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.

Lotus C-01 motorcycle rumored to get 200-hp V-twin engine

Back in June, Lotus announced it was getting into the motorcycle business. Or, we should say, Kodewa and the Holzer Group are getting into the motorcycle business, and have acquired the rights to use the Lotus name. One way or another, we're now receiving word on some of the specs we can expect from the prototype dubbed C-01.
The Lotus motorcycle is being designed by Daniel Simon, the automotive futurist who has penned, among other things, the light-cycles for Tron: Legacy and the livery on the LMP2 racer Kodewa also fields under the Lotus name. So you know it's going to look pretty awesome, but what will make it go?
According to Visor Down, the C-01 is being tested with a V-twin engine sourced from an undisclosed supplier that produces 170 horsepower in stock trim but has been tuned to produce nearly 200 hp in Lotus trim. A pair of prototypes - one with carbon-fiber bodywork and one without - have already undergone several thousand kilometers of testing, and are said to be handling "very well."

Behind the scenes of Lotus' spectacular truck-over-F1 jump

A Lotus F1 car and the truck in which it's transported may both be powered by Renault and share a common JPS livery, but as far as size and performance are concerned, they're at opposite ends of the spectrum. So if you had to jump one over the other, you'd think it'd be a no-brainer to skip the single-seater over the tractor-trailer. Right? Well that may be the more logical conclusion, but it's not the way the Lotus team and its technology partner EMC decided to go for this latest promo. Instead they jumped the semi over the grand prix car. The stunt was obviously geared towards publicity, but while they were at it, they set a Guinness World Record for the longest truck jump at 83 feet, 7 inches. The previous record, according to Guinness, stood at 50 feet, 6 inches, and was set on MTV's Nitro Circus on November 17, 2008, by Gregg Godfrey at Rocky Mountain Raceway in Salt Lake City. That record stood for six years, but (as best we can tell) was set without the trailer attached, or the F1 car tracking underneath - which only makes this latest stunt that much more impressive. You may have seen the promo clip circulating the interwebs late last week, but we've included a making-of video below as well to show how the stunt team managed to pull it all off.
