The redesigned Mercedes-AMG G 63 is coming with a serious power upgrade.
And yet it has a smaller engine. How did Mercedes manage this engine-witchcraft? This is a question the German manufacturer refuses to answer in plain English and instead spends many, many paragraphs saying exactly what they did to achieve this feat. You can read it, but be warned, you will need a master’s degree in mechanical engineering.
But let’s get to the details: the 2019 AMG G 63 comes with a 4.0-L twin-turbo V8 engine powering a nine-speed automatic transmission that puts computer-controlled power to all four wheels. The studious among you will note that 4.0-L is a lot smaller than the preceding car’s 5.5-L V8. You may think this will result in a commensurate loss of power.
You would be wrong.
Despite the fact the engine sips 1.5 fewer liters of gasoline, it puts out nearly 50 more horsepower. The previous G 63 had 537 hp, while the new one has 585 hp.
Using forbidden knowledge, Mercedes managed to make a smaller engine produce more power. Smaller engines are also more fuel efficient and produce fewer emissions—both good things. Both mandated things in Europe, so don’t exactly credit Mercedes with environmental altruism.
Especially when you discover the new G 63’s mileage, which is 17.8 mpg. Compared to a Civic that’s abysmal but compared to last year’s model that’s a nearly 75 percent increase in fuel economy, which is astounding.
The smaller engine helps, but even more helpful is AMG’s Cylinder Management system which simply turns off half the cylinders when you don’t need them (ie. cruising down the highway). Off-road you’ll get all eight cylinders going, but puttering around town not so much.
The G 63 will have even more exciting technology, like AMG Ride Control that dynamically controls suspension dampening, and Dynamic Select which allows the driver to select eight different driving options: “Slippery,” “Comfort,” “Sport,” “Sport+” and “Individual” on road, and “Sand,” “Trail” and “Rock” off-road.
This off-road SUV manages a 0-60 time of 4.5 seconds and tops out at around 150 mph.
The G 63 will make its world debut at Geneva next month.
