Birth of Twizy Renault Sport F1

Renaultsport is widely known for its crazy cars. But this one, we want to show you today, is special! This is Twizy Renault Sport F1 and this is a concept car that wants to make people think about what happens when you join together Formula 1 race car with a conventional electric car.

To create this extraordinary car guys from Renaultsport and Renault Sport F1 have combined their efforts. As a result, they got a racing car with one seat, a front splitter, side-pods, rear wings and the diffuser. In addition, Twizy Renault Sport F1 has a rain light in the rear “bumper”. Well, just as a race car!

The car doesn’t take much space. To be precise, it is 2.60 m long, 1.49 wide and 1.45 in height.

But the most remarkable thing here is that the Renaultsport stocked in the machine the kinetic energy recovery system (KERS). And it does not switched on when you press the «Boost» button on the wheel, but it is automatically activated on demand during 14 seconds. This gives the car an additional 80 hp of power and acceleration from 0 to 100 km in 6 seconds. Thus, the rated power of the engine is 17 hp only, but the total is already 97 hp. That`s it!

By the way, KERS system in this case consists of three basic elements:
1) electric motor-generator unit, which is directly linked to the driveshaft;
2) the special lithium ion battery;
3) and the KERS control unit.

The new Twizy Renault Sport F1 inherited 2.0 slick tires from Formula Renault. It got a wheel in the style of Formula 1, mirrors and optics from Formula Renault 3.5. The rear seat of the car was donated to the benefit of KERS. there is nothing more from Formula 1 at the car, since its maximum speed is only 109 km/h.

We think it is needless to explain that there will be no serial production of Twizy Renault Sport F1. Although, if all cars will be electric in the future, perhaps the idea with KERS would come in handy.

What else can we say? The French have worked hard, see what kind of results they have achieved in recent years.
