Hennessey's Venom F5 Revolution Roadster is fastest ever open-top
American company's new £2.4 million convertible hypercar targets lap records as the lightest Venom F5 yet!
Hennessey has revealed what it claims to be the fastest convertible ever created: a roofless variant of the stripped-out, track-focussed 1817bhp Hennessey Venom F5 Revolution.
Called the Venom F5 Revolution Roadster, it takes the crown from the standard, road-going Venom F5 Roadster, which the firm says can achieve a top speed of over 300mph, as the world’s fastest open-top.
The limited-run $3 million (£2.4m) roofless Revolution track car – of which all 12 examples are already sold – arrives in the same year as the coupé track car, which itself took what made the Venom F5 the world’s most powerful combustion production car but stripped out further to increase performance.
The Revolution Roadster offers “unmatched visceral driving experience”, founder Jon Hennessey said, and like the $2.7m (£2.3m) coupé has been created to crush lap records.
As such, the 'Fury' 6.6-litre V8 returns – with reworked cooling like the coupé track car – mid-mounted in the same carbonfibre tub. Power is sent to the rear wheels using the same seven-speed automatic gearbox, but this has now been calibrated for competitive use.
With the Roadster, like its standard road-going namesake, the car received a host of changes to keep it as competitive as the coupé. These are focussed around more downforce than the coupé track car, which includes significantly larger front and rear splitters and dive planes on the front fascia.
Another example is that top, which comes in the form of a removable carbon fibre panel to keep it as light as possible. Weighing just 18kg, the panel is secured with four quick-release bolts and two high-strength latches to withstand the hypercar’s “staggering acceleration capabilities and aerodynamic forces at extreme speed”, the firm says. Inside, it is lined in Alcantara upholstery pointing to the track car’s luxury positioning.
“The new Venom F5 Revolution Roadster combines our track-focused hypercar with an open-top for an unmatched visceral driving experience,” said Jon Hennessey.
Hennessey also focused on stripping out the track-honed open-top, to make it, alongside its track sibling, the lightest Venom F5 variant yet. It tips the scales below the 1360kg road-going models, although the firm wouldn’t confirm by how much or what was changed to make it lighter.
As a result, the American firm, notable for its speed-centric approach to car design, promises “phenomenal acceleration”. The Revolution Roadster will most likely go beyond the road car's 2.6sec 0-62mph time and could even push further than its claimed 300mph top speed.
Straight-line speed isn’t the only target with the Revolution cars, however, with new aerodynamics fitted to send the car around tracks as quickly as possible. This is most visible in the adjustable full-width carbonfibre rear wing, which can deliver more than 363kg of downforce at 186mph and more than 635kg at 249mph.
Double-wishbone suspension returns but now with more aggressive alignment settings and adjustable dampers.
Stopping power comes in the form of carbon-ceramic brakes – fitted as standard – that feature multi-piston callipers.
Inside, the same luxurious interior can be found, now with the addition of a real-time digital track telemetry system capable of measuring data such as lap times, splits, and cornering g-forces.
