I wonder which vehicles that is - is that predominantly the non-pluggable Prius?

There is a wide variety, MHEV is quite popular here due to lack of home charging, as many people live in terraces, etc

We have a selection of smaller popular hatchbacks with MHEV available (ie, the Hyundai i20) that I believe were not released in some markets

The leasing culture for "luxury" cars is quite prevalent here too, and many new cars from popular brands such as Land Rover are at minimum MHEV from new nowadays, in order to get fleet emissions down
