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.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

Seinfeld takes Seth Meyers out in the perfect Porsche

The latest episode of Comedians In Cars Getting Coffee features Seth Meyers of Saturday Night Live fame riding shotgun in what is a very special Porsche from host Jerry Seinfeld's collection: a 1973 911 Carrera RS 2.7. Seinfeld chose the "no-nonsense" sports car because he thought it fit his guest's personality (Meyers thinks motorcycles "are like the cigarette of transportation"), but we enjoy the chance to see one of these rare, über-valuable Porsches being driven on city streets - and in the rain, no less! What we don't like seeing is the Carrera RS being parallel parked behind a pick-up truck, though, fortunately, it seems that Seinfeld was able to avoid any front-end damage to the comparatively fragile Porsche.
Once at the coffee shop, the two comedians have a candid conversation about Meyers' time with SNL, from his early days on the show when he didn't think he was good enough to be a cast member to some of the high points in his career, such as SNL's "Really!?" segment that he performed in and how he became a writer for the show.
After coffee, when they're back in the car and Seinfeld opens up the throttle of the lightweight RS 2.7, he manages to eke out a big grin from Meyers - or maybe it was a grimace at the thought of driving in the rain on old tires. Whatever the case, be sure to watch the video below (and stay tuned until the end for a surprise).
