The Mazda CX-30 engine line-up combines exhilarating performance with enhanced fuel economy and environmental friendliness. The powertrain line-up showcases the latest Mazda Euro 6d-TEMP Skyactiv-D diesel and Euro 6d Skyactiv-G petrol engines, including the revolutionary Skyactiv-X petrol engine.

The clean and efficient Skyactiv-G, Skyactiv-D and Skyactiv-X engines are available with a choice of six-speed Skyactiv-MT manual or six-speed Skyactiv-Drive automatic transmissions.

The clean diesel engine used in the Mazda CX-30 offers fuel economy combined with environmental credentials for outstanding driving performance. The Skyactiv-D 1.8 diesel engine (WLTP fuel consumption: 4.1-7.3 l/100km; CO2 emissions: 135-173 g/km)1 comes with a choice of six-speed Skyactiv-MT manual or six-speed Skyactiv-Drive automatic transmissions.

The Skyactiv-D 1.8 diesel engine’s ultra-high-response multi-hole piezo injectors equip this unit with Rapid MultiStage Combustion. The resulting combination of fuel economy, quietness and reduced exhaust gases delivers smoother, more robust performance and improved real-world fuel economy.

Rapid Multi-Stage Combustion uses multiple injections of fuel (up to six) in quick succession while the piston is at or near top dead center to generate a continuous burn with a shorter combustion period. Knock noise is reduced by precisely controlling the amount of fuel in each injection to avoid rapid changes in the heat release rate during initial combustion. Injecting the fuel at high pressure ensures a fine mist that promotes thorough premixing of fuel and air helps in achieving the seemingly contradictory aspects of a shorter combustion period and reduced knock noise.

The unit develops 116 PS at 4,000 rpm and maximum torque of 270 Nm at 1,600-2,600 rpm. It combines an average fuel consumption of 4.1-7.3 l/100 km (WLTP) with CO2 emissions of 135-173 g/km (WLTP).

Thanks to a newly developed control system and new technologies to reduce friction, Mazda’s i-Activ AWD fourwheel drive system delivers a refined and stable ride in any driving situation while also achieving real-world fuel economy almost on a par with a front-wheel drive vehicle.

Mazda’s evolved i-Activ AWD adds ‘four-wheel vertical load’ detection and works in harmony with GVC to control torque distribution between the front and rear wheels, enhancing traction and grip regardless of the driving scenario. It also significantly reduces overall mechanical loss and contributes to improved fuel economy.

Newly adopted friction-reducing technologies include a rubber damper inside the power take-off unit that greatly reduces fluctuations in input torque sent to the rear-wheel-drive unit, and a new setting that applies a slight difference in the deceleration ratio between the power take-off and rear differential. By quickly adjusting torque distribution only when necessary, the system features positive response and enhanced real-world fuel economy.

The rear differential reduces mechanical loss by adopting ball bearings and the use of low-viscosity oil, along with a design that stores oil in the upper part and supplies just the necessary amount where and when required. Acting in combination, these measures increase the precision of the AWD-control unit while significantly reducing overall mechanical losses.

At the beginning of a turn, the AWD system will maintain the existing front/rear torque distribution to prioritize better turning response through the GVC unit engine torque control. After the initial turn-in, the AWD system gradually increases the amount of torque sent to the rear wheels to realize neutral steering and more stable vehicle motion.

Harmonization with GVC also substantially improves rear torque response and linearity with respect to the driver’s accelerator inputs. When accelerating, more torque is distributed to rear tires where vertical load is increasing. When decelerating, more torque is delivered to the front wheels to maximize the traction performance of all four wheels. It also improves controllability, so the vehicle responds faithfully to the driver’s intentions when engaging in active steering.
