Porsche 911 GT3 RS getting all-new atmospheric engine

Porsche surprised many of its most puritanical enthusiasts when it took a decidedly more usable approach with the current 911 GT3. But when the new GT3 RS debuts, it promises to be a much more extreme departure. And a big part of that comes down to the engine. At the Detroit Auto Show this week, Auto Express spoke with Porsche R&D chief Wolfgang Hatz – who also happens to be head of engine and transmission development for the entire Volkswagen group. Hatz revealed that Porsche has developed a completely new engine for the GT3 RS, and while previous rumors suggested the RS would go turbo to fill in for the lack of a GT2 (and make the most out of its displacement), Hatz confirmed that it will be naturally aspirated. Considering that Porsche rarely goes downwards when it comes to 911 engine displacement, only upwards, we'd expect the new RS to pick up where the previous 4.0 left off. The new GT3 RS is also expected to pack a more extreme suspension, aero and stripped-out interior, but those hoping for an old-school approach may be disappointed to learn that the new RS will (at least at launch) only be available with the seven-speed dual-clutch transmission – though a manual version could follow if there's enough demand. In a related development, Hatz also hinted that the Cayman GT4 could debut at the Geneva Motor Show in March, with an even more extreme approach than the previous Cayman R. The new top-of-the-line Cayman is reportedly being developed to comply with GT4 class racing regulations but be fully homologated for road use. Related Video:

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 close to fix for 911 GT3 engine fires

It looks like 2014 Porsche 911 GT3 drivers might actually get to drive their cars again soon. Reports of fires affecting the track-ready Germans first began about a month ago. Then, a few days later, the automaker confirmed two of the five alleged blazes and said owners shouldn't drive their cars until further notice. Porsche then went so far as to offer to pick up the GT3s and transport them to the nearest dealer until the problem was identified and a fix was found. Finally, there appears to be a repair.
"We know the reason and the problem-solving measures. We're testing them," said Porsche CEO Matthias Müller to Bloomberg. The technical fix will be released to owners shortly.
The recall affects all 785 GT3s that have been sold so far, but there have been no reported injuries caused by the fires. When it first announced the safety campaign, Porsche said: "Internal studies to determine the cause of the engine damage have not been completed yet."
