Lexus Estate RX 450h in Towcar Talk Posted November 5 36 minutes ago, Black Grouse said: I believe contributor Lutz used one for a while. Yes, I towed an 1800kg single axle with an RX400h for over 6 years. It was a nice car. The biggest disadvantage was its relative thirst when towing, but solo and particular in town traffic when running a lot on electric only, it returned very respectable fuel consumption figures for its size and weight. A couple of further negative comments I would make about the RX400h, but I'm told they were resolved for the later RX450h, were the much too small starter battery (there simply wasn't enough space under the bonnet for a larger one) and its torque sensitive steering, especially when pulling away from traffic lights with the caravan on the back. (The starter battery was identical to the one in the Nissan Micra). Apart from that it was a very refined car and to a certain extent I'm sorry I parted with it.
