Mercedes-Benz is set to introduce an AMG variant of the GLK when the off-roader receives its next-generation iteration in the next couple of years. Now the model has been spied testing for the very first time with a host of details about its engine also emerging.
Under the hood, the 2016 Mercedes-Benz GLK63 AMG will utilise the firm’s new 4.0-litre twin-turbo V8 engine set to underpin the Mercedes-AMG GT and next-generation C63 AMG. Dubbed the M178, this engine will replace the current twin-turbocharged 5.5-litre V8 used by much of the AMG range.
In range-topping Mercedes-AMG GT S specification, this engine delivers 503 hp. However, that figure can be conceivably increased by quite some margin for those models requiring an extra oomph like the GLK63 AMG. As a matter of fact, Car and Driver says that almost every rear-wheel drive platform based AMG will utilise this engine including the S63 AMG, ML63 AMG and next-generation E63 AMG.
