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.

Detroit Electric SP:01 electric Lotus project not dead yet

Detroit Electric is still on board to produce the Lotus Exige-based SP:01 electric sports car, which has been delayed more than once already. According to the carmaker, the SP:01 prototype is currently undergoing testing at a facility in Europe, as we can see in the above photo provided by Detroit Electric. Details about the production schedule and on-sale date for the SP:01 are still unclear, but Detroit Electric says it will announce more about that in the coming weeks. Production was originally supposed to begin last year, but was delayed when plans to build the car in Plymouth, MI fell through. Production is now planned to take place in Holland, but there's still potential for future models to be made in Detroit. The company has stated that the SP:01 will come with a base price tag of $135,000. Like the Tesla Roadster, the Detroit Electric SP:01 uses a Lotus chassis. The car's electric motor provides 201 horsepower and 166 pound-feet of torque to the rear wheels, pushing the car to 62 miles per hour in 3.7 seconds, with a top speed of 155 mph. Range on a full charge is said to be more than 180 miles. The SP:01 has been off to a bit of a rocky start, but this bit of news shows there's still life in the project. Let's just hope it all continues smoothly. See what Detroit Electric has to say for itself in the press release below, or check out our original post about the SP:01 for all the details about the car. World's Fastest Production Electric Vehicle Prepares for Launch Detroit Electric, the international electric vehicle manufacturer, is finalising dynamic testing of its SP:01 pure-electric sportscar at a facility in Europe ahead of its introduction in several world markets. The lightweight, two-seat, rear-wheel-drive, open-top sportscar promises to thrill the EV market with its blistering performance and exhilarating dynamics. This latest version of the SP:01 has seen additional development work carried out by Detroit Electric's engineers and designers since a pre-production version of the vehicle was revealed to the media at events in Detroit, USA, and Shanghai, China, last year. Further details of the car and Detroit Electric's production and sales plans will be announced in the coming weeks.

Lotus Evora update coming, new models still on hold

The trials and tribulations at Lotus over the past several years haven't put the company in best financial position, and after the dismissal of Dany Bahar as CEO, the automaker seemed rudderless. Jean-Marc Gales (pictured above) is the new captain at the helm of the British sports car brand, and he seems like the complete opposite of Bahar. Where the former boss was hugely ambitious (perhaps overly), the current CEO has crafted a plan for a gradual turnaround under what he called a "logic-based" recovery in a recent interview with Autocar. The most logical part of Gales' plan is focusing on what Lotus can actually do. Instead of launching new products, he wants to continue to refine the current lineup. "We won't have the funds to build all-new cars in the next few years," he said to Autocar. The biggest of these updates includes a heavily revised Evora with more power and less weight to debut at next year's Geneva Motor Show. An even lighter-weight Cup model is planned for later. The Exige will get a revision in 2016. Gales also hints that a future, feather-light model like the 2-Eleven is on the docket, and a crossover is on the drawing board, according to Autocar, though not yet green lit. North America is also a priority. Lotus is forever linked to founder Colin Chapman's axiom to add lightness to the brand's models, and Gales is continuing that history with the Lightweight Lab. According to Autocar, in this huge room the company's models are completely disassembled with each part labeled. The entire staff is invited to come in and make suggestions on places to reduce weight and lower costs. "This brand is like a sleeping princess, but I believe she is starting to wake up," Gales said to Autocar, but he's keeping sales projections modest. Gales wants annual numbers to increase from about 2,000 units this year to 3,000 in 2015 with his streamlined workforce but intends to keep figures at that level for a bit, while the company stabilizes.
