This topic is getting long and varied, although possibly a favourite for many.
Just wanted to comment here on
Wheel size. 17” v. 16” and which has the greater efficiency. It's not about the diameter of the rims, it’s much more about the tyres. See table for comparison.
As the
advance has a more powerful motor than the Basic, which is only available with 16” wheels, Honda specify the 17” gas burner wheels with lower profile, fatter/wider tyres as Standard. So you get “more rubber on the road”.
16” wheels are an option on the
advance, despite this table copied from Honda website! As the 16” rims are fitted with 55 & 60mm profile tyres, the actual diameter of the tyres are comparable. However the tyre width is 20mm less with the 16” rims. The difference in rolling resistance is due to the footprint of the tyres, which is where greater losses occur with the Michelin Pilot Sport 4 tyres.
For comparison consider the BMW i3 which has larger wheels, and narrow tyres. 155/70/R19
In general Smaller diameters are less efficient. And good quality of wheel bearings are essential.
