The Zenvo TSR-S Has Bonkers Active Aero!
We first laid eyes on the Zenvo TSR-S last year at the Geneva Motorshow in March, but didn’t spend too long admiring its aggressive lines or aero trickery because, guess what, everything at the show had aggressive lines and aero trickery. Four figure horsepower (1,177bhp in this case) isn’t hard to come by at a show littered with million pound cars, but there was something about it that definitely stood out: its wing.
Zenvo claim that their wing increases centripetal downforce by curving away from the horizontal plane when it corners, and therefore decreases the chance of it snapping into oversteer. But don’t take my word for it, here are some words from the makers:
“The name ‘Centripetal’ refers to the centripetal force also known as ‘centre 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.”
While not as interesting or innovative, the wing can also act as an airbrake and go flat to decrease drag – more than necessary when trying to achieve its 0-60 time of just 2.8 seconds and top speed of 205mph. But when the majority of these cars ultimately won’t reach those kinds of speeds or ever make their way onto the track, do these tricked out wings just make for an ugly eyesore? I suppose that’s not for me to decide, but maybe you can in the comments below.
Active aerodynamics sounds good but does it really matter outside track days and it’s not legal for circuit racing so another great idea but really when is it practical.
