"If at first you don't succeed, just add more horsepower and rpm and try again," Hennessey said in the company's announcement. Rather than the 717 horsepower and 632 pound-feet of torque from the supercharged 5.0-liter V8 in the HPE700, the HPE750 ratchets the same powertrain up to an even more potent 774 hp and 648 lb-ft.
In a real show of confidence, the Hennessey team brought along Jay Leno when it returned to the Continental Tire Proving Grounds in Uvalde, TX, to set a new top speed with the HPE750. The upgrades to the Mustang definitely paid off because the pony car reached a GPS-verified 207.9 miles per hour down the straight. The run will eventually appear on a segment on the upcoming Jay Leno's Garage TV show that will air CNBC.
Prices for the HPE750 start at $59,500 USD, including the base 2015 Mustang GT, but building an exact replica of this one would cost $69,374, according to Hennessey. In addition to the huge top speed, the company claims that the coupe can reach 60 mph in 3.4 seconds and cover the quarter mile in 10.9 seconds.

Uvalde, Texas—On Wednesday, May 27, 2015, professional driver, Brian Smith, drove the Hennessey HPE750 Supercharged Mustang to a top speed of 207.9 mph. In the process, Hennessey's potent pony car became the first 2015 Mustang to break the 200 mph mark. Jay Leno was on hand to witness the record speed while filming an upcoming episode of Jay Leno's Garage, which will air on CNBC later this year.
The run was made on the 8.5 mile high speed oval at the Continental Tire Proving Grounds located in Uvalde, Texas – the same test track where John Hennessey test drove the company's HPE700 Mustang to a top speed of 195 mph back in February of this year. During both tests, speeds were validated with Racelogic's VBox 3i GPS data logging system.
"If at first you don't succeed, just add more horsepower and rpm and try again," said company founder and president, John Hennessey. "It's pretty cool to be able to offer an American muscle car that delivers supercar performance for under $70,000.
"I have a lot of seat time in the 2015 Mustang GT, since the Ford Performance Racing School has a fleet of them that we use for high-performance driver training," said Brian Smith, GM of Utah's Miller Motorsports Park and instructor at Ford Performance Racing School. "The Mustang GT is a fast, good-handling car right from the factory, but the Hennessey Mustang takes it to a completely new level. The Hennessey high-performance upgrades transform a very good GT car into a legitimate supercar."
