Lotus F1 Team promotes Joylon Palmer for next season

After letting its longtime protege Romain Grosjean go to the Haas F1 team, Lotus has named his successor for next season. Driving for the team as it transitions back to being the Renault factory outfit will be one Jolyon Palmer, the current reigning GP2 champion and possibly one of the best-poised drivers to make it into Formula One. The 24-year-old Brit has been steadily working his way up the formula racing ladder, winning races in Formula Two and GP2 over the past several years before winning the latter title last season. During that victorious campaign he also served as a test driver for Force India, before switching to Lotus this season and getting 10 grand prix practice sessions under his harness. Jolyon's own experience undoubtedly sealed the deal, but his upbringing surely put him in a prime position to make it in single-seater racing. He's the son of former F1 driver Jonathan Palmer, himself a past Formula Two champ before completing half a dozen seasons in Formula One. It's what the elder Palmer's been up to since leaving the grid, however, that's put the son in such a strong position. As head of MotorSport Vision, Jonathan Palmer controls five major racing tracks across the UK – including BrandsHatch, Outlton Park, Snetterton, Cadwell Park and the Bedford Autodrome. He also runs a couple of trackday programs, founded the now-defunct Formula Palmer Audi series and continues to operate the FIA Formula Two Championship, the BRDC Formula 4 Championship, and the British Superbike Championship. All of which gave young Jolyon plenty of room to run as he developed his career. Will that be enough to put the young Palmer in a position to win next season? Only time will tell. But he arrives at a pivotal time for the team, which is expected to transition back from the privately held Lotus operation to Renault's hands, running once again as the factory team – but saddled with an engine package that has been underperforming against the competition. One way or another, it ought to be an interesting time to be in Enstone. Related Video:

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.

Lotus Exige S Roadster coming this summer to a circuit near you

We haven't heard much about the Lotus Exige S Roadster since we first saw it at the Geneva Motor Show last year, but Lotus is now confirming the car will go on sale this summer. Of course, unless anything has changed since the car was introduced, Lotus' "ultimate roadster" will still not be coming to the US.
Lotus has released a new video showing its 345-horsepower roadster in action, and while it doesn't even show that much of the car, you can check out our live images of the Exige S Roadster in our gallery. The video, which looks like a knockoff of a Universal Studios movie trailer, is posted below.
