From the last generation to this current one, you can really tell the Insignia has grown when sitting up front. There’s plenty of width so two adults can sit side by side without fear of brushing shoulders, and the seats go back far enough for the longest legged of drivers. Head room is unlikely to be a problem, either.
Storage is good, too. The front doors have generously sized pockets that can take a small bottle of water and plenty of other bits and pieces and there’s a spacious cubby under the centre armrest. In front of that is a pair of cupholders and another lidded cubby with enough space for a smartphone.

While there’s plenty of room up front, the back seats are a bit of a mixed bag. We doubt anyone will be complaining about the amount of leg room, because even our six-feet-tall testers found their knees nowhere near the back of the front seat with a similar sized adult up front. More of a problem is head room: the roof curves down at the back of the car, so taller people may find their head uncomfortably close to the roof.
There’s also a large hump in the middle of the floor that makes foot room tighter for someone sat in the centre seat. Meanwhile, the rear door pockets are much smaller than those up front and only Tech Line models and above get rear USB ports as standard, though.
Vauxhall Insignia Grand Sport seating flexibility
There’s nothing particularly clever about the Insignia’s seats. While the driver gets seat height adjustment the passenger doesn’t, unless you specify either of the top two trims that also bring passenger lumbar adjustment as well. The rears have a typical 60/40 split with the nice asset of electric release switches conveniently located in the boot to fold them down.

The Insignia’s boot is certainly big enough for a couple of sets of golf clubs or a big pushchair, but it lags behind the class best - the Ford Mondeo and VW Passat beat it comfortably, while the Skoda Superb is over 100-litres larger.
Unlike many of its competitors, you don’t get a variable-height boot floor, even as an option, but at least there’s not a vast step left in the extended load bay when the rear seats are folded down.
