Well enough. It's almost like driving a manual, but it's actually an auto, which I didn't mind at all. I quite like feeling the engine behind the accelerator, it makes things fun and at least feels like I'm driving the car, rather than it being on autopilot.
It's not exactly smooth, and the stop-start feature turns on as soon as the car pauses which is something to get used to. The 1.2-litre turbo-petrol engine doesn't necessarily have a lot of power, but it has a lot of zip and I feel like I'm in a little European car, zig-zagging through traffic, because it's quite agile.
The steering is responsive, I can hit the accelerator and overtake easily, it zooms up hills and is a fun experience. Driving in the Citroen C4 Cactus evokes memories of zooming across the autostrade in country France, and winding through tiny streets in small European villages.
