'American Nitro' is back!

"Seventies drag-race mayhem is back!" bills "American Nitro," a schlocky drive-in exploitation film whose only quote of praise, from a dog-eared period issue of "Car Craft," reads, simply, "SPECTACULAR CRASHES!" Director Bill Kimberlin says that he made "American Nitro" in 1979 as a response to Tom Wolfe's influential 1965 essay, "The Kandy-Kolored Tangerine-Flake Streamline Baby." "I was just getting out of high school in a small town in Northern California when Wolfe's book came out," he said. "Nitro came about as my response to the car culture I was exposed to in the small valley town of Boonville, Calif. Instead of 'American Graffiti,' I made 'American Nitro.'" A fitting comparison, in fact, considering Kimberlin later worked for George Lucas at ILM, starting with" Return of the Jedi." Now the movie is being released on DVD for the first time -- beware of bootlegs, warns the website -- and digitally remastered, while retaining the explosive charm and goofy narration of the 1979 original.

Aston Martin V12 Zagato – 49 bite the dust

The Aston Martin V12 Zagato was going to have up to a 150 production run, but Aston Martin now say they will build just 101 cars. The Aston Martin V12 Zagato is a great creation with OTT styling courtesy of Zagato. But, when all’s said and done, it’s just a V12 Vantage in pretty clothes with a few tweaks, yet it costs three times as much – a slightly eye-watering £330k.

Audi A1 Quattro models ‘on the way’

Audi has confirmed it is testing four-wheel drive Quattro versions of the A1 – indicating an imminent expansion of Audi’s supermini range. Although showcased as this one-off at a Quattro publicity event in Montreal, Canada, to celebrate 30 years of the all-corner drive system, Ingolstadt acknowledged at last autumn’s 2010 Paris motor show that Quattro versions of the A1 were in the pipeline. The production A1 Quattro will use the Haldex differential to split drive to both axles; it’s a similar technology to that found in A3 and TT Quattros, as opposed to the mechanical Torsen diff found in larger Quattro models.
