1.5-litre SKYACTIV-G engine

Enhanced for use in a lightweight roadster, Mazda’s highly efficient SKYACTIV-G petrol engines are a perfect match for the fourth-generation MX-5. With lighter and more compact intake and exhaust systems they are modified to deliver heightened performance. With revised cam timing and a custom steel crankshaft, the 1.5-litre 131ps SKYACTIV-G’s redline is raised to 7,000rpm and power output is improved over versions used in the Mazda2 and Mazda3. This engine offers a higher output than the outgoing 1.8-litre MX-5 at the same time as delivering far better fuel economy and lower emissions.

2.0-litre SKYACTIV-G engine

Specifically tuned for wider low and mid-range torque the 160ps 2.0-litre SKYACTIV-G engine is 8kg lighter than the outgoing MX-5’s MZR 2.0-litre engine. It also delivers more torque, quicker acceleration and far better fuel economy. As with the 1.5-litre engine, the 2.0-litre features lighter and more compact intake and exhaust systems, a dedicated lightweight flywheel, plus a lighter crankshaft and pistons. Both engines also feature an attractive and thin die-cast aluminium engine cover that weighs the same as a plastic cover but is visually reminiscent of early MX-5s.

SKYACTIV-MT manual transmission

Mazda’s highly-praised SKYACTIV-MT six-speed manual transmission has been adapted for front engine, rear drive layout for the first time. It maintains the same sporty 40mm shift stroke as previous MX-5’s, yet the SKYACTIV-MT is 7kg lighter than the six-speed unit in the outgoing MX-5. The rear differential is lighter and smaller than the outgoing car, while clutch pedal weighting and movement has been honed for an even better driver experience.

Steering

The Mazda MX-5 is the first MX-5 to feature a space-saving duel-pinion electric power assist steering system – replacing the outgoing MX-5’s hydraulic power assist set up. To deliver even more direct feedback and feel, Mazda’s engineers placed the steering system closer to the front wheels, while increased stiffness below the steering column improves linearity. Compared to the outgoing car the steering ratio has changed from 15.1 to 15.5 with the overall result being lighter, faster and more precise steering.

SKYACTIV-Chassis and SKYACTIV-Body

The lightest MX-5 since the first-generation, the Mazda MX-5’s SKYACTIV-Chassis is lighter, stiffer and more driver-focused than ever. Retaining a front double wishbone and rear multi-link suspension set-up, Mazda’s engineers worked to reduce weight and improve stability and agility. From the ground-up Mazda’s weight saving ‘gram strategy’ played a huge part in chassis development. The SKYACTIV-Chassis’ suspension is 12kg lighter than the previous model. The front knuckle, front upper and lower arms, engine frame and rear hub supports are all made of aluminium, while the use of more high-tensile steels and aluminium in the body-in-white further reduces weight.
