The Lexus IS 220d [wide ratio] with a Compass Corona 505 with an actual weight of 1500 kg is in general a good match and suitable for all journeys on all kinds of roads.
The motor preformance of the Lexus is in general good. But the weight of the Compass with a User Payload (188 kg in the caravan and 200 kg in the car including passengers), is quite heavy. Proper and careful loading is essential and don't drive too fast. Remember to load your caravan correctly, insuring that the noseweight of the caravan is sufficient and the weight is distributed properly!

Lexus IS 220d [wide ratio] Compass Corona 505
Actual Weights
Compass Corona 505: 1500 kg.
Lexus IS 220d [wide ratio]: 1860 kg.
Noseweight: 80 kg.
Actual weight ratio: 81%.
Performance
The engine's performance is generally good on flat roads (performance score to compare 237 points).
Speeds of 76 mph (122 km/h) to 81 mph (131 km/h) are often quite possible.
There is a lot of power at low engine speeds (score to compare 258 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 17.3 sec.
In the mountains the performance is generally very good (score to compare 277 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 19%.
On motorway inclines higher revs (2300 rpm) are needed.
A speed of 66 mph (107 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the Lexus is 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 81%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 90%.
The risk of snaking at higher speeds, strong side winds and thoughtless driving exist. 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 knowledge of and experience in driving a caravan it should be safe to drive. Proper and careful loading is essential! An electronic stability system in the car and / or on the caravan is recommended.
Recommended noseweight is 80 kg.
Safe speed up to 56 mph (90 km/h).
Stability and safety score to compare is 130 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 good.
Proper and careful loading is still important!
It's a perfect match!
Influence of User Payload on stability
Weight distribution and noseweight are vital in obtaining a stable caravan.
