It's a good thing Hennessey is headquartered in Texas. With 750 horsepower, the Hennessey HPE750 ZL1 Camaro would seem like a waste anywhere else, outside of Germany that is. That's because Texas has SH 310, which has an 85 mph speed limit and is billed as "the fastest highway in America."

During a recent Texas State Police-sanctioned test run, Hennessey's custom ZL1 reached a top speed of 203.9 mph. Hennessey says it was helping to test the TxTag electronic toll collection system. The diabolical sound of the ZL1's supercharged V-8 screaming down the highway was all in the name of science, apparently.

Like all of Hennessey's other monsters, this ZL1 had been thoroughly tinkered with, including upgrades to everything from the cylinder heads to the fuel system. The HPE750 ZL1 isn't even the most powerful Hennessey Camaro. The HPE1000 ZL1 produces a staggering 1,026 horsepower. That probably would have punched a hole in the spacetime continuum.

Hennessey pulled a similar stunt last year with its VR1200 twin-turbo Cadillac CTS-V Coupe. The incredible 1,226-horsepower Cadillac reached a top speed of 220.5 mph, making it the fastest CTS-V in the world. Not that there was much competition.

Hopefully the Texas State Police will need to conduct more tests of this nature on TxTag. Maybe next year Hennessey will bring a Venom GT.
