Powertrain - Smooth and Powerful

The powertrain for the Mazda CX9 was chosen specifically to support the vehicle's high quality look and feel with an exhilarating yet sophisticated driving experience. Under the bonnet is a new MZI 3.7-litre V6 petrol engine that produces 204 kW/273 HP (SAE-NET) of maximum power at 6,250 rpm, and a robust 366 Nm of torque at 4,250 rpm - making it the most powerful engine in the Mazda line-up.

This 60 short-stroke V6 has a die-cast aluminium block with cast-in iron cylinder lines and aluminium cylinder heads - for minimal weight and high durability - and it adds advanced engine technologies to optimally combine performance with acceptable fuel consumption. These include sequential valve timing (S-VT) for optimised engine torque at all speeds. It also has a high compression ratio of 10.3:1 and electronic throttle control, which helps provides instant response to pedal input for lots of driving fun. Two catalytic converters make sure the Mazda CX9 meets Euro Stage IV emission standards.

Yet despite its fun-to-drive nature, the MZI 3.7-litre V6 has low NVH levels for a crossover SUV. To achieve this, a highly rigid cylinder block is used to reduce engine vibration, the side frame engine mounts are reinforced to reduce transmission vibration, and the forged-steel crankshaft has a dual-mass damper for smooth operation. Camshaft vibration is kept to a minimum by the use of sprockets with rubber cushion rings, and the intake manifold is designed to reduce intake air undulation and resistance.
