2019 Mazda MX-5 to score major power boost

Mazda's MX-5 Roadster scores a new "caramel" roof in Japan

Mazda’s iconic roadster is set for a significant power boost, with reports out of Japan confirming the MX-5’s pair of engines have been overhauled to produce more oomph.

Mazda's Japanese website confirms a 2019 update (actually on sale July 26 in Japan) will see minor changes to the brand's 1.5-litre engine, with the MX-5’s smallest motor tweaked to produce 97kW and 152Nm, up from 96kW and 150Nm in the current model.

But changes to the 2.0-litre engine are more significant, with power boosted to around 135kW and 205Nm - up from the current model’s 118kW and 200Nm. New lightweight pistons, a larger throttle body and new exhaust valves have helped achieve the gains, with most of the new power delivered near the top of a revised redline, increased from 6800rpm to 7500rpm. Reports also suggest the suspension has been tweaked to produce better steering feel.

"The torque was improved in the whole revolution range, while the output performance was increased by 15 per cent or more in the high revolution range. The maximum revolution number was raised from 6800rpm to 7500rpm. Furthermore, it improved the performance of the engine itself dramatically, such as improving fuel economy and environmental performance," a description of the changes to the 2.0-litre engine reads.

Mazda is also promising a new and louder engine sound that is "suitable for a high performance engine", with the upgrades to be offered in both the MX-5 and RF models. In Japan, the 2019 changes also see an improved safety offering, a new black wheel colour and the option of a "caramel" roof.

The new engines will be offered in Japan from July 26, but Mazda Australia spokesperson Sonia Singh says the changes are yet to be confirmed for local versions. That said, Mazda in Australia - one of the brand's biggest international markets - are sure to be very keen to offer the newest and most powerful engine range available.
