The halo is coming to sportscar racing. Revolution Race Cars have unveiled a new ‘double-halo’ for its A-One sports prototype racer.
The ‘double halo’, inspired by the head protection structure mandated in Formula One at the beginning of 2018, is the first ‘halo’ type structure to be developed for a two-seater (open-top) sports prototype.
This new structure bolts to Revolution’s advanced carbon-fibre monocoque chassis. Both the ‘double-halo’ and the chassis are compliant with the latest FIA Article 277 safety standards. The ‘double-halo’ is manufactured from 50.8mm diameter ROPT510 seamless tubing, exceeding the FIA minimum diameter requirement by over 12%.
“We designed the A-One to give more elbow room than other prototype racing cars, making it easy to operate both solo and with a passenger aboard,” said Phil Abbott, Managing Director, Revolution. “By introducing the ‘double-halo’ we are giving drivers and their instructors or corporate guests the same level of safety they would expect in a world championship type race car.”
The unique ‘double-halo’ gives the Revolution similarly high safety standards to closed-cockpit Le Mans cars but without the complexity of accessibility, door structures and cooling systems that can add unwanted weight.
The ‘double-halo’ is an option for drivers in the Revolution UK Trophy, which runs within the Sports Prototype Cup. The car has only a 2kg net weight increase with the ‘double-halo’.
The device has been tested by several drivers, including Sir Chris Hoy (featured). The decorated British Olympian, who has experience of racing LMP2 cars at Le Mans said: “The double-halo gives a real sense of security and still has great visibility. I didn’t even notice it once up to speed.
“The Revolution has a smooth power delivery and is very predictable to drive. It’s really well engineered and finished. The quality is apparent in the design and build.”
The opening rounds of the 2020 Revolution Trophy and Sports Prototype Cup were scheduled for May 23rd at Silverstone but the event has been postponed until at least June 30th due to the MSA’s decision to pause motorsport.
