LCI 550i Fuel Economy

Catfish454 · 08-14-2013, 06:06 AM

Is anyone driving a 2014 550i yet? If so, what kind of mileage are you getting? All I've heard is that it gets better mileage than the 2013, despite the extra 45 HP. Mine left Bremerhaven yesterday and I should have it by the EOM, but curious what kind of MPG I can expect.

It's the same as previous years

What did they do different for 2014 for the 550i engine. Is it a totally new engine or is it just a software/turbo tweak to get the extra hp and torque?

How is everyone getting such high MPGs... I'm getting 12-13 mixed...

There's a few stop and go. Even when I drive like an old person. I still get the same thing... i'll calculate it the manual way next time.

Reset it first. Then drive for a week and see if the numbers are better

I thought the higher output engine was introduced for 2013 (pre lci) but i guess i was wrong. it was only for 550 gt

this is the same engine in 6 series and 7 series. they finally put it into the 5 series

2014 has the newer N63Tu engine that has BMW valvetronic (variable valve timing) and likely is running a little more boost to make more power. Plenty of n63tu's on the market in 6er cars but don't know if anyone has measure boost / fuel changed over the previous n63.

I was wondering the same thing myself ... have a 14 550xi about ready to go into production next week ... and I am coming from an 11 535xi which I drive in sport mode 100% of the time and have a heavy foot ... I get about 16mpg now .... just worried how bad its going to be when i move up to the n63tu.

I went from a 2011 535i and averaged 20.0 mpg overall. I'm now in a 2013 650i GC and am averaging 17.5 mpg overall so far. So a 12.5% hit. Applying the 12.5% to 16 mpg gets you down to 14mpg. So 13-14 mpg would be an approximation for a 550i in your case.

That wouldn't bee too bad if your calculation is right in my case.

On a side note ... How are you loving the gc? I've had my eye on that since it came out ... But I had a hard time trying to justify the $110 k price tag to the wife

My avalanche with the 6.0L and 4:10's gets better mpg than the 550 does.

It's simply the price you pay to play.

Russkey · 08-18-2013, 11:43 AM

I get 15 mpg combined.
