Performance
The engine's performance is generally very good on flat roads (performance score to compare 303 points).
Speeds of 89 mph (143 km/h) to 93 mph (150 km/h) are often quite possible.
There is a lot of power at low engine speeds (score to compare 373 points).
Higher revs (2000 rpm) are usually not necessary on flat roads, under most circumstances.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 11.1 sec.
In the mountains the performance is generally very good (score to compare 365 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 81 mph (130 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 54%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 59%.
The chance of snaking is small even at higher speeds.
Recommended noseweight is 75 kg.
Stability and safety score to compare is 240 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.
