The main feature of the 307 SW is a full-length glass roof from the windscreen to the rear of the passenger compartment, and adjustable and removable rear seating.
It is developed from Peugeot's Prométhée concept, and has a wheelbase four inches longer than the standard 307 hatchback, while the body is more than four inches longer and an inch taller.
It seems likely that Peugeot is also planning a compact MPV version of the 307 which would compete against the Renault Scenic and Citroen Xsara Picasso.
The 206 SW shows a possible new body profile for the car, but the concept has been given sporty styling with a body kit, 17-inch wheels and a double exhaust pipe. It is fitted with a 180bhp 2.0-litre engine and has sports seats. It appears that Peugeot will be gauging reaction to a hot variant of the 206 and not a competitor to the Volkswagen Polo, Skoda Fabia, SEAT Cordoba Vario and Toyota Yaris Verso estate models.
A Peugeot spokesman said despite being based on current models, the cars were concepts and not production-ready vehicles.
