Now’s your chance to buy Lotus founder Colin Chapman’s 1981 Turbo Esprit

Lotus founder and Chairman Colin Chapman’s former 1981 Turbo Esprit Series 3 sports car is for sale, and it looks fantastic in its metallic silver exterior imprinted with “turbo esprit” on both sides and the bonnet, and contrasting red leather interior. Built in February 1981 but not registered until August, it was ChapmanÂ’s personal car until his death in late 1982, and was also driven at one point by former Lotus Formula One driver Elio de Angelis. Chapman even arranged for British Prime Minister Margaret Thatcher to drive it, at the Norfolk Airport in 1981. Thatcher was quoted in the local paper as saying it was “lovely to drive.” Right, then. Lotus built the car to ChapmanÂ’s specifications, with a lowered and modified suspension, modified bodywork to reduce wind noise, special brake pads and features like power steering and air conditioning that didnÂ’t figure in production models. Chapman, who suffered from hay fever, also had pollen filters installed, plus a roof-mounted Panasonic stereo system. ThereÂ’s also a specially assembled, blueprinted engine; Esprit Turbos of that model year featured a 2.2-liter turbocharged inline-four that made 210 horsepower and 200 pound-feet of torque. This was also the first Esprit model to be fitted with BBS alloy wheels. After ChapmanÂ’s death, the car was maintained for a few months by the companyÂ’s Factory Service Department, and eventually made its way to a succession of private owners. The car is currently on its sixth owner across seven transactions (one ended up re-acquiring the car), but it has just a hair over 11,000 miles on the odometer, with a new clutch slave cylinder and radiator core installed in the past decade. “This vehicle has lived a pampered existence and is a testament not only to its rich pedigree but to those who have cared for it over the years,” says the listing at Mark Donaldson Ltd., which claims it comes with extensive records. According to Top Gear, the seller is looking to fetch at least 80,000 pounds, or around $97,000. Related Video:    

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.

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.
