V10 Drag Pack
Updated to include 2011+ cars thanks to oh2o
The Challenger SRT8 used a 6.1 liter Hemi from 2008-2010, and a 6.4 liter 392 Hemi from 2011 on. The Challenger R/T always used a 5.7 liter Hemi; the Challenger SE, a V6 (3.5 liters until 2010, and 3.6 liters from 2011 onwards.) Also see: Hemi engines • Pentastar V6 engines • 3.5 liter “LH” V6 engines
The 392 Hemi takes 5W-40 synthetic oil, an unusual requirement. It has pushrod-activated overhead valves (sodium filled exhaust, hollow-stem intake), with 16 conventional hydraulic lifters using roller tips. Fuel injection is returnless; the automatic cuts the fuel supply when coasting when certain conditions are met. The block is a deep-skirt, cast iron design with cross-bolted main bearing caps and aluminum alloy heads. Oil capacity is 7 quarts, coolant is 14 quarts; bore and stroke is 4.09 x 3.72 inches.

Is the Challenger really too heavy, as some say?
Thanks to cd36. * R/T model weighs 4,041 pounds.
The five speed automatic was used on all engines starting in 2011. The four speed automatic was used only with the V6 in 2009. The six speed manual was used on R/T and SRT8 models, and was a Tremec TR-6060 with ZF-Sachs 240mm twin-disc clutch. It had a triple cone synchronizer design in first and second gears, with double cones in higher gears; it used 1-4 skip shift and reverse inhibit solenoids. Gear ratios did not change from 2010 to 2011.
Front suspension is independent short-long arm with high upper A arm, coil springs over gas charged monotube shock absorbers and solid stabilizer bar with lateral and diagonal lower links with dual ball joint knuckles.
Rear suspension is a five link independent design with coil springs, gas charged monotube shocks, solid stabilizer bar, and isolated suspension cradle.
Starting in 2011, electro-hydraulic power steering was used on SE and R/T models (SRT8 remained hydraulic.) SRT8 used Bilstein shocks, front and rear.
Other specs. For the sake of convenience, the 2008-2010 Challengers are referred to in this chart as G1, while 2011 and newer are referred to as G2.

The 2012 (probably 2011-14) Performance Brake Package, according to “oingoboingo,” was standard on any Charger with the 5.7 Hemi, and included with the Rallye Appearance Group and Blacktop Package on SXT and SXT Plus (RWD) cars. The vented front rotors were 13.6 x 1.26 with dual-piston sliding calipers (aluminum housings). In back, they used 12.6 x 0.87 inch vented rotors in a single-piston sliding caliper with an aluminum housing.
Specs that changed in 2011:
Frontal area and drag coefficient are a bit complex:
* 17 inch wheels were not used in 2011 or beyond
Specifications that did not change by model or by year:
Thus, the dealer actually pays considerably less than the $40,027 “wholesale price” for the 2008 Dodge Challenger SRT8 car. Dealers usually pay less than the wholesale price minus the holdback (in this case, $40,027 - $1,239 = $38,788), with an advertising reimbursement and supplemental floorplan reimbursement. That profit is reduced or eliminated by financing charges on stored cars, insurance, commissions and salaries, advertising, etc.
