BMW 520d aut. Lunar Stellar
Actual Weights
Lunar Stellar: 1215 kg.
BMW 520d aut.: 1820 kg.
Noseweight: 70 kg.
Actual weight ratio: 67%.
Performance
The engine's performance is generally good on flat roads (performance score to compare 245 points).
Speeds of 76 mph (123 km/h) to 81 mph (131 km/h) are often quite possible.
There is more than enough power at low engine speeds (score to compare 233 points).
Higher revs (1600 rpm) are usually not necessary on flat roads, under most circumstances.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 15.1 sec.
In the mountains the performance is generally very good (score to compare 311 points).
No problems are to be expected on steep mountain roads (up to 25%). Not even on Hill starts.
On motorway inclines higher revs (2500 rpm) are needed.
A speed of 69 mph (111 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 67%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 76%.
The chance of snaking is small even at higher speeds.
Recommended noseweight is 70 kg.
Stability and safety score to compare is 200 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.
