2015 Dodge Challenger cars: muscle is back

challenger scat pack

Every 2015 Dodge Challenger’s automatic transmission has eight speeds, from the base 305-horsepower V6 to the top 470-horsepower 392 Hemi V8; both V8s can have a six-speed manual, too. See 2015 Dodge Challenger specifications for model and engine details.

The big 6.4-liter Hemi, exclusive to SRT in the past, is now available in the new 2015 Dodge Challenger Scat Pack model. While the car looks similar to the 2014, aerodynamic drag has been cut from 0.356 to 0.337; and the former SRT Performance Pages, with acceleration and skidpad times and more, are now the Dodge Performance Pages, available on all Challenger trim lines (standard with 6.4 or Super Track Pack).

392 engine

Dodge Challenger Scat Pack

The Challenger Scat Pack’s 6.4 Hemi has both 470 horsepower and 470 lb-ft of torque, with a relatively flat torque curve for responsiveness and strong performance through the engine’s speed range. An active intake manifold, high-lift cam, and cam phasing provide better low-end torque and high-end power. For a touch of nostalgia, the engine block is lacquered in HEMI Orange paint.

392 shaker

The Tremec TR6060 six-speed manual transmission is standard with the 392, the eight-speed optional; all Hemi engines operate on four cylinders when possible, but only when equipped with the eight-speed. See 2015 Dodge Challenger specifications for gear ratios.

scat packThe new active exhaust system on the Dodge Challenger 6.4-liter Scat Pack and 392 HEMI Scat Pack Shaker allows for straight-through mid and rear mufflers for a throaty exhaust note under engine load. Even with up to 26 percent more horsepower than the 5.7-liter HEMI V-8 engine, this range-topping 6.4- liter HEMI V-8 engine with active valve exhaust system helps the four-cylinder mode Fuel Saver Technology (with eight-speed automatic transmission) engage over a wider rpm range.

The Dodge Challenger 6.4-liter Scat Pack and 392 HEMI Scat Pack Shaker have Bilstein high-performance shock absorbers and unique suspension geometry (including lowering the body by half an inch) to improve cornering and responsiveness. Dodge claims the Dodge Challenger 6.4 Scat Pack and 392 HEMI Scat Pack Shaker are capable of 0.93g on the skid pad – on par with some of the world’s best-handling cars.

bee gauges

Black four-piston Brembo calipers at each corner, with 14.2 inch (front) and 13.8 inch (rear) vented/slotted rotors, help bring the Dodge Challenger Scat Pack cars from 60-0 mph in 117 feet. Brake cooling and reduced fade were enhanced by wind tunnel testing and ducts that direct air to the rotors.

New 20-inch lightweight alloy wheels with Goodyear Eagle F1 three-season performance tires are standard, with Goodyear Eagle RS-A all-season performance tires a no-charge option.

TorqueFlite Eight

shiftersThe celebrated TorqueFlite Eight gearbox, previously unavailable on Dodge Challenger at all, is now available with all three engines; it comes with a new “T-grip” electronic shifter, designed to feel like a normal shifter rather than an electronic toy.

Chrysler introduced its eight-speed automatic transmissions in 2011, and remains the only automaker to use them with mainstream brands. On its own, in the Challenger, it accounts for a fuel-economy boost of 5%-9%... with faster acceleration, thanks to the large 7.03 ratio spread. First gear is a low 4.71:1; high gear is a tall 0.67:1. That allows for both fast launches and low engine speeds on the highway, especially with the torque of the big Hemi. Yet, at 194 pounds, it weighs just four pounds more than the old five-speed Mercedes gearbox. Details, gear ratios, etc.

In the new Sport mode, shift times are slashed by 40%, and are moved to higher engine speeds; four-cylinder mode is also dropped in Sport mode.

The gearbox automatically senses and adapts shift patterns for:

  • engine torque gradients
  • longitudinal and lateral acceleration
  • grade steepness
  • friction
  • temperature
  • cruise control
  • electronic stability control activation

392 engine

For the moment, the 845RE version used by the V6 is made by Chrysler, with the HP70 used with V8s made by ZF itself in South Carolina. Chrysler is expected to slowly take over production of the V8 eight-speeds as well.

The new shifter, which maintains tactile feedback, has a manual override gate, but buyers can also get paddle shifters on the steering wheel, as in the past.

Dodge Challenger upgrades from 2014

performance pages

performance pagesThe Dodge Performance Pages let drivers access the active launch control, launch control RPM settings, programmable and adjustable shift light and RPM settings, performance timers, and performance gauges, such as G-force indicators and engine performance.

These features were once exclusive to SRT, but are now available on all trim levels of the Challenger, as an option, with the Super Track Pack, or standard.

The Pentastar V6 used in Dodge Challenger is the most powerful version of that engine at Chrysler Group, thanks partly to a cold-air induction system and dual exhausts from the headers back to the exhaust tips; 90% of the engine’s peak torque is available from 1,800 to 6,400 rpm.

Challenger R/T has the 5.7-liter HEMI V-8 engine, with up to 375 horsepower and 410 lb.-ft. of torque (with the manual; the automatic drops the numbers to 372 hp and 400 lb-ft). When paired with the Tremec TR6060 six-speed manual, the Dodge Challenger R/T have a performance-tuned dual exhaust with low-restriction bottle resonators. 0-60 mph runs have dropped to the mid-5-second range with a sinister exhaust growl.

Super Track Pak is now available on every model, and standard on R/T Shaker. It adds performance suspension tuning, a high-performance brake package, high-performance steering, 3.07 (or 3.08?) rear-axle ratio (to V6), and 20-by-8-inch cast-aluminum Hyper Black II wheels with P245/45ZR20 BSW Goodyear F1 three-season tires (Goodyear RSA all-season performance tires are a no charge option). The package also includes Dodge Performance Pages.

head onThe steering-column-mounted electric power steering (EPS) system improves handling and performance, by modulating power assistance according to driving conditions; it is up to 3% more efficient than hydraulic systems, and reduces maintenance and repairs. The system is integrated with the stability control to help compensate in split-traction, torque steer and pull-drift (crowned road) situations.

New cast aluminum axles and housings replace the 2014s’ steel structures, saving weight. A new four-bolt design replaced the three-bolt pattern of prior years, too, to cut friction and increase durability.

The front suspension is mounted in a rigid, light cradle made from tubular steel. Premium hydro-bushings, monotube shock absorbers, and a lower-front-shock-to-suspension-link bushing increased control, ride and comfort.

The 2015 Dodge Challenger’s five-link rear suspension design continues, with roll-steer geometry for independent control of camber and toe suspension movement. The hydroformed steel rear suspension cradle isolates the passenger compartment from road and axle noise, vibration, and harshness. Monotube shock absorbers, urethane jounce bumpers, and suspension links with rubber shock absorber bushings all work together to deliver ride and comfort, while upper and lower spring-seat isolators provide additional dampening to smooth over bumps.

The camber is set at -1.0 degrees in the front and -1.75 degrees in the rear for high-speed cornering, with tires leaning inboard at the top relative to the body.

So how’d we do? JackRatchett used spy photos and rumors of 1972 rear styling for this rendering.

Styling and Design

While the 2008-2014 Challenger followed the design language of the original 1970 Challenger, the front of the 2015 Dodge looks to the 1971 car (the tail is actually taken from the 1972). The larger power-bulge hood has more aggressive dual snorkel inlets for engine cooling, while the split-grille was inspired by the 1971 car. Other changes include moving the windshield washer outlets under the hood, using new quad halo projector headlamps and a more aggressive brow, a wider trapezoidal front air dam and slimmer grille, pushing the projector fog lamps to the corners, and using a new duck-bill fascia spoiler. These moves were made to emphasize the car’s width, improve cooling, and cut wind drag.

four challengers

From the side, the sills have been re-tuned in the wind tunnel to improve aerodynamics. Nine wheel designs are available, including 18-inchers on the SXT and 20-inchers on the R/T. A new lightweight 20-by-9-inch forged aluminum wheel in matte black is optional on R/T and Scat Pack.

halo headlamps

In back, the 2015 Dodge Challenger recalls the 1971s with a new split tail-lamp design and rear fascia. The tail-lamps have smoothed-out LED lights. A redesigned rear valance makes the 2015 Challenger look more planted on the ground. For enthusiasts who plan on adding a performance exhaust, the exhaust is mounted tightly below the valance and is cut out for larger exhaust tips.

T2015 Dodge Challenger will be available in Bright White, Pitch Black, Granite Crystal, Billet Silver, Jazz Blue and Redline Red. Premium three- coat colors include Phantom Black Tri-Coat Pearl and Ivory White Tri-Coat Pearl; B5 Blue, TorRed and Sublime Green will be “available for a limited time.”

stripes

fuel capNew heritage-inspired stripe options from the factory include a body-side stripe (SXT), R/T-logo glossy black hood stripe, and a body-side glossy black or white or glossy red stripe (R/T Classic). For Challenger Scat Pack, there can be rear-quarter Bumble Bee stripes; on Shaker, Shaker graphics with a matching black spoiler and fuel door.

R/T Shaker models (with Shaker hoods) will enter production in 2015.

Inside the 2015 Dodge Challenger

dashboard

Designers tried to merge modern technology with the “essence of the 1971,” providing a driver-oriented cockpit surrounded by a stamped aluminum bezel. As with Dodge Charger (and various other Chrysler Group cars), a seven-inch screen provides a customizable display (details). A new speedometer and tachometer use a retro design, bringing memories of the “tic-toc-tach” gauges from the 1971 Challenger. The center stack houses the new standard 5.0-inch and optional 8.4-inch Uconnect touchscreens.

gauges

With its unique elevated design, the center console has redundant button and knob controls for audio and climate control. A new media hub with an SD card slot, USB outlet, and audio jack is n the armrest.

The steering wheel is new, and provides a better grip at the 3:00 and 9:00 positions, with optional paddle shifters and large, backlit controls for the configurable gauges. UConnect and phone buttons are now on the bottom edge of the spokes; audio controls remain on the back. The new tilt-telescoping steering wheel also has a 360- degree heat element.

dash detail

The seats have been redesigned, with better cushioning and contours; the passenger seat now has an exit/entry function for access to the rear seat. Performance seats have large side bolsters for maximum lateral support. Heated and ventilated front seats are standard when Nappa leather is ordered.

Dodge Challenger has kept its best-in-class rear head room (37.4 inches) and legroom (32.6 inches), providing class-exclusive seating for five, and best-in-class cargo space (16.2 cubic feet).

Electronics, stereos, and gadgetry

The 2015 Dodge Challenger features UConnect Access via Mobile, along with similar safety features as the 2015 Dodge Charger.

What about the HellCat V8?

The rumor mill claims that the SRT Challenger will add a 6.2 liter supercharged Hemi to the engine list, in a limited edition car, set to cost twice as much as standard Challengers, but ready to beat the hottest Camaros and Shelby Mustangs (which are in the same price range). When — and whether — this car will be produced is still a matter of conjecture; but the 2015 Dodge Challenger is set for production this summer.

Allpar has previously reported that the car would have an eight-speed automatic behind a supercharged 6.2 Hemi, good for 620-680 horsepower (and up to 640 lb-ft of torque, limited by the automatic; a rumored manual transmission may allow more torque). Direct competitors would be the Shelby GT500 and Camaro ZL1/Z28.

supercharger

“Danno” wrote that fog lights on the supercharged cars will be sacrificed in favor of a “wind tunnel,” which will take incoming air past oil and coolant coolers (one on each side) and eject it through openings in the wheel-wells. Engine air will enter through the front, go into the blower, then be sent up through runners to heat exchangers, moving down into the intake ports.

engine

The SRT 392 will be differentiated from the 6.2 by wheels, badges, and perhaps a different hood. The supercharged 6.2 will be positioned against similar GM and Ford cars, which run to over $70,000, but will have more interior space and better amenities, and possibly better performance despite its larger size. Pricing is unknown, but we don’t expect it to run under $75,000.
