Lotus reveals an even lighter version of the Elise Cup 250

For an automaker with very few resources, Lotus manages to keep things relatively fresh. The new Evora 400 is a blast to drive, even if it is just a heavily revised version of the car that debuted in 2009. The current Lotus Elise debuted back in 2010, and though it may have departed from our shores, Lotus keeps customers worldwide happy with a plethora of new variants. The latest model is the lightweight Lotus Elise Cup 250. Now, this isn't the same Elise Cup 250 that debuted last year, though the two cars are very, very similar. The main difference is weight, as is typical with a Lotus. Colin Chapman's tried and true saying, simplify and add lightness, is still true here. The new model weighs just 1,895 pounds, or 1,948 without the lightweight package. Last year's Elise Cup 250 was already quite svelte at 2,053 pounds. While you may think that shaving that much weight from an already light car must be the result of black magic or a localized black hole, the truth is far more simple. The Elise Cup 250 makes extensive use of carbon fiber, titanium, and aluminum for components like the bodywork, exhaust, and wheels. The rear window is plastic instead of glass, and the standard lead-acid battery is replaced with a lithium-ion battery. The rest of the car remains mostly unchanged. The car is propelled by a 243-horsepower supercharged 1.8-liter inline four. It can hit 60 mph in just 3.9 seconds, quicker than the more powerful Evora 400. There's plenty of aero to keep the car planted, but it's not a pure track car like the Exige. The Elise Cup 250 still comes with a full interior with a stereo, though there's no mention of cupholders. As exciting as all this may be, the Elise Cup 250 won't be coming to the US. Unfortunately, airbags and crash structures all add weight. For everyone else, the Elise Cup 250 is at dealers now.

F1 just got a whole lot quieter, and some people are really unhappy about it

The scene is the front straight of the Albert Park Circuit at the Australian Formula One Grand Prix, and what you see on track on either side of the gentleman wearing the orange hat is a Mercedes AMG Petronas being followed by a Lotus. The first major clue, as should be obvious by the nose of the Mercedes, is that this scene was captured last year. The other major clue in the photo is the gentleman in the orange hat: he's wearing earmuffs to silence the noise. We count at least four people wearing them, and that's before the camera pans. Some F1 fans have been pleased with the sound of the new 1.6-liter V6 engines, but it appears that the majority are not; the organizers of the Australian Grand Prix are threatening to sue because of a "lack of sexiness," and F1 impresario Bernie Ecclestone has declared he was "horrified by the lack of [noise]." YouTube user krookzeh has posted a video comparing last year's 2.4-liter V8 cars on the first lap at Albert Park with the new turbo V6 cars on the first lap this year. You can compare the sounds and the number of earmuffs in the short clip below. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

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.
