It’s finally here, the new 600-plus horsepower 2015 Challenger SRT with a Hellcat engine. The Challenger SRT Hellcat features the most powerful V-8 engine ever produced by Chrysler – the supercharged 6.2-liter Hemi V-8.
“The new 2015 Dodge Challenger SRT Hellcat is the ultimate performance muscle car,” said Tim Kuniskis, President and CEO – Dodge Brand, Chrysler Group LLC. “Dodge is the Mainstream Performance brand, and now combined with SRT, we are able to unleash a true GT car with an all-new driver-focused interior and the TorqueFlite eight-speed transmission combined with the most powerful V-8 Chrysler has ever produced. The Challenger Hellcat has been released!”
Power to Spare
For 2015, the Challenger SRT with a Hellcat engine is propelled by the new supercharged 6.2-liter Hemi. With more than 600 horsepower, it will be the highest of any V-8 engine in Chrysler’s history. The all-new V-8 engine can be mated with an upgraded six-speed manual transmission or a beefy, new TorqueFlite eight-speed automatic – the first such gearbox ever offered in the Dodge Challenger SRT’s time-honored segment.
The supercharged engine features a forged-steel crankshaft with induction-hardened bearing surfaces. According to Chrysler, the result is a crankshaft so well-engineered, that it can withstand firing pressures of 110 bar (1,595 psi) – the equivalent of five family sedans standing on each piston, every two revolutions. For you race guys, an SFI approval is sure to happen, with its unique, crankshaft damper that has been tested to 13,000 rpm. Inside, high-strength, forged-alloy pistons connect to powder-forged connecting rods with high-load-capacity bushings, and diamond-like-carbon-coated piston pins. The new supercharged 6.2-liter Hemi has aluminum-alloy cylinder heads that are optimized for superior thermal conductivity. And its die-cast aluminum rocker covers are Hemi Orange.
Never worry about letting Junior borrow the car. The 2015 Challenger SRT with a Hellcat engine comes standard with two key fobs – one is red, and the other is black. The red key fob is the only key that can unlock the full horsepower of the Hellcat engine, while the black key fob limits the driver to a reduced engine output.
When Valet Mode is activated, the following vehicle configurations are enabled:
• Engine is remapped to significantly reduce horsepower and torque; limited to 4,000 rpm
• Transmission locks out access to first gear and upshifts earlier than normal
• Transmission will treat the manual shifter position the same as the drive position
• Traction, steering and suspension are set to their “Street” settings
• Steering-wheel paddle shifters are disabled
• Drive Mode functions are disabled
• Electronic Stability Control (ESC) is enabled to Full-on
• Launch Control is disabled
Standard wheels on the Challenger SRT with the Hellcat engine are new SRT-exclusive “Slingshot” 20 x 9.5-inch, lightweight forged-aluminum wheels with a matte black finish; available on the SRT 392 as part of the SRT Track Pack. New P275/40ZR20 Pirelli P Zero Nero tires (front and rear) provide all-season traction while the newest tire technology from Pirelli includes the class exclusive four-season tire that is Y-Plus rated to handle the extreme speeds. Pirelli P Zero tires are available for three-season performance driving. Optionally available on the Challenger SRT Hellcat are 20 x 9.5-inch, lightweight forged-aluminum wheels with a Brass Monkey/dark bronze finish.
Standard is the largest front-brake package ever offered in an SRT vehicle, featuring all-new 390-mm (15.4-inch) Brembo two-piece rotors with six-piston calipers. This upgraded brake package is available on the 392 Hemi SRT model as part of the SRT Track Pack.
Getting the Look
Designers and engineers spent a lot more time (35 percent more in fact), time in the wind tunnel, developing the exterior on the Challenger SRT and Challenger SRT Hellcat. Chrysler says that the result is a re-engineered Challenger capable of maximum aerodynamic performance for spirited driving on the road or the race track. Up front, a new fascia design and an all-new vertical-split grille provide an update of its 1971 inspiration. A larger, power-bulge aluminum hood features a dedicated “cold-air” intake – a visual styling cue from the first Viper coupe built in 1996. The hood on the new Challenger SRT with a Hellcat engine also includes dual air extractors to ensure effective removal of heat and reduced air turbulence in the engine compartment. The hood is standard in body color, and is available in a Satin Black finish.
Another key design element on the Challenger SRT Hellcat is the Air Catcher inlet port, which feeds ram-air directly into the engine air box through the driver-side parking lamp. Finally, The Dodge Challenger SRT with a Hellcat engine features a larger front splitter designed for optimal down force to minimize lift.
Out back, the 2015 Challenger SRT recalls the historic 1971 model’s styling with a new split tail-lamp design and rear fascia. A redesigned rear valance helps the 2015 Challenger SRT models look more planted on the ground. A unique, taller rear spoiler on the SRT Hellcat features a raised SRT logo.
There is an all-new cockpit with key elements are inspired by the interior of the 1971 Challenger. The all-new instrument panel features a stamped aluminum bezel, and a 7-inch driver-selectable information display (DID) screen is centered in the gauge cluster. The screen is flanked by analog speedometer and tachometer gauges, which give a retro look, reminiscent of the gauges from the 1971 Challenger. For the Challenger SRT with the Hellcat engine, the fixed gauges and digital graphics are finished in a Dark Radar Red tone to make it even more unique.
High Impact is Back
Many of the most memorable paint colors in automotive history have been found on the Challenger. The 2015 Challenger SRT 392 and SRT with the Hellcat will be available in 11 exterior colors: B5 Blue Pearl Coat, Billet Silver Metallic Clear Coat, Bright White Clear Coat, Granite Crystal Metallic Pearl Coat, Ivory White Tri-Coat Pearl, Jazz Blue Pearl Coat, Phantom Black Tri-Coat Pearl, Pitch Black Clear Coat, Redline Tri-Coat Pearl, Sublime Metallic Pearl Coat and TorRed Clear Coat.
Twin, full-body stripes are available in Black Satin Gloss and Silver High Gloss on the SRT 392.
So there you have it, the Hellcat is here, and you can bet that the Ford and Chevy camp are looking at the end of their world…
