Lotus to produce new crossover in China

Lotus and its parent company recently signed a joint-venture agreement with Chinese automaker Goldstar to build vehicles in China for local consumption, and according to the latest report from Autocar, it'll all come down to a new sport-ute. That's because the market for C-segment compact crossovers in China is huge. So big that it's impossible for Lotus to ignore. Porsche is reportedly selling 30,000 Macans in China alone each year, and is expected to reach 50,000 per annum there in the near future. "Six million SUVs will be sold in China this year, and more than half of those are C-segment models," Lotus chief Jean-Marc Gales told Autocar. "That figure is forecast to rise to eight million in four years. C-segment SUV sales alone will be bigger than the entire German market." Little wonder, then, that Lotus and Proton are keen to dive in. Technical details for the new Lotus crossover are still being worked out, but we'll likely be looking at a steel monocoque chassis clad in composite and aluminum body panels, riding lower than a Macan and weighing a good 400-500 pounds less. Power will likely come (at least initially) from the same 1.8-liter four and 3.5-liter V6 that power Lotus' sports cars, but driving all four wheels. A hybrid system could follow, and the finished product is likely to adopt a nameplate starting with the letter E – in the grand tradition of the Elise, Exige, Evora, Esprit, Europa, Elan, et al. According to Gales, "Our car will drive beautifully. It will be supple and comfortable but the emphasis will be on handling. It will be the lightest and fastest of its class on the track." This would be the first crossover Lotus would design, engineer and actually bring to market, but not, strictly speaking, the first time it has toyed with the idea. There was the APX concept (pictured here) it showcased in 2006 and the T5 that Proton essentially licensed Chinese automaker Youngman to build with Lotus' name on it. But the former was never put into production and the latter wasn't a proper Lotus. The design is currently being worked out before a prototype can be put together so that the joint venture can get the manufacturing license it needs from the Chinese government. So we're likely looking at another year or two before we see something solid. "Let's get the design right, then make a prototype," said Gales. "Let's make it beautiful and very light.

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.
