As with the larger Astra range, the two models have different styling – the three-door a more sporty stance with the five-door being more practical.
The five-door model debuts a new DualFloor system which allows the luggage floor to be set on two different heights thanks to a removable panel.
This panel can also be used to divide the load bay into two smaller areas to reduce loads from rolling around in the boot.
Another new feature is FlexFix – essentially a drawer which can be pulled from the rear bumper with the capacity to accommodate up to two bicycles.
Engine options mirror the three-door, with three petrol and three diesel engines.
Prices will be announced for both models at their debut at the British International Motor Show on July 1.
