Danish automotive brand Zenvo has just added a new, third model to its twin-supercharged car line-up.
Unveiled this week at the Geneva motor show, the new TSR-S is being positioned between the company’s TS1 GT and its racetrack-bred sibling, the TSR.
Effectively a street legal version of the TSR – hence the ’S’ in the model name – the new car has not only been redesigned and reengineered for improved aerodynamics, but it also uses a more powerful version of Zenvo’s in-house developed twin supercharged 5.8-litre V8.
Mated to a paddle shift 7-speed gearbox, the engine is now claimed to produce 1177 bhp at 8,500 rpm and more than 811 lb-ft of torque, which enables the car to do 0-62 mph in just 2.8 seconds and 0-124 mph in 6.8 seconds. Top speed is limited to 202 mph.
The TSR-S is also claimed to generate more than three times as much downforce as the TS1 GT. Central to this is a new active multi-axis rear wing system. Dubbed the “Centripetal Wing”, it has two rotational axes enabling it to function both as an air break and a cornering stabiliser.
“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,” explains Troels Vollertsen, Zenvo’s founder and chief technical officer.
“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,” adds Kasper Berthu Damkjær, a senior fluid mechanics specialist who participated in the development of the TSR-S’s aerodynamics. “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.”
In addition to the new active rear wing, the back of the TSR-S has also been updated with an LMP1-inspired air scoop and new diffuser.
Aerodynamic-inspired changes can also been seen at the front of the car, with a new splitter, an updated front bumper and revised front wheel housing outlets. Together, all of these elements are claimed to increase downforce and decrease drag.
On the inside, in its top-end configuration, the car has no sound system or speakers, no satellite navigation, no air conditioning, no airbags, and mechanically-operated carbon seats.
Tech features are restricted to an instrument cluster display whose graphics have been completely redesigned to feature a horizontal rev-counter – said to have been inspired by retro racers from the 1980s – and central gear selection indicator.
Production of the TSR-S is now underway within Zenvo’s limited run of just five cars a year.
