Auto Express and Steve Sutcliffe are producing Llandow lap time videos again - this time with two German super-sedans.
Porsche Panamera Turbo is widely regarded as the fastest of all fast 4-door cars and currently holds Nürburgring 4-door car lap record. Mercedes E63 AMG S is a bit of an "unknown quantity" and hasn't been tested on track much, if at all.
Watch the video or head over to the Llandow page for full list of lap times.
