The M5’s five-litre V8 powerplant may have been put out to pasture with the introduction of the new 5-Series, but German tuning firm has transplanted the M Power engine into the Z4 roadster.

The Z4 will be launched in South Africa later this year and BMW are reportedly working on a 3,2-litre straight six-engined M-version of the roadster.

But in the run-up to the launch of the so-called M Power version of the Z4, German tuning firm AC Schnitzer unleashed a 220 kW supercharged version of the car, CARtoday.com reported in May.

And for those who want even more performance from their Z4s, German tuner Hartge has transplanted the M5’s engine, which produces peak power of 294 kW and 500 N.m of torque, into the roadster.

The conversion from six-cylinder roadster to big bore BMW Z4 5,0 bullet was quite simple, Hartge engineers say - just pull out the current BMW power unit and shoehorn the M5 into the engine bay.

Then Hartge slapped on a deep, elaborate front spoiler, lowered the suspension and fitted phat 18-inch rims and tyres.

For those who might be interested in buying one of these bruiser cruisers, Hartge offers a two-year unlimited kilometres warranty on the converted Z4’s engine and drivetrain.
