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 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 911 GT3 RS facing delay over GT3 fire problems?

Porsche has never been afraid to introduce variants of its cars. However, its even higher spec, next-generation 911 GT3 RS may be delayed from its planned launch this summer while the engines in the standard GT3s (pictured above) are replaced.
A delay isn't certain, but executives want to make sure the high-strung mill is no longer a problem before they press forward with another model using it. Germany's Auto Motor und Sport asked Porsche CEO Matthias Müller about pushing back the launch, and he responded that it was too early to say. The company's current focus is making sure the engines get fixed and working on internal measures to prevent this kind of flaw in the future.
When fires claimed two 911 GT3s in Europe, Porsche initially stopped the model's sales and asked owners to stop driving them. It finally diagnosed the blazes as being caused by a loose screw on a connecting rod, which then resulted in crankcase damage and an oil leak. The company is replacing the engines on all 785 affected cars. A source told Autoblog that under 200 customers were actually affected, and the other cars were either at port or dealer lots. Hopefully, the recall doesn't postpone the road-going GT3 RS too far because we want to see what Porsche has up its sleeve.
