Mercedes-Benz has expanded the new S-Class line-up with a new plug-in hybrid S 580 e, offering a 63-mile zero-emission range.

The new model is priced from £104,490 and comes exclusively in long-wheelbase configuration.

It uses a 3.0-litre six-cylinder petrol engine, combined with an electric motor and 28.6kWh battery, to deliver 509PS.

The CO2 emissions figure for the car is 18g/km, while its claimed fuel consumption is 353mpg.

An electric-only range of 63 miles places the car in the 7% benefit-in-kind (BiK) tax band.

The battery can be recharged from 10%-80% in 20 minutes using a DC rapid charger and in less than four hours using a 7.4kW wallbox.

Four specification levels are offered, starting with AMG Line Premium. Standard equipment includes 20-inch alloy wheels, a panoramic sunroof, remote parking, 360-degree camera system, active cruise control and heated and cooled front and rear seats.

The AMG Line Premium Plus is priced from £109,385 and adds an augmented reality head-up display, heated centre armrest and door panels and 21-inch wheels.

Either model can be specified with the Executive Line package. This consists of a rear-mounted tablet, electric sunblinds for the rear windows and the Chauffer Package with a foldable, removable head restraint on the front passenger seat; front passenger seat adjustable from the rear; and electrically extendable footrest behind the front passenger seat.

The Mercedes S 580 e is available to order now and will arrive in the UK towards the end of the year.
