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.

Elon Musk buys James Bond's Lotus submarine, wants to install Tesla powerplant

Remember when we reported the long-lost-but-found-again Lotus Esprit submarine used in the James Bond film The Spy Who Loved Me had sold at auction in London for $966,560 (well, $863,000 plus a 12-percent buyer's premium)? At the time, the buyer's identity remained a mystery, but Jalopnik has reported and confirmed that the man with money to burn is none other than billionaire Elon Musk, CEO of both Tesla Motors and SpaceX. What's even more shocking (maybe not for Musk) is that he wants to install a Tesla electric powertrain in it and make it transform into a road-going car.
The story of the submersible Lotus' journey from movie star to prized possession of the eccentric Musk is remarkable. After filming ended in the '70s, the car was shipped to Long Island, NY and placed in a storage container that was paid in advance by the studio for 10 years. After the money ran out, the contents of the container were sold off Storage Wars-style in 1989 and won by an area couple. It was shown in public on occasion throughout the years, but its value remained a mystery until the gavel fell in London last month. While far from the most valuable Bond car to be auctioned off (that honor goes to the Aston Martin DB5 used in Goldfinger and Thunderball, which sold for $4.6 million at auction in 2010), the Lotus submarine is definitely the most unique.
Also worth noting is that the Lotus sub is more than just a prop. Without the aid of CGI, the film's producers needed an actual submarine that looked like a Lotus Esprit, and so they hired a company called Perry Oceanographic in Florida to build it and hired former US Navy Seal Don Griffin to pilot the sub during the film.

Watch the Lotus 3-Eleven run down Porsches and destroy the Nurburgring

The Lotus 3-Eleven is the automaker's most powerful production machine to date. Roughly a year ago, Lotus set out to show just how capable the 3-Eleven is by sending the open-top track-focused machine to the Nurburgring. Lotus claims the car set a blistering time of 7:06 around the track. Now in a belated celebration, automaker released two new, short clips of the vehicle sprinting around the Green Hell. There's no questioning just how capable the 3-Eleven is. In both videos, which are shot from the driver's seat, the track car chases down various Porsches at an impressive rate.

While there's some controversy over how Lotus set the time, the 3-Eleven's claimed Nurburgring pace is quicker than a Nissan GT-R Nismo and is just four seconds slower than a Lamborghini Aventador LP750-4 SV. Earlier this year, Germany's Sport Auto magazine took the 3-Eleven to the Hockenheimring where the track car managed to set a new record, besting the likes of the Porsche 918 Spyder. With a claimed dry weight of just 1,962 pounds, the 3-Eleven focuses emphasizes lightweight structure over massive power. Still, it's Lotus' most powerful production car with a 3.5-liter supercharged V6. In the right hands, the 3-Eleven can sprint to 60 mph in 3.0 seconds and managed to lap the automaker's test track 10 seconds quicker than the Evora 400. Marc Basseng, the racecar driver piloting the 3-Eleven, claimed the 3-Eleven could go even faster around the Nurburgring with less traffic. After watching these new clips, we would have to agree.
