Unique F81 BMW M3 Wagon Drag Races AMG C63 S Rival

To their credit, BMW engineers did develop the M5 Touring, which had a ferocious V10 engine. However, if you want the performance from an M3 sedan inside a family-friendly car, you're out of luck... unless you go custom.

Today's mid-week drag race from Carwow features a one-off M3 Touring, which would wear the codename F81 if it were a real production car. Everything about it is custom, and to test out if it's been built up to code, a rival arrives in the form of the C63 S Estate/T-Model.

Both wagons send power to their rear wheels, unlike the RS4 which has quattro. But where the C63 S leaves the factory with a 4.0-liter bi-turbo V8 making 503 horsepower, the M3 Touring has its old engine swapped out for a 3-liter inline-6. "63 NP" (no problem) has to be the most ironic license plate possible in this context.

According to our old records on the car, it started out as a basic 320d and had the 2-liter diesel replaced by an S55. It even borrowed the carbon fiber tower brace from an actual M3.

Serious mods were needed to have it looking like an M car. The bumper, hood and fenders have been changed at the front. But the back must have been a little more difficult, as the flares required some chopping and welding. It's even got the right wheels, the 20-inch 666M made famous by the M4 GTS. For extra acoustical impact, an straight-pipe exhaust was added.

We desperately want that sexy M3 to win, and thankfully, it's also got State 2 tuning bumping the power to 540 hp. So, with the introductions all done, it's time to watch the magic.
