Watch Lotus F1 team careen through a mall in Renault Twizy EVs

The Lotus Formula One Team is sticking with drivers Romain Grosjean and Pastor Maldonado next year, but it's dropping Renault as an engine supplier in favor of Mercedes power. The 2014 F1 season is barely over, though, and that mean's there still a little time left to put those marketing dollars to work, while still having a little fun, too. To that, Renault has put Grosjean and Maldonado behind the wheel of two Twizy electric cars and unleashed them on The Dubai Mall for an ad for the little buggies. The place is one of the world's largest shopping centers, and it also houses an aquarium, an ice skating rink and even a dinosaur. It's a big place, and unsurprisingly, the two F1 pilots drift the little buggies with ease around every part of the complex. Grosjean even gets some time on the ice. Check out the ad for the quirky EV in the video above.

Lotus Eletre opens a new front in electric SUVs

Ladies and gentlemen, the new era of Lotus as an EV maker begins with this, the Eletre. It takes elements we've seen on the Evija battery-electric hypercar and Emira ICE sports car, wraps them in a larger package, jacks them up, and throws in a lot of new tech for the brand and the market. Let's start with size, which is the easy bit. The Eletre is 201 inches long on a 118.9-inch wheelbase, about 79 inches wide, and 64 inches high. Every one of those dimensions puts the Lotus within a couple of inches of the Aston Martin DBX: the EV being a little longer, with a slightly shorter wheelbase, a little wider, and a roof a couple of inches lower. For us, the side view most closely represents the form we had in mind based on recent spy shots. The front is intense, the yellow of the hero car making the greatest contrast with the polygonal void below. The lights above the leading edge are DRLs and turn signals, the main beams are recessed into that void, hugging the upper edge. The rear, with its Lotus script and full-width light bar fading into triangular intakes along the sides, clearly comes from the sports cars. It can glow in four colors depending on what it needs to communicate, and forms a connection with the light bar across the instrument panel. The SUV proportions and black roof are still playing tricks with our eyes, though; we can't help feeling the Eletre carries its bulk up high. The wheels are an optional set of 23-inchers that hide optional 10-piston (ten!) calipers gripping ceramic composite rotors. Lotus isn't ready to divulge specific battery capacity and motor outputs between those wheels. All we're told is the pack is more than 100 kWh and output starts at 600 horsepower. Every Eletre is all-wheel-drive, with a motor on each axle. The 800-volt electrical architecture can handle up to 350-kW fast-charging, 20 minutes at a station at that charge rate restoring 248 WLTP miles of the Eletre's estimated 373-mile range in WLTP testing. EPA numbers will come eventually. Lotus says the hauler will get to 62 miles per hour in under 3 seconds and hit a top speed of 161 mph. The electronic side mirror housings each contain three cameras, one camera for the rear views, one to help stitch a 360-degree overhead view, and one to help enable self-driving. The charge port is on the front left fender, but keen eyes might notice more shutlines atop the front wheel arches.

This is how ground effects work in a nutshell

There are two ways to generate downforce. One is with all manner of wings and spoilers on the surface of the vehicle. The other is with ground effects. One you can clearly see, the other remains something of a hidden mystery. Fortunately, the good folks at Lotus and Goodwood are here to dumb it down for us non-engineer types. It's called Bernoulli's Principle, named after Swiss physicist Daniel Bernoulli who literally wrote the book on the subject way back in the 1700s. Countless engineers have spent their careers focused on its study and application, but the crux of the matter is that, as the speed of air (or other "fluid") increases, pressure decreases. Play with the air's increasing speed and decreasing pressure just right and you can generate downforce underneath the body of a car without significantly increasing drag as you would with surface spoilers. For evidence of how Bernoulli's Principle applies in practical terms, just look at the last Ferrari to pack a turbocharged V8 in the middle and the latest one. The F40 had a giant wing on the back, where the 488 GTB has none. But because the 488 uses underbody aerodynamics (or "ground effects"), it generates significantly more downforce than the winged F40 ever could, and at lower speeds. Ferrari, however, was not the first outfit to harness the power of ground effects. Lotus did with the legendary 79 that Mario Andretti drove to the world championship back in 1978. That was the genius of Colin Chapman, and to explain how it all works in layman's terms, our friends over at Goodwood Road & Racing brought in Colin's son Clive Chapman, head of Classic Team Lotus, to put together the video above.
