Opel Astra 1.7 CDTi [6MT] Eriba Familia 320
Actual Weights
Eriba Familia 320: 900 kg.
Opel Astra 1.7 CDTi [6MT]: 1565 kg.
Noseweight: 60 kg.
Actual weight ratio: 58%.
Performance
The engine's performance is generally good on flat roads (performance score to compare 232 points).
Speeds of 76 mph (122 km/h) to 81 mph (131 km/h) are often quite possible.
There is sufficient power at low engine speeds (score to compare 193 points).
Slightly higher revs (1800 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 19.1 sec.
In the mountains the performance is generally very good (score to compare 258 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 (2700 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 58%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 66%.
The chance of snaking is small even at higher speeds.
Recommended noseweight is 60 kg.
Stability and safety score to compare is 248 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.
