The 2012 Challenger comes in three available trims: the base, the R/T, and the SRT8. The R/T trim also offers a Classic upgrade option. For 2012, the base model has an updated 3.6 liter V6 engine, and the automatic transmission is five speeds. The R/T has a 5.7 liter V8 HEMI engine, and it adds sequential shift control to the automatic transmission. To the optional six speed manual transmission, the R/T adds 372 horsepower. The SRT8 model has a powerful 6.4 liter V8 hemi standard on the five speed auto transmission and sequential shift control. On the available six speed manual transmission, the SRT8 offers 470 horsepower with 470 pounds/foot of torque.
The base trim model comes standard with traction and stability control, touring suspension, keyless entry system, 17 inch alloy wheels, power driver's seat, and air conditioning. The R/T trim adds a performance tuned steering and suspension systems, heated exterior mirrors, body color spoiler, and 18 inch alloy wheels. The R/T Classic upgrades include 20 inch aluminum wheels, dual side stripes, HID headlamps, and a functional hood scoop.
The SRT8 trim upgrades the Challenger to a sport suspension system with two mode active dampening, limited slip differential, premium Brembo brakes, 20 inch alloy wheels, upgraded headlights, two hood stripes, Boston Acoustic sound system, and heated Nappa leather and suede seats. The SRT8 includes helpful features such as a universal garage door opener, compass, security alarm, and rear parking assistance. There are also optional equipment packages, including a navigation system, anti-spin rear differential, performance tires, sunroof, and multimedia entertainment system with a 30 gigabyte drive.
The 0 to 60 time is estimated in the upper four second range. Top speeds can reach 182 mph on the manual transmission and 176 with the automatic. Fuel economy ratings are 14 city, 22 highway, for the automatic, and 14 city, 23 highway, for the manual transmission.
A great improvement for the 2012 model year version is the two mode suspension. The Auto mode can adjust to both driver inputs and the road conditions, while the Sport mode locks into a higher dampening rate, perfect for high performance acceleration. Other impressive options include the heated steering wheel and the 18 speaker, 900 watt Harmon Kardon audio system. This audio system is equipped with GreenEdge, which tunes the speakers and amplifiers to use the least possible amount of energy. The 2012 retains the feel of the upgraded classic muscle car that customers appreciated in the 2011 model, making it an excellent choice for drivers who appreciate power and refinement.
