Guys,

Chk this out,

The 3-stage VTEC D15B represents the pinnacle of development on the D15B engine. From the same configuration as the previous generation VTEC D15B; 1493cc SOHC PGM-Fi but now with the 3-stage VTEC system; it generates the same 130ps at a higher 7000rpm with a max torque of 14.2kgm at 5300rpm. The amazing thing is that now it also offers an incredible 30km/l mileage ! In the flesh, the 3-stage VTEC D15B is a sleeper. The valve cover does not have any 'VTEC' wording and only the sharp eyed will recognize the engine as VTEC by noting the VTEC switches (yes, two of them) located on top of the intake runners and the high 7200rpm red-line of the tach. The 3-stage VTEC engine runs in 12-valve mode up to around 3000rpm. In this range, running in ideal conditions will activate the 'lean-burn' mode, where air-fuel ratios as high as 20:1 can be used to take advantage of the intake swirl induced by the 12-valve operation. This lean-burn mode is what makes the 30km/l mileage (for constant 60kmh speed) possible. A green 'ECONO' LED lights up on the dash when lean-burn mode is engaged.

this could be under test conditions where real world figurs are way too different than they claim to be. If a honda does 85 mpg like this claim to be, there's no need to invent prius or any hybrid with all effort.

^^ heh heh agreed. Maybe if u have a flat surface and no need to brake for like 30kms and if u could just run within 3k rpm on 3rd or 4th gear without changing between gears, i think you could achieve those figures, and also given that your car is in factory condition :D

You guys are someday, really gonna have to learn to read.

This lean-burn mode is what makes the 30km/l mileage (for constant 60kmh speed) possible

Basically, if you do 60 on the top gear you'll get it in a properly maintained car. which means no braking, no acceleration, just 0-60-0 in order to get that.

14 for auto and 16 for manual is realistic. In fact i manage to squeeze out 14-15 on my 406 in out of colombo trips and a well known carina auto gets about 16 on such trips, so no biggy in honda getting the same mileage.

so It seems there is nothing wrong with my EK.

Let us wait for the next price cut down for fuel. (Another election is sheduled =there is a chance.)

Cheers
