2024 Mercedes-AMG A 45 S 4MATIC+ – AutoMart Review
The 2024 Mercedes-AMG A 45 S 4MATIC+ is a true testament to Mercedes-Benz’s prowess in engineering and performance. This compact powerhouse redefines what a hot hatch can be, combining ferocious performance, advanced technology, and a touch of luxury. For automotive enthusiasts and potential buyers, the A 45 S 4MATIC+ stands out as a remarkable vehicle in its class, offering an exhilarating driving experience that is hard to match.

From the moment you lay eyes on the A 45 S 4MATIC+, its aggressive design and athletic stance make a bold statement. The front end is dominated by the Panamericana grille, flanked by sleek LED headlights that exude a menacing look. The sculpted hood, large air intakes, and aerodynamic elements highlight the car’s performance-oriented nature.
The side profile is equally striking, with pronounced wheel arches housing 19-inch alloy wheels that emphasize the car’s muscular stance. The rear is characterized by a sporty diffuser, quad exhaust tips, and a subtle roof spoiler, all contributing to the car’s aerodynamic efficiency and sporty aesthetic. The overall design is both functional and visually appealing, ensuring that the A 45 S 4MATIC+ looks as fast as it drives.
The heart of the A 45 S 4MATIC+ is a 2.0-litre turbocharged inline-four engine, the most powerful series-production four-cylinder engine in the world. It delivers an astonishing 416 horsepower and 369 lb-ft of torque, propelling this compact hatch from 0 to 100 km/h in just 3.9 seconds. The engine’s ferocity is matched by its advanced engineering, featuring a twin-scroll turbocharger and high-pressure direct injection to maximize performance and efficiency.
Paired with an 8-speed dual-clutch transmission, the power is delivered smoothly and rapidly to all four wheels through the 4MATIC+ all-wheel-drive system. This setup ensures exceptional traction and stability, allowing the A 45 S to handle various driving conditions with confidence. The AMG Performance 4MATIC+ system also includes a Drift mode, which distributes power predominantly to the rear wheels for a more playful and dynamic driving experience.

The driving dynamics of the A 45 S 4MATIC+ are nothing short of extraordinary. The suspension is finely tuned to provide a balance between comfort and performance. The adaptive dampers adjust in real-time to changing road conditions, offering a ride that is both comfortable for daily driving and firm enough for spirited drives.
The steering is precise and direct, providing excellent feedback to the driver. The brakes are powerful and responsive, ensuring that the car can be brought to a stop as quickly as it accelerates. The A 45 S 4MATIC+ feels incredibly agile, with minimal body roll and a level of responsiveness that makes every corner an exhilarating experience.
Step inside the A 45 S 4MATIC+, and you are greeted by a cabin that blends luxury with sportiness. High-quality materials, including leather, Alcantara, and carbon fibre, create an ambiance of refinement and performance. The sport seats offer excellent support and comfort, with adjustable bolstering to keep you firmly in place during aggressive driving.

The centrepiece of the interior is the MBUX (Mercedes-Benz User Experience) infotainment system, featuring dual 10.25-inch displays that serve as the digital instrument cluster and central touchscreen interface. The system is intuitive and user-friendly, offering voice control, navigation, and seamless smartphone integration with Apple CarPlay and Android Auto.
The A 45 S 4MATIC+ is also equipped with a host of advanced driver-assistance systems, including adaptive cruise control, lane-keeping assist, and active brake assist. These features enhance safety and convenience, making every journey more enjoyable and less stressful.
Driving the A 45 S 4MATIC+ is a visceral experience that engages all your senses. The engine’s growl is intoxicating, and the acceleration is relentless. The car’s ability to transition from a calm, composed cruiser to a ferocious performance machine is truly impressive.
In Comfort mode, the A 45 S offers a smooth and refined ride, ideal for everyday driving. Switch to Sport or Sport+ mode, and the car transforms, with sharper throttle response, firmer suspension settings, and a more aggressive exhaust note. The Drift mode adds an extra layer of excitement, allowing you to explore the car’s limits in a controlled environment.
In the highly competitive hot hatch segment, the A 45 S 4MATIC+ stands out for its unparalleled performance and luxurious features. While competitors like the Audi RS3 and BMW M135i offer strong performance and driving dynamics, the A 45 S’s combination of raw power, advanced technology, and premium interior give it an edge.
The Audi RS3 is known for its powerful five-cylinder engine and excellent handling, but it doesn’t quite match the A 45 S’s level of refinement and interior luxury. The BMW M135i offers a sporty driving experience and high-quality interior, but it falls short in terms of outright performance and technological sophistication.

The 2024 Mercedes-AMG A 45 S 4MATIC+ is a remarkable achievement in the world of high-performance compact cars. It combines breathtaking power with cutting-edge technology and luxurious appointments, creating a vehicle that is both thrilling to drive and comfortable to live with.
For those who demand the very best in a performance hatchback, the A 45 S 4MATIC+ is an outstanding choice. It not only meets but exceeds expectations, setting a new benchmark in its class. Driving the A 45 S 4MATIC+ is not just about getting from point A to point B; it’s about experiencing the joy of driving in its purest form, with every journey becoming an unforgettable adventure.
