Following an earlier indication of a power bump for the 2019 Mazda MX-5, Japanese publication Car Watch has revealed details of the 2019 MX-5 ahead of its Japanese market launch later this month.

Headlining the raft of changes is the breathed-upon 2.0 litre Skyactiv-G naturally aspirated petrol engine, which will now produce 184 PS and 205 Nm of torque, while its rev limiter has been raised from 6,800 rpm to 7,500 rpm. That’s significant gains over the current car‘s 158 hp and 200 Nm of torque.

The higher RPM capability is supported by uprated valve springs, the pistons lightened by 27 grammes thanks to a shaved-down dome, while the valve reliefs have been repositioned closer to the edges of the piston skirts. The connecting rods also undergo some weight loss, shaving 41 grammes with a more compact design and bolts that are shorter and thinner.

Meanwhile, the crankshaft has been optimised, with revised placement of the counterweights. In terms of breathing, the engine gains a throttle body with a 28% larger opening for greater air intake, and the intake flow is further improved in terms of tumble flow and a larger valve diameter.

The piston updates allow for the increased air and fuel mixture to be safely combusted thanks to improved knock prevention, at the same time maximising thermal efficiency and minimising emissions. The exhaust valves have also been enlarged, and scavenge through a new exhaust manifold with larger runners towards a new muffler, the latter tweaked for less high-frequency noise.

Updates to the intake ports, pistons, fuel pump and injectors have also been reported for the smaller 1.5 litre Skyactiv-G engine available in Japan. Elsewhere, the MX-5 gets additional safety equipment including Smart City Brake Support, along with cosmetic updates including new interior and exterior colours. On the chassis side, the Japanese website also reports the use of softer rubber bushes in the rear suspension links.

Mentioned last, but certainly not least, particularly for taller drivers, is a new steering column which now adjusts telescopically for reach, in addition to rake (height). This allows for a 30 mm range of reach adjustment, which will offer scope for a wider variety of drivers to get comfortable in the car.

For some, the answer is Miata. What do you think of the changes, dear readers?
