No turbos, no hybrid, no screens and a six-speed manual. Jay gets an early look at the Hennessey Blackbird. Jay first met John Hennessey in 1993, back when John was a Texas hot rodder bolting more speed onto Vipers. Since then he's built the Venom F5, which makes over 2,000 horsepower. For his next car he's gone the other way. The Blackbird runs a naturally aspirated 6.2-liter dual overhead cam V8, developed with Ilmor, that's targeted at 800 to 850 hp and revs past 9,000 rpm. It drives the rear wheels through a gated six-speed manual. Hennessey says it will be the most powerful naturally aspirated V8 ever put in a road-going production car.
