Think of the advantage- you don't have to downshift every time you slow down. Makes a strong case for itself with cars having turbo lag.

I think this has to do with the additional weight of your car. (I mean compared to a swift vxi ). Both cars ( vxi and zxi ) share the same engine. My car does 80 at 2200 RPM and 100 kph at exactly 2750 RPM.

Experienced friends may shed some more light here.

Thanks & Regards,

Sajeesh

If Vxi and Zxi have the same engine and the same gearbox, they will have same engine rpm at given kmph in 5th gear.

If prithm notices higher rpm, he shall check the rpm once again (if he is reading the meter correctly). If the reading is correct prithm needs to check his clutch.

Thank you guys for lightening my heart.

Yes Sajeesh/Rahul. I always checked this with full tank and at mild cruising only. I have a very delicate foot. But surprisingly I noticed one this weekend that it might have to do more with wider tires of ZXi than LXi or VXi models. Though tyre pressures are maintained at OEM standard.

a4anurag : You might relate to this more since both of us are from same location. I tested this in ORR and tested this speed ratio near Gandipet lake stretch which is the longest without bends in ORR. Though the terrain is as flat as it can get, but still I had to push it above 2800 RPM to get that 100 mark.

Regarding the NVH, I have done a double coat of sound deadening by TufKote and two coat of anti rust paint. So, compared to vanilla ZXi, mine is much quieter which is little irritating for me.

In S Cross DDiS200 on highway,

120 kmph @ 2000 rpm - 5th gear ( pic attached) - Note the mileage at this.

Some discrepancy here. Needle is quite far from 120 kmph and 120kmph @2000 rpm in 5th gear seems too good to be true. Bhpian Breezydrive (Your car's engine rpm at highway cruising speeds)reports this speed in 6th gear in his S cross 320.

Read as 100 km/h at 2000rpm ( as in pic)

@100Kmph - 1800 RPM
@120Kmph - 2000-2200 RPM


2015 Honda Civic 5SP AUTO (1.8 iVTEC)
@80Kmph - 1200 RPM
@100Kmph - 1500 RPM
@120Kmph - 2000 RPM
Seems unusually low engine speed for high revving petrol cars. But it is good if your cars delivered this performance.

My experience
Honda city GXI (2003) - Approx 3500 RPM@100 kmph
Honda city AT (2009) - 2800 RPM@100 kmph
Ford Fusion (2005) - 2900 RPM@110 kmph
Chevy Forester - 3000 RPM@120 kmph
