If you wondered what such a feat would look like from inside...

If you thought the Hennessey Venom GT was anything other than world-smashingly fast, you just haven't been paying attention.

Hennessey unveils its latest tune: an 800-hp Jeep Grand Cherokee SRT8.

If you think 270 mph in a convertible is a good idea, there's probably only one car that comes to mind: the upcoming Bugatti Veyron Grand Sport Super Sport.

In standard trim the 2012 Chevrolet Camaro ZL1, at least going on the official figures released thus far as the vehicle is still not on sale, is already shaping up to be a very capable muscle car. We’d go so far as to say that it’s even encroaching on supercar territory thanks to its...

There's no point mincing words here. The Hennessey V650 builds on the already brutally effective CTS-V Wagon with another 100 horsepower, an electronic exhaust dump, and more.
