Lotus opens the 2013 Formula One season with the launch of the E21 [w/video]

Lotus has broken the seal on the 2013 Formula One season, launching the E21 car at its factory in Enstone. With the regulations this year quite similar to those of last year, there are no dramatic changes in form compared to the E20. After some teams lobbied to be able to cover the stepped nose with a "vanity panel," Lotus retained the configuration, the team's technical director saying that the panel would add more weight and didn't make sense to put on the car unless it also added performance.
Beyond that, the E21 is said to be an comprehensive advance in its details - the suspension gets a new layout, the Coanda exhaust and the passive double DRS system are evolutions from last year, the front wing is "a continuation of concepts" from 2009.
After securing fourth in the Constructor's Championship last year, this is the chassis that drivers Kimi Räikkönen and Romain Grosjean will use to try and move the team up a place, which would mean beating one of the big three teams over the course of the season. The quietly and impressively consistent Räikkönen managed third in the Driver's Championship, and we're sure he wouldn't mind a move up in the standings, either.

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 pulled 55 pounds out of the Exige and added power to create this Sport 380

The hard-core Lotus just got harder. Or maybe corier? Anyway, the Lotus Exige Sport 380 is the most extreme iteration of the Elise and Exige yet. It hits 60 mph in 3.5 seconds, has even more downforce than the Sport 350, and weighs a full 55 pounds less than that car if you opt for the lightweight exhaust. With a curb weight of 2,425 pounds, that weight reduction means something. Mass was pulled out of a variety of places on the car, including the front splitter, front "hood" insert, wing, and diffuser surround, all of which are rendered in carbon fiber and save a cumulative six pounds. Swapping the rear glass to polycarbonate reduces weight by two pounds, a lithium-ion battery in place of the standard one removes 23, the carbon racing shell seats cut 13, and lighter wheels and brake discs lower the total by 22. Lotus even messed with the lights on the back, going from four big ones to two and making do with smaller fog and reverse lights, saving just over half a pound. That optional titanium exhaust saves an additional 22 pounds. And it's not like the Sport 350 was a porker. As the name suggests, there's more power coming from the supercharged and heavily massaged 3.5-liter Toyota V6. The Sport 380 makes 375 horsepower and 302 pound-feet of torque, up from 345 and 295 in the Sport 350. The 380 accelerates to 60 mph in 3.5 seconds (down from 3.7) regardless of which transmission you choose, but we highly recommend the six-speed manual over the auto, if only for its fantastic and beautiful exposed linkage. Tweaks to the aero package keep drag in check while increasing downforce by about 60 percent over the Sport 350, for a total of 309 pounds at top speed. Which, if you're curious, is 178 mph for the manual, 170 for the auto. So another vote for the three-pedal version. We'll have to remain curious, though, because sadly the current Exige is still not available in the US in any form, nor will it be. But Lotus is working on a new one that should arrive in a couple years to join the rejuvenated Evora lineup – the fantastic Evora 400 and upcoming, fantasticker Evora Sport 410.
