRT8 392 features a standard Tremec TR-6060 six-speed manual transmission and a dual-disc high performance clutch -- a proven performer that was first offered on the 2008 Dodge Viper SRT10®. The optional five-speed automatic transmission features new, standard steering wheel mounted paddle shifters that join the center console mounted Auto Stick, allowing for a choice of spirited shifting on both the road and the race track. Both methods give the driver the ability to manually select specific gears on the transmission. In "Drive," the transmission controller will automatically shift the vehicle. The aggressiveness of the shifting is defined by the mode chosen - either "Normal" or "Sport." Fully adaptive electronic control of all shifting makes the powertrain more responsive while minimizing harshness. In "Manual," the shift method is defined by the driver choosing to use either paddle shift or Auto Stick. The "Sport" mode adds a hold function to the calibration in all gears, allowing the driver full control of the shifting schedule.
