The new generation of Mercedes-Benz’s seven-seat GL-Class will go on sale in Britain in January 2013, with the German automaker offering two models, the diesel-powered GL 350 BlueTEC AMG Sport and, for the first time, the high-performance GL 63 AMG.

Beginning with the base model, the GL 350 BlueTEC AMG Sport is priced from £59,465 OTR. It is powered by a 3.0-liter V6 turbodiesel engine rated at 255bhp (258PS) and 620 Nm (457 lb-ft) of torque, and accelerates to 62 mph (100km/h) in 7.9 seconds before topping out at 137 mph (220km/h).

Compared to its predecessor, it offers a 15 per cent increase in combined fuel efficiency to 35.3 mpg UK, and a 14 per cent reduction in CO2 emissions to 209 g/km.

It also gets more standard equipment over the previous model with features such as Intelligent Light System with bi-xenon headlamps and LED daytime running lights; an AMG body kit together with 21-inch AMG alloy wheels; privacy glass; an electric glass sunroof; AirMATIC air suspension; Parktronic with Active Park Assist; and COMAND Online with media interface and DAB digital radio tuner.

Naturally, there’s an array of optional features, including a Parking Package with a 360-degree camera (£675); panoramic sliding sunroof with interior sun blind (£920) and an On- & Off-Road Package, which offers six programs to adapt the vehicle configuration to the road surface (£1,985).

For the first time, Mercedes will offer the GL 63 AMG model in the UK with pricing set at £91,680 OTR. The high-performance SUV gets a 5.4-liter bi-turbocharged V8 good for 550bhp (557PS) and 760Nm (560 lb-ft).

In this configuration, the GL returns a 0-62 mph (100km/h) time of 4.9 seconds and reaches a limited top speed of 155 mph (250km/h). The AMG variant has a combined fuel consumption of 23.0 mpg UK with CO2 emissions of 288 g/km.

Additional features over the standard GL include a full body kit, bespoke 21-inch wheels, Active Curve System with AirMATIC, an AMG leather interior with sports seats, front and second row heated seats; Memory Package and multi-contour front seats with massage function, and “luxury” automatic climate control.
