what makes you think they are not?
Ah, you talked to your dealer or you talked to Volvo in Sweden? I doubt anyone here has additional or better information.I asked their marketing people why it wasn't available as ordering option. They replied that there were no plans to make it available in the UK.
C'mon mate! You live in a teensy tiny country. Can't you drive across and back on one charge! We need to 2000 km extended range battery in Australia to make it to the next charger.Why will Volvo not bring the extended range version of the MY24 XC40 to the UK?
