Mercedes-Benz A180 vs Nissan Z

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 Nissan Z is a real blueblood.

With Datsun, Nissan introduced the world to Japanese cars via a gruelling round-Australia rally in 1958 that had the country captivated. Within 10 years the 1600 made them respectable, but it was the 240Z of 1970 that also made them desirable.

Seven generations later, today’s RZ34-series Z – along with the Toyota/Subaru GR86/BRZ and Mazda MX-5 – embodies that nation’s tradition of affordable yet charismatic sports cars.

They’ve always been ripe for modifying as well, with Nissan leaning on its performance arm Nismo for 40 years. Which is exactly what the Z Nismo is all about, stepping up to take on the Toyota GR Supra, BMW M240i and Ford Mustang GT.

The old 370Z Nismo was a true corker. Let’s find out if this one does the family proud.
