45 mpg bmw

[bandit86]

I didnt think it was right except for the fact that it's my brokers car, 08 323 with a 2.5 L engine, 6 speed Had it for a year and it seems to be getting amazing mileage. Even correcting for the odometer error (5%) the highway mileage comes in around 45. Why is BMW not advertising this? Or is the car broken? There is a emission related fault keeping the check engine light on

It's a monster of a car if heavy on the skinny pedal, screams for more and faster like a nympho in heat. Just as much fun to drive too. My 94 325 got close to 30 mpg but I never cared about Eco driving back then and hardly ever drove under 75 mph

Maybe they put the "Super Secret" carburetor on yours......you have to keep the car under lock & key now or else they'll come steal it back in the middle of the night....shhhh.

My friend had a 335i that BMW claims gets 28-29 mpg highway. I never saw him get better than 20 mpg in mixed driving. You must have stole his mpgs.

my 95 525i regularly got 28-30mpg highway w a light foot. its quite possible since the 3 series is a bit lighter than a 5er.

Is this the same car that beat a Prius for MPG on the show "Top Gear"?

The test pushed the prius to it's top end while the BMW followed in loafing mode.

Did some cows just pass by here, I'm smelling something...

You need to check with 320Touring as he has a couple of BMWs and I think he would be dancing in the street with 45 (or the equivalent in Imperial MPG) even with his 318iS.

No, they ran it against an M3 coupe, the 335 is a mass produced equivalent made possible by BMW fitting the engine from a 5 series into a 3. The test was unrealistic of course (its TG after all ), a better comparison would have been both driving at the Prius speed.

(Disclaimer, I am both a Prius owner, a TG fan, and a fan of the real performance 3-Series the 335d which had to be detuned because it would outrun the new M3...)

I am also skeptical of the posters claim.........maybr it was in the liter mode......

What does this translate in U.S. Mpg? Keep in mind that the Prius is rated at around 76mpg Imperial.

[Arragonis]

Not sure, the 45 is not specified to be imperial or colonial gallons (sounds like Star Wars again...) - The location suggests Canada (Ontario) and I think we had a debate about the fact Canada uses Napoleonic measurements (l/100km) and Imperial gallons for MPG ?

Unless it was an EM'er with a fuel log Skeptical Hippo even doubts 45 (imp) for a 2.5L 6 cyl petrol BMW.

ok,

so its a 323 from 2008, that makes it an e90 or 91 (estate)

2008 BMW 323i (CA) E90 Sedan/Saloon automobile specifications and car tech data co2 economy fuel consumption

above is a link to the specs.

Personally, I think that even with the BMW efficient dynamics (stop/go) if it was available on this model, the car would struggle to achieve your claimed mpg.

Currently my best on a 4cyl 1.8 bmw using hypermiling techniques is 47 UK mpg, and that was on an extended Motorway run.


that is 39.21 US MPG.

My car is lighter than yours, with a smaller engine...so I dont see how your car can return these figures
