Dodge Viper ACR reportedly green lit [w/video]

The Dodge Viper might be getting a little more venomous in the near future thanks to a return of the performance-honed ACR trim. According to an anonymous source leaking the info to Allpar, the version would go into production in July as a 2016 model year vehicle. FCA US showed a concept for a future ACR (pictured above) at the 2014 SEMA Show that sported carbon fiber parts for the front splitter and dive planes, plus a picnic-table-sized rear wing. The body also received ducts at the rear to shoot cool air to the differential. A set of 15.4-inch carbon-ceramic brake rotors also brought things to a halt in a hurry. The company promised all the aero pieces were sculpted in the wind tunnel to give the coupe even more downforce. To shed weight, engineers chucked the radio, speakers, carpet and sound deadening out of the interior, and they replaced many bits with even more carbon fiber. All of the tweaks are necessary because the ACR moniker carries serious cachet for the Viper at the track, especially at the Nurburgring. One reportedly did a 7:22 lap around the 'Ring in 2008, and another improved that further to 7:12 in 2011. Autoblog reached out to FCA US for comment about the possibility for the hotter Viper, but the company wasn't willing to comment about any possible, future projects. Related Video:

VLF Force 1 V10 is a rebodied Viper priced like a Lamborghini

It would appear that Henrik Fisker is done with hybrids. His latest project, called the Force 1, packs an oversized V10 engine with no electric assist in sight and all the environmental credentials of a herd of flatulent cattle. Alongside the Karma-based, Corvette-powered Destino, the Force 1 is the second product from VLF Automotive. Fisker has taken partnership in the new firm as chief designer alongside chairman Bob Lutz and CEO Gilbert Villarreal. The company isn't saying explicitly what the Force 1 is based on, but it doesn't take a CSI team to trace its roots back to the Dodge Viper. Never mind that it's being built in Auburn Hills – the same Detroit suburb where Chrysler is headquartered – or that it was jointly developed by Fisker and professional Viper racer and dealer Ben Keating. It also happens to be powered by an 8.4-liter V10, and there aren't many of those kicking around the industry. Instead of the Viper's 645 horsepower and 600 pound-feet of torque, the Force 1's ten-cylinder engine is optimized to deliver 745 hp and 638 lb-ft. That, according to VLF, is enough to send the coupe rocketing to 60 in 3.0 seconds flat, covering the quarter-mile in under 11 seconds on its way to a top speed of 218 miles per hour. The power is transmitted to the Pirelli PZero rubber through a six-speed manual, but VLF says it will fit it with an automatic at the customer's request. Around that massive engine and two-seat cockpit, Fisker designed a new shape that, for better or for worse, looks way more aggressive than the Viper's. The Force 1's proportions are tellingly super-snake, but the curves are replaced by some very angry-looking angles and vents. Its head- and taillights are ultra thin, and the deep-dish, split-four-spoke wheels seem to visually split the difference between the three-spoke wheels on the original Viper and the five-spoke alloys it wears today. If you doubted the Force 1's origins before, the interior ought to give it away, with its wide tunnel and familiar surfaces. Only VLF has refinished it in leather, suede, and Alcantara, all diamond stitched with contrasting thread to help position this as a more luxurious prospect than the Dodge. It even fit between the seatbacks place for two champagne bottles that we hope nobody would consider consuming before trying to handle that much power. Of course, none of this will come cheap.

Watch Atieva's electric van outrun a BMW i8 and Dodge Viper

A little while back, automotive startup Atieva drag raced its electric van, called Edna, against a Tesla Model S and a Ferrari California in order to compare its performance against known and revered mechanical athletes. Again, the Silicon Valley-based company is putting its prototype up against electrified and conventionally powered performance vehicles on the drag strip. Last time around, Edna, the Mercedes-Benz Vito van equipped with a 900-horsepower, all-wheel-drive powertrain, bested both of its foes. In that showcase, Edna was hitting 60 mph in a little over three seconds. Comparatively, BMW lists the i8's 0-60 time at 4.2 seconds, though Road & Track clocked it at 3.8 seconds, with a quarter-mile time of 12.3 seconds. The Viper does 0-60 in 3.4 seconds. Before you even watch the video above, you can imagine how it will end, as the retuned Atieva Edna rips 0-60 mph in 2.94 seconds. Atieva clocked the quarter mile at 11.3 seconds at 117 mph. It's worth noting that driver skill can have a lot to do with a car's straight-line performance. We've witnessed Viper's elapsing the quarter mile in well under 12 seconds, which means it should be quicker in this test than the i8, if not the Edna. Still, the performance showcased in the video is exceptional. To improve Edna's stats, Atieva says it has used testing data to fine tune its AC induction motors at higher speeds once it got low-speed performance locked in. After testing in the hot California sun, including the race you see above, Atieva drove Edna 90 miles home with range to spare. As for production plans, Atieva will put this powertrain into a sedan slated for sale in 2018. In the meantime, the company will keep testing and tuning its working prototype, and has even invited the public to put their cars up against Edna in future sessions.
