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 Emeya concludes winter testing, brings unique treats

Think of the Lotus Emeya as the sedan form of the Eletre SUV, transferring Lotus' newest brand values into a body style closer in spirit to the old Lotus. As the automaker marches toward production later this year, we've got a few more details on what's to come with the English foe of the Taycan competitor. Battery size is said to be 102 kWh; if that's accurate, that would be down slightly on the Eletre SUV's gross 112-kWh battery that provides a usable 109-kWh. Lotus says the sedan's range will be "broadly similar" to the Eletre, which is rated to go up to 373 miles on the WLTP cycle. The sedan, like its brother, is built on an 800-volt system capable of 350-kW fast-charging, and uses two motors to power both axles. A top-shelf Emeya R trim should pack the same power as the Eletre R, 905 horsepower and 726 pound-feet, the Emeya's lower profile and lighter weight taking a coupe of tenths off the Eletre's 2.95-second sprint to 60 miles per hour.  At least two wild specs separate the Emeya from the Eletre: A 55-inch augmented-reality head-up display. Lotus says the projection on the Electre is 29 inches. In addition to being "the largest and most advanced in any Lotus," it offers "a Snow Mode which turns the display blue, helping the driver to see the outline of the road more easily against a white background." Who needs an Apple Vision Pro, eh?  The sedan also fits an active rear spoiler that's four inches broader than the SUV's from front to back, at 11.7 inches compared to 7.7 inches. Adjusting the spoiler's angle on the SUV can produce up to 112.5 kilograms of downforce. The sedan's spoiler rings up a maximum of 215 kg of downforce at speed. The Emeya's top speed is an electronically capped 159 mph, six miles per hour below the SUV's, done to preserve battery health.  Lotus recently concluded a series of winter tests that are part of the company's three-year development testing across 15 countries, working out the Emeya in temps as low as negative 13 Fahrenheit and locking the car in a freezer at -40 F to gauge how its systems performed.  After going on sale in China, the Emeya heads to Europe and then to the U.S., so we shouldn't expect it until sometime next year, joined by the Evija hypercar. Car magazine said it saw a Lotus presentation that mentioned an MSRP of $100,000, almost identical to the base Porsche Taycan's U.S. MSRP.  Related Video:

Lotus F1 team $186 million in debt

The Lotus F1 team has fallen on some hard times. Majority-owned by investment firm Genii Capital and having little to do with the British automaker with which it shares its name, the Enstone-based outfit has been widely reported to be in serious financial trouble. The extent of those difficulties were until now unknown, but a new report from Germany's Auto Motor und Sport reveals that the team is in the red to the tune of £114 million - equivalent to $186 million at today's conversion rates.
The lack in cashflow is widely believed to have been the impetus for Kimi Raikkonen's departure from the team in order to return to cash-rich Ferrari, and was one of the major factors in selecting Pastor Maldonado to replace him instead of a more proven and accomplished driver of Raikkonen's caliber. Maldonado brings with him major sponsorship funds from Venezuelan state oil company PDVSA. In speaking with the German publication, however, Lotus F1 chairman (and Genii co-founder) Gerald Lopez revealed that the lion's share of the team's debt - £80 million or $130 million - is with Genii Capital itself, a negative balance that isn't likely to affect the team's day to day. That leaves about $56 million which the team owes to outside parties, including Raikkonen, who has yet to receive the full pay he was contracted for.
The team has opted to sit out the first test session of the Formula One season at Jerez. Its 2014 chassis isn't ready and, given the relatively cold temperatures at this point in the year, the team wouldn't expect to learn much about tire performance and degradation. As far as the new engine goes, Lopez says that any knowledge gleaned by Red Bull, Toro Rosso and Caterham at the test session will ultimately be shared with Renault and through it back to Lotus as well. Lotus engineers helped develop the new KERS system with Renault regardless, so the team already has the energy-recovery data it needs. The team will instead prepare for the second test session in Bahrain, by which point it aims to have its new car ready to kick off the season. Lopez says that it has secured the funding to offset its costs for the season ahead, and that it is working to pay down its debt.
