I generally don't use 6th gear unless I am going to spend a significant amount of time over 65-70mph. Using it at 40mph is going to really lug the engine.

Yes i agree rpm 2000, but in diesel engines they made rpm 1500 in 5th by 40 miles. It depends on the gear box ratio but asking here is perhaps dull because some ppl answer with some incapacity of reasoning further.

Dear N1,
you seem to be taking things very personally. Sorry to be "dull". It seems silly to me to put the car in 6th gear and drive at 1500 -2000 rpm (atleast in "petrol" engines). There's just no power in it. Could I? Yes. Would I? no. And that seems to answer, in my opinion, your question.

just watch your mpg gauge and it will tell you what gear you should be in for normal driving. If you are going 40 mph, but keeping the speed steady and not accelerating then keep it in 5th (the best gas milage), but going 40 and slowing and accelerating, then I would keep it in 4th. 6th is when I am going 70mph +.

If you're on a consistent road (no fluctuations in speed limit, sharp bends etc) and cruising (no steep inclines / declines) 6th gear is fine at 35-40mph but don't get lazy - be aware of what's occuring on the road and change up nice and early so you have grunt available when you need it

In the diesel, 6th is at 1500rpm around 55mph, which has enough torque to not feel like it's putting excess strain on things. As for this, 'don't use 6th unless you're on a highway or doing xmph?' Why should it be different from any other gear? If the car will put from 2000rpm in 1st, 2nd, 3rd, 4th or 5th then why not change up to 6th at the same revs? It's not an overdrive. IMO.
I often skip gears and tend to use 5th less than 6th (I did this more in my old car where 6th was good from 30mph up). 4th to 6th is a nice quick motion, then on slowing down, 6th to 4th or to 3rd with a blip. |

The N52 is happy to cruise along at 1000rpm. No harm to the engine at all. Just not too much toque at tap when you want it. So if you´re prepared to downshift once you need to accelerate, 6th is fine at 40. Actually best fuel efficiency for the speed.

wow, 40mph in 6th? never tried that before. i'm usually in 4th till i hit 55-60 so i don't hit 6th until like 70mph as well.
have to give it a try to see how mpg compares to lower gears at that speed...

Steptronic doesn't let you engage in 6th if you are going 55km/h or below. But to actually take advantage of the 6th gear economy, I find it to start at around 65-70km/h. Below that, 5th might even be more economical because of better torque when acceleration is needed. I use the 6th gear when I go at or above 65km/h for an extended period. In that case, I am not concerned without enough torque when I need it as all I need is a crusing speed of 65km/h.

vladinecko, bear in mind we're talking 320d's here (you know, one of those thing that doesn't need to visit a fuel station too frequently [just as well really, as I every time I do, courtsey of the UK fuel prices] ).
I've not got a lot of experience of my car yet (950 miles now!) but I would be hesitant to use 6th that slow, unless I was on level gradient or going downhill and not accelerating. OK, The torque of the diesel would cope with attempted acceleration better than the petrol engine, but my heart would sink as the economy gauge went right over and stayed there whilst my poor motor laboured me out of the situation. I'd be much much happier in 5th, and I don't think that the economy would be significanty worse (if at all), either. |
