At the Geneva International Motor Show 2018 we unveiled the highly anticipated new model TSR-S: a crossover between the TS1 GT car and its racetrack-bred sibling, the TSR. The TSR-S is a street legal version of the TSR – hence the ’S’ in the model name.

The aerodynamic development of the TSR-S was focused on providing unprecedented driving dynamics. The unique and innovative new features all collaborate to improve stability, cornering and breaking.

Exclusively available on the TSR-S, its Centripetal Wing revolutionises stability and high-speed cornering.

The TSR-S delivers 1177bhp at 8,500 RPM in a package over 100kg lighter than the TS1 GT. 0-100 km/h (62 mph) in 2.8 seconds, 0-200 km/h (124 mph) in just 6.8 seconds.

Advanced aerodynamic design

The new front splitter is designed to improve front to rear downforce distribution by generating front downforce and directing air to the underbody. The front bumper is updated together with the front wheel housing outlets. Together they decrease the front wheel wake and direct air to the intercoolers. At the same time the front wheel housing outlets extracts air from the front underbody, improving downforce and decreasing drag.

The rear body of the car features major updates with an air scoop, new diffuser that is optimized to extract air from the underbody and decrease the rear tyre wake.

The ground-breaking Centripetal Wing has two rotation degrees of freedom enabling it function as an air brake and cornering stabilizer. When the TSR-S corners the wing rotates around the car’s longitudinal direction generating an inward force together with the conventional downforce. This boosts inner tyre grip and cornering stability.

The wing concept is focused on delivering high downforce while increasing the tyre load on the inboard tyres when cornering. Conventional movable wing and flap designs, focused on inboard tyre load, function by a penalty concept where downforce is increased on the inboard section of the cornering car but not on the outboard section. The TSR-S Centripetal Wing concept is able to maintain the high downforce and generate a large inwards directed force.
