335i mpg at 70mph

[texasjohn]

That was a personal best, 40-42 normally.

I could keep it above 40 all week (there was 12 miles of non-motorway at the end of my commute through Bromsgrove then onto Kidderminster) and then it would dip to 30s while enjoying the weekends!

What mpg are people getting from the 130i as it's on my list as finding 335i/330i is somewhat difficult..

130i after a run keeping it 65-70 on the motorway:

70 my 123d got 45mpg recently - pah. Looking at 130i this weekend

My S40 T5 now that was bad - circa mid 20s

Bought my 1 year old 335i ,M sport last week, Did a 110 mile drive from Solihull to chester, set the cruise at 73 mph in comfort mode. Re-set all the computers before I left. So 99 % motorway driving. 42. 1 mpg lol, Not bad for 306 bhp 😄😄

Auto/DCT or Manual?

[trippy86]

These are some impressive figures!

A one post wander. I'd bet this guy had an F30. I managed similar in my F30 hybrid which was a 335i with KERS.

Getting 38-39 mpg at 70 (DCT, 7 speed helps)
34 mpg @ 90 mph

Z4 35iS (340 HP 1M variant of the N54)

But what is the point having a 335i and an empty motorway and only doing 70!?

Might as well have a 316d

Not really.

It's nice to have some poke on country lanes and when you want it. That and you'd probably be flooring the 316d to keep up with traffic and with not as nice an exhaust note .

Given all these stunningly good mpgs isn't it odd how the I5 Ford Focus ST owners seem to only able to get low 20's and apparently very pleased with it if they wanted an Eco box they would buy one.....

That's down to the owners IMHO, which aren't probably helped when they put an exhaust on ; it makes them sound a little more different .

We have 2 Mondoe 2.5Ts. Same engine as the Focus ST and heavier. I normally get 28MPG and on motorway trips around 32-35MPG at around 80MPH without trying. Pure town driving with stop start traffic will get them down to the low 20s.

In my E46 M3 I've once seen 34MPG doing a dead 70MPH from Birmingham to Warwick; the computer claimed 37MPG. Going to Germany following someone incapable of keeping to a speed (read cruising at 60 for a while and then cruising at over 90!), 134 miles of the Nurburgring and then driving back to the UK swiftly I averaged 29MPG.

Keeping below 80 in the X5 achieved 28mpg, which is very impressive. With cruise, 30mpg is possible, but thats the limits. A relative's 635d can achieve 47mpg on cruise at 70.

Anyone else done better?

Bloody hell. My E91 330d (manual) is showing 35.6mpg average over the last 1000 miles or so, with no urban driving whatsoever.

F30 335d LCI, 44mpg. How the flying F are you driving?

He has reset his trip computer once engine up to speed and then held a steady 70mph.

Do that in a 330d and you'll see mid 70mpg's.

I ignore the read out (in fact I have removed that read out) just go brim to brim over at least three tankfuls. As long as I get 500+ miles between fills I am happy.

It does get 500+ miles between tanks however that is a £100 tank. Our XC90 would get 550+ miles on a full tank which is £70-80

[sortedcossie]

I have a 2008 E91 330d Auto, standard car, I have to commute at least twice a month to Manchester from West Midlands, 97 miles door to door. I can get there and back 3 times on one tank as long as I keep it below 80mph.

I'd have to check when I next get in it, but I think it's average just over 39mpg over the last 2,500 miles. Not sure how accurate that is though.

[Mike335i]

Mine varies between 24mpg solely round town in winter and up to 37mpg on a very gently summer cruise. In truth I'm not overly fussed as I reckon I average over 25mpg per tank. My commute is 8 miles of mostly country roads then through town, so far from ideal.

[Fury RS]

My old manual E92 335i with a small remap circa 360bhp used to manage 37/38 mpg when the cruise control was set at 70 mph on a good run. I was and still am impressed with the consumption of that car considering it was a 3 litre twin turbo heavy petrol car...

[Dannbodge]

I've had 36 and 39.4mpg from my N54 335i on a long run

[DVandrews]

My old E39 M5 would do 24 on a run and 19-20 in general driving. My DCT 335i (N55) with 360 BHP remap averages 26mpg on general driving and has seen 32MPG on a long run on cruise control (70MPH).

[LordGrover]

I think mine has the same engine as OP's 335i.



Not done quite as well as OP yet as I rarely venture on the motorway. Averaged nigh on 30 mpg one month which included one of those rare occasions.
