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 2018 Dodge Demon sounds like nothing else on the road

The Dodge Demon seems to have a torque problem, if making too much to easily contain can be considered a problem. In order to keep all that twist under control, the Demon has a new torque reserve launch system that works all sorts of engineering black magic to build boost without overloading the rear tires and brakes. That system, combined with the sticky Nittos and the fancy new suspension, should lead to some pretty spectacular 60-foot and 1/4-mile times. The way the system works is relatively straightforward. A bypass valve on the supercharger closes, "prefilling" the blower. In order to balance revs and torque, the computer can adjust fuel flow and spark on individual cylinders. The torque reserve kicks in when Launch Mode is initiated and the engine is turning at least 1,000 rpm. The goal is to reach peak boost quicker while efficiently putting down power. The side effect is a distinct exhaust note, which Dodge admits may make it seem like the Demon is broken. That seems to be the root of the "If you know, you know" tagline that the automaker has been using since the first teaser. Those interested can even download a ringtone, which might make it seem like you have a blown-out speaker on your phone. You can get a brief taste in the latest teaser video. In addition to the new info on the Launch Mode, Dodge released a couple of new teaser images. We briefly glimpsed one of these last week. It's a shot of the Demon's performance pages. The number 757 has appeared before, and all the talk of torque leads us to conclude that this is the Demon's torque output. The number 815 was seen in a separate teaser (shown below), which we feel may be the horsepower rating. If those numbers are correct, that would mean an increase of 108 horsepower and 107 lb-ft of torque, totally reasonable numbers given all the Demon's modifications. The license plate photo is another equation or code. This one, 3.9+221=405, is just as cryptic as the others.

Stellantis axed the SRT engineer team, but performance isn't going away

Stellantis has broken up the Street & Racing Technology (SRT) engineering team that created over a dozen high-performance vehicles, including the Dodge Charger Hellcat, but the situation isn't as dire as it sounds. The newly-formed company assigned SRT's former engineers to different positions, where they'll continue to make hot rods. "All of the core elements of the SRT performance engineering team have been integrated into our company's global engineering organization," a spokeswoman told enthusiast website Mopar Insiders. She added that integrating SRT's personnel into other brands in the Stellantis portfolio will ensure that the lessons learned from decades of peddling speed will permeate other products. Previously, SRT operated with a high degree of independence. Don't get too excited. Her statement does not necessarily mean that Citroen will begin building cars powered by the Hellcat engine, though a C3 Chat D'enfer sounds absolutely epic. Technology transfer will likely be limited to fields like aerodynamics and thermal management, and the design department might learn a couple of neat new tricks. Dodge will still move forward with the development of its next SRT-branded cars; the decision to dissolve the SRT team will not affect future models, according to the spokeswoman. Whether they'll be powered by a V8 is up in the air, because company boss Tim Kuniskis warned that regulations are killing the eight-cylinder engine. Similarly, Jeep will continue designing high-performance models, like the Grand Cherokee Trackhawk. What changes is that the model will be developed and designed by a group of engineers and designers from Jeep, not from SRT. SRT is dead, but performance isn't going away. SRT's demise nonetheless marks the end of an era for Chrysler. The division traces its roots to 1989, when some of the company's brightest minds were brought together to develop the first-generation Dodge Viper. It merged with Team Prowler to form the Specialty Vehicle Engineering (SVE) group, which was renamed Performance Vehicle Operations (PVO) in 2002 and finally dubbed SRT in 2004. SRT has operated as the carmaker's in-house tuner since, its resume includes a diverse selection of cars ranging from the Neon SRT-4 to the 1500 TRX, and it was promoted to a standalone brand led by designer Ralph Gilles in 2011. Fiat-Chrysler Automobiles (FCA) axed the SRT brand in 2014 but kept the name and the development team. Related video:
