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 Motorcycles C-01 now 'ready for the road'

When we first laid eyes on leaked images of the Lotus Motorcycles C-01, we wondered if its laid-back, sport cruiser shape was really appropriate for a motorcycle bearing any connection with Colin Chapman and the company's famous "add lightness" mantra. We've now seen official pictures of the bike in multiple color schemes, including classic black and gold, British racing green and even a variant that resembles Martini livery, and while we think it looks pretty cool, our opinion hasn't really changed.
Perhaps we shouldn't be surprised that the C-01 isn't an embodiment of the Lotus ethos, as the company that intends to build it isn't really Lotus at all, its builders - German racing firm Kodewa and tuner Holzer Group - merely having licensed the name of the British sportscar maker. It was designed by Daniel Simon, who once worked for Volkswagen and consulted for Bugatti and is the man credited with creating the reborn Tron Light Cycles. Still, looking past its questionable heritage, the C-01 looks pretty darn awesome, and there are some interesting bits that have us looking forward to the production version that's reportedly due within the next two months.
As expected, power comes in at 200 horsepower, courtesy of a modified version of KTM's 1,195-cc V-twin engine. The chassis is made up of steel, titanium and carbon fiber, with a seat height of about 28 inches. Its wheelbase, at about 65 inches, is a full 10 inches longer than a real street-legal superbike, and its front end is raked way out in front with a 19-inch wheel. Those dimensions mean we shouldn't expect much racetrack prowess, unless its rider is only planning on going in a straight line. Indeed, with a claimed dry weight of under 400 pounds, the Lotus Motorcycles C-01 ought to be mighty quick down the quarter mile.

Lotus getting into the motorcycle business

Lotus founder Colin Chapman is famously quoted as saying something to the effect of "Simplify, then add lightness." We're a bit amazed that it took this long, but someone appears to be taking that message to heart at the British marque, losing a couple of wheels, a clutter of bodywork and a whole mess of weight. No, Lotus isn't planning another spindly Seven-style trackday racer, it's getting into motorcycles.
Well, sort of. As an automaker, Lotus apparently isn't directly behind this two-wheeled effort, but it does appear to have officially lent its brand and logo to a new company, Lotus Motorcycles, which counts former Volkswagen Group designer Daniel Simon, Germany's Holzer Group and auto racing team Kodewa among its partners. The latter builds and races Lotus' T128 Le Mans Prototype in the World Endurance Championship series.
The new company is touting an as-yet unseen motorcycle, a racing-inspired "hyper bike" called C-01, releasing only the image above - a carbon fiber fuel tank trimmed in Lotus' trademark black and gold livery. Details are tough to come by, but the project is said to include a powertrain good for around 200 horsepower and construction involving titanium, carbon fiber and aerospace-grade steel.
