2015 Dodge Challenger SRT Hellcat (pictures)

The 2015 Dodge Challenger SRT Hellcat is claimed to be the most powerful muscle car ever produced.

The model makes up for its slightly smaller engine with the addition of a supercharger.

The twin-screw type supercharger crams air into the engine.

The scoops and vents on the hood aren't purely aesthetic, they push and pull air into the engine bay, cooling the hot powertrain.

With the aid of the supercharger, power jumps to an unbelievable 707 horsepower and 650 pound-feet of torque.

A cold-air intake hides within a hollow daytime running light.

The Hellcat comes with two keys: a black key that limits power to 500 ponies and a red key that unlocks the full potential.

SRT electronics allow the driver to customize the performance for road and track.

The SRT pages portion of the standard Uconnect 8.4 infotainment system allow the driver to customize and toggle four different drive modes.

Launch control is standard and helps the Hellcat to hit 60 mph from a standing start in just 3.5 seconds.

Or if burnouts are more your thing, the traction control can be disabled and the tires shredded.

The Hellcat has a top speed of 199 mph and does the quarter mile in 11.2 seconds on the sticky street tires.

The sound this coupe makes at full bore is a terrifying mix of V-8 roar and mechanical supercharger whine.

The Hellcat also features an adjustable suspension with 3 settings.

The Street setting is actually quite comfortable, while the Track setting keeps things firm in the corners. Sport splits the difference.

20-inch wheels are standard and filled with massive Brembo brakes.

Expect to be seeing this fuel cap a lot. I only averaged 11.9 mpg during my testing.

What surprised me is that the Hellcat is quite easy to drive on public roads and in traffic.

The engine is louder than the stereo at full bore, but also extremely quiet at highway speeds.

The interior is a mix of cheap plasticky bits and nicer touch points.

These optional Laguna leather seats feature heated and ventilated surfaces.

The steering wheel is heated.

Paddle shifters are made of a lightweight aluminum and are more pronounced than those of the standard SRT.

I'm not a fan of the plastic, "faux turned metal" trim surrounding the instrument cluster and center console, but was pleased with the rest of the cabin trim.

Push-button start and keyless entry are standard.

Instrumentation features a pair of red-faced gauges flanking a large color display.

The center display and the supercharger are the only places where I saw any Hellcat badging.

The Uconnect 8.4 infotainment system is standard and features a well-rounded list of digital audio sources.

Navigation is a $695 option that's worth every penny. Voice command is top-notch and routing is also good.

At the rear, you'll find attractive LED taillights and a black SRT lip spoiler.

Other standard safety bits include a rear camera, audible parking proximity alerts and cross traffic alerts, and blind-spot monitoring.

The Challenger SRT Hellcat is intimidating and immensely powerful, but fairly easy to live with... that is, if you can afford to keep the tank filled.

There's nothing like the Challenger SRT Hellcat being built today -- at least, not until the 2015 Charger SRT Hellcat arrives with two more doors and the same 707 horsepower.
