Can you believe it's already been 40 years since the first G-Class rolled out? Starting out as a humble and rugged 4x4, the G-Class has evolved into one of the most sought-after luxury 4x4s in the market. Despite all that, it kept its signature boxy looks right into the 21st century.

In celebration of the nameplate's 40th anniversary, Mercedes-Benz recently released three special editions of the SUV called 'Stronger Than Time'. Equipped with unique exterior and interior add-ons, as well as a bevy of high-output engines, the Stronger Than Time G-Class editions serve as Mercedes-Benz's gifts to itself.

At the heart of the first special edition G-Class is a new 3.0-liter turbo-diesel inline-six. Dubbed the 'OM 656', it's available for the G 400 d and produces 330 PS along with a whopping 700 Nm of torque at 3400 – 4600 rpm. It also benefits from variable valve timing via Camtronic for better fuel efficiency and performance. Power is then sent to a nine-speed G-tronic automatic transmission.

Prefer gasoline power over-diesel? The second Stronger Than Time edition is powered by a bi-turbo V8 as the G 500. It generates 422 PS and a staggering 610 Nm of torque at 2000 – 4750 rpm. It too is connected to a nine-speed automatic gearbox.
