The best-selling BMW 4 Series should, arguably, be a BMW 3 Series

The BMW 4 Series range has recently been updated, and BMW has now revealed that the most successful model is actually a four-door – the BMW 4-Series Gran Coupe.

The BMW Gran Coupe – which you can have as either a 4 Series Gran Coupe or 6 Series Gran Coupe – is a bit of an odd car; it’s a coupe but it’s a four door.

We confess we really didn’t see what the point of it was, at least we didn’t until we reviewed the 6-Series Gran Coupe a while ago. And then we discovered it’s probably the pick of the range.

And it seems buyers are starting to think the same way, as BMW reveal that the best-selling 4-Series isn’t, as you might expect, the regular 4-Series Coupe – or even the 4-Series Convertible – but is in fact the Gran Coupe.

The 4 Series Gran Coupe now accounts for 54 per cent of all 4 Series cars sold, easily outselling the two-door Coupe and the convertible, as buyers realise it’s just a very good car; better looking, more practical and nicer to drive than the 3 Series saloon. It’s proving a proper success story.

So despite rumours which have persisted since the 4 Series Gran Coupe was launched that it was a bit of a Dodo, and BMW were looking to drop it in the next generation, it now seems clear the opposite is true.

And if we’d had our thinking caps properly on, we should have realised that when BMW extended the Gran Coupe range to add a new entry-level 418d when they refreshed the range in January.

The best-selling BMW 4 Series is really a BMW 3 Series.
