Number of useful calculations


The Lexus RX450h and the Caravan as an example of a laden weight of 1710 kg is an excellent combination for all journeys on all kinds of roads.


The chance of snaking is relatively small at normal speed, if the caravan is well loaded.

Flat roads

The performances of the engine of this outfit are in general very good. Under all conditions on motorways it is possible to drive with 60 mph in the 8th gear. In that case the engine runs approximately 1800 rpm. Maybe the engine is not running smoothly at low revs so it is better to shiftdown to the 7th gear, the engine runs in that case 2600 rpm (witch is maybe more noisily than usually accustomed). In a headwind or for example on a crossover there is no need to downshift immediately.


On most motorways inclines (1:20) driving is easily possible in the 7th gear with 50 mph and even full throttle with 69 mph but maybe the engine is running better by somewhat more revs in the 6th gear). In the 6th gear the top speed is 84 mph (4978 rpm). Hill starts are possible on steep slopes, theoretical up to 48%, if the wheels have sufficient traction. Because the car does not have enough power at low revs, we recommend a gradient of more than 46% not to drive.

Attention: This car can easily drive much faster with the caravan than is safe. So always keep an eye on your speed!

The Lexus towing a Abbey GTS Vogue 417 (1399) kg reviewed by Paul:

Have been towing with the Lexus RX450h now for a couple of years and am very happy with it. I was a little apprehensive at first due to the car being a hybrid but it doesn't seem to affect things too much to be honest. It will pull the caravan at 40mph on electric only when conditions allow. Nowhere near as torquey as a my previous towcar (Volvo XC60) but copes just as well. Just don't expect it to keep up with the big diesels like land rovers etc up the hills. On a recent trip to the New Forest, I managed to achieve a frankly unbelievable 41mpg!!! This was with 2 adults, 2 children and a weeks worth of food, clothing etc inside the caravan. A total of 240 miles at a modest 50mph, mainly on cruise control. The mpg indicator on this car is usually pretty much accurate so I can only assume this was correct. One down side I would like to mention is the very low towball limit of 80kg. The car is capable of towing 2000kg but I find it hard to believe you could manage to tow a twin axle caravan of this weight and still get the towball weight down to 80kg. I would love to be told different if anyone has managed this. Also, I think the rear suspension is a little on the soft side to cope well with the weight transfer from caravan to car although this is obviously fine on smooth roads. To summarise, anyone that's thinking about buying one of these and using it as a towcar, I'd say just go for it. I don't think you would be disappointed.
