Unless you’ve been living under a rock for the past year, you’d know that Mercedes-AMG has introduced a new twin-turbocharged 4.0-liter V-8 engine that replaces its previous 6.2- and 5.5-liter mills. Code-named the M178, the engine delivers a maximum 503 horsepower at present, though we’re likely to see that figure dialed up considerably in the coming years.
