The Mazda5 features the stable, predictable and comfortable drive characteristics the family needs. Chassis systems are tuned to minimize roll movement despite the relatively tall body height and constantly changing load demands of varying numbers of passengers and luggage, while at the same time offering exhilarating performance that every driver will enjoy. The chassis, body and power-train are all products of extensive testing and development efforts aimed at delivering performance that makes driving more enjoyable along with handling stability, ride comfort, packaging and functionality that family and friends will find comfortable and easy to use. Features of the 2.0-litre MZR petrol engine include an aluminium-alloy cylinder block, lightweight pistons, low-tension piston rings, equal-length intake pipes, low-resistance air cleaner, high-flow intake ports, and Tumble Swirl Control Valve. The MacPherson struts in the front and multi-link suspension in the rear are specially tuned to ensure a comfortable and stable ride for passengers in all three rows of seats, while pleasing the driver with the right amount of rigidity, precision and linear handling stability. The four-wheel disc brake system with ventilated discs in the front and solid discs in the rear surpasses everything in its class to deliver positive response and ease of pedal operation along with unrivaled stability and control. Mazda's proven four-speed Activematic transmission is further refined to match the Mazda5's spirited performance, and to improve manoeuvrability around town as well as fuel economy at highway speeds. Mazda's own Electro Hydraulic Power Assist Steering (EHPAS) system modulates the amount of assist power to match driving conditions for a more natural feel to steering, and reduces power consumption to contribute to improved fuel economy. The latest in advanced analytic technologies were employed in developing a body with optimum aerodynamic performance. The result is improved handling stability and fuel economy when driving at highway speeds, as well as a quieter ride. The sash-mounted door mirrors are one more example of the Mazda5's functional beauty. The housing curvature, housing inclination and mounting thickness are meticulously designed for maximum aerodynamic efficiency.
