Looking at RX400h

[Roytonian]

Good afternoon everyone, new to the forum and thanks for accepting me. 

I’m currently running a Jaguar S-Type diesel, and, due to a dodgy left knee, finding getting out of it more and more painful. So, in an effort to retain some form of premiumness in my car choice, and improve egress, I’m looking at buying an RX400h. 

I’m sure these have been asked before, and if there’s a buying guide sticky within the group I’d loved to be directed towards it.

Currently, I’m getting close to 50mpg on a 70mph motorway run, but probably only low 20’s around town, what could I expect from the Lexus?

i know they have a reputation for being bulletproof, mechanically, but is there anything I need to look out for, either mechanically, electrically or bodily? 

Thank you.

Hi Michael,

As regards MPG no doubt owners of the RX400h willt give you a more individualized range of figures but from what I have read the RX400 should better the 20mpg you get from your Jag about town but you wont get anything like 50mpg on a motorway.  The best I have achieved with my RX450h on a motorway was 37mpg and this is a tad more economical than the RX400h.  There again results would vary a lot depending with speed, giving better results where there is a 50mph restriction than 70mph. Really motorway economy is not the RX forte. The RXmodels are heavy and not as aerodynamic as most saloons so fuel consumption more affected by this too.

RX models have a good reputation for reliability but when something goes wrong the cost can be very high as can be cost of servicing.  They hold their price well compared to the competition and are certainly comfortable, the latter being the main reason why I bought one.  The RX450h is more refined and a better car if you could extend to one, perhaps with more miles on it.
