We do not recommend towing a caravan that is heavier than 1750 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 Touring 540i xDrive 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 (-300 kg in the caravan and 200 kg in the car including passengers), is very good.

Performance
The engine's performance is generally very good on flat roads (performance score to compare 310 points).
Speeds of 91 mph (146 km/h) to 94 mph (152 km/h) are often quite possible.
There is a lot of power at low engine speeds (score to compare 361 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 8.6 sec.
In the mountains the performance is generally very good (score to compare 399 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 84 mph (136 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 59%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 65%.
The chance of snaking is small even at higher speeds.
Recommended noseweight is 70 kg.
Stability and safety score to compare is 227 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.
