Mercedes-Benz CLA45 vs Mercedes-AMG E43

What's the difference?

Mercedes-AMG left tongues wagging when it unleashed the original 45 series onto the automotive world seven years ago. It took many forms, including the pioneering A 45 hatch and the unconventional GLA 45 SUV.

That said, we’re here to talk about the third member of that family, the CLA 45 sedan (or coupe if Mercedes-AMG is paying your wage). And no, we don’t mean the old model.

Indeed, the second-generation CLA 45 is here, and it’s packing the most potent series-production four-cylinder engine to date – a title Mercedes-AMG has, of course, held before.

So, is the new CLA 45 a big-step up over its standard-setting predecessor? While it certainly helps that it is now only available in hard-hitting S form in Australia, the only way to really find out is to put it to test. Let’s go!

When is an AMG not really an AMG, but still a fitting homage to the models that built the brand?

The new E 43 is the eighth '43 after the SLC 43, GLC 43, GLC 43 Coupe and four C 43s, all of which arrived last year, and plugs a mighty gap between the mainstream E-Class line-up and the upcoming full-house E 63 S, while forming an almost exact philosophical fit with the E 36 and E 55 that helped put AMG on the map in the 90s.

How? Unlike the angry dinosaur V8 growl, supercar-like performance and generally hardcore demeanour we love about the current top-level models, the E 43 is more of a rapid grand tourer than a four-door supercar. Which is kind of what the AMGs of old were, before they sprouted exhausts from both sides and became more menacing than Mercedes.

The E 43 still boasts a muscular 295kW/520Nm from its twin-turbo V6 and all-wheel drive, but cloaks it all in an air-suspended package that's barely distinguishable from the AMG styling pack available from the base E 200 up.

It's priced $20,000 higher than the E 400 but still around $90,000 less than the E 63 S that arrives in June, and does nothing to dissuade the notion that Mercedes makes a car for almost everyone. And we're glad they do, particularly when the latest addition boasts a 4.6s 0-100km/h claim that would trump most mid-engined supercars of the 90s.

It also promises to be a star-badged alternative to the new BMW 540i, Audi S6 and even the Lexus GS F.
