Race Recap: 2013 Indian Grand Prix mostly calm with chances of Championships

The smog around the Buddh International Circuit got so bad over the weekend that the FIA had to change the practice sessions. Then the soft tires that Pirelli brought to be the options were found to degrade so quickly that teams had to change their qualifying and race strategies. The only man it didn't seem to affect was - guess who? - Sebastian Vettel, who put his Infiniti Red Bull Racing on pole position.
Behind him came Nico Rosberg and Lewis Hamilton in the Mercedes-AMG Petronas, Mark Webber in the second Infiniti Red Bull and on medium tires, Felipe Massa in the first Ferrari, Kimi Räikkönen in the first Lotus, Nico Hülkenberg in the first Sauber, Fernando Alonso in the second Ferrari, and the McLaren duo of Sergio Perez and Jenson Button. The tire strategizing didn't work out for Romain Grosjean in the second Lotus, who didn't get out of Q1 after only running the medium compound tire and lined up 17th.
The Indian Grand Prix has been held twice and Vettel has led every single lap of both races. If nothing else, we knew there would be at least one new thing about this Indian Grand Prix: there'd be a lap not led by Vettel since he qualified on softs and would have to pit before Webber and Alonso who were both on mediums.

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.

Lotus sells loads more cars, earns way more money

Sports-car company Lotus has reason to be excited. It released some facts on its sales and financial performance for the 2016 and 2017 fiscal year, and it has seen some impressive improvements. According to the company, it sold nearly 60 percent more cars in mainland Europe compared with the 2015/2016 fiscal year, and it sold six times as many cars in the U.S. compared with that year. This helped it go from a loss of GBP16.3 million for the previous year in earnings before interest, taxes, depreciation and amortization (EBITDA) to a GBP2 million profit EBITDA. The fact that those numbers are given before all those extra expenses is noteworthy, though, as it means the company isn't truly profitable yet, despite major gains. The company did report numbers that only excluded tax, and those show the company still lost money. But the good news is that it lost much, much less money than the year before. Before taxes for the 2015/2016 fiscal year, the company lost GBP41.2 million, and this year, it only lost GBP11.2 million. The company expects it will be profitable before tax in the coming year. So Lotus isn't perfectly healthy yet, but this, combined with Geely's recent acquisition, shows it's well on its way to becoming fit as a fiddle. We like the cars Lotus makes, so we hope that things keep getting better, and that we'll maybe get more Lotus models in the future, beyond just the Evora road car and 3-Eleven track car.
