Lotus to produce new crossover in China

Lotus and its parent company recently signed a joint-venture agreement with Chinese automaker Goldstar to build vehicles in China for local consumption, and according to the latest report from Autocar, it'll all come down to a new sport-ute. That's because the market for C-segment compact crossovers in China is huge. So big that it's impossible for Lotus to ignore. Porsche is reportedly selling 30,000 Macans in China alone each year, and is expected to reach 50,000 per annum there in the near future. "Six million SUVs will be sold in China this year, and more than half of those are C-segment models," Lotus chief Jean-Marc Gales told Autocar. "That figure is forecast to rise to eight million in four years. C-segment SUV sales alone will be bigger than the entire German market." Little wonder, then, that Lotus and Proton are keen to dive in. Technical details for the new Lotus crossover are still being worked out, but we'll likely be looking at a steel monocoque chassis clad in composite and aluminum body panels, riding lower than a Macan and weighing a good 400-500 pounds less. Power will likely come (at least initially) from the same 1.8-liter four and 3.5-liter V6 that power Lotus' sports cars, but driving all four wheels. A hybrid system could follow, and the finished product is likely to adopt a nameplate starting with the letter E – in the grand tradition of the Elise, Exige, Evora, Esprit, Europa, Elan, et al. According to Gales, "Our car will drive beautifully. It will be supple and comfortable but the emphasis will be on handling. It will be the lightest and fastest of its class on the track." This would be the first crossover Lotus would design, engineer and actually bring to market, but not, strictly speaking, the first time it has toyed with the idea. There was the APX concept (pictured here) it showcased in 2006 and the T5 that Proton essentially licensed Chinese automaker Youngman to build with Lotus' name on it. But the former was never put into production and the latter wasn't a proper Lotus. The design is currently being worked out before a prototype can be put together so that the joint venture can get the manufacturing license it needs from the Chinese government. So we're likely looking at another year or two before we see something solid. "Let's get the design right, then make a prototype," said Gales. "Let's make it beautiful and very light.

Lotus Elise, Exige recalled over oil line fire risk

Lotus is recalling 451 examples of the Elise and Exige from the 2007 and 2008 model years. The cars in question, built from December 1, 2006 to October 31, 2007 could be affected by an oil cooler line that detaches from its fitting. If the line comes loose it could release oil onto the engine and possibly start a fire, or onto a tire and potentially cause a crash.
A bulletin from the National Highway Traffic Safety Administration indicates the recall is expected to begin on March 4. Notified owners can take their cars to their dealers for repairs to the lateral oil cooler hose and hose fittings. You'll find the full release from the NHTSA below with more information.

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.
