The BMW X3 is essentially a shrunken version of the firm's X5. It's available with a choice of three diesel engines - a 2.0-litre four-cylinder and two 3.0-litre six-cylinder units - and all offer impressive performance combined with low running costs. The range topping xDrive35d is very powerful. It produces 313bhp and 630Nm of torque, which gives it a 0-62mph time of 5.8 seconds - which is faster than some sports cars. The entry-level xDrive20d, on the ohter hand, returns 50mpg and emissions of 149g/km, so it's relatively cheap to run. The X3's interior is beautifully made and very comfortable on longer journeys, and the car also has a huge boot. All X3s feel sporty, even when fitted with the excellent eight-speed automatic transmission, and are very easy to drive. Entry-level SE models are reasonably well equipped, including leather seats, front and rear parking sensors and air conditioning. M Sport models have even more kit, but the larger alloy wheels spoil the car's comfort.
