Summary


The Mercedes-AMG CLA 45 is a high-performance version of the standard CLA model range, which is in turn based on the Mercedes-Benz A-Class hatchback. This is the second-generation line-up, which arrived in the UK in early 2020.

More powerful than the CLA 35, this saloon (which Mercedes calls a ‘four-door coupé’) and estate (‘shooting brake’) range now only includes one trim and engine option – the four-wheel drive CLA 45 S that provides 420hp and a 0-62mph sprint time of four seconds flat.

Like the highly-regarded A 45 hot hatch, the CLA 45’s impressive performance has struck a chord with the British automotive media. Evo‘s Antony Ingram explains that the car “covers ground with astonishing composure”, while the What Car? team concedes that “it’s pricey, but such talent comes at a cost.”

That said, “there’s far more to it than pure speed”, says Auto Express. The CLA 45 range has also been praised for its tech-laden interior and practicality, particularly its large boot.

However, if ferrying around the family isn’t on your daily to-do list, Car‘s Jake Groves concludes that you should probably look elsewhere for performance thrills. “Look at it purely like a hot hatch, and you might be able to get almost as much thrill from something half the price.”

As of January 2024, the Mercedes-AMG CLA 45 holds a New Car Expert Rating of B, with a score of 67%. It earns top marks from media reviews, as well as for its excellent safety rating. However, CO2 emissions are only average and running costs are very high.
