Porsche 911 GT3 RS revealed in patent photos

Porsche has been taking its time developing the most hardcore 911 models for the latest 991 chassis. While the GT3 has been on the market for a little while, it suffered from some teething issues. The 911 GT3 RS is certainly on the radar since being spotted testing, but it's always better to get a look at a new car without all of the camo to hide the coolest parts. Thankfully, Car in the UK has some patent photos of the RS ahead of its debut, and they show off one mean-looking 911.
The first thing that you notice about the RS is that Porsche clearly isn't afraid to rework the latest 911's shape for its track-focused version. Each piece is slightly resculpted to squeeze the most out of it. Up front, the air dam has the same shape to the earlier photos. They also both highlight the upcoming model's tiny air inlet at the tip of the hood, the massive intakes in the rear fenders and general design of the rear wing with a ducktail underneath. The bubbled roof is much clearer here, where it was disguised in spy shots. You can also spot the slashing fender gills behind the front wheels that are a completely new feature.
The GT3 RS is the ultimate naturally aspirated 911 for the street, but according to Car, Porsche aims to take that even farther with the latest model. If these are the looks, then it's working. Unfortunately, the new version's powerplant remains a mystery. Though, given all the changes to the bodywork, the engine is almost surely getting tweaked over the 475-horsepower GT3. The RS is rumored to hit the road and be screaming down the track in 2015.

Porsche confirms four-cylinder Boxster, Cayman replacement for US

Those who've been anxiously awaiting the return of the four-cylinder Porsche will be glad to know that the wait is almost over. What's more, the quad-pot Porsches won't be kept away from US showrooms but will form an integral part of the company's North American strategy. Confirmation comes courtesy of Automotive News, which spoke to the company's chief executive Matthias Muller about its return to four-cylinder power. "First of all, we will have it in the Boxster and Cayman successor," Muller told AN. "And then we will see how it works and how successful it is and how the customers will react on that, and then we will take the next decisions." The model to which Muller refers is expected to be the 718 – a new line taking the place of the Boxster and Cayman, ostensibly allowing Zuffenhausen to start from scratch rather than "downsizing" the engine on existing models. The new range is anticipated to launch sometime in the middle of next year. Porsche is currently offering a 2.0-liter inline-four with 234 horsepower in the Macan (which we get with V6s) for certain markets overseas, but the 718 is expected to get a new flat-four 2.0- and 2.5-liter displacements with output edging up to 395 horsepower. The last time Porsche offered a four-pot in the US was with the front-engined 968 that wrapped up production two decades ago, but it hasn't offered a boxer four since 1976.

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."
