Vauxhall holds the key to the prices Suzuki GB will charge for the revitalised Wagon R+ model it will launch at easter. Showroom prices will be revealed to the company's dealer network early next month - but they will effectively be set by the charges Vauxhall announces for its version of the jointly-developed 'crossover' city car.

'We have to be led by Vauxhall in this case. Our car will be competitively pitched against the Agila,' said sales and marketing director David Seaward when the new Wagon R+ was unveiled at the Geneva Motor Show. Despite being co-developed, the Hungarian-built Suzuki features different powertrains and will be unique in offering automatic transmission.

The auto option is likely to carry a premium of about £750 on the distinctively-styled Wagon R+, which is based on the mini series that has been Japan's best-selling car for the last three years. The Suzuki model will be launched with a choice of 1.0-litre and 1.3-litre petrol engines and two or four-wheel drive can also be specified.
