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.

Viper owners raising money to retake the Nurburgring lap record

Nurburgring lap times – unofficial as they may be – are the locker room comparison contest of the automotive world. For several years, the lap record of 7:12:13 was held by a 2011 Dodge Viper ACR. The Viper and America were the rulers of the roost until the usurper, the Porsche 918, came in a stole the crown. The death knell is ringing for the Viper, and a group of owners are raising money to send the car to the 'Ring for one last chance at glory. The current Dodge Viper ACR is an astonishingly capable car. All of the flaws that make it miserable to live with everyday - stiff suspension, obnoxious exhaust, speed-bump-gouging splitter - make it one of the most formidable road-legal track machines ever created. Unfortunately, that single-purpose nature turned off a lot of customers, and slow sales have led to the end of Viper production. The Viper holds lap records on more than a dozen of tracks, but, like a driver winning the Indianapolis 500, only one belt notch truly matters. The ViperExchange is willing to supply two ACRs and two drivers well versed in the Nurburgring in order to retake the record. The problem with attempting to set the record is mostly down to logistics. According to the GoFundMe page, the total cost to send the cars, pay for the track, the supplies, and operating expenses is about $150,000 and $200,000. The group says this is entirely a volunteer effort and are asking for donations to fund the Viper's return. Those wishing to help replant the stars and stripes and fill the forests of Germany with the truck-like roar of an odd-firing V10 can donate online. If they fall short, donations will be returned.

Chrysler almost smothered the Hellcat before it lived

Chrysler's 6.2-liter supercharged Hellcat V8 was an absolute sensation from the very moment it was announced, and honestly, how could it not have been? Packing 707 horsepower and 650 pound-feet of torque, its numbers immediately put every other production muscle car (and many supercars) to shame. Plus, we soon learned that would be wrapped in a package retailing for around $60,000 - a pittance compared to other vehicles offering similar grunt. However, the Hellcat almost never got the chance to rumble under the hood of the Challenger and Charger.
The Hellcat was initially proposed back in 2011, back when Fiat was deciding its future strategy for Chrysler Group, according to Automotive News. At the time, the company was just emerging from its bankruptcy doldrums, and an ultra-high-performance V8 wasn't exactly a must-have item. The program didn't move forward. However, SRT engineers kept fighting, according to AN, and four months later, they received the green light to pull the project off the shelf and continue developing the Hellcat. The muscle car world is certainly better for that decision.
The work of those engineers focused on taking Chrysler's standard 6.2-liter V8 and making it reliably handle all of the extra power from the supercharger. "It came down to micron levels of changes in the crank to be able to withstand the pressures of the engine," said Chris Cowland, director of advanced and SRT powertrain, to Automotive News. The changes amounted to switching out about 91 percent of the parts to make the Hellcat, including some quite minuscule alterations. For example, the washer holding the supercharger pulley is embedded with industrial diamonds to keep it from slipping.
