A new five-speed automatic transmission with manual shift mode is introduced for the MZR 2.0-litre petrol engine, a first for the Mazda 5 line-up. It has a new torque converter that achieves an optimal balance between performance and fuel efficiency by reducing energy loss produced by slip, by employing a wide lockup range and acceleration slip control function. These features, combined with special tuning of the engine's electric throttle system, produce positive acceleration response in city driving and nimble passing on country roads and motorways.

Retained is the MZR 1.8-litre petrol with five-speed manual transmission from the outgoing model known for its agile, fun and frugal nature. It produces 85 kW/115 PS of power at 5,300 rpm and a maximum torque of 165 Nm at 4,000 rpm . Its needs just 7.6 litres of fuel per 100 km (combined), 0.3 litres or 4 percent less than before , and produces 8 g/km less CO 2 .

The MZR-CD 2.0-litre common-rail turbo diesel is retained as well. It comes in two power derivatives, a Standard Power version producing 81 kW/110 PS at 3,500 rpm and maximum torque of 310 Nm at just 2,000 rpm , and a High Power version producing 105 kW/143 PS at 3,500 rpm and robust maximum torque of 360 Nm at 2,000 rpm . Both versions use a variable-geometry turbocharger for maximum torque even at low engine speeds, ensuring lively pedal response, along with a dual-mass flywheel and common-rail multi- stage injection technology (with up to six injections per cycle) for smooth, nearly petrol-like operation. The efficiency of its exhaust gas recirculation (EGR) cooler has been improved for the Mazda 5 facelift. Both diesel derivates are equipped with a six-speed manual transmission as standard . They use just 6.1 litres per 100 km (combined), 0.2 litres or 3 percent less than the outgoing engine, and produce 162 g/km CO 2 , which is 11 g/km less . A diesel particulate filter (DPF) remains standard for both diesel versions.
