Used Mercedes A45 AMG for sale

The Mercedes A45 AMG is one of the most exciting hot hatches out there – known for its speed, clever technology and sharp looks.

Used Mercedes A45 AMG

Blending high performance with practicality, you'll get the best of both worlds with one of these. The A45 AMG was first launched in 2013 as the most powerful version of Mercedes’ A-Class hatchback range, setting new benchmarks for hot hatch performance. Over time, it’s become famed for its explosive power, four-wheel drive grip and up-to-date safety tech. The latest generation, the A45 S, introduced in 2019, takes things even further, offering over 415bhp from its turbocharged 2.0-litre engine. Compared to rivals such as the Audi RS3 and BMW M2, the A45 AMG stands out for its mix of stunning performance, everyday comfort and Mercedes refinement. Recent updates have kept tech and safety levels topped up, making used models especially desirable for buyers who want a sporty car that’s safe and practical too.

Pros

  • +Explosive performance
  • +Advanced safety features
  • +Everyday practicality

Cons

  • -Firm ride for UK roads
  • -Expensive to buy and run
  • -Rear space is limited
  • What are the key safety features of the Mercedes A45 AMG?

    All generations of the Mercedes A45 AMG come loaded with safety gear, including multiple airbags, advanced stability and traction control, active lane keeping, blind spot assist and a pop-up bonnet for pedestrian safety. The car shares its five-star Euro NCAP rating with the regular A-Class, which is regularly praised for its crash protection and driver assistance systems.

  • What engine options are available with the Mercedes A45 AMG?

    Earlier models (2013–2018) use a 2.0-litre turbocharged four-cylinder engine, producing between 355bhp and 376bhp after a 2015 update. The current A45 S, launched in 2019, delivers 415bhp from an upgraded version of this engine, making it the most powerful four-cylinder hot hatch on sale. All versions are paired with an advanced automatic gearbox and four-wheel drive.

  • What are the standard technology and infotainment features in the Mercedes A45 AMG?

    High-spec infotainment comes as standard, featuring large digital instrument displays, a prominent touchscreen with Mercedes’ MBUX system, Bluetooth, smartphone integration and a premium surround sound system. Advanced navigation, wireless charging and customizable ambient lighting are all available, especially on more recent models. Earlier versions still feature advanced connectivity, albeit with smaller screens and less software finesse.

  • What is the fuel consumption of the Mercedes A45 AMG?

    Given its performance, the A45 AMG is reasonably efficient. Older models officially return up to 40.9mpg, though you should expect less in real-world UK driving. The latest A45 S achieves around 31mpg (WLTP), so running costs are higher than a standard hatchback, especially when used enthusiastically.

  • What should I check when buying a used Mercedes A45 AMG?

    Check for a full service record, signs of hard use and any warning lights. Early cars may develop issues with their gearbox or infotainment system. Ensure the four-wheel drive system works properly. Consider a professional check like The AA Vehicle Inspection, which is especially useful for high-performance models such as this.

  • Are Mercedes A45 AMG cars reliable?

    The A45 AMG has a solid reliability record compared to other high-performance cars, but running costs can be high and some models have reported minor electrical or trim problems. Regular maintenance is key, and most owners find the manual and warranty support helpful. Reliability improves with newer models, but as with any sporty car, previous owner care makes a big difference.
