Not Happy with MPG

I sympathise with new car buyers who buy their car where MPG is a big factor - only then to be let down by misleading figures.

That said, official MPG figures are possible if you drive really carefully. You have to remember that the Z4 is a sports car, and you're going to want to have fun in it, which inevitably means pressing the loud pedal quite hard on occasion (or more regularly 8) ).

I hope the MPG issue doesn't spoil the ownership experience.
 
I would say that on a reasonabally flat motorway / road if you set a 2.0 auto (any engine) to 50 mph in cruise control and then didn't hit any traffic you would get 40mpg plus for that part of the journey. But if you going to drive like that way did you buy a zed.
 
I know that I have already posted in this thread but I would like to retract my original statement due to a trip I undertook yesterday :)

Chauffeured a friend down to Donnington race circuit for a trackday (East Kilbride to Donnington and back 600miles) and decided to try and get a more accurate idea of mpg.

So brim to brim versus distance covered and came up with 41mpg :D

And here was me thinking BMW were telling porkies!

It would appear that on a proper journey the car is capable of surprising mpg figures.

All these poor figures makes you realise how efficient the S54 M engine is when driven normally! 27-28 is my average as a daily drive and that's a mix of town, A roads and motorways.

As said, maybe these turbo engines when pushed do hammer the fuel!
 
I found these figures from Autoexpress.

Difference between manufacturers' test results and average real-world driving in 2011 (drived from International Council on Clean Transportation, 2013)

BMW - 30%
Audi - 28%
GM - 27%
Mercedes - 26%
Fiat - 24%
Ford - 24%
Volkswagen - 23%
Renault - 16%
Peugeot/Citroen - 15%
Toyota - 15%
 
Just drove my new 35i with 4miles on the clock back from picking it up from the Garage from a cold start drove 20 miles average mpg says 34 well pleased with that and the cars sounds AWESOME :thumbsup:
 
Fuel grade does make a difference here too - 98/99 Ron fuel is even more important in a forced induction car as it allows additional advance on the engine, calculated by the knock sensors. My e85 3.0 is 2-3 mpg different between fuel grades, but remember it takes c.1000 miles for the ecu to adapt fully so one tank to try wont do.
 
I can get up to 32mpg from mine on the motorway. Average hooning around about 20mpg and the resetting before going on te track lowers it to 7mpg. However 7mpg is the lowest it will show and calculating the old fashioned way I was getting 4.3mpg at Snetterton.
 
I did Blackpool and back the other day at 38.2mpg averaging about 75 on the motorway and 60 on the a roads and dual carriageways.

Ahhhhhh - is this another "older engine gives better mpg" shocker thread?

A bit like the PSA engined Mini Cooper d - 65+mpg easy. Newer BMW engine, 55mpg. Same HP, both have DPF etc.

That'l be the Vreds working their magic :oops:
 
Had similar concerns re mpg when I bought mine back in January only getting very low 30's. Now with 3K on the clock averaging around 34mpg general mooching about regardless of driving style in sports or comfort mode. On a long run with cruise set at 80 can get up to 38 even higher when set at 70 but who wants to drive a Zed on an open road at 70?
 
I'm getting 31mpg over a tank in my 35i (thats calculated, not off the TC, which is reading 32.4). I drive like a granny to work and back though and that is mostly motorway.
Generally I've found that you will never get close to manufacturers quoted figures; I normally find that I get 15% off what they say.
 
I had this argument (poor mpg) may years ago with a Citroen dealer - The area guru came out and asked me to fill the car to the brim. We then did a 30 mile gentle drive and returned to the same pump and did a refill - The result was much better than manufacturers figures an me with egg on my face!
 
I have found that highway MPG approaches, if not meets rated numbers with the use of cruise control. So when on the highway, most of my driving is with cruise control engaged.
I also use the highest octane fuel available.

While I am happy with the MPG the car gets, I did not buy if for economy.
 
Depreciation hurts the pocket more than MPG.

Don't worry tho 'cos your coffin lid is nailed on for a long time! :)
