The car has a glass roof with special heat resistant glass and a full-length shutter and almost MPV-like flexibility with the option of up to three rows of seats.
Its wheelbase is 10cm longer than the 307 hatchback, and its interior layout can be adapted to accommodate up to seven people thanks to the individual rear seats being removable.
It also features several MPV-like design features, such as fold-down tables from the seat backs, storage drawers, 12-volt power sockets and an air conditioned glovebox.
The Peugeot 307 SW will be offered with a choice of 1.6-litre or 2.0-litre 16-valve petrol engines. The 90bhp and 110bhp versions of Peugeot's 2.0-litre HDi turbodiesel engine are also available and a semi-automatic gearbox is available on 1.6-litre petrol models.
On sale in the UK in May, the 307 SW (pictured) will have six airbags as standard, active front seat backrests, emergency brake assist and three-point retractable seatbelts for each of the seven seats.
