The M133 is a turbocharged inline-four engine produced by Mercedes-Benz. Since its debut in 2013, it has been awarded International Engine of the Year three times in the "Best New Engine" and "1.8-litre to 2-litre" categories.[1]

Design

The M133 is based on the M270 engine but has been extensively revised by AMG.[2] It features a twin-scroll turbocharger, BlueDIRECT direct injection, iron-carbon alloy on the cylinder walls to reduce friction, and zircon in the cylinder heads to increase thermal conductivity.[3] The cooling system is also based on the one found in the Mercedes-Benz SLS AMG.[4] The M133 was updated in 2015, and features performance improvements of 20 kW (27 hp) and 25 N⋅m (18 lb⋅ft).[5]
