Mercedes S63 AMG Coupe vs Porsche Panamera Turbo S in unusual lux showdown

We'll admit it, we're really looking forward to more time with the Mercedes-Benz S-Class Coupe. Compared to other high-dollar luxury coupes - we're looking at you Bentley Continental GT - it's more stylish, easily more affordable, and since it's a Mercedes, lacks the sense of fragility that comes with a more exotic name plate.
Auto Express has taken a whack at reviewing the new two-door S-Class, and for some reason, the British mag is comparing it with a Porsche Panamera. Now, while comparing the looks of an S-Class Coupe and a Panamera is a bit like holding a beauty contest between Kate Upton and Medusa, this isn't as bizarre a pair as you might think, particularly when you opt for the high-dollar S63 AMG Coupe and the Panamera Turbo S.
The two offer similar power outputs from their force-induced V8s - 577 horsepower in the Benz and 570 horsepower in the Porsche - and are even similar in terms of interior and exterior dimensions. The S-Class actually has an extra inch between the axles and is 1.2 inches longer overall (it's also about 300 pounds heavier). In the cabin, the S-Class also has a tiny bit more rear legroom, with 33.4 inches to the Panamera's 33.3.

Porsche considering turbo for new GT3 RS [w/poll]

Some automakers make one hardcore version of a sports car and are done with it. Or at least they make one at a time. Think Ferrari 458 Speciale, Lamborghini Gallardo Superleggera (or Super Trofeo Stradale or Squadra Corse) or Maserati GranTurismo MC. But not Porsche. It transforms the 911 into the hard-core GT3, the even harder-core GT3 RS, the you've-got-to-be-psychotic GT2 and the do-you-have-a-death-wish GT2 RS. The RS models take things to a further extreme, but what separates GT3 from GT2 models has traditionally been the use of foced induction: GT3s are naturally aspirated, while GT2s go turbo. But that could all be about to change.
According to the rumors making their round of the webosphere, Porsche is considering using a turbocharged engine for the next GT3 RS. The reason is that, as we all know, Porsche has already pushed the 3.8-liter flat-six in the existing GT3 about as far as it can go, and then some. And buyers expect not only a more bare-bones package with the GT3 RS, but also a bit of extra power.
Given that everything seems to be going turbo these days, the move might make some measure of sense, especially if Porsche wants to avoid with the GT3 RS the spontaneous combustion issues it faced with the GT3. But we can't help but wonder why, at that point, it wouldn't just skip the GT3 RS and go straight for the GT2.

Listen to the Porsche Macan's exhaust note ahead of its LA debut

As if we need further proof that the Porsche Macan won't just be another small CUV, it'll be a small Porsche CUV, the German automaker has released a video of the vehicle's raucous exhaust note. In short, the Macan will sport a far racier soundtrack than most of its competitors.
The raspy sound coming from one of the Macan's two turbocharged V6 engines sounds great (the video isn't clear as to whether we're listening to the base 3.0-liter or the Turbo model's 3.6-liter engine), and it's accompanied by a nice crackle on overrun. It isn't like a 911 or other flat-six model, but it is more or less what we expect a Porsche to sound like. We'll have all the details on the newest member of the Porsche lineup when it debuts later this month at the 2013 Los Angeles Auto Show. Scroll down for an official press release from Porsche, as well as the video of the Macan, and be sure to turn your speakers up.
