Video: Darrell Waltrip laps Bathurst with V8 Supercar driver Jason Bright

One of the most entertaining things to come out of the Bathurst 1000 last weekend in Australia--besides Garth Tander and Nick Percat taking the checkered flag--was ex-NASCAR driver and commentator Darrel Waltrip going for a wild hot lap with V8 Supercar driver Jason Bright. After taking the first turn at speed in the 650-hp Holden Commodore, Waltrip yells, “Impossible!” The video gets even more entertaining around the Esses and the Dipper, two succeeding corners. The clip is full of repeatable one-liners from Waltrip including, “I lost my lunch, and I didn't even have lunch.” He calls the track on Mount Panorama a geological oddity.

2013 SRT Viper packs devilish details

The 640-hp V10, the curvy fenders, heck, even the carbon treatments—there are enough spotlight features on the 2013 SRT Viper to outfit two or three sports cars of lesser pedigree. While the potent engine and the striking design are clearly the signature elements of SRT's macho machine, there are a few subtle design cues lurking inside for sharp-eyed enthusiasts. Let's call them Easter eggs, and they're intricate yet intriguing.

Porsche nearing 900 orders for its 918 Spyder hybrid concept

When Porsche AG showed the 918 Spyder at the Geneva show in March, we said it was a car to “make anyone a believer in hybrid supercar tech.” Well, maybe not anyone, but Porsche now says it has almost 900 potential buyers for the two-seater hybrid prototype as the German automaker gets closer to approving production. Porsche development chief Wolfgang Duerheimer said he is confident the company will soon reach the threshold of 1,000 orders, which is how many the company needs to “make a sound business case.” The 918 has 680 hp and, according to Porsche, will get 78 mpg and run from 0 to 60 mph in 3 seconds. Porsche said it wants to double its overall vehicle sales to 150,000 in the next five years or so.
