When news broke out that Gray Design was branching out to fine world of automotive awesomeness, very few foresaw that these guys were far more serious than many people thought.

We’ve already touched on two of the models - the Gold Rush and the Magnate - so naturally, the third and final piece to this puzzle is arguably the most radical of the bunch.

Called the Sigma, this car certainly looks the part of what you’d expect from a supercar. It’s body is built from carbon fiber, which is saying a lot considering that the material being used isn’t exactly the kind that you can find anywhere. Zeus Twelve emphasized building the a lightweight machine for the Sigma and the car’s overall design certainly speaks to its supercar appeal.

Here’s where it takes a turn to the ironic: despite looking the part of a supercar, the Sigma is the least powerful of the bunch, featuring "only" a 2.0-liter Caterham Duratec Straight 4 engine that produces 335 horsepower at 7,500 rpm, good enough to hit a top speed of 180 mph.

We don’t know the reasoning behind this, but it’s something that’s worth keeping tabs on.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read More
