Lotus Type 133 sedan caught testing in China

Before the Lotus Eletre battery-electric SUV debuted in March, Chinese car spotters snapped photos of prototypes in testing. The same has happened again with the Lotus codenamed Type 133. An image of the tester parked along a curb showed up on the Chinese site Weibo, with a camouflaged Eletre in the background left and an uncamouflaged Eletre parked opposite. The Type 133 is a four-door sedan being developed as a driver's car, benchmarked against and planning to take on the Porsche Taycan as well as the Audi E-Tron GT. Slated for a reveal next year, recent Lotus trademark applications for the names Envya and Etude lead watchers to believe the Type 133 will adopt one of those monikers for its debut in March, Envya getting the short odds. Lotus SVP of design Peter Horbury said the 133 wouldn't be just a smaller Eletre, we'll need to wait until the covers come off to know the truth of it. What we can tell for now is that the sedan doesn't look far off the kind of four-door we'd have expected from Lotus if the English maker had got into family sedans before the electric age. Peeking through the window, the driver's area gives off the same vibes as in the Eletre thanks to a squared steering wheel and minimalist instrument panel. An earlier spy shot picked up by Car News China shows a rear door with pillarless window. The biggest surprise is how long it looks. Some of that length could be a trick of the angle and the camera lens; even so, this won't be a wallflower. And why should it be? Said to sit on the same Electric Premium Architecture (EPA) as the Eletre — a derivative of parent company Geely's Sustainable Experience Architecture (SEA) that supports the Polestar 4 and the new Smart range — we expect overlap in powertrain possibilities. That could mean an entry-level battery pack of 92 kilowatt-hours juicing a dual-motor drivetrain with 595 horsepower and 524 pound-feet of torque, and a 120-kWh pack powering four motors producing 893 hp and 727 lb-ft. That latter model should get the Type 133 from standstill to 62 miles per hour in under 3 seconds. After the sedan debuts, the Type 134 SUV isn't anticipated until 2025, a challenger to the Porsche Macan EV. The following year, Lotus returns to its roots with the Type 135 sports car that will usher the current Emira into retirement. Related video:

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.

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.
