The Ford Ka's greatest weakness is the previous model.
Despite this latest version getting lots more fancy plastics inside, better
packaging for the rear seats and boot, and now a diesel engine, there's simply
no way it can ever exceed the heights the first Ka reached. Not with a chassis
as dull as it's got.

At least the diesel adds another level to this latest version.
It doesn't transform it into what we'd want from a 21st-century Ka,
but it does at least go for ever on not much fuel. The combined fuel figure is
67.3mpg and CO2 is 112g/km. Impressive stuff, to the point where you wonder
what the forthcoming Econetic version will manage. Just how low can these
things go? Perhaps it'll spray lavender in the air.

The trouble is that the execution isn't quite as good as the
theory. Around town, it's all pretty quiet and refined, but at motorway speeds
it buzzes quite a bit. I seem to remember the Fiat 500, which shares the same
engine, being quieter. The Ka doesn't feel underpowered though. Even at those
motorway speeds it's responsive and it doesn't feel overwhelmed out of town.

It's just a pity the whole package is underwhelming.
