The minor changes to the Seat Exeo are designed to appeal to business users as Seat looks to expand its commercial operations in the UK.
With this in mind, the front seats have been redesigned to have a thinner profile, while the rear shelf has been moved to increase the amount of space passengers have in the back of the car.
Outside, LED lights have been added to the rear and there is now an option to install bi-xenon headlamps to both body styles.
The biggest change comes in the 143PS 2.0-litre TDi variant. A new continuously variable multitronic gearbox has been added as an alternative to the six-speed manual transmission for the first time.
As a CVT transmission, the multitronic maximises the efficiency of engine at all times, and although it needs power to operate, it is more efficient than automatic gearboxes and nearly as efficient as the manual option.
Both the Seat Exeo saloon and Seat Exeo ST offer 48.7mpg on the combined cycle when fitted with the multitronic transmission, which will be showcased for the first time at the Paris Motor Show on 30 September.
The figure is expected to drop when Sport mode is selected, which offers gear shifts at higher revs, while a manual mode can be operated through wheel-mounted shift paddles.
It is not a vast overhaul of the Exeo for Seat, whose smaller cars such as the Ibiza and Leon are popular sellers in the UK, but Seat hopes the tweaks will increase fleet sales already bolstered by a high profile deal to supply British Gas with a fleet of Seat Leon Ecomotive models.
Prices and full specification for the revised will be revealed closer to the UK launch.
