Verdict

The BMW X3 xDrive M40d and the Caravan as an example of a laden weight of 550 kg is an excellent combination for all journeys on all kinds of roads.

Weight

The chance of snaking is small even at higher speeds.

Flat roads

The performances of the engine of this outfit are in general very good. Under all conditions on motorways it is possible to drive with 60 mph in the 8th gear. In that case the engine runs approximately 1300 rpm. Maybe the engine is not running smoothly at low revs so it is better to shiftdown to the 7th gear, the engine runs in that case 1700 rpm (witch is maybe more noisily than usually accustomed). In a headwind or for example on a crossover there is no need to downshift immediately.

Mountains

On most motorways inclines (1:20) driving is easily possible in the 7th gear with 50 mph and even full throttle with 89 mph but maybe the engine is running better by somewhat more revs in the 6th gear). In the 6th gear the top speed is 104 mph (3524 rpm). Hill starts are possible on steep slopes, theoretical up to 94%, if the wheels have sufficient traction. Because the car does not have enough power at low revs, we recommend a gradient of more than 72% not to drive.

Attention: This car can easily drive much faster with the caravan than is safe. So always keep an eye on your speed!
