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:

Evo sets up duel of Porsche 911s

What's better, rear-wheel drive or all-wheel drive? That question has occupied auto enthusiasts for years, and so far, we've not really had a solid answer one way or the other. Evo has opted to take another whack at this tough question by pairing a pair of Porsche 911s against each other for a track battle.
In one corner, we have the two-wheel-drive 911 Carrera S, complete with the lickity-split PDK transmission, a sports suspension and carbon-ceramic brakes. In the other corner, it's the all-wheel-drive 911 Carrera 4S in a much mellower spec, with a seven-speed manual, as well as standard brakes and suspension. While the results seem like they'd be a foregone conclusion, some very British weather is there to act as the great equalizer.
We've got the full video down below. Have a look, and let us know if you agree with Evo's results.

Chris Harris gets filthy in a WRC-ready Porsche 911 RGT

Last time we rode with Chris Harris we were shotgun in the tan leather seat of his used-yet-immaculate Ferrari FF. This time we're strapped into a black racing bucket of a filthy Porsche 911 rally car, one that led Harris to effuse, "I don't think I've driven a more exciting car this year, hypercars included." The thrills come courtesy of a 997-series Cup Car that's been reworked by Tuthill Porsche to run in the RGT-class rally series that will piggyback on five World Rally Championship and European Rally Championship races this year. It's not quite the Rothmans Dakar monster, but the RGT series gives privateers an affordable way into rallying with cars that look different and are different from one another. This one kept its 3.8-liter, 444-horsepower 997 Cup engine, but the 39-milllimeter restrictor drops that to about 350 hp. Beyond that are a new rollcage, gear ratios, suspension, fuel tank, underfloor protection and just about everything else. Said the man who built it, it cost "a lot, and it's still costing." But Harris says even though you "have to have your wits about you," it's a hoot to drive. And this is one of the few times you'll hear the phrase "What a tool!" used as a compliment.
