Mercedes-Benz A180 vs Renault Arkana

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?

This time around my family of three has been reviewing the updated Renault Arkana Esprit Alpine mild-hybrid, and you might be wondering… why?

In a market that is positively bursting at the seams with established and new competition, including full-hybrid rivals like the Honda HR-V RS and Hyundai Kona Premium, the Arkana has its work cut out for it.

It’s also a slightly unusual proposition, pairing the raised ride height of an SUV with the swooping roofline of a coupe, while sticking with a mild-hybrid powertrain as more and more rivals make the jump to full-hybrid.

So, does this small French SUV coupe still have enough going for it to stand out from the crowd?
