It might be 33 years young, but there’s still a lot of life left in the Mercedes-Benz G-Class. The company has just announced plans to launch yet another update for the rugged off-roader at this month’s Beijing motor show.

The exterior changes for the G-Class consist of only minor styling tweaks (lights, mirrors) but the interior has come in for more serious attention. Specifically, the instrument cluster and centre console have been completely redesigned, while Mercedes-Benz’s COMAND online infotainment system, including a navigation system and internet access, is now standard.

In May 2011, Mercedes-Benz announced a special edition of the three-door G-Class which signalled the end of production of that bodystyle. The latest range therefore consists almost exclusively of five-door wagon variants, the sole exception being the G 500 (G 550 in the US and Canada), which is available as both a wagon or a short wheelbase two-door convertible.

The model range now starts with the 211hp (155kW) G 350 BlueTEC, which is powered by a 2,987cc V6 turbodiesel. Above this sits the G 500/G 550, which has a 388hp (285kW) 5,461cc V8 under the bonnet, as does the new G 63 AMG variant. In the G 63, however, there are two turbochargers so power rises to 544hp (400kW). The range topper is the G 65 AMG, featuring a 612hp (450kW) 5,980cc biturbo V12. The addition of the G 63 and G65 also means the end of production for the former G 55 AMG.

As for prices, in Germany, the range starts at EUR 85,311 (inclusive of 19% tax), rising to a breathtaking EUR 264,180 for the G 65.

Magna Steyr is contracted to build the G-Class at its Graz plant in Austria until 2015. No direct successor is expected.
