What would be the best and cheapest way to improve (even further) the fuel efficiency of a ncvt micra SLX?
I currently get 550-600kms from a tank.

» CMF MemberHi David, how much do you want!!. 600k's from the NCVT is pretty good.
I can get around 640k in my manual. You could try running slightly higher tyre pressures but sounds to me as if your at the optimum efficiency already.

» CMF Member1) Take weight out of the car. Front seats are very heavy. A/C & power steer. Spare tyre, jack, parcel tray, etc. There's been other disscussions about this
2) Run biscuit tyres with overinflated pressure. Lower rolling resistance. Should be lighter too.
3) Remove power steering.
Aside from the weight, from memory it adds about 2% to fuel consumption.
4) A manual gearbox should give you better economy than the CVT & it's lighter. While current model CVT's might come close to equalling the economy of a manual box, or in some cases bettering it, this is partly achieved because of an electronic throttle, which the K11 doesn't have. Newer CVT's also have a wider gear range.
5) Better inlet filter & cleaner flowing exhaust system.
6) Better computer & O2 sensor, running the motor leaner.

» CMF MemberAbout how much improvement in fuel consumption could I expect over the standard equipment if I upgraded the inlet filter and the exhaust system?

» CMF MemberWhen you say biscuit tyres...what are they? are you refering to the 155 ones?

» CMF MemberDude honestly the efficiency that you are getting now is pretty bloody good. You would have to buy a moto if you wanna get better than that.

» CMF Memberthe only problem with putting new improved breathing on the car is you might get better economy BUT you now have the huge temptation everytime you drive it to find out how much extra power you have..............

» CMF MemberAnother thing that has a major effect on fuel consumption is the suspension alignment.
e.g.
We experimented with a little front toe-in—just an eighth of an inch—and found that it had a profound effect on fuel economy, which deflated from 68.6 mpg to 63.2 at a steady-state 60 mph

If you run with zero toe at the front (like the Honda Insight), it will maximise economy to the detriment of straight line stability, turn-in etc.
