Lotus Emira GT4 car revealed, ready for the race circuit

It’s time for the Lotus Emira to go racing. YouÂ’re looking at the first photos of the Emira GT4 race car here, which is the competition spec version of the Emira road car we got to see revealed at this yearÂ’s Goodwood Festival of Speed. Lotus didnÂ’t provide a ton of details, but we know the important stuff. Its body is made of composite, and a bunch of changes are made in the name of aerodynamics and downforce. The clean and simple lines of the Emira are interrupted by items like the large front splitter and huge rear wing. By and large, though, the basic Emira design and structure remain the same outside. WeÂ’ll also note that the GT4 is hand-built, whereas Lotus is attempting to bring more automation to the road carÂ’s assembly. The engine used in the GT4 is the tried-and-true Toyota-sourced 3.5-liter V6 (not the new AMG four-cylinder). Per usual, itÂ’s fitted with a supercharger, and Lotus says itÂ’s good for up to 400 horsepower with a 7,200 rpm redline. You get a six-speed xTrac sequential transmission (the only transmission option), and the car is fitted with a limited-slip differential. Braking is handled by race-spec Alcon discs and calipers, and Ohlins coilovers keep the body in check. In all, Lotus says the dry weight is 2,778 pounds. This car was developed with RML Group, a British racing engineering company. “The all-new Emira GT4 is an exciting next step following the hugely successful launch of the Emira road car,” says Richard Selwin, Lotus Race Program manager. “We have worked hard with the team at RML Group to ensure this next-generation of Lotus GT car will deliver race-winning performance.” Those entering racing series will be allowed to buy this Emira GT4 cars for the 2022 racing season. However Lotus says availability will be very limited for the first year. It expects to be able to meet total global demand for 2023 as production of the race car continues. Pricing wasnÂ’t made available initially. Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

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.

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.
