SR Auto Group draws controversy with green Dodge Challenger Hellcat

Article by Christian Andrei, on October 21, 2015

Canadian tuner SR Auto was tasked with decking out this Dodge Challenger Hellcat to the maximum. The tuner did not disappoint, managing to turn this authentic American muscle car to something even more powerful. The styling has veered quite a bit off the usual path though.

Employing an Airrex air suspension system, SR Auto effectively lowered the car to the ground. The system used a compressor that was installed directly into the car’s trunk. From the compressor, the team installed pressure lines on all four corners of the trunk.

Exterior upgrades included a Liberty Walk body kit, and 20-inch PUR LG05 wheels for both the front and rear. The front wheels measured 20x11 inches while the rear had 20x12 inch wheels. Both come adorned with a matte black diamond face.

Of course, since it was given a Liberty Walk body kit, the front and rear bumpers of the Challenger were upgraded. This new model reportedly took the Dodge and SRT teams 35% more time to work on than previous Dodge Challenger SRT. Work took place in the Chrysler Group's full-scale wind tunnel in Auburn Hills, Michigan. Going back to the 1971 Challenger-inspired exterior design, Dodge decided to upgrade the vertical-split grille found in the 1971 Challenger and to install it on the 2015 Challenger.

The new model also features a dedicated cold air intake. This upgrade is based on the visual styles of the 1996 Viper coupe. Finally, the front part of the monster vehicle features a power-bulge hood made 100% out of aluminum. In addition, Dodge engineers have equipped the Dodge Challenger SRT with dual air extractors.

This works to reduce air turbulence and facilitate heat shedding in the engine, and is designed to work with the Hellcat engine. Aesthetically, the hood comes in a Satin Black finish. As part of the company’s weight-saving efforts, the Challenger SRT’s hood is also constructed wholly in aluminum.

Dodge has also chosen to install its exclusive Air Catcher inlet port in the Challenger SRT Hellcat. The port’s purpose is to act as an intake for ram-air. The ram-air then goes through the driver side parking lamp and straight into the engine air box.

Another highlight is a set of all-new quad projector headlamps, whose top portion feature a brow “chops” design. This is to add to the masculine essence of the Challenger. A close look at the lower corners of the Challenger 392 SRT will reveal integrated projector fog lamps.

The placing is strategic, as it provides to emphasize the width of the car while the headlamps are on. Aerodynamics is also improved with the Challenger 392 SRT, thanks to the new duck-bill fascia splitter.

Lift is reduced to a minimum when driving the Dodge Challenger SRT, thanks to the large front splitter design. This, however, is available only to the models that have the Hellcat engine installed. The new Challenger is visually prominent even from the side.

This is thanks to the muscular proportions that have become a signature of the Challenger, in addition to the large thruster rear-quarter panels. The look is completed by fender and belt lines at both the front and rear portions of the Challenger.

Better yet, the Challenger SRT Hellcat has its own “SUPERCHARGED” fender badges that set it apart from its Challenger buddies. Its proportions are highlighted by the use of black sills but their functions are more than aesthetic.

They have an aerodynamic function as well, as they have been tuned accordingly in the Michigan wind tunnel. The rear design of the 2015 Dodge Challenger SRT also takes cues from the visuals of the 1971 Challenger.

These include an updated design for the rear fascia and the split tail-lamp design. Anyone can spot the Dodge Challenger SRT from a distance, thanks to the signature LED graphic that has been incorporated into the tail lamp design.

Dodge had also redesigned the balance in the rear of the vehicle so it looks closer to the ground. The design is completed by a raised rear spoiler. The spoiler bears the logo of SRT.


As for engine power, information from Chrysler indicated that the 6.2 liter HEMI Hellcat engine can output 600 hp.

However, official information indicated a more powerful engine – it now gives out 707 hp and 881 Nm or 650 pounds per foot of torque. The new stats trumped the Dodge Viper’s 8.4 liter V10 engine with its all-aluminum engine that can only give out 640 hp.

For torque, the Viper’s engine is only at 600 pounds per foot or 813 Nm. In addition, the 2015 Challenger has red and black key fob options for interested buyers. Installing the black key will make the Challenger a little tame, at only 500 hp of power.

However, the red key fob allows the Challenger to access its full engine potential of 707 hp. The 2015 model of the Challenger also includes a re-engineered design and interior scheme, which takes its lead from the 1971 model of the Challenger.

For those who want a little less power than the one offered by the Hellcat’s V8 engine, you have an alternative. This is the Pentastar V6 engine. It offers only 300 hp and returns around 30 mpg. The engine is very fuel efficient, and offers an eight-speed transmission gearbox.

Dodge is also offering the 2015 Dodge Challenger R/T. It is powered by a 5.7-liter HEMI engine, and is offered with eight-speed and six-speed manual options. There is also the 6.4-liter HEMI Challenger Scat Pack.

It has a horsepower rating of 485, and torque of 485 hp and 475 lb-ft (644 Nm). All of these points to the fact that Dodge and engineers from SRT have decided to take more time to refine the Challenger SRT and Challenger SRT Hellcat.
