Review

Technical Specification
Mercedes-AMG CLA 45 Shooting Brake

  • engine capacity: 1,991cc
  • number of cylinders: 4
  • power output: 385ps
  • bore x stroke: 83 x 92mm
  • compression ratio: 8.6:1
Recently revised to boast 25ps more power and 25Nm additional torque, Mercedes-AMG’s 2-litre turbocharged in-line four powerplant continues to be the benchmark in the 1.8- to 2-litre category, taking top honours for the third year in a row.

Originally derived from the Mercedes-Benz M270 family, AMG comprehensively revised almost every aspect of the donor engine to create the M133. But in the past 10 months, the high-performance four-cylinder has benefited from further key engineering revisions such as the fitting of a new valve assembly and tweaking the engine timing, both of which have allowed for the increased power and torque outputs.

AMG powertrain engineers have also made changes to the way the turbo operates, but maximum boost pressure remains set at 1.8 bar.

It was these key changes, along with the engine’s stunning power performance and typical AMG character, that again won over many judges.

“This is still the best and most enjoyable four-cylinder available,” explained jury member Natan Tazelaar, a freelance journalist from the Netherlands. “Not just because it is the most powerful, but because it makes the A/CLA/GLA AMG models both hilarious and unbeatable.”

The M133 pocket rocket propels the A-Class, GLA and CLA AMG racers to 100km/h (62mph) in little over 4.0 seconds – some 0.4 seconds faster than before the engine power upgrades. And this is all from a Euro 6-compliant engine, capable of delivering consumption levels as low as 6.9 l/100km (40.9mpg). AMG states that this has mainly been achieved by a very effective warm-up cycle, on-demand usage of the oil pump, stop/start functionality and twin-scroll turbocharging.

“The M133 is still an awesome and consistent ‘little’ performer that shows AMG passion can work intelligently in the modern world,” added Carl Cunanan from Calibre.

And freelancer Jens Meiners fully agreed, commenting, “AMG’s ‘half engine’ provides just incredible power for its displacement.”
