What is it?
When the first-generation Mercedes-Benz CLS was released in 2004, it had things more or less its own way. There wasn't exactly a plethora of four-door coupés for it to argue against.
You might argue there aren't any four-door coupés around now, either. But this newly muscularised (at the expense of some of its elegance) second-generation CLS does at least have some proper, direct competitors. There's Audi's A7 (which, to my eyes, now outdoes the latest CLS in the sleek stakes) and the BMW 5-series GT (which doesn't but, bless it, is having a go).
Our test CLS was a left-hooker, briefly visiting the UK for a head-to-head test against an A7 to be screened on these pages in a couple of weeks' time. Previously, we've been impressed with the CLS abroad, so the pertinent question is: how does it translate to British roads?
What’s it like?
The CLS feels keener, flatter and sharper than the E-class, which, given that it's notionally a more dynamic version of that car in all senses, is the way it ought to be.
Mercedes has made a big play of the new electric power steering system on the CLS (its first). It's smooth, accurate and well weighted, albeit fairly devoid of feel, like most systems of its kind. There were some slightly inelegant buttons on the steering wheel of our test car, too.
Driving a left-hooker in the UK seldom flatters a car's ride because you sit over the worst parts of the road. Our CLS, which had standard coil springs rather than the optional air springs, was generally good, but not without an occasional thump over bigger imperfections. The dynamism enhancements have not come without a small penalty, but it's far from one you'd complain about too vigorously.
Nor is there much cause to complaint about the drivetrain. The 350 CDI V6 diesel (actually a 3.0) is smooth and exceptionally quiet and uses the ratios of its seven-speed auto intelligently. It is, however, slightly reluctant to kick down in start-up E mode and is preferable in S.
Should I buy one?
All told, the CLS is still an impressive car – although certainly not one that's going to have things all its own way any more.
