Lotus 3-Eleven may be the quickest track weapon you can buy

Germany's Sport Auto magazine routinely takes world-beating supercars around the short circuit at the Hockenheimring: Porsches, Ferraris, Lamborghinis... the works. But the top of the leaderboard has now been claimed by something altogether smaller and less powerful in the form of the new Lotus 3-Eleven. The most extreme expression of the Elise/Exige platform to date, the 3-Eleven is a track-focused machine of the highest caliber. At its heart sits a relatively humble 3.5-liter supercharged V6, tuned to produce 460 horsepower. But with composite body panels and a low curb weight, it rockets to 60 in under 3.0 seconds flat, and more poignantly laps the company's own test track ten seconds ahead of the Evora 400. Now it's clocked a lap around Hockenheim – sometimes host of the German Grand Prix – in just 1:06.2, just edging out the previous record held by a Porsche 918 Spyder. It also bests the Gumpert Apollo, and the similarly track-focused Radical SR3 SL... not to mention everything else Sport Auto has ever taken to the track. What's even more impressive is that the magazine's road test editor Christian Gebhardt completed the lap on stock rubber and on a cold track that didn't get any warmer than 46 degrees Fahrenheit. Just imagine what it'd do on even semi-slicks and a warm track surface.

Driven by Christian Gebhardt, a highly accomplished driver and Road Test Editor for "sport auto", the Lotus 3-Eleven lapped the Hockenheimring short Circuit in an incredible 1 minute 06.2 seconds. This time was even more impressive considering that the 3-Eleven was on standard road tyres and the fastest lap was completed in less than perfect weather, where temperatures did not get higher than 8 degrees Celsius. Jean-Marc Gales, CEO of Group Lotus plc said, "Christian set a fabulous lap in less than ideal conditions.

Lotus Elise Sprint adds lightness to lightness

Lotus announced the introduction of a new Elise trim level that exemplifies founder Colin Chapman's famous phrase of "simplify and add lightness." The new Elise Sprint combines the weight savings of the current standard Elise, along with a number of Sprint-exclusive parts for what Lotus claims is the model's most significant weight loss yet of about 90 pounds over the old model, bringing the car's dry weight (not curb weight) to 1,759 pounds. The exclusive Sprint parts account for about 57 pounds of that loss. They include a lithium-ion battery, forged wheels, polycarbonate rear window, and carbon fiber for the seats, roll bar cover, engine cover, and access panel. Interestingly, the biggest savings come from the lithium-ion battery, which is roughly 20 pounds lighter than the normal battery. Lotus also includes the optional two-piece brake rotors and carbon fiber door sills to reach the 90 pound total. This all translates to slightly quicker 0-60 mph times for Elise Sprint models over their Sport counterparts. Both the 1.6-liter 134-horsepower Sprint and 1.8-liter 217-horsepower Sprint 220 models complete the run to 60 mph a tenth of a second quicker than the equivalent Sport versions, with times of 5.9 and 4.1 seconds respectively. The weight loss also results in a price gain. For either Sprint model, you'll end up paying an extra GBP5,000, which is a bit over $6,100 at current exchange rates. Of course, the Elise isn't available in the US anyway, so it's a moot point. 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.
