"Currently our CFD testing and our engineers tell us we need about 1,520 bhp to break 300," Hennessey told Motor Authority. "I’d like to run 500 kph. Which is 311 and change."
The challenge is finding a place to reach these speeds. The runway Kennedy Space Center is only long enough to hit around 280 mph in Hennessey's estimation. He figures the company would need to shutdown a long stretch of highway similar to Koenigsegg's use of an empty Nevada road from the Agera RS' 277.9 mile-per-hour record run.
A record attempt is still at least a year away. Hennessey will begin testing a Venom F5 prototype in 2019, and high-speed testing won't begin until late in the year.
During Monterey Car Week, Hennessey revealed the Venom F5's amazing engine. It's a twin-turbo 7.6-litre V8 that makes 1,600 bhp and 1,300 pound-feet of torque. The block is billet aluminium with steel cylinder sleeves. The engine will sit in a Hennessey-designed chassis, and a carbon fibre body will wrap around it. The company's projections put the vehicle's weight below 1,360 kilograms and give the exterior a drag coefficient of 0.33.
Hennessey will build only 24 units of the Venom F5 at a price of $1.6 million (approx. £1.22 using current exchange rate) each. Twelve of them are for the United States, and the rest are available to international customers. All of the examples for America have reservations, but there are still seven to order among folks in the rest of the world, according to Motor Authority.
