Three new engines are set to bolster the UK S-Class line up to a total of 11 different models.

The S 300 BlueTEC Hybrid L AMG Line, S 600 L AMG Line and S 65 AMG L will be available from April 2014 production, extending the range to now include the first diesel hybrid engine in the segment with class-leading economy, through to the ultimate in refinement, power and performance in the form of the S 65 AMG.

The S 300 BlueTEC Hybrid L AMG Line is the second engine for the S-Class Hybrid offering (alongside the S 400 Hybrid L), and is from the same engine family as the successful E 300 BlueTEC Hybrid, with a 2.2 litre, four-cylinder diesel engine joined by a 27 hp electric motor. With a combined fuel consumption of 61.4 mpg and CO2 from 120g/km, the S 300 BlueTEC Hybrid sets a new efficiency benchmark in the segment and is available from £72,260 OTR.

In addition, standard equipment across the entire S-Class range, including the S 300 BlueTEC Hybrid, from March 2014 features an innovative touchpad system that allows control of COMAND Online using single or multiple-finger gestures, and new optional features include the new Head-up Display, which provides the driver with key information at a glance without having to take their eyes off the road, and heated windscreen.

For the two V12 models, the S 600 L AMG Line and the S 65 AMG L, they represent the ultimate levels of standard equipment. Key features include: Executive Rear Package and Rear Seat Reclining Package for backrest adjustment to 43.5 degrees; Rear Seat Comfort Package including Rear Seat Entertainment; Front Seat Comfort Package; Exclusive nappa Leather Package; Burmester 3D High End Surround Sound system; and Keyless-Go Package to include remote boot closing and hands-free access.

In addition, the full Driving Assistance Package to include driver aids like Active Blind Spot Assist and Distronic Plus with Steer Assist and So & Go Pilot, is standard. Magic Body Control, Night View Assist Plus, Warmth Comfort Package, Intelligent Rear Seat Belt Package, garage door opener, TV tuner and rear seat telephony are further examples to add to the superior levels of equipment for the S 600 L AMG Line and S 65 AMG L.

In fact, only a few selectable options remain for the 12-cylinder models besides the paint, upholstery and trim choices, including the Individual Rear Seats Package (£2,900) and a refrigerated compartment behind the rear armrest (£1,130).

The S 600 L AMG Line, priced from £139,960 OTR offers a 13 hp increase over the previous S 600 model to 530 hp, with 830 Nm of torque, accelerating from 0 to 62 mph in 4.6 seconds. Emissions are reduced by 21 per cent to 259 g/km with a 27 per cent improvement in combined fuel consumption to 25.5 mpg.

The impressive figures continue with the S 65 AMG L, which is priced from £179,960 OTR. The 630 hp and 1,000 Nm of torque help to propel the S 65 AMG L from 0 to 62 mph in 4.3 seconds – a 0.1 second improvement over the previous S 65 AMG L. In addition, there is a 16 per cent decrease in CO2 emissions to 279 g/km and a 20 per cent improvement in combined fuel consumption to 23.7 mpg.
