Road & Track conducted a "super sedan" showdown with the BMW M5 Competition Package, Mercedes-Benz E63 AMG-S (4MATIC), Audi RS7, Jaguar XFR-S, and Porsche Panamera Turbo.
The M5 (0-60 in 3.8 seconds; 1/4 mile in 12.0 @ 122.3 mph) just edged out the E63 (0-60 in 3.2 seconds; 1/4 mile in 11.5 @ 123.1) by 2 points.
The M5 and E63 finished 1 and 2, respectively.
Some amazing acceleration numbers for heavy luxury sedans. Hell, the E63-S is 6 tenths away from being 10-second car, stock.
