Our Yaris Hybrid long-termer has now been returned to Toyota, and having used it for several months there's just one thing which, for me, prevents this from being at the top of the supermini class – a spark.

In many ways it epitomises what a modern supermini should be.

It has smart looks, a roomy interior with a decent-sized and practically-shaped boot, is well-built and has excellent efficiency.

CO2 emissions of 85g/km and an official combined fuel economy of 76.3mpg keep costs down for both employer and employee.

However, it doesn't engage the driver in the way a rival like a Ford Fiesta might.

It's pleasant to drive but never exciting, with comfort and refinement valued far above an entertaining driving experience.

After initially being underwhelmed by this, it didn't become a problem.

In fact, it became one of the qualities I liked most about the Yaris.

It's a very calming and serene drive, and does much to take away the stresses of rush-hour motoring. You know there's no reward in pushing on, so why bother?

This approach also suits the characteristics of the petrol-electric powertrain and CVT gearbox perfectly, although it hasn't helped me achieve the official fuel economy figure.

I've averaged 58.3mpg, but most of my driving involves A-roads, so the hybrid has been out of its natural habitat.

However, any urban-based fleet should be closer to the official figure.
