Hennessey has published a press release providing extensive details about the Venom F5.
The Venom F5 is gunning for the top speed world record with an estimated 290 mph (466.71 km/h) coming from an evolution of the 270 mph Venom GT. It will feature a more aerodynamic body which will reduce the drag coefficient from 0.44 to below 0.40 while generating a high amount of downforce thanks to a rear diffuser, retractable rear wing and a specifically designed underbody.
At its heart will be an uprated variant of the twin-turbo V8 7.0-liter engine which in the Venom GT delivers 1,244 bhp (928 kW). By increasing the size of the turbochargers and upgrading the intercooler and fuel system, Hennessey's engineers will be able to squeeze more than 1,400 bhp (1,044 kW) wrapped around in a body which won't exceed 1,300 kg (2,866 lbs) thanks to extensive use of carbon fiber and aluminum.
The Texas-based tuner / specialty marque estimates the Venom F5 will be faster than the Lotus Exige-based Venom GT in the 0-186 mph (0-300 km/h) sprint so expect the run to take less than 13.63 seconds while the 0-200 mph (0-322 km/h) journey will be done in less than 14.51 seconds.
The Venom F5 will be offered with a newly developed single-clutch paddle-shift gearbox which will be lighter than the regular H-pattern manual gearbox and will also enable the vehicle to accelerate quicker. Moreover, a GPS-based stability/traction control system "will help to channel the F5's immense power and provide an increased margin of safety, whether on a racetrack or back road."
A full reveal is scheduled for 2015 but deliveries will kick off towards the end of 2016. A minimum of 30 units will be built and production will start after Hennessey will roll out the final Venom GT. 16 cars have been built so far out of a total production of 29 units, each priced at 1.2M USD. Needless to say, the Venom F5 will be more expensive to justify the upgrades.
