Crazy study: the Twizy could even start in Formula 1-crazy studies Geneva Motor Show

With a spoiler like this, even a narrow-gauge electric vehicle like the Renault Twizy looks like a racing car.

Renault is successful in two completely different fields: as a manufacturer of e-cars and as a Formula 1 racing team. A new concept vehicle based on the Twizy will now unite both worlds.

HCorner wing, carbon, racing slicks and Formula 1 high-tech: Renault has upgraded its Twizy e-car with Formula 1 technology. The now presented concept vehicle with the nickname “Renault Sport F1”, like the racing cars, has a rear wing, racing slicks and body parts made of carbon.

For the drive, the hybrid system from Sebastian Vettel’s current bolide was adapted for the small car. While the additional electric motor in the Formula 1 car supports a V8 gasoline engine, in the Twizy study it works with another electric motor. This is 18 hp and acts as the main drive source.

The second electric motor is supplied with power by a braking force recovery system and provides its 82 hp for a short time when starting up and accelerating. Together, both engines come to 100 hp.

Ideally, the mini-mobile accelerates from a standstill to 100 km / h in six seconds. A maximum of 110 km / h is possible. In the tradition of the Formula 1 monoposti, the race version of the city runabout only has one driver’s seat.

No chance of series production

“Our goal has always been to develop technologies in Formula 1 that are also useful in our production vehicles,” explains Jean-Michel Jalinier, President of Renault Sport. "This project will certainly make people smile, but it also contains a message to be taken seriously: We have succeeded in integrating a technology as complex as the Kers system into a completely different type of vehicle."

The electric motor converts the kinetic energy into electricity like a generator, stores it in the battery and allows it to flow back into the drive train when required. Flanged directly to the crankshaft of the V8 unit in the Formula 1 racing car, it then transfers its thrust directly to the drive train. Unlike in Formula 1, KERS in the Twizy Renault Sport F1 does not support a combustion engine, but the electric unit.

Another difference: Since the Twizy Renault Sport F1 does not reach the speed of a Formula 1 racing car, there is not enough kinetic energy to charge the Kers battery when braking. The developers at Renault Sport Technologies and Renault Sport F1 therefore had to come up with an alternative system for this.

The solution is an energy generation mode that can be activated at the push of a button on the steering wheel, in which the Kers electric motor converts the mechanical energy that the Twizy’s drive motor produces while driving into electrical energy, similar to a bicycle dynamo.

The Supersport-Twizy hardly has any chance of a series production. The fast e-mobile should remain a pure show car.
