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 runs the Emira hard - and sideways - on track

Lotus sent Gavin Kershaw – the British automaker's attributes and product integrity director – out on track with an Emira and a camera crew. In between reminding us that manual transmissions are wonderful and getting the Emira increasingly sideways, Kershaw's job was to explain how the last ICE-powered Lotus is still a Lotus. In this extended teaser, Kershaw offers us a look at a fresh new tidbit, that being the car's four driving modes. "Tour" mode will handle everyday driving, programmed for "maximum stability and control." "Sport" does what we all expect "Sport" to do, tightening responses and loosening slip angles. "Race" opens up even more slip angle, and changes the gauge cluster to display racy dials like the performance tachometer. Then there's the wonderfully named "Fully Off," which shuts down every nanny save the ABS. And remember, the Emira will be offered with two suspensions, either standard Tour or stiffer Sport, and will only come with hydraulic steering. Sounds like Lotus has delivered on its quest to make the Emira "for the drivers."  The engine in the V6 First Edition is the same Toyota-sourced supercharged 3.5-liter V6 found in the Evora, producing 400 horsepower and 310 or 317 pound-feet of torque depending on transmission — the automatic gets the greater torque, but why would you do that? This one comes just about fully loaded, graced with the Driver's Pack, Lower Black Pack, Design Pack, and Convenience Pack, plus optional 20-inch wheels with diamond-cut two-tone finish and two-piece brake discs with branded calipers. It won't cost anything to swap the wheels for silver or black versions. The only other big-time options we know about so far are the $1,400 Extended Black Pack, which adds more black accents in places like the roof, mirror caps, and exhaust finishers, and the $2,150 six-speed automatic to replace the six-speed manual.  Next year's base model will run with a turbocharged 2.0-liter four-cylinder procured from AMG, producing 360 hp and shifting through a dual-clutch transmission.  While you wait, the Emira V6 First Edition configurator is online and ready for flights of fancy. To get in one when they begin arriving Stateside, the V6 First Edition opens up the bidding in early 2022 at $93,900. Late 2022 brings a base four-cylinder Emira that starts at $74,900. Neither of those prices includes destination. Related Video This content is hosted by a third party. To view it, please update your privacy preferences.
