"Drag race between Tesla Model S P85+ vs. BMW M5 E60 V10 on a 1/4 mile strip in Iceland."

And the winner is...

By the numbers, the V10 BMW M5 has the Tesla Model S P85 easily beat in terms of raw horsepower, but in the real world, numbers aren't all that matters.

BMW M5 E60 V10

500 HP at 7,750 RPM

383 pound-feet Of torque at 6,100 RPM

Redline 8,250 RPM

Notice how high the RPMs must be for the BMW M5 to achieve max figures?  That alone puts it at a distinct disadvantage to the Model S.

The Model S wins this one...with ease.  In fact, off the line it downright embarrasses the M5.
