Mercedes GLC review: six-cylinder GLC350d driven

# data.attributes.metatag[].attributes.content
A Mercedes-Benz GLC? What’s new? Nothing. The GLC has been around for a while now, and so has Mercedes’ 3.0-litre V6 diesel engine. They’re both very good in isolation, so one would assume that a GLC so equipped with said engine, rather than the usual four-cylinder diesel, would be a rather lovely thing. And is it?

A Mercedes-Benz GLC? What’s new?

Nothing. The GLC has been around for a while now, and so has Mercedes’ 3.0-litre V6 diesel engine. They’re both very good in isolation, so one would assume that a GLC so equipped with said engine, rather than the usual four-cylinder diesel, would be a rather lovely thing.

And is it?

Oh yes. More cylinders equals better in cars like this. Not that the four-cylinder isn't lovely in its own way, but more cylinders means more smoothness, more speed and a better noise. You’re looking at 254bhp, 0-62mph in 6.2secs, 148mph and an incredibly healthy 457lb ft of torque from just 1,600rpm. Not much more power, then, but just shy of 100lb ft more than you get in the torquiest four-cylinder GLC. That makes a difference - and because the nine-speed auto is seldom caught out (it operates as smoothly and unobtrusively as you'd hope. We think better than in four-cyl cars), there's power wherever and whenever you need it. Outright speed isn't its thing, but the way it builds is satisfying enough.

Four-cylinder diesels always sound strained, however much power they have. The six never does, it sounds expensive. Quieter and more refined than, say, a 3.0-litre Jaguar F-Pace, not least any four-cylinder you care to mention. Except maybe Mercedes’ own, which as of right now is only available in the E-Class...

So this is the GLC to have?

If you don’t fancy the GLC 43, and spending a few extra grand (around five of them) is of little concern, absolutely.
