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.

Dodge Demon's A/C helps its supercharged Hemi make more power

Staying cool is one important key to performance. Simply, more air means more power, and cool, dense air is better than hot air. While forced induction might help make copious amounts of horsepower, turbos and superchargers produce heat. Intercoolers help, but the new Dodge Demon and its supercharged Hemi need a bit of an extra boost. In Drag Mode, the Demon's engine commandeers the car's air conditioning system to help chill things out. The Demon will have the first production application of a liquid-to-air charge air cooler chiller system. Literally, the car's air conditioning system is used to cool the air going into the engine, dropping temps by up to 45 degrees Fahrenheit. Dodge claims the system helps achieve "temperatures previously unattainable by pressure-charged street-legal production vehicles." As cool as this may sound, the technology isn't new. Ford had a prototype system in the early 2000s called SuperCooler, though that system never made it to production. While the Demon's system doesn't have a super cool name like the one from Ford, the pair essentially work in the same way. In theory, it should have the same effect as a bottle of nitrous. According to Autoweek, Ford's system bumped up the output of the F-150 Lightning by about 50 horsepower. Turns out that air conditioning isn't always a huge power suck. Related Video:

1968 Dodge Super Charger is a super Charger with a supercharger

Mopar's latest custom creation is sure to be in the running for coolest car at this year's SEMA show. It's a 1968 Dodge Charger, a car selected in part because this year marks the car's 50th anniversary, but taken to the extreme and renamed Super Charger. The headliner of the car's radical upgrades is the new "Hellephant" engine. It's a take on the original car's 426-cubic-inch Hemi V8. But this new engine, with the same displacement, is based on the current Hemi V8, and adds a supercharger. All told, it makes a whopping 1,000 horsepower and 950 pound-feet of torque on 93 octane pump gas. It will be available as a crate engine, too. The engine is far from the only impressive change to the car. All over the body are mild to wild tweaks. The wide, uninterrupted grille from the original is still here, but it's a one-piece example now. And instead of hiding the headlights behind doors that have to open for illumination, the lights simply shine through the grille, retaining a clean look even at night. The whole car sits 2.5 inches lower than stock, and it's now four inches wider thanks to the huge fender flares. They house 305-mm-wide tires up front, and 315-mm tires in the rear. Likely the most complicated change to the car is the lengthened wheelbase. There are two more inches between the wheels now, something Mopar did to reduce the front overhang. A close second in complexity are the taillights. They're the same shape as the originals, but now the round elements are actually exhaust outlets. The tips also happen to be the same as those on the Alfa Romeo Stelvio. There are other details that help bring together the exterior. The rain rails have been smoothed out on the roof, the vent windows removed, special 426 stickers have been added, and the fuel door now has a Hellephant badge with a blue background with lots of little Mopar Ms. The interior gets some attention, too. The rear seat has been removed, Dodge Demon style. It gets a custom roll bar designed to be as unobtrusive as possible, even getting the hoop around the seats to roughly line up with where the windows meet. Gauges come from the Mopar catalog, and the steering wheel and seats are from the dearly departed Dodge Viper. They're particularly relevant, as the six-speed manual transmission comes from the Viper, too. Related Video: This content is hosted by a third party.
