Hardware update gained 15% range

Post by FENorway » Tue May 14, 2019 3:56 pm

Did a hardware update today which will increase the range by almost 15%.
The update was done by FTTM(ferry to the mainland) and MTOTA(money transfer over the air)
Paid 950 euros for the update. I've only downloaded it to my garage and will install it to the car later.

No.
Thought that using the 18" for longer journeys and increase the lifetime of the 22" was worth the money.
Its 1% of the cost of the car.

I’ll be getting 18s for winter months :) For summer 20s that came originally with the car seem not too bad!

Every time I see the I-Pace with 18's it amazes me how it somehow makes an 18" wheel look so tiny. My current car has 16" wheels and even those don't look as small as 18"s on the I-Pace. I think it's the huge tyre sidewalls tricking the eye perhaps?

Do we know how it reduces the range so much having a bigger wheel? Presumably the rolling radius of both wheels and their respective tyres is roughly the same? I'd have thought the reduced flex in the smaller tyre vs the bigger tyre would help get more power to the road, or is it simply a case of the smaller wheel package being lighter?

Significant less weight and lower rolling resistance. Aerodynamics plays a minor role I guess.

Around 20 miles on 20’s

Around 30 miles on 22’s (from 18’s)

I think the width of the tyre also is an impact.

I think the most important parameter is the fact that there is much more mass further away from the axle, so a lot more energy is required to accelerate to the same radial speed. The wheel is probably also heavier overall.

20" 5070 with GY Asymmetric 245/50 28,8 kilos
22" 5069 with Conti PC6 255/40 34,4 kilos

The tyres on 18 and 20 weighs the same. The difference is the rims.
