There is a lot of power at low engine speeds (score to compare 266 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 16.2 sec.
In the mountains the performance is generally very good (score to compare 303 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 24%.
On motorway inclines higher revs (2200 rpm) are needed.
A speed of 68 mph (109 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the Lexus 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 70%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 78%.
The chance of snaking is relatively small at normal speed, if the caravan is well loaded.
Recommended noseweight is 75 kg.
Safe speed up to 62 mph (100 km/h).
Stability and safety score to compare is 185 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.
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.
