How about a motor on each axle giving a sort of four wheel drive and four wheel regeneration. See the attached pic from my RAV4 showing regeneration coming from both axles. It is great to get the traction on both axles when it is needed, as I did today, making a rapid right turn uphill at a T junction.
As someone else said, if no spare, then a much more common wheel/tyre combination, opening up more options for all season or winter tyres.
I love my gadgets. My Jazz is so old it has barely any, but my RAV4 has pretty much all the ones on the new Jazz. However, they seem to be better implemented. The option to not just have ordinary cruise control when you don't want ACC seems odd to me, especially since the ACC algorithm seems to be flawed. So buttons to turn things off please. My lane keeping is on a button, my lights stalk has an off and a manual setting.
If there is to be a Jazz V Crosstar, making it something a little more than a trim level and a one inch lift. A proper differentiation would be great.
Oh and, please, some jolly colours.
