Hi, I've had my 05-plate 400h SE-L for slightly above 6 months now. I have driven it in both winter and summer and on most occasions done brim-to-brim fill-up based comparisons (the OBC has consistently overstated the truth by 2mpg). The best I've managed so far is 34mpg. The worst (27mpg) was during the February snow period when the car was driving mostly on petrol at very slow speeds. The more you get the car to coast, the better the mpg, as while coasting the car doesn't run on the engine. Also, the car runs subtantially longer on the battery alone (providing you keep a light right foot) once the engine has warmed up sufficiently. On open country roads (40-50mph roads) I tend to use the cruise control quite a lot. That improves the mpg quite dramatically. Cruise-control mpg is the best in the 50-70mph range. I have seen no evidence of the mpg being better at above 70mph speeds in motorway driving. But then, mine is only one of the hundreds of 400h's cruising the roads of the UK.

That's right.We're all brain washed morons that buy,and like,RX400h's. I am glad you keep chipping in,telling us how flawed we are in the choice of vehicle we have made. The RX replacement is due out next year,and I heard that such is the demand for current RX's in the UK that they aren't even going to bring out the hybrid RX due to lack of demand,all the RX's in the UK will be standard petrol models.(Or have I got that the wrong way round?) From what I've read, they're actually phasing out the petrol RX because there's little demand for it in the UK. The next gen RX is likely to be only hybrid. Frankly, I am astonished at the extent of dislike for the 400h some people have developed.

I've had my 2005 reg 400h SE-L for slightly over a month and I've done upwards of 1000 miles in it already. IMHO, the car is clearly a cut above its peers, especially judging by the combination of performance, comfort and economy. On the motorway, it's more than a match for the above-average crowd. It's fast and never lets you down when you have to complete a tricky overtaking manoeuvre. In town and country roads, its fuel economy is exceptional (I've never dropped below 30 mpg and the max I've returned is 35 mpg). Even on the motorway, providing you use the cruise control regularly, you'll return an average of around 31 mpg. The car is extremely roomy and comfortable and quite easy to drive. Also, for a car this size, the handling is quite good.

Hi all, I am a new member. I don't actually own a 400h, but I borrowed it for 24 hours from the local dealer. I was quite impressed to get 35mpg in town driving and 31mpg on the motorway. Some people claim to have got 40+mpg, which sounds a bit far fetched, but even so, I think the 33mpg that I got was quite exceptional. And this was in a brand new car. I understand from the posts elsewhere that the fuel economy improves quite substantially after the first 10000miles, as the V6 starts kicking in around 40mph rather than 25mph for a new car.
