Lotus Europa on 2040-cars

Listen to the Lotus Evora 400 make lovely noises

Automakers roll out loads of video content these days, but they often do so much editing and add so much background music that you miss out on the best stuff. With this video, Lotus shows they know what's important. This video shows Lotus's Evora 400 spending some time out on their test track in Hethel. The video is quite short and consists mostly of some onboard footage, but Lotus clearly invested in the sound recording. This Evora's 400 horsepower, supercharged V6 sounds brilliant as it screams around the course. We'll be getting a version of this car in the States this year. Lotus intends on selling the fittingly named Evora Sport 410 (for its 400 horse output) in America. It's possible we may see a lower-end model as well without the supercharger or with a smaller engine. No matter what though, great-sounding Lotuses are in our future.

Lotus won't rule out SUV, but first we'll get a new Elise

Not even Lotus can ignore the sales potential of SUVs. Speaking to media yesterday, Lotus CEO Jean-Marc Gales said "The SUV is an interesting market. We're working on a concept but haven't made a decision yet." Lotus has reorganized lately, and is cash flow neutral on a path to future profitability. Put away your pitchforks. Yes, Lotus is the last automaker we'd expect to make an SUV, but nearly every other carmaker has already given up resistance. And we surmise that even a Lotus SUV would follow the Lotus founder Colin Chapman's famous ethos of "Simplify, and add lightness." At least relatively. Or, as Gales put it, "We stick to our roots, because they are enviable roots." That means the new Elise, coming in 2020 and destined for America, will be a lot like the current model sold in other markets. As we reported last week, Gales confirmed that the next Elise will be slightly wider to accommodate side airbags, but otherwise will have similar dimensions and power-to-weight ratio. The Evora 400 Roadster is also still planned, but won't come stateside for at least two years. "Lotus will not fit electrical steering [systems]. They take away the steering feel." And while the SUV ship may sail, there are still a few heretical ideas left in Hethel. In confirming that the Elise will add assisted steering in the next generation, Gales assured us it would be hydraulic. "Lotus will not fit electrical steering [systems]. They take away the steering feel." Also off the table for Lotus is any kind of hybrid. Speaking to Autoblog, Gales explained that hybrid systems adds weight, complexity, and take up space. The first two items go against the core values at Lotus, and the third creates packaging issues. "Besides, when you have low mass it's easy to be efficient," the CEO said. He added that a pure EV might be something Lotus would consider, but not anytime in the near future. Lotus returns to the US this year with the Evora 400. Stay tuned for our first drive review in a couple of days (spoiler alert: the car is awesome). And beyond the Evora convertible and next Elise, Gales says "You will enjoy many more cars from our company." We can't wait.Related Video: Lotus Convertible Coupe SUV Performance lotus evora 400 jean-marc gales lotus evora 400 roadster

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.
