As a constant companion for high-performance driving, the Mercedes-Benz A45 AMG is equipped with a 2.0-liter four-cylinder turbocharged engine, codenamed M139, delivering 416 horsepower and 500 Nm of torque, paired with an 8-speed dual-clutch transmission, achieving 0-100 km/h acceleration in under 4 seconds. The design highlights include an electronic turbo to reduce lag, compact integration of twin-scroll technology, offering strong burst power without rapid heat degradation. In daily driving, gear shifts are smooth, and the initial acceleration provides a strong push, but it requires 98-octane gasoline. Compared to the Audi RS3 engine, the A45 AMG's tuning is more aggressive and linear, with maintenance costs that aren’t excessively high—just regular upkeep is sufficient. For those looking for a hot hatch, this engine is reliable and thrilling, perfect for enthusiasts seeking driving pleasure, with ample room for modifications.

My buddy has been driving an A45 AMG for years, and that 2.0-liter turbocharged engine is truly impressive. The roar when starting up is exhilarating, and it unleashes its power when you floor the throttle, making acceleration a blast. It's steady for daily commutes, idles smoothly even in city traffic jams, and averages around 9 liters per 100 km on highways, though it climbs to 12 liters in Sport mode—worth the extra fuel cost. The engine is highly reliable; he's had no major issues with regular 10,000 km maintenance, and the transmission responds sharply. Compared to older models, the new engine is quieter, with less noise after cold starts, so it doesn't disturb kids sleeping in the car. Occasionally, a minor exhaust mod makes it even cooler. Overall, it’s perfect for city driving and weekend speed runs.

The Mercedes-Benz A45 AMG features a 2.0-liter four-cylinder turbocharged engine, delivering 416 horsepower, a significant increase over the previous M133 engine, with faster response. Compared to its rivals, its exhaust note isn't as deep as the BMW M2's inline-six engine, but it accelerates quicker; the Audi RS3's five-cylinder engine has slightly weaker low-end torque, while the A45 AMG excels in mid-range acceleration. It's easy to drive daily, with tuning that balances comfort and aggressive output, and optimized fuel consumption under 10 liters per 100 km. Maintenance is straightforward, with some issues manageable at regular repair shops, making it both hassle-free and cost-effective.
