Opel Signum 1.9 CDTi: 1936 kg.
Noseweight: 75 kg.
Actual weight ratio: 66%.
Performance
The engine's performance is generally good on flat roads (performance score to compare 228 points).
Speeds of 74 mph (120 km/h) to 80 mph (129 km/h) are often quite possible.
There is more than enough power at low engine speeds (score to compare 204 points).
Slightly higher revs (1700 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 18.7 sec.
In the mountains the performance is generally very good (score to compare 260 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 (2800 rpm) are needed.
A speed of 65 mph (105 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 66%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 74%.
The chance of snaking is small even at higher speeds.
Recommended noseweight is 75 kg.
Stability and safety score to compare is 201 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 fairly 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.
