Porsche 919 Hybrid revives Porsche's factory Le Mans efforts

After months of teasing with camouflaged testers, Porsche has finally unveiled its prototype entry for the 2014 World Endurance Championship, the 919 Hybrid. Porsche, you may recall, hasn't had campaigned a factory team at Le Mans in years, so the 919 is nothing less than their recommitment to endurance racing.
Combining a 2.0-liter V4 (yes, a V4) that revs to 9,000 rpm, the 919 produces around 500 horsepower with a pair of energy recovery systems. The first system recovers the heat energy from exhaust gasses as they pass through an electrical generator, while the second system is a bit more familiar. Using a setup similar to what is found on the production 918 Spyder, a generator on the front axle recovers kinetic energy from the brakes, which is subsequently stored in a battery system. That power can then be sent to the front wheels at the driver's command, effectively turning the 919 into an all-wheel-drive racecar.
Despite these various forms of motivation, Porsche doesn't claim to be seeking outright power supremacy, with Chairman Matthias Müller saying, "In 2014, it will not be the fastest car that wins the World Endurance Championship series and the 24 hours of Le Mans, rather it will be the car that goes the furthest with a defined amount of energy. And it is precisely this challenge that carmakers must overcome. The 919 Hybrid is our fastest mobile research laboratory and the most complex race car that Porsche has ever built."

Porsche Cayman GT4 looks sexy, rapid in the nude

Porsche doesn't officially have a name for its more hardcore version of the Cayman, yet. The speculation is that the coupe is called the GT4 as a little brother to the 911 GT3. However, the German sports car maker apparently is not interested in keeping the model's looks much of a secret because these latest shots show it without a hint of camouflage to speak of. The GT4 reportedly takes the GT3's ethos of more power, less weight and stickier-than-glue handling and brings it all to the Cayman. As these photos show, there's a much lower air dam up front with a cooling vent at the tip of the hood. Larger wheels are another obvious addition and are likely shod with some very sticky rubber. At the back, there's a double spoiler combining a wing and a ducktail. The power and gearbox for the GT4 remains a mystery, though. The rumor is that it uses a tuned version of the 3.4-liter flat-six in the Cayman S and GTS to make between 370 and 400 horsepower. A similar overhaul of the Boxster might be on the way, as well. A version of the convertible wearing some of the Cayman GT4's goodies was recently spotted testing. That one even had a manual transmission to make the prospects behind the wheel even more exciting.

Porsche continues facelift spree with 911 Turbo

If there's ever been automotive case for constant evolution, it is the Porsche 911. It seems like every time a new version of the rear-engined sports car debuts, Porsche is already hard at work on a facelifted version of it that changes some subtle, barely noticeable aspect.
Such is the case with this round of images of a facelifted 911 Turbo, which was seen undergoing winter testing alongside the facelifted, hardtop-version of the 911 Cabriolet we showed you yesterday. The new, 991-based 911 Turbo was just unveiled in May of 2013.
Like the Cabrio from yesterday, both the Turbo and naturally aspirated models shown here feature additional slats at the rear of the car, right behind the rear wheels. These slats on the standard model lend credence to what we learned yesterday - that even the regular 911 models could end up getting turbocharged mills.
