BMW are one of the very few car companies pushing diesel technology in Malaysia, but even they have not put an oil burner in all of their models. For the longest time, diesels have only been available in BMW sedans, hatchbacks and SUVs. Then their convertibles started to feature oil burners. Then the diesel engine was finally offered in the 6-Series.

Today, the only BMW car still not available with a diesel engine is the BMW Z4, not even in the latest E89 variant. Not until now anyway – what you see above is an attempt by an aftermarket tuner to join in on the whole green movement that’s sweeping Planet Earth.

It’s called the AC Schnitzer 99d and it’s essentially the new E89 BMW Z4 with its engine bay equipped with the 2.0 litre turbodiesel engine from the BMW 320d. The stock numbers have been tuned up to 190 horsepower and 420Nm, but yet the 99d in the name refers to the 99.18g/km of CO2 emissions the car is rated to produce. 0 to 100km/h can be hit in 6.9 seconds, and rated fuel consumption is as low as 3.8 litres per 100km combined.

AC Schnitzer is referring to their green tuning attempts as “Efficient Performance”, and a diesel engine is not the only thing that went into the Z4 – lots of weight reducing work was performed as well, shaving the Z4’s weight off by 230kg.
