Lotus Elise Sprint adds lightness to lightness

Lotus announced the introduction of a new Elise trim level that exemplifies founder Colin Chapman's famous phrase of "simplify and add lightness." The new Elise Sprint combines the weight savings of the current standard Elise, along with a number of Sprint-exclusive parts for what Lotus claims is the model's most significant weight loss yet of about 90 pounds over the old model, bringing the car's dry weight (not curb weight) to 1,759 pounds. The exclusive Sprint parts account for about 57 pounds of that loss. They include a lithium-ion battery, forged wheels, polycarbonate rear window, and carbon fiber for the seats, roll bar cover, engine cover, and access panel. Interestingly, the biggest savings come from the lithium-ion battery, which is roughly 20 pounds lighter than the normal battery. Lotus also includes the optional two-piece brake rotors and carbon fiber door sills to reach the 90 pound total. This all translates to slightly quicker 0-60 mph times for Elise Sprint models over their Sport counterparts. Both the 1.6-liter 134-horsepower Sprint and 1.8-liter 217-horsepower Sprint 220 models complete the run to 60 mph a tenth of a second quicker than the equivalent Sport versions, with times of 5.9 and 4.1 seconds respectively. The weight loss also results in a price gain. For either Sprint model, you'll end up paying an extra GBP5,000, which is a bit over $6,100 at current exchange rates. Of course, the Elise isn't available in the US anyway, so it's a moot point. Related Video:

Lotus and Aston Martin to hook up?

This has been a tumultuous year for Lotus - to say the least - from the company being sold off back in January to its CEO Dany Bahar being fired in June to its questionable financial status and rumors of the British automaker being sold off to another automaker. First, we heard that Volkswagen was interested in acquiring Lotus and parent company Proton, a rumor that was later dismissed. Now Automobile is reporting that fellow Brit Aston Martin could be in the market to work with or possibly even merge with Lotus.
While this is pure speculation at this point, such a venture could prove to be beneficial for both independent companies. That's because with Lotus focused on lightweight, relatively affordable sports cars and Aston Martin producing high-end performance cars, there is virtually no product overlap between the companies. The article suggests that a person or company wanting to merge these two automakers would have to raise between $1.1 billion and $1.6 billion in order to make a go of it, however.
We're not sure what to think of this latest rumor, but anything that can help get the struggling brand back to health at least has our interest.

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.
