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.

The TSR-S has been completely redesigned and reengineered for optimum aerodynamic performance. This, combined with a further improved active rear differential and an advanced traction control system, helps the TSR-S to deliver an unrivalled performance on the road, for a genuinely unique hypercar experience.

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."

Since its formation in 2007, Zenvo has established a reputation for engineering excellence and innovation.

Building on this foundation, advanced aerodynamic analysis and implementation of advanced airflow management on the TSR-S helps the car generate more than three times as much downforce as the TS1 GT. Central to this is the dramatic Zenvo Centripetal Wing.

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.

The aerodynamic development of the Zenvo TSR-S was focused on providing unprecedented driving dynamics. The centripetal rear wing is only one contributor to the comprehensive new aerodynamic package. Other unique and innovative new features collaborate to improve stability, cornering and braking.

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 stabilise the air around the front wheels 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 LMP1-inspired air scoop, new diffuser and the proprietary active rear wing. The diffuser is optimised to extract air from the underbody and decrease the rear tyre wake for increased stability.

Kasper Berthu Damkjar, Senior Fluid Mechanics Specialist and Aerotak ApS founder, participated in the development of the TSR-S aerodynamics. "The wing concept is focused on delivering high downforce while increasing the tyre load on the inboard tyres when cornering," says Damkjar. "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 wing concept is able to maintain the high downforce and generate a large inwards directed force. When the wing is tilted, downforce is only decreased by 3%, while an inward directed force of 30% of the wing downforce is generated."
