Verdict

The BMW X7 xDrive40i and the Caravan as an example of a laden weight of 1880 kg is an excellent combination for all journeys on all kinds of roads.

Weight

The chance of snaking is relatively small at normal speed, if the caravan is well loaded.

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 7th gear. In that case the engine runs approximately 2000 rpm, this gives maybe more noise than usually accustomed Maybe the engine is not running smoothly at low revs so it is better to shiftdown to the 6th gear, the engine runs in that case 2400 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 6th gear with 50 mph and even full throttle with 61 mph but maybe the engine is running better by somewhat more revs in the 5th gear). In the 4th gear the top speed is 89 mph (6269 rpm). Hill starts are possible on steep slopes, theoretical up to 44%, if the wheels have sufficient traction. Because the car does not have enough power at low revs, we recommend a gradient of more than 39% 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!
