Performance & drive
What it’s like to drive, and how quiet it is
Engine, 0-60mph and gearbox
The Citroën Grand C4 SpaceTourer's 129bhp 1.5-litre diesel engine (badged BlueHDi 130) is easily up to the job of hauling around seven people and a boot full of luggage.
The only other option is a 128bhp 1.2-litre turbocharged petrol engine (badged PureTech 130). You might think that a small petrol engine like that would struggle in a big MPV but it's a surprisingly flexible performer that's actually quicker than the diesel.
The rival Ford S-Max and Touran are more enjoyable to steer along winding B-roads.
Noise and vibration
The BlueHDi 130 diesel engine is fairly smooth and quiet for a diesel, but the PureTech 130 petrol is quieter.
The manual gearbox has a notchy, imprecise shift, while the eight-speed automatic gearbox swaps cogs smoothly but is quite slow to respond when you ask for a sudden getaway. In fact, it can feel downright ponderous in some situations.
Overall refinement is otherwise good, though. Wind and road noise are well suppressed, making the Grand C4 SpaceTourer a relatively relaxing motorway cruiser in the MPV class.
