Lotus drops Renault for Mercedes F1 engines

With only three manufacturers supplying engines in Formula One this season, the teams have been fairly evenly split: Ferrari, Sauber and Marussia use Ferrari engines; Mercedes, McLaren, Williams and Force India run on Mercedes power; Red Bull, Toro Rosso, Lotus and Caterham employ Renault power units. But one important team is reportedly preparing to ditch Renault and switch to Mercedes for next year.
That team is Lotus, an outfit which has fallen off its pace the past few seasons but which has still been a vital partner for Renault. That's because until a few seasons ago, the team based in Enstone, UK, was owned by Renault and bore the company's name. The operation was founded in 1981 as Toleman, was rechristened Benetton in 1986, bought by Renault 2000, taking the company's name in 2002, sold to its current owners Genii Capital 2009 and adopting the black and gold Lotus livery in 2011. As Benetton, it ran Ford engines until switching to Renault in 1995, sticking with the French outfit ever since, but that decades-long partnership - which meandered through Renault ownership and back out again - is now apparently drawing to a close.
The departure of Lotus as a customer team ought to allow Renault to focus instead on its increasing ties with Red Bull, which has taken the Enstone team's place as Renault's principal team. It could prove a smart move for the Lotus team as well, as the Mercedes engines have been outperforming the Renault units this season by an order of magnitude: not only is Mercedes far outpacing Red Bull at the top of the standings, but each of Mercedes' customer teams is performing better than Renault's clients.

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.

Lotus Evija's wild aero setup is detailed by chief aerodynamicist

The Lotus Evija is a car of firsts for Lotus. To that end, the company has spent a lot of time talking over the details. Today, we get to learn about the wild shape’s aerodynamics and what Lotus engineers were trying to accomplish. Richard Hill, chief aerodynamicist for Lotus takes a dive into all the details, and the video at the top of this post offers a great visual. “Most cars have to punch a hole in the air, to get through using brute force, but the Evija is unique because of its porosity,” Hill says. “The car literally ‘breathesÂ’ the air. The front acts like a mouth; it ingests the air, sucks every kilogram of value from it – in this case, the downforce – then exhales it through that dramatic rear end.” We can see what Hill means as we look at the Evija in photos. Instead of a regular front bumper, this one has pass-throughs that direct the air back into the side of the car. Lotus hasnÂ’t released the all-important coefficient of drag figure yet, but we have to imagine itÂ’s very low. The front splitter (below, left) is responsible for a few different things. The opening in the center takes in air to cool the battery pack that is mounted behind the seats. Then, the outer section of the splitter channels the air to the “e-axle” for cooling of the electrical components. And finally, it also produces downforce.  There are a couple more tunnels for air to pass through in the rear. These “holes” are likely the most distinctive design feature, especially when accentuated with the LED taillights. Hill says that these are also fully functional and help to reduce drag. “They feed the wake rearward to help cut drag,” Hill says. “Think of it this way; without them the Evija would be like a parachute but with them itÂ’s a butterfly net, and they make the car unique in the hypercar world.” On top of all these porous body structures, there are pieces that move. The rear wing can elevate upward from its flush body position and deploy into clean air above, creating more downforce. And then thereÂ’s an F1-style drag reduction system. This uses a horizontal plane that deploys from the car to make it slipperier through air. The final big piece of this puzzle is the underbody sculpting that directs air into the massive rear diffuser. This causes an upwash of air, in turn creating a massive amount of downforce. Hill sums it up quite nicely.
