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.
Design
The M133 is based on the M270 engine but has been extensively revised by AMG. 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. The cooling system is also based on the one found in the Mercedes-Benz SLS AMG. The M133 was updated in 2015, and features performance improvements of 15 kW (20 PS; 20 hp) and 25 N⋅m (18 lb⋅ft).
