2008-2010 Dodge Challenger cars: first of the new generation
Powering the Dodge Challenger R/T was the popular 5.7-liter Hemi V-8 engine. It pushed out 370 horsepower with a five-speed automatic; buyers of the six-speed manual transmission got 375 hp, but had to put in premium gas.
The Hemi V8 belted out 398 lb-ft (540 Nm) of torque (404 lb-ft / 548 Nm with manual), and the Challenger R/T could do 0-60 in under six seconds, quite good for the time and not far from the 2015 models.
Gas mileage on the Dodge Challenger Hemi was on the good side for a car of its size and power, with the 5.7 liter Hemi getting 16 mpg city, 23 highway (automatic; the manual transmission drops down to 15 city, 23 highway, and requires premium, rather than midgrade, gas). On the highway, without dropping speed, we maintained 27 mpg with the stick.
The Challenger SE, with 3.5-liter V-6, was rated at 18/25, somewhat less satisfactory; the 3.5 was slower than the same engine in the old Dodge Intrepid R/T.
For 2009, the Hemi engine was upgraded to get higher gas mileage and more power, especially at lower engine speeds, via an expanded cylinder cutoff range, increased compression ratio, better port flow, and reduced restriction intake and exhaust. Other updates were crankshaft structural upgrades, a dual-mass crankshaft damper, floating pin piston design, valve spring design, and oil pump capacity increase.
The 3.5 liter V6 uses a dual-tuned intake manifold with electronically controlled manifold short-runner valves (SRV) — in other words, switching from short to long runners to achieve a “supercharging” effect at various engine speeds.
|SRT-8||425 @ 6200||420 @ 4800|
|R/T manual||375 @ 5,800||404 @ 4,200||15/24|
|R/T auto||370 @5,800||398 @4,200||16/23|
|Challenger SE||250 @ 6,400||250 @ 3,800||17-18/25|
The six-speed Tremec TR-6060 manual transmission was derived from the one in the Dodge Viper SRT10, with triple cone synchronizers in first and second gears and dual cone synchronizers for third through sixth gears, along with new gear ratios. The clutch was the Viper’s (ZF-Sachs) 250 mm twin-disc design, with a 1-4 skip-shift and reverse inhibit solenoids, and a 5:1 remote shifter.
Hill Start Assist (HSA) was standard with the manual transmission; it held the brake for three seconds to let the driver start up hills more easily, releasing when the system sensed torque. The manual transmission had a unique dual exhaust with low-restriction bottle resonators replacing the underfloor muffler, and bright pedals.
The manual-transmission Challenger R/T also had a variable displacement power steering pump, different rear shocks, and other tuning changes — and the ability to shut off the ESP completely. Gas mileage was lower than the automatic, due to the lack of cylinder shutoff. A special-edition Dodge Challenger Classic R/T was be available late in the 2009 model year, with B5 blue paint, black side stripes, unique badging, and 20-inch five-spoke aluminum wheels.
The five-speed automatic (V8) had an aggressive first-gear ratio for launch performance, and AutoStick to select a higher or lower gear. V6 cars carried forward the old four-speed.
Gear ratios for each transmission are listed under “specifications.”
Some early manual transmission cars fouled the plugs on cylinder #7 (ECM code P0307). The issue appeared to be sensor calibration, and was fixed with a computer update.
Brakes and suspension
The Dodge Challenger R/T with a manual transmission had a variable displacement power steering pump to cut fluid temperatures and parasitic losses (raising fuel economy by 0.2 mpg); all Challengers had speed-sensitive power steering.
The front suspension was an independent short-long arm design with a high upper A arm, coil spring over gas-charged shocks and stabilizer bar, with lateral and diagonal lower links; the SRT-8 used Bilstein monotube shocks.
The rear suspension was a Mercedes-style five-link independent setup with coil springs, link-type stabilizer bar, shock absorbers, and isolated suspension cradle; the SE and R/T (with automatic) used gas-charged twin shock absorbers, while the SRT-8 used Bilstein monotube gas-charged shock absorbers, and the R/T with manual transmission used gas-charged monotube Nivomat load-leveling shocks. SE did not get the fancy chrome fuel filler door; and the SRT had a half-inch lower ride height. For 2009, SRT engineers fine-tuned suspension settings for both performance tires.
Four-wheel disc brakes were standard. Ducts in the front fascia cooled the front brakes. Each model had different pads.
- The Dodge Challenger SRT8 had Brembo four-piston calipers on all four wheels, for a 60 to zero mph stopping distance of around 110 feet.
- The Challenger R/T had twin-piston aluminum calipers and vented rotors in the front and single-piston aluminum calipers with vented rotors in the rear, for a 60 to zero mph stopping distance of around 125 feet.
- Finally, Dodge Challenger SE had single-piston aluminum calipers and vented rotors in the front and single-piston aluminum calipers with solid rotors in the rear, stopping from 60 in 130 feet.
Four wheel antilock brakes, traction control, and stability control with brake assist were standard on R/T, SRT8, and, with the Popular Equipment Package, on the SE.
The SE’s Popular Equipment Package also had 18-inch aluminum wheels, better tires, an eight-way power driver’s seat, fog lamps, luxury ﬂoor mats, leather-wrapped steering wheel and shift knob, security alarm, and dual-illuminated visor mirrors.
The popular equipment package for the R/T had leather, six-speaker stereo with big amp, satellite radio, heated front seats, “luxury floor mats,” keyless ignition, seatback map pocket, automatic headlights, and heated otuside mirrors.
Track Pak included a six-speed manual transmission, Hill Start Assist, anti-spin differential (3.73 w/18-inch, 3.92 w/20-inch wheels), and ESP full-off switch.
Dodge Challenger SRT8
The list price for the 2008 Dodge Challenger SRT8 was just under $38,000, including destination. Its performance, according to Chrysler; was:
- 0-60 in 4.9 seconds
- Quarter mile, 13.3 seconds
- Zero to 100 mph and back in under 17 seconds
- 60-0 braking of 110 feet
- Skid pad performance of 0.88 g
The Challenger SRT coupe, four inches shorter than the Charger and 300C, had a brake-lock differential, all-speed traction control, and specially tuned stability control. The manual transmission cost $695 - less than the gas guzzler tax. For 2008, each car had numbered dash plaques.
Inside, the Dodge Challenger SRT8 included leather seats with added bolstering and an orange accent stripe, stitched accents, tachometer, and 180 mph speedometer in the center, with Performances Pages that provide 0–60 mph times, 60–0 mph braking, g-forces, and quarter-mile time. It also included a 13-speaker Kicker audio system with a 322-watt amplifier and 200-watt subwoofer, and satellite radio.
For 2009, the Dodge Challenger SE started at $21,995, while the Challenger R/T started at $29,995, and the SRT-8 started at $39,995. Popular options, according to “CudaAAR,” included a sunroof, $950; MyGIG with GPS, $890; and high-performance tires, $50.
Dodge Challenger SE Rallye
For 2009, the new Challenger SE Rallye used the Hemi’s five-speed automatic transmission with the V6 (starting at $26,490). It also had 18 inch wheels, a spoiler, chromed fuel door, and faux carbon fiber interior accents. It was the first V6 Challenger to have accented dual stripes, to step up from a four-speed automatic, and the first Challenger (in general) to have deck lid stripes.
The five-speed automatic apparently cost one mile per gallon in city traffic, with the same highway mileage, but increased acceleration.
Dodge Challenger in person
The Challenger had an undeniable presence, whether up on a rotisserie, in photos, in video, or in person, and lent itself to “wild” and vibrant colors. Large yellow running lights provided a neat touch of color and a unique look. The full-length tail lit around a single backup-lamp bar.
It is amazing that the designers were able to get approval for the costly full-length tail-lights, the single-bar reverse light, and the real coup de résistance, the separate sidelights (later copied by the Camaro) and dual-headlight-style grille. The main battle, though, was reportedly to get approval for the grille without the trademark Dodge crosshairs.
Christopher Nowak, senior manager of the RWD product team and lead engineer on the Challenger “base car,” enthused about the combination of ride and handling; the SRT8 Challenger was also a better daily driver than past SRT8s, due to new tuning of the suspension.
We found the R/T and SE seats to be comfortable and supportive, with a more classic appearance and less aggressive side bolsters than the SRT8. Getting into the back seat was fairly easy from the passenger side, thanks to the high position of the seatback tilt-n-slide control, though one had to duck under the seat belt (or disconnect it from its seat loop). The driver’s seat had no tilt-and-slide control.
The interior of each model had subtle changes, including pattern changes; the R/T lacked the SRT’s performance metrics, and the SE had a dechromed logo above the glove compartment.
Dodge Challenger Suspension
The Dodge Challenger was a unibody design, as one would expect, with a multilink short and long arm (SLA) front suspension set in a cradle (made of hydroformed steel tube side rails with a stamped box-section lateral member).
The Dodge Challenger SRT8 used a five-link rear suspension; movin from the prior multi-link Chapman strut system reduced the unsprung mass. Decoupling left and right wheels improve tire contact while stabilizer bar attachments to the knuckles reduced lean. For 2008, SRT-exclusive fully-forged 20-inch Alcoa aluminum wheels with 4-season Goodyear Eagle RS-A tires were standard; three-season Goodyear F1 Supercar tires were optional.
In both front and rear, multiple links maintained independent control of camber and toe.
Electronic control and engine torque management were used to smooth full-throttle launches, quicken wide-open-throttle up shifts, and allow two-step kick-down shifts.
All four wheels had red Brembo four-piston calipers, with 360 x 32mm vented rotors up front and 350 x 26mm vented rotors in the rear. When the stability control registers over .6 g, the pads automatically went closer to the discs for instant action.
The drag coefficient of 0.353 (9.01 CdA) was fairly high for a modern car, and similar to the 300C SRT8 (at 0.355).
Dodge Challengers in Canada: SXT, SRT8 500, and more
Canadian buyers had two unique models: the Dodge Challenger SRT8 500 and SXT (thanks, Geo Nazos). The SXT was the SE with an option package. The SRT8 500, only available for 2008, had a certificate of authenticity, carbon fibre hood striples, Kicker 13-speaker audio, 6-disc DVD radio, UConnect, alarm, and badging.
2008 Dodge Challenger styling and such
Jeff Gale, the famed Tom Gale’s son, led exterior design. He said, “We used the original Challenger as an inspiration. The side mirrors actually started with a mold from the mirrors of an original Challenger. We tweaked a few details for fit and finish, then put them through our modern aerodynamic testing metrics and ended up with a body-mounted mirror that is remarkably similar visually to the original, but offers significantly better aerodynamic performance.”
Brian Nielander, manager of design for the Dodge Challenger, wrote that many interior themes were based directly on the original 1970 Dodge Challenger. Inside, the Challenger used the new chrome-ringed climate controls, which are both attractive and functional; the performance indicators were in the lower half of a gauge pod.

One Lap of America
Mopar Action’s Rick Ehrenberg once won the One Lap of America in his Plymouth Duster. Some may remember the film Vanishing Point with its white Dodge Challenger. The two were put together in 2008 by Ralph Gilles and vehicle dynamics supervisor Erich Heuschele with a modified pre-production SRT8; however, after a good result on the skid-pad, they lost control of the Challenger around a turn and crashed it badly enough that it was no longer in the running.
Repairs and issues
TSB 18-006-09, dated February 11, 2009, notes that a computer “flash” upgrade is free, under warranty, for customers with 6.1 liter engines and manual transmissions built before February 6, 2009 (MDH 0206xx). This prevents unnecessary engine-light activation for cylinder 7 misfires (P0307) and may prevent the misfires themselves, smoothing the idle.

For 2010, the five-speed automatic finally replaced the four-speed across the board, and a deceleration fuel cutoff was implemented. Super Track Pack was an R/T option with the manual transmission, including summer tires. Stability control was standard on all models; automatic headlights with LED cup holder and door-handle lights were standard on R/T. Changes to the Challenger SRT8 were new limited edition Plum Crazy and Furious Fucshia models, serialized dash plaque, and plum accent seat-stripe insert.
The Hemi had a six-speed manual option which achieved the same gas mileage as the automatic. There were also a late-availability Super Track Pack option for R/T, UConnect multimedia with Sound Group I and II, steering wheel audio controls with Multimedia and Navigation, standard stability control on SE, and automatic headlights with LED cup holder and door-handle lights standard on R/T.
The long-rumored 6.4 liter engine with cylinder deactivation showed up for SRT, midyear.
2008-09 Dodge Challenger sales figures by color, model, and transmission
For 2008, 7,051 Dodge Challengers (all SRT8 models) were built for North America: 6,400 for the US, 500 for Canada, 151 for Mexico. 4,137 were orange, 2,207 were black, and 708 were silver. (Geographical distribution was posted at Allpar and both geography and color were printed by Mopar Muscle.)
SE is LCDH22, R/T is LCDP22, SRT8 is LCDX22. Some of these colors (e.g. B5 Blue) were not generally available or were only available for part of the year. Hemi Orange and B5 Blue were not available on Challenger SE. The four-speed automatic was dropped for the 2010 model year. Many thanks to Mike V. for providing this information.
|2009 Challengers||4-Speed||5-Speed Automatic||6-Speed Manual||Total|
|Deep Water Blue||951||3||898||901||450||450||2,302|
Total by model: 8,031 Challenger SE; 14,883 Challenger R/T; 8,586 SRT8.
The Brampton facility made the Dodge Challenger, Dodge Charger, and Chrysler 300C on one line. Forty-two robots were added in the Body Shop to weld the Challenger’s unique body sub-assemblies.
Pre-production cars were built and tested on the regular assembly line, without interfering with production. Flexible manufacturing of this type was first used in the launch of the 2001 minivans at the Windsor Assembly Plant.
