Your write-up of the Renault Koleos (First Drives, November) criticises the continuously variable transmission for “forever hunting for the right ratio while the engine droned away”. This is exactly what CVTs are meant to do!

It is also a reality (sad and unfortunate in my book) that for many drivers a vehicle is simply an appliance rather than a passion. For others, features and comfort and economy are far more important than the feeling of driving a manual sports car.

When reviewing vehicles made for this reality, it seems unfair to criticise something for working exactly as it is designed to do.
