Mazda has refreshed its Saloon and Estate Mazda6 models. Highlights include technology updates, interior improvements and the introduction of G-Vectoring Control - which varies engine torque to each individual wheel, improving handling. As before, there are two petrol and two diesel engines on offer, although the 2.2 diesel unit now has reduced turbo lag and more torque. Prices are set to remain unchanged when the revamped Mazda6 goes on sale later this year.
