Engine Specs and Performance

The Mercedes-AMG GT 43 4-Door houses a potent 3.0-liter inline-6 turbocharged engine. Now, some of you might be thinking, "Just a six-cylinder?" But trust me, this isn't your run-of-the-mill six-pot. AMG has worked their magic to extract an impressive 362 horsepower and 369 lb-ft of torque. That's enough to propel this stylish four-door coupe from 0 to 60 mph in just 4.8 seconds. And it doesn't stop there; the GT 43 can reach a top speed of 168 mph, making it a serious contender on both the track and the open road.

But the numbers only tell part of the story. The real beauty lies in how this power is delivered. The engine is incredibly responsive, thanks to the turbocharger and the electric auxiliary compressor. This ensures minimal turbo lag, providing instant power when you need it. Whether you're overtaking on the highway or carving through winding roads, the GT 43's engine delivers a thrilling and engaging driving experience. Furthermore, the engine is mated to AMG's SPEEDSHIFT TCT 9-speed automatic transmission, which offers lightning-fast gear changes and multiple driving modes to suit your mood.
