Hi all.

I picked up my brand new Vito 111 manual yesterday and took it for a nice long drive along the freeway.

All seemed well, but I was astonished to see that, at a cruising speed of 100 kmh (62mph), in sixth gear, the revs were up around 2200 RPM and about 2400RPM at 110kmh. This means that at highway speeds, the noise/vibration levels are almost unbearable.

I think that the torque of the diesel would have warranted a much taller sixth gear.

My last car (2004 Ford Falcon E-GAS ute auto) does about 1700 RPM at 100kmh, cruises beautifully on the highway, so taking the Vito on the highway was like stepping back in time. I do a lot of highway miles, an I am quite worried about this.

Is this normal?

If so can the diff ratio be changed?

The speed / revs you quote is exactly the same as my 115 however I don't have any vibration and I would say very acceptable noise levels especially considering mine has clocked over 250k.

Only option is the 2.92 from the 120 or 122cdi, over the next month I’m doing that to my 115cdi. Once it’s intalled you have to use star to code it to the Speedo and ecu. This will bring rpms down from in my Vito 2260 @ 62mph down to 2020 @ 62mph.
Eventually I want to get a ring & pinion from a E280cdi or C320cdi which run 2.47, that will bring the 62mph speed back down to 1700rpm. Only question is wether is that ring and pinion with fit in the Vito diff housing and if the star software is able to code that ratio into the ecu and Speedo

I'll be interested to see how you go with changing the diff.
I have a 122 that is doing 2000rpm at GPS 102kmph which is reving much higher than need be. With the torque of the V6, I'd agree that 1700rpm should be the revs for that speed.
My van has the 225/55 17 tires, I wonder if any one has used 235/55 17 tires with 7.5 inch rims.

Hi Conrad, yes 1700rpm would be perfect, going taller tyres I worked out once is 1.5kph you gain at every 1000rpm for ever inch higher in diameter you go. So 1inch higher would take you to 105kph at 2000rpm. Not much of a gain for the loss of acceleration you would have to sacrifice
