The concept, called the GTC Paris, will be a pre-production model on which the new Astra will be based when it arrives in 2012.
However, Vauxhall has not revealed many details about the new design, instead explaining it will be based on the line ‘And the speed was pure beauty’, which has been taken from the novel, Jonathan Livingston Seagull.
In a short statement about the new concept, Vauxhall says the GTC Paris will mirror the character of the city it is named after and will feature ‘dramatic proportions and sculptural shapes’.
It has been confirmed the new Astra GTC Paris concept will be a sporty, compact hatchback and will appear alongside the latest addition to the Astra family, the Astra Sports Tourer.
The estate version of the popular family car will make its world debut at the Paris Motor Show from 2 October.
The Astra Sports Tourer will be sold in the UK next year and it will be built solely at the Ellesmere Port facility in Cheshire alongside the five-door version.
Featuring up to 30 litres more boot space than the Astra hatchback, the Astra Sports Tourer will be capable of carrying up to 1550 litres when the back seats are folded.
Vauxhall will showcase the two all-new vehicles alongside the Vauxhall Ampera extended range electric vehicle – due to go on sale in 2012 – and the new Meriva, which has been updated to include more a more efficient diesel powertrain.
Finally, the Vauxhall Corsa ecoFLEX supermini will appear at the Vauxhall stand in Paris. The low-CO2 model has been fitted with Start/Stop technology for the first time, meaning fuel consumption is increased by seven per cent to 70.6mpg.
The Paris Motor Show runs from 2-17 October and includes new and updated vehicles from most major manufacturers, including Ford, Renault, Peugeot, Citroen and Land Rover.
