Engine, 0-60mph and gearbox
There’s a 1.6-litre diesel engine available with wither 128bhp or 178bhp. We have yet to drive either, but suspect both will offer more low-end pulling power than the petrol option, so they would be better bets for long-haul journeys with cars packed full of passengers and luggage.
That said, the sole petrol choice is impressive enough to recommend as the pick of the range. The peppy 128bhp 1.2-litre unit zips along nicely in town and manages motorway journeys easily, too. The diesels may have more pulling power, but in official 0-62mph sprints, the petrol will just about see off the lower-powered diesel, while the other diesel is only marginally quicker.
Suspension and ride comfort
The C4 Spacetourer’s supple suspension deals with big bumps pretty well, so you won’t have to wince every time you encounter a speed bump. Unfortunately, patchy, eroded surfaces unsettle the car a little too easily, especially at low speeds, meaning a trip through town isn’t as comfortable as it might be.
The C4 Spacetourer’s body also tends to bounce up and down a fair bit along undulating country roads; you’ll want to keep your speed down if any of your passengers are prone to travel sickness.
Wheel sizes range from 16in to 18in, with the former providing the smoothest and quietest ride.
The steering is light – that's great for manoeuvring at low speeds, but it’s also rather numb, meaning it doesn’t inspire confidence on faster roads.
While the C4 Spacetourer sways around quite a bit through tight twists and turns, it never lurches around uncontrollably, and there’s a reasonable amount of grip, so you always feel in control of the car. Just don’t hope for an enjoyable drive.
Noise and vibration
The petrol engine is nicely hushed at low revs but, predictably, pile on the power and engine noise gets quite grating as you chase the redline – and that’s something you’ll need to do if you want to get a proper shake on.
The manual gearbox has a notchy, imprecise shift, while the eight-speed automatic gearbox swaps cogs smoothly, but is still quite slow to respond when you ask for a sudden getaway. In fact, it can feel downright ponderous in some situations.
Refinement is otherwise good, though. Wind and road noise are well suppressed, making the C4 Spacetourer a relaxing motorway cruiser.
