I am amazed at the reports of towing with a Lexus RX 450. I have just returned home to Kent from Dorset, pulling my1865kg Coachman with my 2016 RX h F Sport. Because the car has a ctv gearbox, it can’t change down, so when you apply more power it just seems to make more noise, and putting it into sport makes it worse, it just revs harder for very little result. Fuel consumption dropped to 19 mpg. As a luxury car my 450 RX f sport is excellent, and driven carefully returns mid 30’s mpg, but as an suv that has to work for a living, it is totally out classed by my old Range Rover sport 3L diesel. I can’t believe nobody else has reported this.
