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.

2016 Dodge Viper ACR is ready to take a bite out of the Corvette Z06 [w/video]

The Dodge Viper ACR is back, and as Fiat Chrysler Automobiles tells it, it's the most venomous breed ever born. Before you get too excited, the 8.4-liter V10 produces 645 horsepower; five more than the standard Viper and five less than the supercharged Chevrolet Corvette Z06. It's unclear why Dodge didn't extract more from the huge engine, although we somehow imagine that certain people in Maranello, Italy had a say in the matter. Instead of blessing the ACR variant with bunches of extra output, Dodge instead turned to an aggressive aerodynamics package that it claims delivers nearly a ton of downforce at the Viper's maximum speed of 177 miles per hour. The total aero package includes an adjustable, twin-element, carbon-fiber rear wing, carbon-fiber diffuser, an extendable front splitter, and dive planes. Those big louvers on the hood? Yeah, they're removable, too. The "race-tuned" suspension uses coil-over Bilstein shocks that offer ten different settings and up to three inches of height adjustment. Kumho Ecsta V720 tires were built specifically for the Viper ACR, and come in 355/30 in back and 295/25 in front, with 19-inch wheels at all four corners. Along with the aero improvements, Dodge is claiming the Viper can pull a race-car-like 1.5Gs in higher-speed turns. Carbon-ceramic brakes with six-piston calipers add the stopping power that's greater or equal to the ACR's cornering performance. Dodge was also keen to reduce weight, taking some rather dramatic measures in the effort. The stereo has just three speakers, while the electric function was removed from the seats. Even the carpet has been replaced with a "lightweight" alternative. Finally, Dodge is offering up the innovative 1 of 1 customization it pioneered with the Viper GT earlier this year. That means that not only can you get the fastest Viper ever built, but it'll be entirely your own when you take delivery.

Dodge recalls 121,603 examples of Dart for loss of brake assist

Dodge will recall 121,603 worldwide examples of the 2013-2014 Dart with the 2.0- and 2.4-liter engines because of possible loss of power brake assistance. The company reports two minor injuries and seven accidents potentially related to this problem. The affected models have build dates before Jan. 24, 2014. There are 105,458 of these vehicles in the US; 11,996 in Canada; 3,705 in Mexico; and 444 outside of NAFTA. This campaign doesn't affect Darts with the 1.4-liter engine. These vehicles' brake-booster vacuum tube routing can potentially allow oil to access and eventually to degrade the brake booster diaphragm. If this happens, then the vehicles could lose braking assist. The brakes themselves would continue to work, but the driver would experience longer stopping distances. A pop or similar sound of a vacuum leak sometimes precedes the problem, according to the automaker. Dealers will inspect the components and replace the vacuum tube. If technicians find oil in the tube, they'll also swap out the vacuum pump, brake booster, and master cylinder. Affected owners will receive notice from the company within the next 60 days. Statement: Vacuum-tube Assembly December 3, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 105,458 compact sedans in the U.S. to inspect and replace vacuum-tube assemblies and certain other components, as required. Some of the affected vehicles may be subject to oil migration that could affect their brake systems' power-assist feature. Foundation brake function is unaffected. However, if this condition occurs, the driver may notice hard pedal-feel on brake application, and longer distances may be required to stop the vehicle in emergency situations. An FCA US investigation identified certain model-year 2013-14 vehicles equipped with 2.0-liter and 2.4-liter engines, may have brake-booster vacuum-tube routing that inadvertently allows oil to reach the brake booster diaphragm, if ever the vacuum-pump check valve fails. Oil may degrade the diaphragm and lead to a loss of brake-assist – a feature that helps reduce stopping distances. FCA US is aware of two minor injuries and seven accidents that are or may be related to this condition. The recall is limited to model-year 2013-14 Dodge Dart sedans produced before Jan. 24, 2014. It also affects an estimated 11,996 cars in Canada; 3,705 in Mexico and 444 outside the NAFTA region. Vehicles equipped with 1.4-liter engines are excluded.
