IMPROVED economy and refinement are hallmarks of SEAT's upgraded Exeo executive saloon and ST estate line-up.

With prices from £19,480, the stablemates both come with a revised face featuring bi-xenon headlights with LED daytime running lights, new alloy wheel designs and revised upholstery.

Improvements to the 2.0 TDI diesel engine see emissions cut to as little as 129g/km while economy now sees the Exeo saloon capable of 58.9mpg on the combined cycle.

The Spanish company says that later this year there will be an Exeo Ecomotive version with Start/Stop technology and the target of sub-120g/km emissions.

And 2012 will also see a new Ibiza supermini raage and the Mii city car make their UK debuts.

SEAT chief Peter Wyhinny said: "The showroom arrival of the freshly upgraded Exeo range comes at a great time for SEAT. With another record year under our belt in 2011, and sales continuing their upward trend so far this year, our dealers are already busy."
