Mercedes-Benz S 500 L Plug-In Hybrid LondonMercedes-Benz will later this month begin deliveries of the S 500 L Plug-In Hybrid – offering 100.9mpg, 65g/km CO2 and 0-62mph in 5.2 seconds, all for £87,965.

The new plug-in hybrid S-Class boasts road tax and London Congestion Charge exemption, a 5% Benefit In Kind company car tax rate and 20 miles’ zero emissions pure electric driving on a full battery charge.

It also pairs a 333hp 3.0-litre V6 biturbo engine with a 116hp electric battery, for total system output of 442hp and 479lb ft of torque; that’s V8 power blended with four-cylinder economy, says Mercedes-Benz.

The new S 500 L Plug-In Hybrid is based on AMG Line spec, so is not even an eco-styled special. It has 19-inch AMG alloys, AMG body styling and the firm’s LED intelligent headlights as standard. Noise insulating glass is standard too, presumably to ensure the electric-drive peace is not spoiled by noise from outside.

COMAND sat nav is included as well, and this does include a special economy feature: it can predict where energy can be recuperated and prime the car to maximise this on downhill sections, topping up the batteries on the go. It will also predict when the car is about to enter urban areas and try to fully charge the batteries before it gets to them in order to maximise the electric-only range.

Public charging points can be utilised to recharge the 8.7kWh lithium ion batteries, with a full charge here taking around two hours (bank on it taking up to three hours if you plug it in at home). Mercedes-Benz also offers S 300 BlueTEC Hybrid and S 400 Hybrid models, but neither has plug-in charge capabilities.

The new Mercedes-Benz S 500 L Plug-In Hybrid goes into production later this month; UK deliveries will begin in November.
