Kia Stinger vs Mercedes-AMG E63

What's the difference?

There is nothing quite like a car company occasionally building a car that could be considered a risk. And there are all kinds of risks in the car business - the market isn't ready for that car, people don't identify your brand with this or that type of vehicle, the list goes on. And it's long. It's very easy for me to sit on the sidelines and say, "Pft, what were they thinking?" Few cars land on your driveway without years of thinking having already gone into their development.

The Kia Stinger is the kind of car that would have caused lots of thinking and plenty of hand-wringing at Kia HQ in Korea. Not because it was a bad idea - it wasn't. Not because it's a bad car - it is, in fact, the opposite. And not because SUVs have already changed the way we look at cars - Kia has done well out of that.

It's just that Kia has never produced a car like the Stinger. A five-door coupe-sedan, rear-wheel drive and with a focus on driver dynamics. Most of us know very well how the Stinger GT burst on to the scene in a blaze of well-deserved glory. It's not all about the GT, though. There's a whole range of Stingers and just below that very accomplished sports sedan is the Stinger GT-Line.

Feels like lately all the Mercedes-AMG buzz has been at the smaller end of the scale.

Most recently, the screaming GLA 45 S has arrived in Australia, pumping out more kilowatts and newton-metres than any compact SUV has a right to.

But here, we're doubling the cylinder count to eight, arranging them in a vee, and lighting the wick on AMG's powerhouse mid-size sedan, the recently upgraded E 63 S.

While the ferocious twin-turbo V8 and the rest of this beast's powertrain are unchanged, the car has been brought up to speed with some aero-focused styling tweaks, Merc's latest 'Widescreen' digital cockpit, as well as the MBUX multimedia system, and a tricky new multi-function sports steering wheel.
