Audi Q7 3.0 TDI Bailey Pegasus 624
Actual Weights
Bailey Pegasus 624: 1638 kg.
Audi Q7 3.0 TDI: 2595 kg.
Noseweight: 90 kg.
Actual weight ratio: 63%.
Performance
The engine's performance is generally very good on flat roads (performance score to compare 271 points).
Speeds of 83 mph (134 km/h) to 88 mph (142 km/h) are often quite possible.
There is a lot of power at low engine speeds (score to compare 335 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 15.5 sec.
In the mountains the performance is generally very good (score to compare 329 points).
No problems are to be expected on steep mountain roads (up to 25%). Not even on Hill starts.
On motorway inclines hardly any higher revs are needed.
A speed of 73 mph (118 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the Audi 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 driving license.
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 68%.
The chance of snaking is relatively small at normal speed, if the caravan is well loaded.
Recommended noseweight is 90 kg.
Safe speed up to 62 mph (100 km/h).
Stability and safety score to compare is 200 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.
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.
