We do not recommend towing a caravan that is heavier than 1650 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 X3 sDrive 20i 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 good. And also the weight of the Caravan with a User Payload (-200 kg in the caravan and 200 kg in the car including passengers), is very good.

BMW X3 sDrive 20i: 1935 kg.
Noseweight: 70 kg.
Actual weight ratio: 65%.
Performance
The engine's performance is generally very good on flat roads (performance score to compare 253 points).
Speeds of 79 mph (127 km/h) to 84 mph (135 km/h) are often quite possible.
There is sufficient power at low engine speeds (score to compare 196 points).
Slightly higher revs (2000 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 15.9 sec.
In the mountains the performance is generally very good (score to compare 305 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 21%.
On motorway inclines higher revs (3400 rpm) are needed.
A speed of 69 mph (112 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 (or B96) driving license.
Weight ratio between the laden caravan and the loaded car is 65%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 72%.
The chance of snaking is small even at higher speeds.
Recommended noseweight is 70 kg.
Stability and safety score to compare is 205 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 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.
