Overnight action from the 24 Hours of Le Mans

We won't go into a recap here, but there are still leading positions being fought for in all classes - it's so close that leads are changing when a car goes into the pits. We'll let the recap wait until the end of the race, so for now enjoy some shots from last night's action at the 24 Hours of Le Mans.

Are you the 2017 Porsche 911 GTS Targa?

Our spy shooters have caught a strange, mash-up beast wearing a Porsche badge. Superficially, this is a facelift for the 911 Targa that features new bumpers, door handles and a redesigned engine cover, along with new light graphics for the front and rear lights. But have a look around back, and you'll find two inboard exhaust pipes; they aren't right up against each other as on the 911 GT3, but are spaced about five inches apart. The shooters said the first time they saw that arrangement was last winter, on a convertible during testing. We saw it again more recently in spy shots of what was thought to be the 911 GTS coupe prototype at the track. But when the production GTS arrived, it wore the traditional quad-pipe at the corners. The theory put forward by the spy photog: the current GTS has a naturally aspirated engine, but facelifted prototypes they've been seeing all have turbo engines, so this could be the facelifted Targa coming in 2017, after the 991-model 911 gets a refresh. In that case, the GTS coupe prototype at the track would have also been a post-refresh, turbo-engined GTS. It's only a hypothesis, but more than one outlet has reported that Porsche is going all-turbo for the updated 2015 models – the new exhaust position and those 911-Turbo-like vents could be their identifiers. We expect to find out when the lineup is unveiled at the 2015 Geneva Motor Show, possibly codenamed 992 instead of 991.2.

'Faster. Farther.' dives into the history of Porsche racing tech

No doubt, Porsche has produced some of the best endurance racecars around, such as the turbocharged, slant-nose 935 of the 1970s and the ground-effects-enhanced 956 and 962 of the 1980s. But the company's most famous racecar, its first overall winner at the 24 Hours of Le Mans, was the 917.
The 917 embodied many of Porsche's technological achievements up to that point, such as the company's first 12- and 16-cylinder engines (the flat-16 was never used in competition), fiberglass bodies that implemented early aerodynamic practices and the use of new, exotic materials, such as magnesium and titanium.
The racecar was commissioned by the head of Porsche Motorsports, Ferdinand Piëch, to win overall at the 24 Hours of Le Mans in 1970, after he realized a loophole in the rules that allowed cars to compete with engines up to five liters in the Sport category if they were also production models. Piëch saw opportunity: the top prototype class was restricted to three liters; the production minimum to compete in Sport was 25 cars. And so, with much effort, Porsche assembled 25 "production" 4.5-liter 917s and had them parked in a neat line for the race inspectors to verify their legitimacy. It didn't take long before people realized the new Porsches were much faster than the prototype racers, with a top speed approaching 250 miles per hour.
