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.

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.

Lotus F1 team $186 million in debt

The Lotus F1 team has fallen on some hard times. Majority-owned by investment firm Genii Capital and having little to do with the British automaker with which it shares its name, the Enstone-based outfit has been widely reported to be in serious financial trouble. The extent of those difficulties were until now unknown, but a new report from Germany's Auto Motor und Sport reveals that the team is in the red to the tune of £114 million - equivalent to $186 million at today's conversion rates.
The lack in cashflow is widely believed to have been the impetus for Kimi Raikkonen's departure from the team in order to return to cash-rich Ferrari, and was one of the major factors in selecting Pastor Maldonado to replace him instead of a more proven and accomplished driver of Raikkonen's caliber. Maldonado brings with him major sponsorship funds from Venezuelan state oil company PDVSA. In speaking with the German publication, however, Lotus F1 chairman (and Genii co-founder) Gerald Lopez revealed that the lion's share of the team's debt - £80 million or $130 million - is with Genii Capital itself, a negative balance that isn't likely to affect the team's day to day. That leaves about $56 million which the team owes to outside parties, including Raikkonen, who has yet to receive the full pay he was contracted for.
The team has opted to sit out the first test session of the Formula One season at Jerez. Its 2014 chassis isn't ready and, given the relatively cold temperatures at this point in the year, the team wouldn't expect to learn much about tire performance and degradation. As far as the new engine goes, Lopez says that any knowledge gleaned by Red Bull, Toro Rosso and Caterham at the test session will ultimately be shared with Renault and through it back to Lotus as well. Lotus engineers helped develop the new KERS system with Renault regardless, so the team already has the energy-recovery data it needs. The team will instead prepare for the second test session in Bahrain, by which point it aims to have its new car ready to kick off the season. Lopez says that it has secured the funding to offset its costs for the season ahead, and that it is working to pay down its debt.
