2019 BMW 330d verdict

With a new six-cylinder diesel engine under the bonnet, the BMW 330d promises pace with palatable running costs...

2019 BMW 330d pan

There’s no doubt the 330d’s straight-six diesel is the best engine we’ve yet experienced in the 3 Series. Not only is it rapid and refined, but we also saw well over 40mpg on the trip computer without too much effort at all. For a 3.0-litre engine, that’s not bad at all.

But let's be sensible for a second. The 320d isn’t exactly what you’d call slow, emits up to 20g/km less CO2 and is nearly £3000 cheaper, assuming you want an automatic gearbox. Furthermore, no standard 320d breaks the £40,000 mark, while all 330ds do, increasing your yearly car tax. That’s enough to keep the 320d as our recommended version, even if we’d be sorely tempted by the 330d.
