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:

1989 Porsche 911 Turbo rolls out of Harry's Garage

It's getting increasing hard not to feel a little envious of Harry Metcalfe's collection of vehicles, especially with his latest purchase. He now owns the trinity of '80s European supercars with an '87 Lamborghini Countach, an '87 Ferrari Testarossa, and the recent addition of an '89 Porsche 911 Turbo. With the other two already featured in videos, the example from Stuttgart gets the focus in Metcalfe's latest clip. These turbos have a reputation for being a bit of a handful to drive, and according to Metcalfe that notoriety isn't entirely undeserved. With no power steering, floor-mounted pedals, oddly placed controls and lots of turbo lag, this era of 911 Turbo is difficult to master. However, it's a wonderful challenge that really engages the driver, according to Metcalfe. While a very different vehicle from the Countach or Testarossa, it's clear that this 911 Turbo is still a beloved member in Metcalfe's trio of '80s supercars. Let him give you a detailed explanation why in this video.

How Porsche got Patrick Dempsey into the driver's seat for Le Mans

How do you get to Carnegie Hall? Practice, practice, practice. Ask Patrick Dempsey and he'll likely tell you the same secret for landing a role on a hit TV show or, for that matter, driving a Porsche in the 24 Hours of Le Mans.
That's because, like McQueen and Newman, Dempsey has earned his place in that rarified field of actors who also race. He's competed in Baja and Grand-Am, co-owns an IndyCar team, and this year returned to Le Mans where he and his teammates Joe Foster and Patrick Long finished fourth in the GTE-Am class behind the wheel of their Porsche 911 RSR.
It's a grueling race, and the fluid transition between drivers behind the wheel is a key element to success. Check out the satirical video below to see how Dempsey and company got ready.
