It's a testament to AMG's commitment to pushing boundaries, transforming an already formidable compact into something truly extraordinary.

The journey began with a bold step for Mercedes-AMG, venturing into the compact class in 2013 – a completely new market segment for the high-performance division. This audacious move proved incredibly successful, with compact AMG models quickly becoming a compelling success story. Their sporty, exciting driving experience, coupled with an emotionally captivating design, resonated deeply with dynamic and individualistic drivers, drawing new customers to the sports car brand. But as Tobias Moers, Chairman of Mercedes-AMG GmbH, aptly put it, "We never rest on our laurels, but constantly strive to develop our products further." The A45, despite its initial triumph, possessed untapped potential that AMG felt compelled to unlock, driven by their unwavering brand claim.

Unleashing Unprecedented Power: The AMG 2.0-Litre Turbo Engine

At the heart of the 2016 Mercedes-AMG A45 4Matic lies a masterpiece of engineering: the turbocharged AMG 2.0-litre four-cylinder engine. This remarkable power unit once again asserts its dominance, producing a peak output of 280 kW (381 hp) and a maximum torque of 475 Newton metres. This significant power upgrade means the A45 remains the world's most potent and dynamic compact sports model, accelerating from a standstill to 100 km/h in a blistering 4.2 seconds – a full 0.4 seconds faster than its predecessor. Crucially, this enhanced performance is achieved while maintaining the previous model's exemplary fuel consumption, registering an NEDC figure of 6.9 litres per 100 kilometres, a class-leading achievement for a high-performance vehicle.

The engine's astounding output of 141 kW (191 hp) per litre sets a new record for a series production four-cylinder engine, placing this high-performance AMG power unit on par with thoroughbred super sports cars. This power surge was primarily achieved through a newly configured valve assembly and optimised combustion processes, benefiting from reconfigured timing and turbocharging. The maximum charge pressure remains at 1.8 bar, showcasing efficient boost management.

High-Tech Components and Award-Winning Pedigree

The AMG 2.0-litre turbocharged engine boasts an array of sophisticated high-tech features. Spray-guided direct petrol injection, utilising piezo injectors centrally located in the four combustion chambers, injects fuel at pressures up to 200 bar. This, combined with multiple fuel injection and multi-spark ignition, enhances fuel economy and significantly boosts thermodynamic efficiency, resulting in commendably low exhaust emissions. A twin-scroll turbocharger and maximum dethrottling of the exhaust system contribute to improved charge pressure build-up, ensuring the engine responds instantly to accelerator inputs.

Further highlights include a gravity sand-cast all-aluminium crankcase, a weight-optimised crank assembly with forged steel crankshaft and forged pistons, friction-optimised piston rings, and advanced NANOSLIDE® cylinder wall technology. Alternator management and the ECO start/stop function underline its efficiency credentials. Furthermore, sophisticated cooling systems for the engine oil, coolant, charge air, and transmission fluid not only extend durability but also ensure robust suitability for demanding track use. The excellence of this four-cylinder powerhouse has been widely recognised, earning the coveted "International Engine of the Year" award in the 1.8 - 2.0 litres displacement class in both 2014 and 2015.

The AMG SPEEDSHIFT DCT 7-speed Sports Transmission

Complementing the engine's prodigious power is the AMG SPEEDSHIFT DCT 7-speed sports transmission, crucial for agile and dynamic power transfer. The 2016 model benefits from shorter transmission ratios in 3rd to 7th gear, providing even more dynamic acceleration across all speed ranges. Optimised response and shift times, combined with a closer ratio spread, ensure seamless transitions during upshifts. The control logic for the RACE-START function has also been simplified, allowing for maximum acceleration from a standstill, accompanied by an emotionally stirring acoustic experience. The transmission also features a temporary M mode, activated by the steering wheel shift paddles, and a full manual transmission mode for individual gearshifts.

Tailored Driving Experience: AMG DYNAMIC SELECT

Borrowed from the Mercedes-AMG GT and C63, the new AMG DYNAMIC SELECT driving modes offer the widest possible selection of driving dynamics in the A45. Drivers can choose from four core modes: "Comfort", "Sport", "Sport +", and "Individual". These modes, selected via the AMG DYNAMIC SELECT Controller on the centre console, modify parameters such as engine and transmission characteristics, exhaust note, and ESP® settings.

• Comfort Mode: Geared towards consumption and comfort, with a subdued engine note and gentle gearshifts. Features a new 'sailing' function (60-160 km/h) for fuel saving and active ECO start/stop.
• Sport Mode: Emphasises agility and driving pleasure with a sporty engine and transmission setup. The turbocharged engine delivers a throatier sound. ECO start/stop and sailing functions are inactive.
• Sport + Mode: For even more immediate power transmission. The transmission's shift strategy is optimised for very sporty driving, including extremely short shift times, emotional double-declutching, and faster accelerator responses. Partial cylinder suppression further speeds up gear changes.
• Individual Mode: Allows customisation of individual parameters for the engine, manual or automatic transmission mode, and the 3-stage ESP®.

All DYNAMIC SELECT modes are vividly visualised in the cockpit display, with special icons and information in the central display. A pop-up window on the free-standing central display provides animated graphics and colour presentations corresponding to the chosen mode – from subdued blues in "Comfort" to a racetrack graphic in "Race" mode.

Sharpening Dynamics: AMG DYNAMIC PLUS Package and RIDE CONTROL

A completely new offering for the Mercedes-AMG A45, the AMG DYNAMIC PLUS package significantly sharpens vehicle dynamics, drawing direct influence from Mercedes-AMG's motor racing successes. A major component is the newly developed, mechanical front axle locking differential, which profoundly improves traction during sporty driving, especially when accelerating rapidly out of bends. This allows for maximum grip and high rates of lateral acceleration, while also stabilising the A45 more effectively during load changes and at high speeds.

The AMG DYNAMIC PLUS package also includes the AMG RIDE CONTROL sport suspension, featuring two-stage, adaptive damping adjustment. This system automatically adapts damping forces for each wheel based on driving situation and road conditions, operating infinitely variably within milliseconds. Drivers can also preselect basic damping characteristics in two stages for a personalised setup – choosing between maximum sportiness or pronounced long-distance comfort at the touch of a button. This suspension is also available individually as an optional extra.

The speed-sensitive sports power steering supports a sporty driving style with high precision and direct self-steering characteristics, offering two different sets of characteristics depending on the selected damper setup. The fifth DYNAMIC SELECT driving mode, "Race", is included with the AMG DYNAMIC PLUS package and the AMG RIDE CONTROL sport suspension. This mode configures the A45 4Matic for fast laps on the racetrack, with even more immediate engine and accelerator response. It sets 3-stage ESP® to "SPORT HANDLING MODE" for wider drift angles and activates a transmission "Race" mode configured to maintain optimum engine speed in the lowest possible gear for racetrack speeds.

Uncompromising Traction: AMG Performance 4Matic All-Wheel Drive

Dynamism, agility, and performance are hallmarks of the standard AMG Performance 4Matic all-wheel drive system in the A45. It masterfully combines optimal traction with outstanding driving pleasure. Suited to dynamic handling requirements, the A45 4Matic features infinitely variable torque distribution, ranging from front-wheel drive only to a 50:50 split between the front and rear axles. This variability, precisely tailored to the driving situation, ensures an optimum balance of dynamism, efficiency, and traction in the compact class. A multi-disc clutch with AMG-specific electro-hydraulic control, integrated into the rear axle differential, almost instantly feeds engine torque to the rear wheels when needed.

Factors influencing torque distribution include vehicle speed, lateral/linear acceleration, steering angle, rotational speed differences between wheels, selected gear, and accelerator position. The all-wheel drive system is also controlled in conjunction with the selected stage of 3-stage ESP®, ranging from safety-focused to maximum performance on closed-off racetracks. Furthermore, ESP® Curve Dynamic Assist is standard, creating a defined yawing moment about the vertical axis during dynamic cornering through imperceptible braking intervention on the rear inside wheel. The result: the Mercedes-AMG A45 enters bends responsively, precisely, and always controllably.
