66 MPG ????

I'm doing a lot of short local runs at the moment and getting 30.9 mpg

Bill is correct, mine is a NX 450h+. The original post in the NX forum hopefully explains it. For the 1,800 miles on the odometer, I have put in fuel (around 125ltrs) that equates to 66mpg but I have also charged up the 18Kw Battery several times and that has had a cost. However, as you can imagine for a return trip from North Scotland to the mid-West coast of Wales, a significant amount of time was spent on motorways and 'A' roads with the ICE doing the work. The main thing is that I am very happy 🙂

Coming back from Bristol to Reading one evening last week, there was an issue on the M4.

Not being in a hurry, I decided to take the A420 out of Bristol to Chippenham, and then the A4 through Calne, Avebury, Marlborough, Hungerford, Newbury, Thatcham and then Reading.

This wasn’t a quick journey - M4 usually takes about 75 minutes, and this took two hours…but, with an average speed of 40-50mph rather than 70mph, I managed a fuel economy I never thought I’d see on an RX. 

42.3mpg shown. Sometimes it’s nice to take the ‘road less travelled.’  It was a lovely drive. Just not the best if you’re in a hurry!

At the moment I tend to do short miles, say between 5 and 12 miles.  This is dropping my mpg but to be honest, I save more by the fact I am driving less.  I do think its more economical on longer runs and still have to take it on the motorway for a run.  I just haven't had the need yet.

In this season, without needing air conditioner, my average is about 39 mpg.

Interesting read as yet again, I'm tempted into an RX. Currently using a BM... cough...W X3 2.0d which is returning around 42-45mpg. Not bad considering the performance it provides etc. There is however one factor to consider when moving from a diesel chariot to a petrol driven one nowadays. The gap between the cost/litre of diesel compared to unleaded has widened, to a point where if I move across to a RX, the cost of fuel per month for me is around the same, just using a green pump and not the black one.

A few temptations out there at the moment. Looking at post 2019 so I get Android/Apple car play, other than that, best spec and colour I can find. I have my first drive in an RX when I go to the dealer next week. Q the drum roll!

Good luck! I daren't try a Gen 4 RX,as I know it'd spoil the older model that I currently have and want to keep for a good few years yet.

Try and get as long a test drive as you can. Even then I think it's the sort of car where you might not immediately 'get' it. Takes a while to learn to how to use the hybrid to its best advantage, be that for reasonable economy or luxurious, near-silent wafting (or both).

I reckon I'm using mine for the optimum journeys at present. About a 40-mile trip so it's thoroughly warmed-up, much of it on a 50mph A-road when I can roll along with minimal work from the petrol engine and a good chunk in town (with some long downhill stretches to keep the charge up). I'm getting an indicated 38+ MPG, but still enjoying the V6 every so often.

I should add that even though its not a Lexus, we have had a CHR hybrid and now a Mazda2 Hybrid for the past 4 years. I agree, to get the best out of it, you need a different style to driving, it makes you plan ahead, view the road, the traffic and accelerate/decelrate to optimise the car.

This is one of the main reasons Im looking to Lexus. Luxurious, effortless and reliable, what more do you want?
