On this episode of Head 2 Head, MotorTrend’s Jonny Lieberman pits the 2013 BMW M5 against the 2013 Porsche Panamera GTS in an epic super sedan showdown. The battle begins in California’s Mojave desert with a classic quarter-mile drag race. Then Jonny takes both V-8 powered sports saloons up to Big Bear, California to find out which one carves up the winding mountain roads the best.

The F10 M5 is powered by a high-revving 4.4-liter (4395cc) turbocharged that uses the BMW M TwinPower Turbo technology. The engine outputs 560 horsepower from 5,750-7,000 rpm and 680Nm (502 lb-ft) of torque from only 1500rpm. It comes in both manual and 7-speed DCT transmission. The base price of the F10 M5 is $90,695, but the model tested came close to $105,000.

Basically a sportier version of the current Panamera 4S, the $110,875 GTS is powered by a naturally-aspirated direct-injection 4.8-liter, 32-valve DOHC V8 with variable valve timing/tift and dry-sump lubrication mated to a seven-speed automated manual gearbox (PDK). The engine produces 430 hp at 6,700 rpm and 384 lb-ft of torque at 3,500 rpm.

So why has MotorTrend chose an underpowered Panamera to compete against the M5 super sedan? Here is what MotorTrend’s Jonny Lieberman had to say on the topic:

We chose the Porsche Panamera GTS instead of the Turbo for a few reasons. One is that, like the M5, the GTS is new. We’ve never tested it before. For us, it’s always important to do new versus new. Another reason is price. The GTS has a base price in the U.S. of roughly $111,000, which while still a fortune, is roughly comparable to the M5’s as tested price of about $105,000. However, Porsche likes to stab you in the heart with their options, so this particular GTS stickers for $144,000!

But saying that, the PanTurbo S STARTS at $175,000. Porsche offered us one, we declined it for this particular Head2Head. The last reason we didn’t use the

Panamera Turbo S is that it would’ve really beaten up the M5. Compare the Turbo S’s 0-60 time of 3.5 seconds to the M5’s 4.0. The GTS hits 60mph in 4.1 seconds. Also, the Turbo S’s quarter-mile time of 11.8 at 118mph is quite ahead of the M5’s 12.4 seconds at 114.2, keeping in mind that the scrappy GTS managed 12.7 at 107mph.

So which one takes the win?
