Paris motor show - Saab 9-X Air

This is the Saab 9-X Air concept, which previews not one but two potential future cars.

As well as hinting at how the 9-3 Cabriolet will look, it gives clues to Saab's mooted VW Golf rival that could go into production in 2010.

The concept car is a convertible version of the 9-X BioHybrid that was shown at the Geneva motor show earlier this year.

New convertible design – and a radical boot
The car shows off Saab's future convertible design direction, with a folding fabric roof mechanism that collapses and folds inwards.

Once down, a screen rises so the driver is surrounded by glass, offering ideal visibility but avoiding any wind buffeting.

Saab has called this system 'Canopy Top', which underlines how likely it is to make production. The design has already been patented by Saab.

The boot space is an even more radical design – but is less likely to make it to production. Instead of being accessed by a lid, it slides out from underneath the rear lights. It's spring-loaded and slides on rollers, and is large enough to carry two golf bags.

Behind the wheel
The Saab 9-X Air concept is powered by a turbocharged 196bhp 1.4-litre engine that uses biofuel and hybrid technology to reduce emissions. It accelerates from 0-62mph in 8.1secs and emits 107g/km of CO2.

The cabin features a wraparound dash that extends to the top of the driver's door moulding and includes five embedded display screens.

Bluetooth technology also allows the car to download information from occupants' mobile phones to update music files or sat-nav details, for example.
