Food for thought - MPG

I routinely make a 160 mile trek to Baltimore, (Maryland), downhill and all on highways with 70 MPH limits. My benchmark is a 2 hour flat time, which is tough to do since you have to show 85-90 most of the way to do it. I get 26 MPG (US) at these speeds, but loafing along I can get 32 MPG. This costs me about 1.1 extra gallons, or 2.2 round trip. 2.2 gallons times $2.69 a gallon is $5.92. So, it costs me an extra $6 to drive 320 miles in a 'spirited' fashion as opposed to mini-van speeds. Hell of a bargin at twice that price in my book. Unless you guys are paying a lot more for gas, I don't see the point.

We are paying a lot more for gas

I think my 28i is currently averaging sub 25mpg

Z4rick, totally agree with you "drive it like you stole it" school of thought - and 95% I do hence why I only achieve 32 MPG and my car has been modded to improve its handling and power.

I posted this, as bit of a joke

- as there been a number of MPG conversations from 35i/35is owners.

Circumstances on Friday meant I could not drive quick on my 200+ mile drive due to traffic - and my 30 mile sprited drive over the A68 caused a issue between the wife and me lol - I dont know what I enjoyed more - the drive or wife reactions

However I am starting to consider an 35is as the next motor, as I dont do the millage as I used to do and cost of ownership is less of an issue.

However I would still like to know how a lighter more nibble motor will do compared a higher powered monster around a race track - as UK roads are not really suitable - and a 1/4 mile is not really a true test.

Saturday with the roof down and the sun shining was just bliss. Exhaust popping on over run and crackling on up shifts was brilliant!

Get a few mods and join the 300BHP club as it totally transforms the car

I think it will be mapped and lowered soon. I won't do anything else to improve power so somewhere around the 290-300bhp mark would be good.

Saturday was spent looking at houses so I doubt I'll be allowed to spend much on the car over the next few months

You might need a decat to get near those figures, I think 270/280 is more typical with just a map

You're probably right, I'm not too bothered about the peak figure, it's plenty quick enough at the moment but more is always better!!

I've not had mine long, but currently enjoying 23-24mpg which isn't too bad. About the same as my old 350Z and E46 330Ci previously.

I can manage 17-18mpg and up to 30ish on a motorway run. Don't think that's too bad, deffinitely better than the RX8 I owned a few years ago!

Edit: Should note work is only 4 miles away, reckon I could get into 20s easily if I didn't mostly drive round the doors

When I was in my 20’s and dating a model, I didn’t spend all my time f**king her – some evenings we’d kick back and watch TV

I can see where you're coming from with that, I find the repeats really get on my wick though

Mixed driving for me, averaging 27 - 28 mpg generally - Motorways can be as high as 34-35 mpg.

Happily second those figures. In Scotland however 60mph is very risky with all the speed (Sorry Safety) cameras
