Renault reveals new V6 power unit, and an audio clip

Eyes have now seen, and ears have now heard, the new Renault 1.6L V6 powerplant that will be coming to Formula One in 2014.

The French manufacturer unveiled its new power unit on Friday, dubbed the “Energy F1.” That is one of the goals of the new engine formula: trying to maximize efficiency and output, according to Renault Sport F1 president Jean-Michel Jalinier.

“From next year, one of greatest challenges in F1 will be to maximise energy efficiency and fuel economy while maintaining the power output and performance expected of F1 cars,” he said in Renault’s official release.

“Renault has pioneered this technology in its road car engine range with the Energy series. Naming the power unit Energy F1 creates an unbroken range, from the Clio through to our competition department.”

The visuals are explained in further detail by my NBC colleague Keith Collantine on the F1 Fanatic site here,  but they weren’t the only thing presented on Friday. Renault also released a 13-second audio clip on its website of what the new V6 engine will sound like.

Renault’s deputy managing technical director Rob White said the exhaust dominates the sound on the new engine, and that comparing it to the current V8 is a bit like comparing great bands.

‘‘The sound of the engine is the sum of three principal components, exhaust, intake and mechanical noise,” he said in that release. “On fired engines, exhaust noise dominates, but the other two sources are not trivial and would be loud if the exhaust noise was suppressed and contribute to the perceived sound of the engines in the car.

“I am sure some people will be nostalgic for the sound of engines from previous eras, including the preceding V8, but the sound of the new generation Power Units is just different. It’s like asking whether you like Motorhead or AC/DC. Ultimately it is a matter of personal taste. Both in concert are still pretty loud,” he added.

At first hearing, the new V6 engines are seriously similar to IndyCar’s new 2.2L V6 turbocharged formula that was implemented ahead of the 2012 season.

At the moment, Renault is confirmed with Red Bull and Toro Rosso for 2014. It also supplies Lotus, Williams and Caterham in 2013, but Williams has already announced a switch to Mercedes next year.
