Renault reveals its concept for the Formula 1 car of 2027

The French car manufacturer used the Shanghai motorshow to unveil its concept R.S. 2027 - a 600kg closed-cockpit car that produces 1340bhp, which would mean a power-to-weight ratio never seen before in F1.

The concept is four-wheel drive, with four-wheel steering.

It would be powered by a small internal combustion engine, but will boosted by larger battery systems that are almost five times as powerful as those currently used in F1.

Renault believes that although road car technology is set to advance greatly in the next few years, it is important that F1 remains about the driver.

So while its concept includes a closed cockpit, this would be transparent and Renault proposes that drivers would use transparent helmets so fans can observe them in action.

The R.S. 2027 features active LED lighting to boost its aesthetics, as well as moveable aerodynamic parts such an active wings.

On the safety front, as well as the canopy, the car would be fitted with two titanium 'pop-up' rollbars activated in the event of an accident.

As well as its car concept, Renault also proposed changes to the F1 format.

It suggested fans would have greater access to telemetry, with Formula E inspired 'fanboost' available to help drivers in the closing stages of races.

Renault also proposes a grand prix format shake-up, with a long race of 250km (155 miles), plus a shorter sprint known as the 'Final Sprint'.

Weekends would also feature a night 'rookie race, held on Friday evenings for teams' reserve and young drivers.

Renault F1 managing director Cyril Abiteboul said: "One role of Renault Sport Racing is to anticipate the future of Formula 1 so that it draws a maximum number of fans in an environment consistent with Groupe Renault's objectives.

"We look forward to generating inspired conversations with the racing community, fans and enthusiasts through this concept that highlights our ideas and desires."
