2016 Dodge Viper ACR First Drive [w/video]

The Dodge Viper is not a comfortable car. Livable, yes. The interior is covered in fine materials. But you still climb over a hot door sill to enter the tiny cabin. And the frequency range of the engine's noises seem specifically designed to cause headaches. What happens, then, if you remove all pretense of civility from a Viper and add equipment solely aimed at improving lap times? You would have the 2016 Dodge Viper ACR. In terms of achieving its purpose, this car is a absolute success. In many ways it's also the most honest Viper of the current generation. Prices start at $121,990 (including $2,100 gas-guzzler tax and $1,995 destination), or $32,900 more than the least expensive Viper. In ACR trim, the Viper loses the under-carpet padding, 9 of 12 speakers plus amplifier, carpet and trim from the cargo area, and sound deadening in front of the rear wheel wells. The parts of the interior still covered add healthy amounts of Alcantara or optional carbon fiber. That weight loss is compensated by the addition of go-fast bits like the giant rear wing (or the larger "x-wing" on the Extreme Aero Package), 10-way adjustable Bilstein Motorsports shocks, Brembo carbon-ceramic brakes, a rear diffuser, and a front splitter. Total claimed curb weight is 3,392 pounds in Aero trim (standard ACR trim is 18 pounds lighter), which is within a few stone of the rest of the Viper lineup. The diffuser strakes and leading edge of the splitter are removable, made to be replaced after rubbing on track tarmac and make street driving slightly more practical. Not that you'd want to drive the ACR on the street, with the lack of noise insulation and spring rates twice as stiff as the Viper TA, but it is street-legal. Dodge claims the DOT-approved Kumho Ecsta V720 tires on the ACR allow faster lap times than some race compound tires. Our test was limited to on-track shenanigans at Virginia International Raceway. Which is fitting because we wouldn't have anything good to say about driving the car on the street. The ACR is, essentially, a race car sold in the showroom, although with the Viper's 1 of 1 customization program, your custom build can include as many creature comforts as you like. Lined up in pit lane at VIR, the Viper ACRs for our evaluation blur the air with heat shimmer. All of the test cars have air conditioning, but that shuts off at full throttle with a six-second reset.

The Dodge Demon was developed under a cloud of smoke

The Dodge Demon needs no introduction. The car is so full of superlatives that most of it sounds unbelievable until you see and hear it in action. The car was revealed after months of teasers and cryptic messages, but the public weren't the only ones in the dark. From the start, the Demon's development was a closely guarded secret. There were even some within SRT that didn't know about the project. The people behind the car went through a lot of effort to keep it that way. At an event covering the finer details of the Demon's supercharged 6.2-liter V8, Dodge CEO Tim Kuniskis and SRT Powertrain Director Chris Cowland spoke about the smoke and mirrors used to hide the Demon's development. Work on the car progressed for nearly two years before it was made public, with just a small team having full access to the project. Numbers were altered. Secret meetings were held. SRT engineers worked nights and weekends while parts suppliers were given as little information as possible to move progress forward. Preliminary work on the Demon began in April of 2015, not long after the standard Hellcat hit the streets. The goal wasn't to create a faster Hellcat. Kuniskis said that would have been easy. They wanted a single-minded vehicle that could also be driven on the road. It's the same mindset that brought about the Dodge Viper ACR. Dodge wanted a car that could sell the brand to both enthusiasts and non-enthusiasts alike. 840 horsepower is going to raise anyone's eyebrows, including the Camry owner parked down the street. While preliminary work started in April, the final greenlight wasn't given until September. The project was originally going to revive the American Drag Racer, or ADR, name. When we saw the first hints of the Demon last fall, we labeled the spy photo above the Dodge Challenger ADR. It was set to have 10-percent more power and 20-percent more launch force than the already gut-punching Hellcat. It was also only going to have a quarter-mile time in the 10s, just slightly quicker than the Hellcat. Somewhere along the line, the team realized that the ADR wasn't enough. It was just going to be a Hellcat plus, and that wasn't exciting. The main goal was changed: 9s with light. Translated, that means a 9-second quarter mile with light under the tires (read: a wheelie). From that point forward, everything about the Demon's development, from power to suspension to weight, would be done in pursuit of that goal.

Dodge Viper to out-Hell the Hellcat with supercharged V10?

The Viper wouldn't be the Viper if it wasn't the most powerful model under the Chrysler umbrella. But with the arrival of the Hellcat engine in the Dodge Charger and Challenger, the Viper has fallen behind in the bragging rights department: where the new supercharged V8 produces 707 horsepower and 650 pound-feet of torque, the naturally aspirated V10 offers "only" 640 hp and 600 lb-ft - gargantuan output figures by almost any other standard, but crucially behind on the SRT power scale. Conner Avenue is going to have to do something about that.
Although the Hellcat's engine reportedly won't fit under the Viper's hood, SRT is now rumored to have another trick up its sleeve: supercharge the existing V10. According to the Pentastar performance enthusiasts at allpar.com, Chrysler has already taken delivery of the first such prototype engines so that it can begin the process of fitting it into an upgraded Viper.
The spooled ten-pot is tipped to produce around 800 hp and 650 lb-ft of torque. More than that and the Viper's drivetrain, chassis and bodywork would have to be substantially reworked. Though beefier transmissions are available, fitting them would reportedly set off a domino-game of changes required to handle the added torque. Which may be something Chrysler would be prepared to do for the next-generation model, but in the meantime, 800 hp could prove enough to put the Viper back atop the Mopar performance ladder where it belongs, and give it an edge against the new Corvette Z06 to rekindle sales.
