Dodge Viper ACR still can't quite capture Nurburgring record

Dodge Viper production ended just a few weeks ago. So in an effort to go out with a bang, a crowdfunded effort sent a pair of new Viper ACRs to the Nurburgring in order to reclaim the production-car lap record. Despite its best efforts, the team failed to top the Lamborghini Huracan Performante's time of 6 minutes and 52 seconds. The Viper's best lap was 7 minutes and 3.45 seconds, leaving a seemingly insurmountable gap between it and the Lamborghini. This past week, the Vipers went out again. Unfortunately the new time of 7:3.23 only shaved a few tenths. Road & Track reports that the hot weather played a major factor into the car's performance. August is hot in Germany, and the northern part of the track had a recorded temperature of 111 degrees. This was killing tires and therefore grip. While Kumho has been kind enough to supply the team with tires, an endless supply of rubber doesn't help if they keep getting cooked. In two hours, the team managed just two hot laps, killing 16 tires in the process. It's not over. A return trip is in the works. The team believes it can slide under the 7 minute mark. Still, it looks like it's going to take some really ideal conditions to make it work. Either way, the Viper ACR is and will remain one of the fastest production cars ever built and something of the likes we'll never see again. Related Video: This content is hosted by a third party.

Chrysler set to make $266M-investment into 8-speed transmission production

Chrysler will shortly make a significant $266-million investment into its Kokomo, IN transmission factory in a bid to expand production of its eight-speed automatic transmissions. The gearboxes, which are built under license from Germany's ZF Friedrichshafen, have been well received by customers and critics, and according to an SEC filing obtained by Automotive News, the transmissions will eventually find their way to all of Chrysler's rear-drive offerings (Viper and heavy-duty Ram models, aside). According to AN, a Chrysler spokesman says the investment has not been confirmed, but once it is, it'll mark the company's latest in a growing line of investments at the facility. Chrysler has poured $1.5 billion into Kokomo since 2009.

The Dodge Demon gets a Drag Mode and a lesson in Newtonian physics

It's Thursday morning, which means we have more news on the upcoming Dodge Demon, the pumped-up Challenger Hellcat variant that's looking to cause mayhem at a drag strip near you. This week's video, "Third Law," shows the Demon's revised suspension in action and displays another one of SRT's cryptic messages. Dodge claims that the 6.2-liter supercharged Hemi V8 in the Hellcat twins is compromised because it's fitted to a car that needs to be comfortable on the street in addition to a performer on the drag strip. Not so with the Demon, as Dodge says the car is "designed to be highly competent in all drive modes and configurations," including the all-new Drag Mode. Dodge says details about the new mode will trickle out over the next few weeks, but all the info this week focused on suspension. The "Third Law" in this week's title refers to Isaac Newton and motion: "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body." We're not sure what Newton would have thought seeing the sidewall wrinkling Nitto NT05R drag radials in action, but he'd probably have a reaction of some sort himself. An ideal suspension setup for the drag strip makes for a poor setup on the road. As Dodge puts it, the "old school" way to set up a drag car was to "get the quickest reacting springs upfront, the softest rebound front shocks that wouldn't restrict the springs' reaction, remove any restrictions (sway bar) and increase the compression of the rear shocks." This would give a car great front to rear weight transfer but made for very poor lateral direction control, meaning minor corrections were difficult. The Demon's Drag Mode will use electronics to give the car the best combination of launch and lateral stability. Dodge listed some of the parts to help aid in this goal. They also gave us a few equations that we can't make sense of. Let us know if you have any clues.
