Helical has built two bespoke prototype supercars inspired by the TVR Cerbera Speed 12. The Mk1 GT Racecar is naturally-aspirated, the Mk2 GT Roadcar is turbocharged. The Speed 12 Turbo comes under TR-Supercars brand (previously known as TBR Speed 12 Turbo) and features a twin-turbo 6.0-litre dry sump V12 engine developing 1012bhp, resulting in a 0-60mph time of 2.9 seconds and a top speed of over 218mph.
Helical’s venture into supercar manufacture has provided the opportunity to develop and test new technologies such as carbon fibre composites, acoustic electronic exhaust valves, titanium exhaust system, sound enhancement technologies and other blue sky R&D projects.
The Supercars also act as dynamic test rigs to test the product design iterations in real-life scenarios, where the driving dynamics factor is a valued addition over standard test equipment in the laboratories.
Modern turbocharged engines have lost the desired sound quality that customers yearn for and Helical is striving to develop a natural pleasing normally aspirated V-engine sound from today’s modern turbocharged engines.
