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 to move immediately forward with new variants rather than new models

It took 1.5 years, but a DRB-Hicom managing director told Malaysia's Business Times that the company has "cleaned up" the situation at Lotus from its finances to its marketing and image. The clean-up job we're most interested in, the product portfolio, will be demonstrated by financial investment in a three-year program of "variants based on existing products - variants with improved technology, improved performance."
You'll notice mention of the word "variants" three times but no mention of the phrase "new models." We knew that with the death of the five-new-model turnaround plan dreamed up by ex-Lotus CEO Dany Bahar DRB-Hicom said there'd only be three distinct lines - which is the current number - but during Lotus' trouble-plagued 2012 it sold just 80 cars all year, and for a tense spell it really wasn't clear if DRB-Hicom would commit to even keeping Lotus alive, much less investing in it.
It's not clear how much is being put into in the three-year program of offshoot models like the 345-horsepower Exige S Roadster (pictured), but it might be fair to say this is where Lotus' revival really begins, and does so with baby steps. Autocar reports that DRB-Hicom has already put 100 million pounds into the English carmaker, and as its issues were worked through Lotus has sold almost as many cars in the first five months of this year as it did all of last. That has not only convinced the Malaysian minders to throw more money its way, but the UK's business secretary has also approved a 10-million-pound investment into Lotus through the Regional Growth Facility program.

Lotus F1 Team reveals new E23 Hybrid

Lotus is keen to leave a lackluster 2014 Formula One World Championship campaign behind it and race forward towards a new era, and this is the car with which it hopes to do so. The new E23 Hybrid is the twenty-third chassis to come from the Enstone-based team. As with the new Williams that was the first new chassis revealed for this year, the principal difference you can see is the more conventional nose to replace the twin-tusk setup of the E22, but there's more to it than that. For starters, it's the first new Lotus to pack Mercedes power after the team parted ways with Renault – the manufacturer that used to own the team and which has powered every car the team has built since Benetton signed with the French automaker way back in 1995. It also packs a completely new suspension setup after the original FRIC design in the preceding E22 was banned mid-season, forcing Enstone engineers to go back to the drawing board halfway through the championship. Word has it that, after earlier rumors suggested the team might not even make it back onto the grid, new sponsors will be added before the season gets under way in Melbourne on March 15 with the Australian Grand Prix. To pilot the new car, Lotus has retained the same two drivers as last year in Romain Grosjean and Pastor Maldonado. The team is hoping to perform better this season than it did the last, when it finished the constructors' championship way down in eighth place – the same result it achieved in 2009 under Renault ownership and the worst it had performed since the Toleman days in 1983.
