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.

Question of the Day: What's the greatest British car ever?

The British automotive industry has produced everything from high-production econo-commuters to staggeringly luxurious oligarch-wagons, along the way winning plenty of races and building plenty of beautiful machines. The original Mini led directly to the past half-century of transverse-engine, front-wheel-drive cars built everywhere, the MGB put the sporty little convertible into everyone's reach, and the Morris Oxford became the most beloved motor vehicle in India. So many to choose from, but we want you to pick one. What will it be? Related Video:

Lotus announces race-ready Exige V6 Cup and Cup R

Lotus has pulled off the wraps on two new versions of the Exige: the V6 Cup and the V6 Cup R. Based on the Exige S, the V6 Cup is built to be a dual-purpose street and track machine. The 0-60 dash should take just under 3.8 seconds thanks to a full 345 horsepower from a supercharged 3.5-liter V6 engine. Weighing in at 2,380 pounds, the V6 Cup should be an absolute riot to drive, and with a full FIA-approved roll cage, fire extinguisher and six-point race harnesses on board, it's plenty safe, too. Two-way adjustable dampers are standard, as are AP Racing four-piston calipers on all four corners. More importantly, drivers can expect to find the Lotus Dynamic Performance Management system in the cockpit, complete with Touring, Sport and DPM Off modes.
The V6 Cup R, meanwhile, is both lighter and offers more horsepower than the standard V6 Cup. The same blown V6 dishes out 366 horsepower in R trim, and the whole contraption tips the scales at 2,292 pounds. Of course, the same spate of race hardware is stock, minus the DPM system. A lightweight battery, track-spec tow loops and quick-release engine cover help separate the Cup R from its more civil sibling, as do performance brake pads and better oil and water cooling systems.
Check out the brief press release below for more information. Both of the new models are headed for a debut at the 2013 Autosport International Show.
