Performance
The engine's performance is generally good on flat roads (performance score to compare 247 points).
Speeds of 78 mph (125 km/h) to 83 mph (134 km/h) are often quite possible.
There is sufficient power at low engine speeds (score to compare 189 points).
Slightly higher revs (2000 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 16.4 sec.
In the mountains the performance is generally very good (score to compare 291 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 (3100 rpm) are needed.
A speed of 69 mph (111 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the Opel 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 63%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 70%.
The chance of snaking is small even at higher speeds.
Recommended noseweight is 70 kg.
Stability and safety score to compare is 213 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.
