Lastly have any of you owned a BMW 3 series and IS250? If so can you adivse on how they both compare? I just love the IS250 but the only thing that appeals to me about the BMW 3 series is the fact it comes with an auto gearbox in diesel. Btw why on earth there is no auto option in the IS220d?
I'm surprised you consider the IS250 thirsty. I do very local mileage, 5 miles to work and weekly supermarket trip of 30 miles and average 29mpg this Winter (only had car since November). I expect the mpg to improve somewhat through the Summer months.
Can't comment on the BMW its just a make that's never interested me. For a 2.5ltr petrol the IS is very good on fuel. I can only think you have read the usual mag reviews that slate Lexus on anything they can find. They probably compared it to a 2 ltr diesel.
Fuel mpg average is about 29-34 on mine. Best ever close to 40mpg (bit exceptional I'll grant) and if I get a little silly it can be 25-26. But its great fun doing that. The paddles are great for a bit of fun driving. Brill for overtaking.
Every single person that's been in it likes it!! My boss dropped off his Aston Martin to be serviced this morning. So I picked him up and now he wants to borrow it this afternoon!!! Really liked what he saw/felt. Dammit.
Back to the original question, I have now done 57,000 miles over 5 years in my IS250 and my driving is a mixture of around town and motorway driving. My highest mpg is 41 but I also get 37 every so often. My worst is 24 when I've driven around London all day. These figures are my calculated mpg on fill ups.
Id second all the other comments here. My MPG averages around 29-30, but can get 32 If I make a bit of an effort (gentle right foot, good anticipation) and thats with very few motorway miles.Do the usual stuff, such as keep on top off correct tyre pressures etc. and these figures are fairly easy to see.
The main difference between the two in my experience is the interior material and build quality. Better on the Lexus. Ride was also harsh on the BMW due to run flat tyres being standard. The BMW has better cabin space. Im 6'2 and sit comfortably in the Lexus but the rear is cramped. Overall ownership experience I have to say goes to the Lexus. And the BM loses its special feeling quick as they are so common.
What to look out for - not an exhaustive list but the spark plugs need changing at 60k miles service and its expensive (500-600 at main dealer), the brake calipers are prone to seizing up. Seach this forum for lots of good info.
You dont say what age\mileage of car you looking at but BM diesels dont like big mileages. My neighbours have a 120d and 320d and both needed expensive turbo rebuilds before 80k miles. The 320d needed two come to think of it.
I travel 50 miles a day going to work and back, I travel on a variety of roads and in traffic and my tank average always sits between 31 and 32 mpg, for a V6 2.5l I think that is more than acceptable, I used to have a 520d till the turbo blew................ouch not cheap!
UK magazines and sites heavily favour their sponsors. It's a good idea to look at reviews from the US as well to get a better idea of reality. UK reviewers also seem obsessed with how well a car handles at the limit / can they drift it, but never mention how it deals with poor road conditions & potholes. Quite frankly they're embarrassing.
That usually entails being stuck in lots of traffic and driving on potholed roads so yes, how good your car is probably depends on how it keeps you calm and relaxed in these situations. The Lexus with its smooth auto box and relaxing ride certainly covers all the really important bases.
I also agree with what most people have said here. To me the BMW just looks too ordinary (maybe because it is so common) and dull/dated from inside whereas the IS250 just grabs your attention straight away.
Also have to agree with the point on the favourable reviews BMW's tend to get. The main point that seems to get emphasised all the time is the handling of the BMW's when pushed to the limits. I am looking for a car to drive in my every day life not one that I will be using for rally driving. To me confort and economy are more important than how the car handles at high speeds around tight bends. The level of equipment you get with the IS250 is just miles better than what you get with a BMW 3 series. For example you will struggle to find one with electric seats whereas this comes pretty much as standard with the IS250.
Yes the IS250 wouldnt live with a 3 series pushed to the limit on a track - but who cares? Its a fantastic car in the way we all use them. Look at Clarksons shocking RCF review on top gear - couple of drifts on an disused airfield and dismisses it as useless. On the limit handling is something some people want to to know about and makes for good slow-mo atmospheric tv pictures - but its not the basis on which 99% people actually buy or use cars.
I live in MK too and have run several IS models, I had the 220d new in 2006, an IS250 f sport in 2010 and just changed to a new IS250 Premier. Even running on the dual carriageways daily I can't get past 29 mpg yet. I've only done one proper motorway run, and that didn't help due to the fact that it was the first chance to really open it up. I'd expect that with a light right foot cruising on a clear motorway, I'd get into the low 30s per gallon.
My overall average is 33 mpg over 80000 miles mixed driving, more in summer less in winter. That's actual rather than what the instrumentation says as it tends to read 3 mpg over but given the cars weight and I use Sainsbury's standard unleaded I'm not going to grumble.
I think realistically that is pretty good for a small V6 engine. Ive averaged not much better in diesels and been made to feel satisfied that it must be good because its a diesel. Mines is an 08 with 113k and it drives like its never turned a wheel. Fantastic thing
Where did you read that IS250 has bad fuel economy as well bad compared to what 1.0l Fiesta? My late 250 which had nearly 200k miles was still fairly fuel efficient (more more efficient than my new RC). My all time average MPG was 28.3 over 70k miles, which I consider very decent.. and I was hammering it all the time.
