New 2.2L MZR-CD turbodiesel for Mazda 6

The second generation Mazda 6 was initially offered with 120hp 1.8 liter, 2.0 liter and 170hp 2.5 liter petrol engines as well as a 2.0 liter turbodiesel producing 140hp.

Mazda has now replaced the diesel engine with a new 2.2 liter MZR-CD turbodiesel engine with a variable geometry turbocharger to the line-up, which comes in 3 states of tune - 125 PS with 310Nm of torque, 163 PS with 360Nm of torque and the most powerful of the entire European line-up which is the 185 PS version with 400Nm of torque.

The fuel injection pressure has also increased from the 2.0 liter engine’s 180 MPa up to 200 MPa, an improvement of 11%. The injectors now feature 10 spray holes per injector instead of the 6-hole design of the old engine.

0 to 100km/h takes 10.9 seconds, 9.2 seconds and 8.5 seconds respectively for each state of tune. As a comparison, the old 140hp 2.0 liter diesel did it in 10. 7 seconds. Depending on which version we’re talking about, the new 2.2 liter MZR-CD can return between 51.4mpg to 49.6mpg, and emi between 147g/km to 152g/km of CO2.
