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 is building 60 extra light, extra aerodynamic Exige Cup 380s

Lotus is never done adding lightness and once again turned its attention to the Exige. Like so many other special Lotuses, this one, called the Exige Cup 380, makes the same 375 horsepower from its supercharged 3.5-liter V6. However, the weight savings is a significant 117 pounds compared with the 2,447-pound Exige Sport 380. This savings comes from the inclusion of many carbon-fiber parts including a one-piece rear hatch, side intakes, hood, front splitter, side sills, and seats, among others. Lotus also removed the gas struts for the hatch to save 2.2 pounds. And if that's not enough, you can save another 2.2 pounds by choosing the optional HVAC and air vent surrounds, and 22 pounds with an optional exhaust system. The Exige Cup 380 also produces significantly more downforce than the Sport, 43-percent more to be exact. That results in maximum downforce of about 441 pounds at the Cup 380's top speed of 175 mph. The car achieves this thanks to a revised front bumper and splitter, vents above the front wheels, more vents behind the rear wheels, and a new rear wing. Even the windshield wiper rests in a vertical position to aid aerodynamics. The Cup 380 doesn't just benefit from better aerodynamics and less weight. The rear tires are wider than the Sport 380 at 285 mm. The Cup 380 also has two-way adjustable shocks and adjustable front and rear anti-roll bars. Even the stability control can be adjusted to the driver's needs. The car is stopped by four-piston brake calipers at all four corners, and a standard steel roll bar protects the driver. If owners wish, they can also add an FIA-certified full roll cage. Lotus will only build 60 of these Exiges, and they're only available in Europe. They're not cheap either. In the UK, buyers will spend GBP83,000 in the UK and ˆ109,900 in Europe. That means this Exige would cost between $106,000 and $118,000, at current exchange rates. Related Video:

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."
