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.

Race Recap: For the 2013 Monaco Grand Prix, NASCAR comes to the principality

Lots of contact, debris cautions, trips into the wall, full-course yellows and a red flag - these are the kinds of racing terms you unbox when you want to have a conversation about NASCAR... or the Formula One grand prix of Monaco. In this case we're not talking about the Coca-Cola 600 at Charlotte, we're talking about 78 laps in the South of France that even featured a fallen camera cable just like that stock-car race.
This year, Mercedes-AMG Petronas drivers treated their chassis' like busses instead of F1 cars, Romain Grosjean treated his Lotus like a battering ram, Sergio Perez kept sticking his McLaren's nose in places and eventually got it smacked, and maybe the size of the drivers' mirrors should be changed instead of the tires as there were almost as many firsts as there were crashes. Plenty of F1 fans wish Monaco were removed from the calendar, yet even though it doesn't specialize in traditional thrills, that doesn't mean nothing happens during the parade through - and into - the barriers.

Lotus team out of Le Mans, full driver list published

We can scratch off one more car from the list for the 2014 24 Hours of Le Mans. The Lotus T129 LMP1 car has been dropped from the entry list of the 82nd running of the historic race, with organizers citing "a lack of preparation" as the reason. On a more positive note, the list of 168 drivers in 56 vehicles has been officially published for the June 14 race.
Like the Lotus team currently in Formula One, the Lotus T129 uses the iconic British brand's name and colors but is actually built by a separate company. It previously ran a Lola chassis in the LMP2-class (pictured above). The Le Mans organizers claim the car will likely be on display during the 24-hour race, but it won't make it's competition debut until the World Endurance Championship round at the Circuit of the Americas in September. The T129 is being replaced by an Oreca 03 chassis with Nissan power in the LMP2 class, entered by Millennium Racing.
The Lotus' retirement came as the teams had to send in the names of the three drivers nominated to race each car. This year there are racers from 26 countries with the most coming from France (39), Britain (29), the US (17) and Italy (15). The latest tally of entries breaks down to 9 LMP1s, 19 LMP2s, 9 LM GTE Pros, 18 LM GTE Ams and the Nissan ZEOD RC as the experimental Garage 56 entry.
