Advice with maximum weight
We do not recommend towing a caravan that is heavier than 1500 kg kg with this Lexus.
In this advice we assume an average caravan with a weight of 1500 kg. Remember that the exact performance depends on the chosen caravan and that air resistance and dimensions have an influence.
 Performance | |  Weight |
The Lexus GS 450h with a Caravan as an example 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 very good. And also the weight of the Caravan with a normally distributed User Payload (200 kg in the caravan and 200 kg in the car including passengers), is pretty good.

Attention
The Lexus is a hybrid car. The calculated performance depends on the amount of power available in the battery. The advice and performance are based on average use where there is still a small amount of power in the battery.

Actual Weights
- Caravan as an example: 1500 kg.
- Lexus GS 450h: 2095 kg.
- Noseweight: 80 kg.
- Actual weight ratio: 72%.
Performance
- The engine's performance is generally very good on flat roads (performance score to compare 299 points).
- Speeds of 87 mph (140 km/h) to 91 mph (147 km/h) are often quite possible.
- There is a lot of power at low engine speeds (score to compare 313 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 10.5 sec.
- In the mountains the performance is generally very good (score to compare 358 points).
- No problems are to be expected on steep mountain roads (up to 25%). Not even on Hill starts.
- On motorway inclines higher revs (2900 rpm) are needed.
- A speed of 80 mph (129 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 72%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 79%.
- 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 80 kg.
- Safe speed up to 62 mph (100 km/h).
- Stability and safety score to compare is 172 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.
Distribute the User Payload by yourself in the caravan and the car and then find out the stability rating of your loading configuration.
