Not supprising from the company putting AMG on everything.
In recent years, Mercedes has gone performance mad, fitting AMG badges on almost every model. In fact, AMG cars now account for one in every 10 cars the company sells. It may seem like every Mercedes model has an AMG counterpart, but there are a few models around the world that haven't been made faster by the AMG division. For starters, the X-Class pickup truck as Mercedes says a high performance luxury truck doesn't make sense. This still doesn't mean a faster X-Class isn't being considered.
In an interview with Drive, head of X-Class engineering Frank Schumacher said Mercedes is ready to upgrade the V6 diesel to beat the Volkswagen Amarok. "Yeah, there is always more [power to be extracted from its current engine to beat the Amarok] but that's if the requirements come from a marketing point of view and if customers want more power – [it's no different] with other platforms, we react to customers' wishes. If there will be wishes after the launch of the vehicle that says we need to have V8 then probably we will put in a V8, but that's always a response on customer request" he said. An AMG version may not be in the cards, but a detuned 4.0-liter twin-turbo could still happen.
The biggest engine currently found in the X-Class is a diesel V6 producing 255 horsepower. In models like the S560, the 4.0-liter V8 produces 463 hp, which would be a massive upgrade for the X-Class. We would love to see a V8 X-Class, but Mercedes doesn't seem so sure. "With a V8 you get out of the mid-size pickup but if you look at the market correctly most of the market is focused on the four-cylinder. A ute like that's a different size of vehicle, it is very limited to the US really - they will have their own market." Mercedes doesn't offer the X-Class in the US, but perhaps a V8 engine would make it more appealing for American buyers, enough for Mercedes to import it.
