BMW X3 vs Mercedes-Benz A180

What's the difference?

BMW has recently launched its fourth-generation (G45) X3 range, which comprises three petrol variants including the entry-level 20 xDrive, mid-grade 30e xDrive PHEV and top-shelf M50 xDrive.

The new trio brings revised powertrains, new exterior and interior styling, increased standard equipment, enhanced technology and an emphasis on the use of sustainable materials.

We recently trialled the five-seater flagship to see if it has the right mix of performance and practicality to maintain the X3’s enduring appeal for Aussie families.

Meet the world’s most aerodynamically efficient passenger car. Mercedes-Benz says the drag co-efficient for this new sedan version of its fourth-generation A-Class is the lowest ever measured for a passenger vehicle.

Which is quite a claim, but you only have to look at it to see how much work has gone into marrying good looks with slippery aero performance.

The A-Class sedan is substantially longer and fractionally taller than its hatchback sibling, but does that mean it’s better, or simply different?
