Part of the eco-evolution of Mazda powertrains includes the introduction of a unique catalyst developed by Mazda for its petrol engines. Traditional catalysts have precious metals that cause chemical reactions on their surfaces that purify exhaust gases. Because these metals are bonded to a base material, they tend to clump into larger particles over time, which reduces their ability to purify exhaust gases. To compensate for this problem, catalysts have traditionally used large amounts of precious metals. Mazda solved this problem by successfully embedding precious-metal particles in the catalytic base material that are nano-sized (< 5 nm) for the first time ever. These particles remain in place during long periods of exposure to high exhaust heat, which retains an effective surface area for purifying gases. Not only does Mazda's unique single-nano technology catalyst help petrol engine efficiency, it needs about 72 percent fewer precious metals, which preserves these rare natural resources and limits the cost of production.

MZR 2.5 Petrol - An Exclusive Driving Experience

The top-of-the-range MZR 2.5 petrol produces 125 kW/170 PS of maximum power at 6,000 rpm and 226 Nm of torque at 4,000 rpm. With a high-rigidity block, two balancer shafts, a dual-mass damper and a flexible flywheel this engine develops its power in a smooth, cultivated way. Under the bonnet of the new Mazda 6 facelift, this engine delivers a truly premium driving experience. Its compact size and light weight, along with fuel-optimizing technologies like sequential-valve timing (S-VT) and a variable intake system (VIS), maximize power delivery and torque across the speed range, while keeping fuel consumption to a minimum. Aerodynamic upgrades, revised gear ratios and powertrain control module (PCM) have reduced consumption slightly (0.1 litre per 100 km less), while chassis updates make it more stable while cruising; something this engine is very good at. It features the new single-nano technology catalyst and meets Euro Stage V emission standards.

MZR 1.8 Petrol - Now even more Frugal at the Pump

The MZR 1.8 petrol with five-speed transmission is a great combination of lively power and low consumption. With electronic throttle control, it delivers great drivability, and its VIS optimises the charging effect in the intake manifold according to engine speed by varying the length of the intake passages to ensure optimum power delivery throughout the rev range. It produces 88 kW/120 PS at 5,500 rpm, and 165 Nm of torque at 4,300 rpm, but has revised gear ratios to use less fuel than the current engine (approx. 6 percent less in the hatchback).
