If you thought the Hennessey Venom GT was anything other than world-smashingly fast, you just haven't been paying attention. Now, however, it holds the title of world's quickest--to 186 mph, at least.

The specific details of the feat, accomplished today, will be forthcoming in an episode of Drive two weeks from now, but we do know that the Guinness Book of World Records was on hand to certify the blazing run along an airstrip in Texas.

It took the Venom GT just 13.63 seconds to hit 300 kilometers per hour, or 186.411 mph.

No matter how you slice it, that's quick.

But, get this: the mental mechanical masterminds at Hennessey are planning an even nuttier version for 2014, with 1,500 horsepower on tap.
