The new BMW Z4 sDrive20i & sDrive28i reviews

Reviews for the new BMW Z4 in America have described sDrive20i & sDrive28i sum up the cars as breathtaking.

No more six cylinder technology

 What’s new about these cars? They no longer contain six cylinder engines anymore. They now have four cylinders. This may upset some traditional fans who prefer the older system but with Government emission regulations becoming more and more strict and fuel prices across the world seemingly never stopping to rise, it was a new feature that was essentially needed. Efficiency and sustainability are nowadays just as important as performance on sports cars it would seem.

Smaller engines

 Both the sDrive20i and the sDrive28i have smaller engines under their bonnets. Both of which are turbo charged but nevertheless more affordable to run as they are made to more economical.

sDrive28i engine

 The BMW Z4 sDrive28i now has a 2.0 litre four cylinder turbo charged engine. That may raise a few eyebrows as the current version is a whole 1 litre bigger, with the engine being a six cylinder 3.0 litre. The big difference is to bring about a more efficient and sustainable vehicle as mentioned before.


 The BMW Z4 sDrive20i also has a 2.0 litre engine. This is a downgrade in size from the current version containing a 2.5 litre sDrive23i. The newer engine will have a new generation of a four cylinder system.


 Special technology used within the car includes the new Turbo Valvetronic direct injection otherwise known as TVDI. This combines with a twin scroll exhaust turbo charger. This is expected to slowly replace engine cylinder technology.

Less power

 Unfortunately, as you may have guessed both variants have less power. This may not please fans as they would have expected more from BMW. The German luxury car manufacturers would be hoping that drivers attitudes have changed, in terms of demand for cheaper running costs instead of more power. Is that risk too big to take? It’s one that may have been left out of BMW’s hands as all new generation of cars are being made greener.

Both vehicles acceleration speeds remain quick of the mark which will act a consolation. Both speeds of racing from 0 – 62 MPH are reportedly extremely close.
