2015 Porsche Cayenne S

Oh, Porsche.
Just as the dust settles over the 911 GT3's no manual gearbox kerfuffle, the Germans have gone and yanked the yummy naturally aspirated 4.8-liter V8 from the Cayenne S and replaced it with a twin-turbo 3.6-liter V6. Is nothing sacred in Porscheland?
Perhaps not... but that's not necessarily a bad thing. After all, Porsche famously once said they'd never build a diesel, but when they did, it was actually rather stellar.

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 911 Aerodynamic prototype cheated the wind ahead of its time

You might think that sports cars would have the lowest drag coefficient of all cars. And yes, they do tend to be more slippery than, say, SUVs or convertibles, but the sleekest vehicles on the road tend to be EVs, hybrids and luxury sedans. Sports cars, on the other hand, have aerodynamically detrimental needs for downforce and additional engine cooling. Still, the Porsche 911 is better than most, and has only gotten more so over the years. Its relatively narrow track and compact form mean it has a smaller frontal area than some other sports cars, and the gradual sweeping back of its headlights and windshield have only augmented its capacity for cheating the wind.
This 911 prototype, however, is even more aerodynamic than most. It's based on a "G model" 911 from 1984, but employed such features as covered wheels, a new rear spoiler and a reprofiled front end to drop its drag coefficient from 0.40 to 0.27, making it as slippery as a modern sedan and better at cheating the wind than just about anything built up to that point, save for maybe the Tatra 77, Citroën SM or Tucker Torpedo.
Elements of this prototype ended up gradually making it into production Porsches for years to come, and you can clearly see early influences on the second-generation 964 and even on the 959. It's featured here as the latest installment in a video series on rare historic Porsches unearthed from the company archives, following previous clips that featured a rare V8-powered 911 and a mid-engined 911 prototype. Scope out the latest episode in the video below.
