Mercedes-Benz A180 vs Volkswagen Id.4

What's the difference?

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?

The all-electric Volkswagen ID.4 Pro has finally landed on our shores! Hurrah! The benefit of waiting almost half a decade for it means we get some mid-life technology upgrades and interior features for the single variant that's available to us (at least for now).

The biggest question this mid-size SUV really poses, though, is has it been worth the wait? Is it practical enough? Is it fun enough? Let’s find out.
