Low Fuel Consumption

The Mazda CX-7 facelift with the MZR-CD 2.2-litre turbo diesel is not only exciting to drive, it's also frugal at the pump for such a sporty SUV with so much room and versatility. It needs just 7.5 litres of fuel per 100 km (combined) by employing a low compression ratio of 16.3:1 (for a compact SUV), a small turbo charger, improved intercooler efficiency and special gear ratios. It also uses highly responsive injectors that achieve a minimum injection interval of just 200 μs, which makes injection about 30 percent faster, and allows strict control over the amount of fuel used during injection.

Cleaner-Running and Euro Stage V Compliant

The MZR-CD 2.2-litre turbo diesel complies with Euro Stage V emission standards and is combined with the latest Mazda exclusive exhaust-gas treatment technology. Its newly-developed diesel particulate filter (DPF) is made from a ceramic material with high thermal resistance that includes a special Mazdadeveloped catalyst. The catalyst uses oxygen stored in the base material, in addition to the oxygen present in exhaust gases, to improve combustion of soot emissions. By increasing the volume of oxygen, this system makes regeneration of the filter faster and more efficient. In fact, Mazda CX-7 facelift's DPF needs to regenerate (in the NEDC mode) only half as often as conventional systems, and each regeneration process takes only a third as long. After exhaust gases have been purified of particulate matters, they pass through Mazda's newly-developed Selective Catalytic Reduction (SCR) system to significantly lower NOx.

MZR 2.3 DISI Turbo - The Original High-Performance Petrol

The petrol version of the Mazda CX-7 facelift inherits the original model's acclaimed MZR 2.3-litre DISI Turbo engine. Its direct-injection technology has a host of advantages over intake manifold petrol engines. Torque is about 10 percent higher at 3,000 rpm, because of the cooling effect caused by injecting petrol directly into the combustion chamber. For the Mazda CX-7 facelift, the DISI petrol is improved even further. Its piston crowns now have a dish-shaped cavity that improves the air-fuel mix and contributes to better combustion during engine warm-up. Fuel is now injected not only during intake, but also during the compression stroke for a richer mix around the spark plugs and increased combustion stability. The MZR 2.3-litre DISI Turbo produces 191 kW/260 PS at 5,500 rpm and a high maximum torque of 380 Nm at a low 3,000 rpm. It responds quickly to pedal movement, accelerates the Mazda CX-7 facelift in 8.2 seconds from 0 to 100 km/h, and allows a top speed of 211 km/h.
