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 nearing decision on sedan versus crossover

Lotus may be comfortable for the time being developing newer and better versions of its existing sports cars, but it won't necessarily skate by on its aging product portfolio forever. According to a report from Reuters, Lotus and its Malaysian parent company DRB-Hicom are currently considering adding a new model to the British automaker's lineup. And in a further sign of the times, it seems likely that the new model would be either a sedan or crossover. "I'm a bit torn between an SUV and a four-door sports car – but in the end I can see that the SUV has the bigger market," Lotus CEO Jean-Marc Gales told Reuters. "We'd do an SUV that is very light, very fast on the track and has outstanding handling," in keeping with what Lotus is known for. It would not be the first sports car manufacturer to delve into either category, of course. Porsche rebuilt its business by expanding into both categories with models like the Panamera, Cayenne and Macan. Maserati has long offered successive versions of the Quattroporte, more recently launched the Ghibli sedan and will soon introduce the Levante crossover. Aston Martin has toyed with both, as has Lamborghini. Other marques like Ferrari and McLaren, however, remain resolutely opposed to either proposition. This past December, we reported that Lotus was preparing to go a slightly different route by offering a high-riding version of the Evora instead of a proper four-door sport-ute. This latest development, however, would appear to be quite different. The company's engineering division showcased the APX crossover concept back in 2006, and revealed the Eterne sedan concept as part of the grandiose plans of the previous Bahar administration in 2010. The last time the proposition came up this past August, nearly half of respondents to our online poll voted that Lotus should build a sedan, but not a crossover. Over a quarter of you said Lotus should built both, 2 percent voted for the crossover over the sedan, and 22 percent said Lotus should steer clear of either.
