The Mazda6 estate was shown for the first time at the Paris Motor Show, alongside the saloon.
The pair will make up the new Mazda6 range in the UK from 2013, equipped with Mazda's fuel-saving Skyactiv technology.
The third-generation Mazda6 will only be available as a saloon or estate, with no hatchback in the range.
Powertrains have been optimised to increase output and fuel economy. Chassis and body structures, meanwhile, are stiffer, benefiting from greater proportions of high and ultra-high tensile steels.
