BMW M5 vs. Panamera GTS by MotorTrend

The 2013 models go head-to-head in California in this quite super sedan showdown.

For MotorTrend's latest "Head 2 Head" episode, Jonny Lieberman pits two of Germany's finest sports sedans - the BMW M5 and the Porsche Panamera GTS - against each other. Although the horsepower figures might match the 553hp M5 against the top-of-the-line, 543hp Panamera Turbo S, that model carries a significantly higher price tag. So Porsche in this comparison had to be represented by its newer (but less powerful) addition, the 430hp Panamera GTS.

An unfair match, then? Watch the video and see for yourself.
