Porsche 911 RSR stops just long enough to have its photo taken

When it comes to Porsche and its rapidly escalating endurance racing program, all eyes may be on the new 919 Hybrid - and with good reason: that's the vehicle with which Porsche will be challenging the likes of Audi and Toyota for wins in the top-tier LMP1 class of the FIA World Endurance Championship and at Le Mans. But it's the 911 RSR that does and will continue to form the backbone of the factory's effort.
The 470-horsepower racing version of the road-going 911 took a one-two finish in its class at Le Mans last year, and also won its class at the Daytona 24 this past January as well. This year Porsche will field two of them in the WEC, another two in the United SportsCar Championship here in the US and will sell countless more to customer racing teams that will undoubtedly continue to rack up trophies in racing series around the world. This, then, might be a unique chance to see one standing still. Check it out in our gallery of live images above from the Geneva Motor Show.

Porsche reportedly working on new turbocharged flat-four boxer engine?

These days, we've seen just about every automaker dropping cylinders in an effort to appease tightening fuel economy and emission standards - and Porsche is no exception. Nearly three years after introducing an all-new V6 powerplant under the front hood of its Panamera sedan (launched with a range of V8 engines) comes word that Porsche is working on an all-new turbocharged flat-four boxer to replace the flat-six engines mid-mounted in its Cayman and Boxster models.
Specifics have yet to be learned, but reports say the engine is a derivative of the current 3.8-liter six (shown above) found under the rear decklid of the Carrera S, yet with two fewer cylinders. Fitted with a turbocharger, direct-injection and the automaker's VarioCam Plus, the new all-aluminum 2.5-liter flat-four will likely develop upwards of 350 horsepower and 360 pound-feet of torque. Redline should be about 7,500 rpm. Initial indications say that Porsche will only offer the new engine with its seven-speed PDK dual-clutch automatic, tuned to take advantage of the low-end torque, but a traditional six-speed manual gearbox has not been ruled out. Despite the loss of two cylinders, enthusiasts will likely embrace the new engine as it promises to be lighter, more fuel efficient and more powerful than the 2.7-liter and 3.4-liter sixes in the Cayman/Boxster today.
Even though Porsche has been using Volkswagen Group engines for years (e.g., Cayenne V6, Cayenne Diesel and upcoming Macan), all indications are that the new flat-four will not be shared. Instead, it will be kept in-house for the automaker's sports cars and possible future fitment in an entry-level 911.

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."
