Going by just the spec sheets, the Audi RS7 and Porsche Panamera Turbo are the same damn car. Think about it: Both are large-ish fastback-hatchback super sedans with twin-turbo V8 engines, all-wheel-drive, serious sporting pretensions and six-figure pricetags. They even fall under the same ginormous corporate umbrella (i.e. the Volkswagen Group).
But spec sheets don’t tell the whole story, which is why Motor Trend’s Jonny Lieberman (and the mag/network’s highly-personable, highly-vegetarian Stig-equivalent, Randy Pobst) tested these two Teutonic JATO-boosted crypto limos on the road and on the track. And while a clear winner does emerge, we certainly wouldn’t turn down the Audi or the Porsche if you gave us one. (In fact, the acceleration and quarter-mile times alone give us the giggles.)
