What engines are used in the Mercedes-Benz E-Class AMG?

The Mercedes-Benz E-Class AMG uses a total of three engines: a low-power version of the 3.0-liter twin-turbocharged engine, a high-power version of the 3.0-liter twin-turbocharged engine, and a 4.0-liter twin-turbocharged V8 engine. The model equipped with the low-power version of the 3.0-liter twin-turbocharged engine is the E43, which produces 401 horsepower and a maximum torque of 520 Nm, paired with a 9-speed automatic transmission. The model equipped with the high-power version of the 3.0-liter twin-turbocharged engine is the E53, which delivers 435 horsepower and a maximum torque of 520 Nm, also paired with a 9-speed automatic transmission. The model equipped with the 4.0-liter V8 twin-turbocharged engine is the E63 S, which boasts 612 horsepower and a maximum torque of 850 Nm, matched with a 9-speed automatic transmission.

I've always had a soft spot for the Mercedes-Benz E-Class AMG, its engine is truly captivating! It's powered by a 4.0-liter V8 biturbo engine, specifically the AMG-tuned M177 version, delivering a maximum power of 612 horsepower and torque exceeding 850 Nm, making the driving experience absolutely exhilarating. When I floored the pedal during the test drive, the rear-wheel drive provided an intense push-back feeling, especially thrilling when overtaking on the highway with its rapid response. The engine sound is deep and powerful, and the AMG-exclusive exhaust system makes every acceleration feel like a concert. On a related note, the AMG has a similar design in the C63, but the E63 is tuned to be more stable, making it more suitable for long-distance cruising. For maintenance, it's recommended to regularly check the cooling system to avoid turbo overheating. These high-performance engines have a long lifespan, but you need to be willing to invest in maintenance to keep them running smoothly.

As someone who frequently deals with Mercedes-Benz, I'm familiar with the details of the E-Class AMG engine: its core is the AMG M177 twin-turbocharged V8, with a 4.0-liter displacement, featuring intelligent direct injection technology, designed to reduce turbo lag issues. I've seen many owner cases where this engine performs reliably under high loads, but attention must be paid to the fuel system and spark plugs, with an oil change cycle of around every 10,000 kilometers. There's a noticeable slight engine vibration at startup, but AMG's sound insulation is well done, making it not feel noisy during daily driving. From related experience sharing, compared to the regular E-Class, this system has a lower failure rate, with stronger heat dissipation for key components like the turbo. Maintenance costs are moderately high, but performance output is stable, making it suitable for those who enjoy minor modifications for slight performance enhancements.

I've been driving this E-Class AMG for over two years, and what I love most is the engine: a classic 4.0L V8 biturbo that delivers power smoothly yet fiercely, with effortless acceleration in the city and no lag. Fuel consumption is slightly better than expected, averaging around 12L per 100km. In Sport mode, the rear-wheel slip sensation is fun when pushing it on the highway, but it guzzles fuel quickly. The engine's quietness in Comfort mode is pleasant, making long trips fatigue-free. AMG's 'One Man, One Engine' philosophy shines through in the hand-assembled quality, which is reliable. Related discussions mention the engine's sensitive feedback to road feel—subtle vibrations on bumpy roads are noticeable but acceptable. Maintenance every six months is a bit pricey, but it's worth it for the driving pleasure.
