Lotus Evija's wild aero setup is detailed by chief aerodynamicist

The Lotus Evija is a car of firsts for Lotus. To that end, the company has spent a lot of time talking over the details. Today, we get to learn about the wild shape’s aerodynamics and what Lotus engineers were trying to accomplish. Richard Hill, chief aerodynamicist for Lotus takes a dive into all the details, and the video at the top of this post offers a great visual. “Most cars have to punch a hole in the air, to get through using brute force, but the Evija is unique because of its porosity,” Hill says. “The car literally ‘breathesÂ’ the air. The front acts like a mouth; it ingests the air, sucks every kilogram of value from it – in this case, the downforce – then exhales it through that dramatic rear end.” We can see what Hill means as we look at the Evija in photos. Instead of a regular front bumper, this one has pass-throughs that direct the air back into the side of the car. Lotus hasnÂ’t released the all-important coefficient of drag figure yet, but we have to imagine itÂ’s very low. The front splitter (below, left) is responsible for a few different things. The opening in the center takes in air to cool the battery pack that is mounted behind the seats. Then, the outer section of the splitter channels the air to the “e-axle” for cooling of the electrical components. And finally, it also produces downforce.  There are a couple more tunnels for air to pass through in the rear. These “holes” are likely the most distinctive design feature, especially when accentuated with the LED taillights. Hill says that these are also fully functional and help to reduce drag. “They feed the wake rearward to help cut drag,” Hill says. “Think of it this way; without them the Evija would be like a parachute but with them itÂ’s a butterfly net, and they make the car unique in the hypercar world.” On top of all these porous body structures, there are pieces that move. The rear wing can elevate upward from its flush body position and deploy into clean air above, creating more downforce. And then thereÂ’s an F1-style drag reduction system. This uses a horizontal plane that deploys from the car to make it slipperier through air. The final big piece of this puzzle is the underbody sculpting that directs air into the massive rear diffuser. This causes an upwash of air, in turn creating a massive amount of downforce. Hill sums it up quite nicely.

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 S IPS automatic transmission option arrives in October [w/video]

The Lotus Evora S IPS that the company showed drifting all around its test track earlier this year will be available in October, says Car and Driver. The kinder, gentler Lotus is fitted with the six-speed Intelligent Precision Shift transmission, an Aisin unit swiped from the Toyota Camry and retuned with Lotus electronics and actuators.
There are two 'regular' modes and two 'sport' modes on the IPS gearbox. The former include a traditional hands-off automatic and an auto mode with shifts handled by wheel-mounted paddles. The latter are a sport automatic setting that sharpens the car's responses and a manual sport mode for total driver control. The Evora S IPS hits showrooms in October. For now, you can take a look at Lotus' test driver giving it the beans in the video below.
