As for the Zuffenhausen machine, keep in mind this is the pre-facelift version of the first-generation Panamera, hence the 500 hp output of the twin-turbo V8 motor.
The German long-roof happens to find itself in the same scale footprint league as the muscle monster. And we all know the Hellcat's blown 6.2-liter HEMI delivers 707 ponies.
Then again, the Porscha comes with a PDK dual-clutch tranny, while the Hellcat example we have here is fitted with a six-speed manual.
Given the output gap between the two go-fast machines, a standing start would've brought a balance, since getting the Hellcat off the line, with the 275-section tires of the thing, is anything but easy - keep in mind that the German machine comes in all-wheel-drive form.
However, these drivers decided to take things to the street, choosing the usual approach, namely rolling starts. Note that the beasts set off at around 40 mph, so there were no traction issues for the slab of America.
P.S.: If you happen to be in a hurry, you should know that the racing action awaits you at the 2:54 point of the video below, with the Hellcat being used as the camera car.
