The BMW 528i with a Ace Jubilee Envoy with an actual weight of 1310 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 good. And also the weight of the Ace with a User Payload (198 kg in the caravan and 200 kg in the car including passengers), is pretty good.

Actual weight ratio: 75%.
Performance
The engine's performance is generally good on flat roads (performance score to compare 240 points).
Speeds of 76 mph (122 km/h) to 81 mph (130 km/h) are often quite possible.
There is more than enough power at low engine speeds (score to compare 209 points).
Slightly higher revs (2100 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 16.2 sec.
In the mountains the performance is generally very good (score to compare 278 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 17%.
On motorway inclines higher revs (3100 rpm) are needed.
A speed of 68 mph (109 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 75%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 85%.
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 75 kg.
Safe speed up to 62 mph (100 km/h).
Stability and safety score to compare is 161 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.
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.
