James Bond Lotus Esprit submarine car headed to auction [w/video]

We've covered many cars from the movies and TV that have made their way to auction (the original Batmobile, good old General Lee and even Bond's iconic Aston Martin DB5), but this one ranks up there among the rarest and coolest. RM Auctions has just announced that the Lotus Esprit submarine car used in the James Bond film The Spy Who Loved Me has been added to the docket for its upcoming auction in London, September 8-9.
Of course, there are dozens of Bond cars floating around out there in collections, but none as unique as this Lotus, which ended a chase scene in the movie by taking a long walk off a short pier and transforming itself into a submersible. Since CGI was a meaningless collection of letters back then, the producers of the film actually built a fully functional Lotus Esprit submarine for the shoot. They hired Perry Oceangraphic in Florida to turn one of their six Esprit body shells into a fully functioning submarine, and former US Navy Seal Don Griffin was tapped for piloting duties. RM Auctions claims the Esprit submarine cost over $100,000 to build at the time, which is about $400,000 in today's dollars.
The submarine car comes with a incredible story, too. After filming in the '70s, it was shipped to Long Island, NY where it was kept in a storage unit that was paid in advance for ten years. When the storage contract ended in 1989 and no one claimed the contents, they were sold off in a blind auction to an area couple who had no idea what they were getting. The car has been shown occasionally in the years since, but its value remained purely speculative, until now. To date, the most valuable Bond car we know of is the original Aston Martin DB5 used in Goldfinger and Thunderball that sold for $4.6 million in 2010, but when the gavel falls at RM Auctions' London sale in September, we'll find out if the car nicknamed "Wet Nellie" on set can beat it.

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.

Renault settles on Lotus, to take 65-percent stake in F1 team

Renault's coquettish moves toward becoming a constructor again have been news all season. The expected maneuver, should Renault say "Oui" to such, was for the French carmaker to repurchase the Lotus team - the team it sold at the end of 2010 to Genii Capital. Then last week we got the surprise news that Renault had been talking to Force India about taking a majority stake, but that information came with the context that Renault had discussions with several teams about such a move. Autosport reports that Renault has finally decided to get back together with Lotus, taking a stake worth up to 65 percent for 65 million pounds. The deciding factor was said to be the facilities that Lotus has available compared to Force India, including the Enstone factory formerly owned by Renault, plus a computational fluid dynamics program, driver-in-the-loop simulator, and a 60-percent-scale wind tunnel. The final shareholding stake will be split between Gerard Lopez at 25 percent and Renault ambassador Alain Prost at 10 percent. Renault will make a 7.5-million-pound payment immediately, completing the acquisition by paying 5.75-million-pounds per year for the next ten years. On top of that, Renault will invest a budget commensurate with those of Mercedes-AMG Petronas and Infiniti Red Bull Racing. The carmaker's board and CEO Carlos Ghosn have approved the deal, it is up to Lotus shareholders to agree to everything by Monday, when Autosport says the papers will be signed. The deal puts team drivers and the Red Bull engine supply in question. It should be expected for Romain Grosjean to remain, but keeping Pastor Maldonado is not a certainty. As for engines, Red Bull's engine supply contract states it must be Renault's priority, so Renault could stick with the Mercedes power unit Lotus currently uses for one more year, or help Red Bull get in bed with Mercedes. We should know more next week. Related Video:
