Renault considers fielding its own F1 team again

Renault has a long history in Formula One, but while it successfully ran its own team until 2010, these days it participates only as an engine supplier – and just to the two Red Bull teams. That could be changing in the near future, though, as the latest reports indicate that the French automaker is considering fielding its own team once again. According to Autosport, the company has ruled out starting its own team again from scratch, but it is weighing the possibility of buying an existing team. The last time it competed was when it took over the championship-winning Benetton team in 2002, building it back up to win back-to-back world titles in 2005 and 2006. It subsequently dropped in form until Renault sold the team in 2011 to Genii Capital, which has run it under the Lotus banner ever since. The Lotus team continued using Renault engines with limited success until this season when it switched to Mercedes. With Caterham now gone from the grid, that leaves Renault with only one customer: Red Bull, which runs both the Red Bull Racing and Scuderia Toro Rosso teams under Renault power. It's a situation in which the French company apparently doesn't particularly revel, leading it to consider buying a team again and running it in-house. Considering the difficulty the Lotus team it once owned has encountered lately, reacquiring its old operation could prove the most logical step for Renault, but of course that doesn't mean that's what it will ultimately do. It could continue strengthening ties with Red Bull until it acquires a large portion of it (or Toro Rosso) – something which Audi is said to be eying as well. Or it could look to another team altogether. Mercedes, McLaren, Ferrari and Williams may not be up for sale, but we could easily see Renault taking over cash-strapped Force India or Sauber, or even pouring its resources into getting Caterham or Manor/Marussia back up to speed and whipping it into winning form.

This is how ground effects work in a nutshell

There are two ways to generate downforce. One is with all manner of wings and spoilers on the surface of the vehicle. The other is with ground effects. One you can clearly see, the other remains something of a hidden mystery. Fortunately, the good folks at Lotus and Goodwood are here to dumb it down for us non-engineer types. It's called Bernoulli's Principle, named after Swiss physicist Daniel Bernoulli who literally wrote the book on the subject way back in the 1700s. Countless engineers have spent their careers focused on its study and application, but the crux of the matter is that, as the speed of air (or other "fluid") increases, pressure decreases. Play with the air's increasing speed and decreasing pressure just right and you can generate downforce underneath the body of a car without significantly increasing drag as you would with surface spoilers. For evidence of how Bernoulli's Principle applies in practical terms, just look at the last Ferrari to pack a turbocharged V8 in the middle and the latest one. The F40 had a giant wing on the back, where the 488 GTB has none. But because the 488 uses underbody aerodynamics (or "ground effects"), it generates significantly more downforce than the winged F40 ever could, and at lower speeds. Ferrari, however, was not the first outfit to harness the power of ground effects. Lotus did with the legendary 79 that Mario Andretti drove to the world championship back in 1978. That was the genius of Colin Chapman, and to explain how it all works in layman's terms, our friends over at Goodwood Road & Racing brought in Colin's son Clive Chapman, head of Classic Team Lotus, to put together the video above.

This 450-hp electric Lotus Evora is powered by Tesla and Chevrolet

When someone mentions an electric Lotus, the first thing that comes to mind is the Tesla Roadster, the California-based automaker's first vehicle. That car started life as an Elise before being heavily massaged and adapted by Tesla's engineers. In a similar spirit, the people at Onpoint Dyno are close to finishing Blue Lightning, a track-ready all-electric Lotus Evora. Blue Lightning uses a Tesla drive unit and a Chevrolet Volt battery pack, both mounted in the middle in place of the Evora's 3.5-liter Toyota V6. It's putting down about 450 horsepower at the wheels. The car was built for time attack sessions, so power is fed through custom forged wheels and super sticky Pirelli PZero Trofeo R tires, the same ones found on the last Chevrolet Camaro Z/28. There is a custom digital instrument cluster in place of the Lotus gauges. There's also a regen paddle on the left side of the steering wheel. With a full charge, Blue Lighting should go about 120 miles. While the car runs under its own power, it's only about 90 percent complete. It has no power steering, no firewall in between the seats and the motor and battery pack, no A/C, and a large hole where the shift lever used to be. Other final touches include fine-tuning the brakes and suspension. There is also a custom rear bumper coming that should make it look more like the new Lotus Evora 400. Onpoint Dyno expects the car to hit the track in the next month or so. Related Video:
