Saab 9-5 Sport Sedan 2.3 Turbo Aero Swift Challenger 540
Performance
Weight
The Saab 9-5 Sport Sedan 2.3 Turbo Aero with a Swift Challenger 540 with an actual weight of 1488 kg is in general a good match and suitable for all journeys on all kinds of roads.
The motor preformance of the Saab is in general very good. But the weight of the Swift with a normally distributed User Payload (200 kg in the caravan and 200 kg in the car including passengers), is heavy. Try to move luggage from the caravan to the car and drive not too fast. Remember to load your caravan correctly, insuring that the noseweight of the caravan is sufficient and the weight is distributed properly. But even so, a starting caravan driver is better off choosing a smaller and less heavy caravan!

Performance
The engine's performance is generally very good on flat roads (performance score to compare 269 points).
Speeds of 81 mph (131 km/h) to 86 mph (138 km/h) are often quite possible.
There is a lot of power at low engine speeds (score to compare 292 points).
Higher revs (1800 rpm) are usually not necessary on flat roads, under most circumstances.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 13.4 sec.
In the mountains the performance is generally very good (score to compare 320 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 22%.
On motorway inclines higher revs (2600 rpm) are needed.
A speed of 73 mph (118 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the Saab 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 (or B96) driving license.
Weight ratio between the laden caravan and the loaded car is 83%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 93%.
The risk of snaking at higher speeds, strong side winds and thoughtless driving is great. Even if the combination normally feels stable, the forces by deflection side to side are so great that it could be dangerous. Only if the driver has a lot of knowledge and experience in driving a caravan it should be safe to drive slowly. Proper and careful loading is essential! An electronic stability system in the car and / or on the caravan is definitely recommended.
Recommended noseweight is 80 kg.
Safe speed up to 50 mph (80 km/h).
Stability and safety score to compare is 112 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.
Proper and careful loading is essential!
It's a perfect match!
Influence of User Payload on stability
Weight distribution and noseweight are vital in obtaining a stable caravan.
