Overview 

The 2020 Mercedes-AMG A45 S 4MATIC+ continued the momentum of its predecessor, solidifying its place as the modern-era "hyper-hatch". Under the bonnet, it features the hand-built M139 2.0-litre engine, which at launch remained the most powerful series-production four-cylinder in the world, delivering 421 bhp and 369 lb-ft of torque which provides a blisteringly quick 0–60 mph time of 3.9 seconds, aided by the eight-speed AMG Speedshift gearbox.

Driving the A45S, it’s clear that AMG have also worked their magic on the handling side. The 4MATIC+ all-wheel-drive system uses a sophisticated rear-axle differential with two multi-plate clutches. This setup enables "AMG Torque Control", which can distribute power individually to each rear wheel. The result is incredible cornering agility and the inclusion of the famous Drift Mode, allowing the car to behave like a rear-wheel-drive sports car when prompted.

For those who love luxury and technology, the A45S doesn’t disappoint, with a large 10.25-inch screen taking centre stage for the MBUX infotainment system that seamlessly integrates with the AMG instrument cluster, opening up a whole host of other technical wizardry. On the luxury side, the sports seats hold you tightly; a flat-bottom AMG steering wheel puts everything at your fingertips, including the ability to open the exhaust valves without taking your hands off the wheel.

This 2020 A45S 4MATIC+ comes from cherished, no-expense-spared ownership over three years, with a full service history and just 28,138 miles. This is the new era hot hatch, and with over 420 bhp from the factory, it really is something quite special.
