Best RPM to shift for maximum MPG?

richie_s · 05-11-2015, 08:46 AM

I turned on the shift point indicator for the first time today and I noticed that it asks me to shift a lot later than I normally would. I usuall shift at around 2,000 rpm but the shift indicator sometimes doesn't even ask until I'm past 3,000 on small hills. On flat land, however, it does ask me to shift pretty early.

Should I be shifting later on hills for better mpg? It feels weird hitting 3,000 rpm in normal driving no matter what condition I'm in.

Best mpg = trade car in for a Prius

I was just going to say, if you're driving your 335i in ECO mode the whole time, just drive all the way to the Grand Canyon going 55MPH and don't stop.
Sorry, it just defeats the purpose of a fun motor.
Luckily with direct injection in our motors you can drive like a grandma on the highway and get some pretty efficient gas mileage. Your car will do all the calculations based on your trip, it tells you all the avg fuel consumption, etc.

There is no magical shift point necessarily as it depends on the road ahead.

But, most gas is wasted between shift points and unnecessary acceleration.

The key is just using least amount of pedal to maintain speed and avoid boost.

Idle rpm

Diesel > Gas
MPG/Torque Monster and in my area Diesel is less than Premium Gas (93)

MPG efficiency is more a function of load rather than RPM. Lugging the motor at low RPM with high load is about the worst thing you can do for gas mileage.

That's what I figured from this. I just have the habit of never letting the revs go above 3,000 during normal driving. I'm not too concerned with hypermiling my inline six though

just curious, that's all!

Turned it on? How do you turn it off? LOL!

go into eco pro mode and shift when it tells you. When you have 5 stars on all categories go to your local Toyota and buy a prius cause that is what your 5 starts unlocked for you.

I have MT. How do you get rid of shift nanny? Or is it always there?

I believe it is in the settings for the control display. you can toggle it on and off.

By the way, I think I've officially given up on the quest for better mpg.

Spending $50 more a month on gas > being frugal and driving like a granny

I'm happy to spend $100 a month in wasted MPG. I can't think of a better way to spend that money having fun.

Shift Indicator, who uses that

. Keeping RPMs low on hills and shift into a higher gear on a hill wastes gas, you are dumping fuel into the engine but the high gear is preventing the power from going to the wheels. BTW the shift indicator is always right. If you have a 335i you should not be worried about MPG as compared to the average 6 cylinder our engines are well below average.

How many times do you guys go past 3k RPM on a normal day ? Do you guys always drive on Comfort mode ? Or is it feasible, acceptable to daily drive on the Sport or Sport+ mode ?

I always feel bad when I floor it + I'm leased...

tjlees · 06-13-2015, 04:29 AM

At or under 1500 rpm on the highway - cruise and eco pro on. Music at 11. Gives 55+mpg (UK gals) for a straight six diesel. At 70+ I was struggling to get 50+ mpg out of a Prius though others claimed nearer 65mpg.

For twisties sport + on, auto to manual, music off, change up at just before 5.4k. ASD kicks in

Mpg drops to just over 30mpg ... But
