BMW E9X 335d as a fun daily commuter car in 2024

[Jcp045]

Hi I'm changing jobs and my new commute will be 100 miles round trip. The journey is mostly motorway m25 (essex to Kent) over dartford bridge. Is a BMW e91 touring 335d the sweet spot of fun and decent mpg or am I well off it.

If I could get 45 mpg out of it and Remap it to stage 2 that looks to me like a crazy fun power to mpg ratio for a daily.
I currently have a tts that gets me around 28mpg on the same journey.
Let me know what mpg you get out of yours. Or if there is a better car out there for this journey.

Any thing with that engine doesn't need a remap , its a never to be repeated engine

"stage 2" is more than just a remap - bigger intercoolers, air intake etc

Different drivers will get different mpg on the same journey.
If you're only getting 28 in a TT, you'll not be the most economical in a 335.

You can get great mpg from a BMW diesel, cruising steadily at a good pace on a relatively empty motorway.
Traffic knocks it though.
The CO2 rating tells a story!
A mate has a 535. It's good on long runs, probably 50mpg cruising up the M5 when it's quiet. But a rush hour trip into Exeter dents the average from a tank. the other costs over a year seem to make a few mpg a bit of a sideshow. Suspension bills, tyres, brakes, all the bits cost more than a Ford...A very nice car though.
Also E91 is old now, a lot have corrosion underneath at the back, as MOT advisories.

You won't get 45mpg out of a 335d.

I've averaged 36MPG over several tens of thousands of miles.

It's an old M57 engine, with an old 6HP gearbox. Both of which were designed before the millenium...
