We do not recommend towing a caravan that is heavier than 1500 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 418i GranCoupe 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 fairly good. And also the weight of the Caravan with a User Payload (-50 kg in the caravan and 200 kg in the car including passengers), is very good.

BMW 418i GranCoupe Caravan as an example
Actual Weights
Caravan as an example: 1250 kg.
BMW 418i GranCoupe: 1785 kg.
Noseweight: 70 kg.
Actual weight ratio: 70%.
Performance
The engine's performance is generally good on flat roads (performance score to compare 225 points).
Speeds of 73 mph (118 km/h) to 79 mph (127 km/h) are often quite possible.
There is sufficient power at low engine speeds (score to compare 153 points).
Slightly higher revs (2300 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 17.9 sec.
In the mountains the performance is generally very good (score to compare 259 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 18%.
On motorway inclines higher revs (3900 rpm) are needed.
A speed of 64 mph (104 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, a B driving license is enough.
Weight ratio between the laden caravan and the loaded car is 70%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 79%.
The chance of snaking is relatively small at normal speed, if the caravan is well loaded.
Recommended noseweight is 70 kg.
Safe speed up to 62 mph (100 km/h).
Stability and safety score to compare is 184 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 fairly 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.
