335i v 330d - real world fuel economy ?
Discussion
At the beginning of the year I had to replace my company car (a 530xd) and ended up going for a 330xd. I have a daily commute of around 60 miles plus do a few long trips a year (mainly north from Switzerland to the UK for visits or south to France/Spain for holidays). I'm very happy with the 330xd and principally chose it because of economy reasons, otherwise I would have gone for the 335xi which we have here in Switzerland. In the 330xd I average around 35 mpg, which doesn't seem that great given that 90-95% of the time I am on the motorway (although perhaps going a bit slower might help...)
For those owning 335is - what sort of average mpg are you getting (ie did I make the wrong choice...)?

I seem to be getting fewer mpg than others. I wonder how much the autobox and 4-wheeldrive is having an impact. I used to get pretty much the same with the 530xd but thought that with the 330xd being a bit smaller and a bit lighter the mpg would improve. It is better but only marginally.
Still...it seems to be significantly better than a 335i would get.

I have a 335i (07 msport model so still twin turbo) and get 25.9mpg. I mainly do M/way driving and usual town driving
That is always what my average would end up at. If I reset it on the motorway doing 75mph I would see 36/37 and around 34 by the end of the journey, but would end up back at 25.9 after a week or so of driving. 25.6 average on my 2007 manual E92 335i ( before and after remap ); mostly very short journeys of less than 3 miles to and from work; the temp gauge never moves. Long trips yield 34~35 when driving at tedious DC/MWay speeds and 31~32 at normal pace. 335i is very thirsty in town unless you change up early and use the torque.
I was hoping for better based upon the EU combined figures and the fact my E36 M3 EVO achieved 27.7 using the same driving mix.

I think it's possible to get nearly 40mpg from my 335i if I at 60mph constantly on the Motorway and didn't touch the accelerator. In real life the engine sounds so good I often keep her in 2nd gear at 5-6krpm just to hear the straight six at work...this obviously means a mpg of <20 on most runs I do, but the smile it brings to my face is priceless

Who did your re-map? I've been considering this for a while and trying not to get bogged down in debates over tuners. Had a run in a car thats had teh superchip map and was noticably different. Are you happy with yours (Sorry to hijack op) I was hoping for better based upon the EU combined figures and the fact my E36 M3 EVO achieved 27.7 using the same driving mix.

Its an Evolve map on mine http://evolveautomotive.com/e9x-engine-ecu_726/335... and I'm very happy with the results 
. 250 lb/ft per ton means it gathers speed very quickly in the mid range now; it needs better brakes tbh.As a general observation I'm surprised that the 335i doesn't manage to do better than a lot of owners on this thread seem to be experiencing. My E46 M3 CS is generally around 25-26mpg and, while that doesn't include much city driving or short runs, it doesn't involve sticking to 70mph on the motorway either! Even the early versions of the 335i are meant to be around 5-6mpg better than my M3 and the lastest cars with the N55 engine are in theory supposed to be more like 10mpg better; therefore, unless my driving included a lot of short runs and/or stop-start work I have to say I'd be very disappointed with anything less than 30mpg out of a 335i. Less than 20mpg seems plain ridiculous - I suspect you'd have to drive an E92 M3 quite hard to get down to that and in truth it's more E60 M5 territory!

I think its because the two small turbos are always on the go i.e working from very low rpms; the 335i's continuous mpg display makes for sobering reading when the car is cold or when you're driving in town. Single figure mpg is common even with a light throttle 
and it certainly encourages you to change up sooner than usual. It gets much better at 'normal' M-Way speeds on long runs; mine usually returns 32~33 mpg. Edited by Crackie on Wednesday 24th August 14:59
27.7mpg on my 335i convertible using normal unleaded - never seems to change and I do a mix of very short (3 mile) and longer motorway (150 miles) journey's. Whenever I reset it it's always back to 27.7 (or 27.9 if I'm lucky) within a few days.
Would be interested to hear if anyone experiences a significantly better MPG when using Super Unleaded?
