Some interesting reading here as I'm looking to buy an Alfa in the coming months. I currently read 29.2 in my 6 year old (petrol 2.0L) 318i, the lowest it's ever been though it doesn't vary much, with a mixture of around 65% town and 35% motorway driving, and I'm not known for hanging around.
I would like the 3.2 159 but have been wondering if it's worth the extra fuel costs and have almost decided that I might be better off going for the 2.4, but reading some of the posts here I'm not so sure now!
TBH coolsociety, there is one major factor in deciding whether to buy any make/model of modern diesel. That's whether you do a lot of short journeys, which most (if not all) modern diesels do not like due to new technologies to reduce emissions.
If you don't do a lot of short journeys then you can choose either petrol or diesel but on a like for like basis (2.2 petrol vs 2.4 diesel) the Alfas return similar performance and economy. The real choice then is whether you get economy at the pump (which in the UK at the moemnt you don't) or if you care about the enviroment as a modern diesel produces less emissions. Fortunately for me the rest of Europe has significantly lower diesel than petrol costs (about £25 a tankful) and so I can save money and the enviroment without performance being reduced.
For reference here are some numbers for you :-
- Engine~~~~~~~~~MPH~~0-62~~~Combined Economy
- 2.2 JTS (185bhp)~~139~~~8.7~~~~31 mpg
- 2.4 JTDM (210bhp)~143~~~8.1~~~~42 mpg (this is quite optomistic and 35mpg is more realistic without driving like a granny)
- 3.2 V6 JTS(260bhp)~155~~~7.1~~~~26 mpg
All the above are the current (FWD) versions.
Although it is a little unfair to discuss modifications, you can easily add 45-50bhp to a 2.4 engine with a simple remap (costing approx £300) and get up to 3.2 standard power (they can also mod theirs though
). If you drive as you did before the remap you will still get the same mpg (or better some claim) but, who does when offered more power
There are some 'nightmare' mpg figures discussed on this forum but, I am so far unsure if they are all down to the car. It seems more likely (in a lot of cases) that driving style (heavy foot syndrome) and conditions (short journey driving, poor quality fuel etc) are the primary culprit. Do not be put off an Alfa diesel due to 50 or so people (including myself) being a little disappointed with the economy (expecting 45+ mpg
) and 4-5 with real problems out of the 1000's of owners.
Also as Fraser said, they are generally cheaper to insure and tax which with UK prices for tax/insurance is a nice bonus
