Actual Weights
- Bailey Unicorn III Cadiz: 1537 kg.
- BMW X4 xDrive 40d: 2170 kg.
- Noseweight: 85 kg.
- Actual weight ratio: 71%.
Performance
- The engine's performance is generally very good on flat roads (performance score to compare 313 points).
- Speeds of 92 mph (149 km/h) to 96 mph (155 km/h) are often quite possible.
- There is a lot of power at low engine speeds (score to compare 435 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 8.6 sec.
- In the mountains the performance is generally very good (score to compare 410 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 86 mph (138 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.
- The caravan is too heavily loaded.
- Weight ratio between the laden caravan and the loaded car is 71%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 78%.
- There is a small chance of snaking at higher speeds, strong side winds and thoughtless driving. Even if the combination normally feels stable, the forces by deflection side to side are great at high speed. For drivers with knowledge of, and experience in driving a caravan it is safe to drive, but proper and careful loading is still important! An electronic stability system in the car and / or on the caravan is worth considering.
- Recommended noseweight is 85 kg.
- Safe speed up to 62 mph (100 km/h).
- Stability and safety score to compare is 172 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.
- If the caravan is well loaded 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.
Distribute the User Payload by yourself in the caravan and the car and then find out the stability rating of your loading configuration.
