The 2012 Chrysler 300 SRT8 comes with a new 6.4-liter HEMI® V-8 delivering an estimated 465 hp and 456 lb.-ft of torque.
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.
Even with the elevated power numbers, an estimated 25-percent fuel economy increase on the highway is achieved by use of a new for 2012 active valve exhaust system that allows the standard Fuel Saver technology (four-cylinder mode) to engage over a wider rpm range. The new active exhaust system on Chrysler 300 SRT8 also allows for straight-through mid and rear mufflers for a throaty exhaust note under engine load.
The 2012 Chrysler 300 SRT8 equipped with standard steering wheel-mounted paddle shifters join the standard Auto Stick on the floor console. Both are mated to the proven five-speed automatic transmission, allowing a choice of spirited shifting on the road and the race track.
New for 2012 is an Adaptive Damping Suspension (ADS) system that is tuned specifically for the Chrysler 300 SRT8 to offer a compliant and comfortable ride. The ADS system also uses a wide range of on-road and driver inputs – such as vehicle speed, steering angle, steering speed, brake torque, throttle position and lateral and vertical accelerations – to automatically tune the suspension for specific conditions when necessary.
SRT vehicles are well known for their world-class stopping power and the 2012 Chrysler 300 SRT8 features 14.2 inch (front) and 13.8 inch (rear) vented/slotted rotors with four-piston Brembo calipers painted in silver finish. Improved brake cooling and fade performance comes courtesy of new underbody belly pan with integrated brake ducting.
The 2012 Chrysler 300 SRT8 is one-half inch lower when compared to the base car and features new SRT-exclusive side sill cladding painted in matching body color for the “planted” look of a true sports sedan.
