Porsche LMP1 to use 4-cyl hybrid powertrain [w/poll]

With the Formula One season - and indeed his entire F1 career - now behind him, Mark Webber took advantage of his early release from Red Bull Racing to try out the new LMP1 which Porsche is developing, undertaking the final test session of 2013 before Porsche throws it head first into the FIA World Endurance Championship next April. The session - which followed previous tests at Magny-Cours, Monza, Paul Ricard and the Eurospeedway at Lausitz - was held at the Algarve circuit in Portimão, Portgual, in collaboration with Michelin, which is developing the tires for the car. But that's hardly the news here.
No, the news is the first confirmation we've seen on the type of powertrain Porsche has developed for its new Le Mans prototype: a gasoline-burning four-cylinder engine with direct injection and two energy recovery systems. This contrasts sharply with the V6 turbodiesel and single electric motor used by Audi in the R18 e-tron Quattro (or at least the outgoing version) or the naturally-aspirated V8 and single electric motor found in the Toyota TS030. Flexibility in the rules set down by the FIA and ACO give the manufacturers that kind of latitude, prompting F1 teams like Ferrari and Renault to consider developing their new engines for Le Mans prototypes as well.
At this point Porsche isn't saying how large its four-cylinder engine is or how much power it will produce. But it'll be interesting, to say the least, to see how it fares against the Audi and Toyota in next year's championship and at Le Mans when it'll be piloted by Webber, former Lola LMP1 driver Neel Jani and Audi's own 2011 Le Mans-winning pair of Romain Dumas and Timo Bernhard.

The 2014 Rolex 24 at Daytona: What we learned, what we saw

Two days after the flag dropped on the 2014 Rolex 24 at Daytona, people are still trying to figure out what it might portend for the rest of the season. In 24 hours, two minutes and 24 seconds, 695 laps were completed by the car that crossed the line first. During that time, 67 cars began the race, 18 of them retired. There was that accident, and a red flag. There were supposedly slower classes beating supposedly faster classes. There were 16 caution periods, including that yellow flag. And then there was The Decision. And Then The Uproar. And then The Reversal.
There was also some pretty good racing, so let's have one last look at the weekend. Oh, and there was that 1964 Ferrari 250 GTO Series II...
If you want to skip the reading bits and go to the photos, there's a high-res gallery of 158 images above and a couple more below. Enjoy.

Watch Evo pick its 2015 Car of the Year in this epic video

With just a few days left in 2015, it's the perfect time to check out Evo's annual Car of the Year test to determine the greatest performance vehicle of the last 12 months. The writers' picks for the 11 finalists spanned a breadth of engaging models and included: Peugeot 208 GTi by Peugeot Sport, Lamborghini Aventador SV, Seat Leon Cupra Sub8, McLaren 675LT, Porsche 991 GT3 RS, Porsche Cayman GT4, Honda Civic Type R, Ferrari 488 GTB, Chevrolet Camaro Z/28, Lotus Evora 400, and Mercedes-AMG GT S. For the venue to test the mettle of these performance machines, Evo stuck close to home this year and visited the twisting roads at the beautiful north coast of Scotland. Racing brothers Marino and Dario Franchitti also came along for the ride to provide two more voices in the competitive challenge to determine a winner. Evo's video explains why each model deserves to be among such rarified company but doesn't gloss over their faults either. There can be only one winner, though. We don't want to spoil it, so check out the clip for magnificent views of these performance machines through the Scottish countryside.
