PEUGEOT unveiled estate versions of the 307 and 206 as concept cars at the Frankfurt International Motor Show this week, hinting at future variants of the two cars.

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.
