For This has more muscle than an army of elements. In fact, it's so quick there's little reason to choose one of the petrol models instead. Even so, economy is impressive.

Against The 30d is not that much slower, yet costs less to buy and fuel. It will also be cheaper to run as a company car. Petrol versions sound better when accelerating hard.

This version of the X6 is an impressive achievement. Stylish and fast, it's good enough to convert the most ardent fan of petrol power to the diesel cause.

Buyer's notes

Target Price team says:

Any X6 demands certain compromises. There are just the four seats, and the boot is small, for example. If that doesn’t put you off, though, there’s a lot to enjoy.

For starters, there’s no such thing as a slow X6. Even the smallest diesel, the 30d, shifts with real vigour, although it can sound a little gruff when really pushed.

Stepping up to the 40d means more of the same, only more so, with only a slight penalty at the pumps. You’ll be stopping to fill up rather more often in either of the petrols. The 35i strikes the more sensible balance between performance, price and economy, but the 50i is savagely quick but expensive.

There’s only one trim level across all models, and it’s well equipped as standard. The worthwhile BMW Service Inclusive package covers servicing costs for five years/60,000 miles for a one-off payment. It’s transferable to future owners which helps keep resale values healthy.
