Mercedes needed a new Unimog, the company's massive off-roader that is sold mostly to construction companies, government agencies, and militaries, because the old one wasn't far from being illegal for sale. When the Euro VI emissions standard goes into effect, the old engines just wouldn't be cutting it anymore.
The new Unimog will be powered by a variety of diesel engines that produce between 156 and 354 horsepower and 479 to 885 ft-lbs of torque. That power will go to between two and six wheels, depending on customer specification.
Luckily, for people who use Unimogs for things other than just looking like crazy survival enthusiasts, a new transmission feature makes it possible to activate engine-powered attachments without first stopping the vehicle. We're sure that's very useful for someone.
