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.

Top Gear caught filming Best of British near Buckingham Palace

YouTuber and car-fan extraordinaire Shmee probably had very little trouble tracking down the Top Gear film crew recently, as the group was putting together an episode that could accurately be described as "excessive." With its flag-waving (literally) Best of British theme, the TG guys gathered a jaw-dropping array of British cars, and parked them all right in front of Buckingham Palace to make extra sure that the point was driven home.
Top Gear hosts Jeremy Clarkson, Richard Hammond and James May were outfitted with a trio of Jaguar F-Types festooned with gigantic Union Jacks, with which to survey the landscape of British motoring glory. In the video below, you'll see that this includes any number of Mini, Aston Martin, Lotus, McLaren, Land Rover, Bentley and Rolls-Royce models (just to name a few), as well as a healthy dose of weird stuff that most people would never guess at being built in the UK. The lawnmowers and military vehicles are especially cool.

Lotus updates Elise with new Sport, Sport 220 models

There aren't a lot of models that stay on the market a full 20 years after their introduction. The Lotus Elise is one of those few, so to mark the occasion, the British sports car manufacturer is launching two new versions. Instead of simply dressing the Elise up with special trim and badges (which it has already done), the new models succeed the old ones by "adding lightness" and increasing performance in the classic Lotus style. Replacing the base Elise is the new Lotus Elise Sport, which cuts a good 24 pounds off the already featherlike curb weight – now down to 1,909 pounds. The 1.6-liter inline-four that is sourced from Toyota and enhanced in-house carries over with 134 horsepower and 118 pound-feet of torque for a 0-60 time of 6.0 seconds and a top speed quoted at 127 miles per hour. Fuel economy and emissions figures improve thanks to the decreased weight, but Lotus says the difference is most felt in the brand's signature handling dynamics. Those looking for a little more oomph may be more enticed by the upgraded Elise Sport 220. Taking the place of the outgoing Elise S, the new Sport 220 benefits from the same weight reduction as the Elise Sport, but packs the larger, more potent engine. The 1.8-liter supercharged four delivers 217 hp and 184 lb-ft of torque to deliver a 4.2-second 0-60 time and a 145-mph top speed. Along with the weight reduction, the new Sport models benefit from optimized throttle response, traction slip thresholds, and handling balance. They also feature new Bilstein dampers. Along with ten exterior colors available, buyers will also be able to choose between leather, Alcantara, or (our pick) classic tartan upholstery like the original 1976 Lotus Esprit S1. Unfortunately, we can't count ourselves among those potential buyers, since Lotus no longer offers the Elise in North America. The automaker is, however, tipped to bring the next generation back to these shores toward the end of this decade. And the incremental improvements that it constantly rolls out bodes well for what's to come.
