Lotus Cars, Williams Advanced Engineering announce technical partnership

Sports car company Lotus announced a technology development partnership with Williams Advanced Engineering, more commonly referred to simply as Williams. Lotus says the partnership will be specifically focused on propulsion systems. And this has us very excited. Lotus doesn't need much introduction; it makes ultralight and spectacular handling sports cars. Williams is a bit more obscure, but it works on some of the coolest vehicles in the world. For decades the company has participated in Formula 1, and still has a team competing. It developed a wild 500-horsepower flat-six engine for Singer, and it worked with Jaguar on the C-X75 concept car and made stunt versions for the James Bond movie "Spectre." The company even has electric car experience with four seasons of Formula E and development work on the Aston Martin Rapide E on its prodigious resume. The subtext of these various Williams projects is that we could see almost any kind of powertrain show up in Lotus sports cars in the future. The companies could have some high-revving, high-output internal combustion engines for the near-term, then they could create electric drivetrains for future Lotus cars. Think first-generation Tesla Roadster but developed by a company with racing experience. Perhaps the two could even create some hybrids in between launches of the two powertrain types. Of course we're speculating, but none of this out of the question considering Williams' capabilities. In fact, since the Formula E experience is specifically highlighted in the Lotus announcement, we bet electric Lotus cars are all but guaranteed. We will be watching for developments with great anticipation. 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 planning new 400-hp 2-Eleven successor [UPDATE]

UPDATE: A previous version of this post suggested the Evora's new 400-horsepower V6 might find its way into the Elise, but sources indicate that it wouldn't fit. The text below has been updated accordingly. It's been nine months since Jean-Marc Gales took over as the new head of Lotus, and as Top Gear recently discovered, the former Peugeot chief is cleaning house. Gales doesn't put himself in the camp of past Lotus execs (Dany Bahar chief among them) who've reasoned that the company can only succeed if it introduces new and more upscale products. Instead he's focusing on the brand's existing models – namely the Elise, Exige and Evora – but don't think that means they'll just be skating by. On his watch, Lotus recently introduced the Elise S Cup (apparently the first model it ever introduced on schedule) and the new Evora 400 (ahead of schedule), and there are plans for more. Though Gales apparently has no intention of producing an engine in-house, the Toyota-based 3.5-liter supercharged V6 – now producing 400 horsepower and 302 pound-feet of torque – is slated to be slotted into the Exige as well. Perhaps most exciting, though, is the prospect of a successor for the 2-Eleven. That windowless speedster was the most extreme interpretation of the Exige, packing just 252 hp but weighing less than 1,500 pounds. The next version would weigh considerably more – closer to 2,000 pounds – but pack that new 400-hp engine to drive the power-to-weight ratio through the roof (if it even has one) in pursuit of a Nurburgring lap record. Don't expect it to switch to carbon fiber construction, though: Like his colleagues at Ferrari, Gales is convinced that aluminum is the way to go, offering comparable weight-saving benefits but at a fraction the cost. To ensure that these new products don't disappear in a cloud of tire smoke and irrelevance, Gales is also overhauling the way Lotus markets its cars. For one thing, he's opening new showrooms in key markets like Paris, Berlin, Monte Carlo and Abu Dhabi. For another, he's making sure Lotus actually keeps a database of its customers, something which it almost unbelievably didn't bother with until now. Those might not be the most exciting aspects of the business, but if that's all it will take to keep Lotus in the game, we're all for it.
