We do not recommend towing a caravan that is heavier than 2220 kg kg with this BMW.
In this advice we assume an average caravan with a weight of 1250 kg. Remember that the exact performance depends on the chosen caravan and that air resistance and dimensions have an influence.
Performance
Weight
The BMW X7 xDrive40i with a Caravan as an example with an actual weight of 1250 kg is in general a good match and suitable for all journeys on all kinds of roads.
The motor preformance of the BMW is in general very good. And also the weight of the Caravan with a User Payload (-770 kg in the caravan and 200 kg in the car including passengers), is very good.

Actual Weights
Caravan as an example: 1250 kg.
BMW X7 xDrive40i: 2595 kg.
Noseweight: 70 kg.
Actual weight ratio: 48%.
Performance
The engine's performance is generally very good on flat roads (performance score to compare 313 points).
Speeds of 92 mph (149 km/h) to 96 mph (155 km/h) are often quite possible.
There is a lot of power at low engine speeds (score to compare 363 points).
Higher revs (1800 rpm) are usually not necessary on flat roads, under most circumstances.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 9.1 sec.
In the mountains the performance is generally very good (score to compare 398 points).
No problems are to be expected on steep mountain roads (up to 30%). Not even on Hill starts.
On motorway inclines hardly any higher revs are needed.
A speed of 86 mph (138 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the BMW is more than sufficient (check this in your vehicle documents).
If you passed your driving test after 1 January 1997, you will need a B+E driving license.
Weight ratio between the laden caravan and the loaded car is 48%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 52%.
The chance of snaking is small even at higher speeds.
Recommended noseweight is 70 kg.
Stability and safety score to compare is 270 points.
If the caravan starts to snake you should reduce your speed and slow down directly! Lift your feet off the accelerator and brake gradually. Hold the steering wheel into a fixed position.
Conclusion
Performance is very good.
Safe driving is possible.
It's a perfect match!
Influence of User Payload on stability
Weight distribution and noseweight are vital in obtaining a stable caravan.
