Zenvo Automotive A/S (‘Zenvo’), the Danish high-performance automotive company, has today unveiled its new model at the Geneva International Motor Show. The Zenvo TSR-S is positioned between the company’s TS1 GT car and its racetrack-bred sibling, the TSR, combining phenomenal on-road capabilities with ultimate exclusivity.
The TSR-S is a street legal version of the TSR – hence the ’S’ in the model name. Featuring an innovative and striking new active multi-axis Centripetal Wing and an in-house developed twin supercharged V8 engine, production of the TSR-S is now underway within Zenvo’s limited production of just five cars a year.
Setting the car apart from its rivals, the TSR-S incorporates manually-adjustable performance settings including a variable power output. In addition, the unique dual gearbox set-up can switch between a standard road gearbox configuration and a brutal mechanical direct power-shift race set-up that delivers a genuine race car experience on the track.
Troels Vollertsen, Chief Technical Officer and Founder of the company, explains:
“In developing the TSR-S, the utmost dedication and ambition of our team has driven us to achieve unprecedented levels of aerodynamic engineering capability for a road-going car. By converging the individual performance characteristics of the exceptional TS1 GT hypercar with the savage TSR track car we have created the ultimate Zenvo. The TSR-S is a once-in-a-generation car with cutting-edge technologies that will define new boundaries in automotive engineering, and will rightfully place it in the very highest echelons of the hypercar world.”
The ground-breaking rear wing has two rotational axes enabling it to function both as an air break and a cornering stabilizer. When the TSR-S corners, the wing rotates relative to the car’s longitudinal axis. This generates an inward force together with the conventional downforce, boosting inner tyre grip and cornering stability.
Vollertsen explains: “The Centripetal Wing is an exceptional development that allows for increased grip and higher cornering speed. Whereas most supercars only achieve optimum downforce in cornering at a certain speed, the multi-rotational function of the wing distributes downforce in an innovative way to deliver the optimum amount of cornering grip at any speed. Whilst lifting to boost downforce, the wing also tilts while cornering – for example, lifting the left side of the wing when cornering left and vice versa, to propel the car to the inside of the corner, ensuring exceptional stability and grip.”
The name ‘Centripetal’ directly refers to the centripetal force also known as ‘center seeking’ force. When in an absolutely horizontal position, a conventional rear wing generates a downforce perpendicular to the horizontal position of the wing: absolute vertical. When the centripetal wing tilts away from the absolute horizontal, the downforce stays perpendicular to the plane of the wing thereby generating a centripetal force. This centripetal force reduces the tendency of the rear end to break away – a trait that is inherent for a mid-engine car. Furthermore, the high pivot point of the wing allows it to act as an additional rear anti-roll bar. This provides additional grip to the inner wheel, reducing the chance of a loss of traction at the rear, and also ensuring increased downforce on the inner wheel. The wing also functions as air brake when fully-rotated in an upright position.
