Porsche suspends ties with Maria Sharapova after drug test

Porsche has reportedly suspended ties with Maria Sharapova after the Russian tennis star failed a drug test. The German automaker stopped short of terminating its relationship with the athlete altogether as it awaits the results of a deeper investigation. The issue emerged at the Australian Open, where Sharapova reportedly tested positive for use of a drug called meldonium. Manufactured in Latvia and prescribed in many former Soviet Bloc countries, meldonium is used to treat heart conditions and improve cardiac circulation. It is not approved by the FDA for use in the United States, and the World Anti-Doping Agency added it to its list of prohibited substances at the start of this year. Sharapova admitted that she's been taking the medication for ten years now but that she did not keep up to date on the WADA's list. Since it is considered a prohibited substance, she's been excluded from participating in the Australian Open this year, and suspended from competition as of March 12. She was also scheduled to take part in the Porsche Grand Prix, a tennis event sponsored by the carmaker in Stuttgart next month which she will now apparently have to miss. One of the top-rated female tennis players in the world, Sharapova has served as a brand ambassador for Porsche since 2013. Other sponsors including TAG Heuer and Nike have also reportedly suspended their relationships with the athlete pending further investigation by the International Tennis Federation. Related Video:

Porsche 911 GT2 test mule caught in the snow

This may look like a weird, cobbled-together Porsche, but insiders tell us we're actually looking at the forthcoming GT2. Maybe even a GT2 RS. Those schooled in the intricacies of Zuffenhausen nomenclature will be suitably excited by now. But for the rest of us, the GT2 (with or without the RS) represents the pinnacle of the most hardcore 911s. It's essentially a 911 Turbo without the all-wheel drive but some other goodies thrown in – or to put it another way, it is to the Turbo what the GT3 is to the 911 Carrera. Porsche first did a 911 GT2 back in 1993 based on the 993-generation model. It then did another based on the 996, and then on the 997. But the last one we saw was the GT2 RS that came out in 2010, packing 612 horsepower channeled exclusively to the rear wheels through a six-speed manual transmission. The German automaker didn't do a GT2 version of the 991, but now that the entire model line is undergoing a transformation – and an near-complete switch to turbo power – it apparently has another one in store for us. Aside from ditching the Turbo's all-wheel drive, the new GT2 will be lighter and pack more power – as much as 700 hp, from what we hear. As you can see from the spy shots, the test mule spotted romping in the snow is also wearing larger exhaust tips and the signature GT2 RS black hood. Expect the finished product to wear its own shoes and a more extreme aero kit as well. The question on everyone's minds will be whether it will, like the latest GT3 and GT3 RS, be offered only with a dual-clutch transmission, a conventional manual, or the buyer's choice of either. We'll find out sooner or later as the most extreme of Elfens is tipped to surface late next year. Related Video:

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.
