Technical KO: Porsche Panamera Turbo vs. Mercedes-AMG E63 S Drag Race

We've already shown you what happens when the two uber-sedans are thrown at each other in a drag race (you know, the kind that used a standing take-off), as well as in a circuit battle. But what if the Affalterbach and the Zuffenhausen long-roof heroes we're discussing here engage in a straight-line battle that features a rolling start?

Sure, both these slabs of Germany pack all-wheel-drive, which means that a standing take-off shouldn't be an issue, but the rolling start we're here to discuss will highlight another tech aspect of these lavish velocity monsters, namely their trannies.

You see, while the Panny packs a dual-clutch PDK gearbox with eight ratios, the E63 features an AMG SPEEDSHIFT MCT (Multi Clutch Technology) nine-speed transmission. The latter isn't a dual-clutch unit, rather working as an automatic that has skipped the torque converter in favor of a clutch pack - here's a guide on this single-input shaft gearbox (as opposed to the two shafts of a dual-clutch unit) for those of you who want to get into the tech details of the matter.

Returning to the velocity battle we have here, the 612 Benz and the 550 hp Porscha got together on an airfield in Sweden, with this allowing us to clearly spot the speed difference between them.

We have to mention that the scale footprint difference between the two is noticeable, with the Porsche being around 250 lbs (115 kg) heavier than the Mercedes-AMG.

The Porsche Panamera Turbo was used as the camera car for the stunt we have here, so you should be prepared to admire the posterior of the gym-visiting E-Class.
