Porsche Cayenne S aut.: 2545 kg.
Noseweight: 100 kg.
Actual weight ratio: 76%.
Performance
The engine's performance is generally very good on flat roads (performance score to compare 296 points).
Speeds of 87 mph (141 km/h) to 92 mph (148 km/h) are often quite possible.
There is a lot of power at low engine speeds (score to compare 342 points).
Higher revs (2000 rpm) are usually not necessary on flat roads, under most circumstances.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 12.7 sec.
In the mountains the performance is generally very good (score to compare 348 points).
No problems are to be expected on steep mountain roads (up to 25%). Not even on Hill starts.
On motorway inclines higher revs (2600 rpm) are needed.
A speed of 78 mph (126 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the Porsche 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 76%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is INF%.
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 100 kg.
Safe speed up to 62 mph (100 km/h).
Stability and safety score to compare is 159 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.
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.
