BMW never made a Touring version of the outgoing M3, but that didn’t stop one inventive petrolhead from building his own. To find out just how fast this home-built super-estate is, Mat’s lined it up against a BMW M340i Touring.

Nick, the man who decided to build his own BMW M3 Touring, did a fabulous job. He didn’t just drop an M3’s engine into a 3 Series Touring and call it a day – he painstakingly carried over as many of the M3’s mechanical bits as possible. So, the suspension, brakes, gearbox, interior, bumpers, wiring, and even the flared wheel arches are all pukka M3 pieces.
He didn’t stop there, though, because he had the standard M3’s 3.0-litre straight-six twin-turbocharged engine tuned by Evolve. Now it produces 540hp and 680Nm of torque.
That’s 90hp and 230Nm more than a standard M3 Competition makes, and a whole lot more than the M340i Touring brings to the party. Sure, the M340i’s 3.0-litre straight-six engine is the same size as the M3’s, but it only has one turbocharger and puts out a much less impressive 374hp and 500Nm of torque.
But, don’t write off the M340i Touring just yet. Its eight-speed automatic gearbox has a much better launch control system than the M3’s notoriously finicky seven-speed dual-clutch automatic. And, the M340i sends its power to all four wheels rather than just the two at the back, so it should have more grip off the line.
Interestingly, the new BMW M340i costs from around £52,000, which is almost exactly the amount it cost Nick to build his one-off M3 Touring. But would he have been better off just taking his cash to a dealership and buying an M340i? Watch the race to find out.
