Hi David,

First up, the Mokka has comfortable suspension, so it will be good from that point of view. The three-cylinder petrol engine has plenty of go in 136hp guise, and it's mated to a six-speed gearbox so it shouldn't be too audible, even at higher motorway speeds. It can be a little loud getting up to speed, but fine when cruising.

One thing to watch out for is that the GS version you mention rides on bigger wheels than the lesser models in the lineup. That means lower-profile tyres, which are likely wider as well. This can certainly add to road noise at speed.

And, while the Mokka is above average in terms of refinement on the motorway for its class, it is still a relatively cheap-and-cheerful small car, and you can't expect it to be as civil as larger and more expensive ones at higher speeds.

The best advice we can give you is to take one for an extended test drive, including motorway speeds on a variety of road surfaces - and make sure the stereo is off and anyone with you is quiet so you can assess if it meets your needs.
