► 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. 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 -- an estimated 13-percent increase on the highway -- and an extended range of approximately 450 miles on one tank of gas. Standard steering wheel mounted paddle shifters join the standard AutoStick 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.
► 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.
► Chrysler 300 SRT8 (2012) on the track
The Street and Racing Technology (SRT) performance engineering team builds upon the all-new 2011 Chrysler 300 sedan already executed for a world-class luxury experience, to deliver Chrysler's most powerful and best handling model ever. Performance numbers include 0-60 mph acceleration in the high 4-second range; quarter mile in high 12-second range; 0-100-0 mph in less than 16 seconds, top speed of 175 mph and stopping power from 60-0 mph in 120 feet. The return of the 300 SRT8 to the Chrysler lineup in 2012 evokes a strong comparison to the original high-performance production car of its time -- the 1955 Chrysler 300. Known for simple, strong lines, excellent engineering, high levels of luxury and outstanding performance with the first modern American V-8 engine to produce 300 horsepower, the first Chrysler 300 (C-300) was styled by Virgil Exner, who radically redesigned the entire Chrysler line and created what they called "The Forward Look" in 1955. Without much chrome on the sides, his designs were simple, but strong. Exner is credited with creating the illusion of fast, forward movement. Under the hood of the 2012 Chrysler 300 SRT8, the new 6.4-liter HEMI® V-8 makes its debut in the Chrysler brand product lineup delivering 470 horsepower (351 kW) and 470 (637 N•m) lb.-ft. of torque, up 45 horsepower and 50 lb.-ft. over the 6.1-liter HEMI V-8 it replaces. The improved torque output -- including an additional 80 lb.-ft. at 2,900 rpm -- allows for inspired standing starts and improved straight-line performance while new, performance-tuned motor mounts improve idle stability and ride control at any speed. An active intake manifold and high-lift camshaft with cam phasing provides maximum low-end torque while optimizing high-end power.
