Back in March we talked a bit about an NHTSA document that had turned up claiming that the Mazda MX-5 would get a bump in power to 181hp. We haven’t heard anything else about that rumored power bump until now. A publication called Car Watch in Japan has tested out a Japanese market version of the MX-5 this week.
According to that publication, the MX-5 has 181hp and a higher redline bumped up to 7,500 rpm. The extra power and rev limit required lots of work on the 2.0L engine under the MX-5’s hood. Specifically, things like lighter connecting rods, a revised crankshaft, and better valve springs are used.
Engine Enhancements and Performance
The enhancements to the engine are not just about increasing power but also about improving the overall driving experience. The lighter connecting rods reduce the engine’s internal weight, allowing it to rev more freely and quickly. The revised crankshaft helps in balancing the engine better, reducing vibrations and improving smoothness. Better valve springs ensure that the valves close more quickly and securely, which is crucial at higher RPMs to prevent valve float and maintain engine reliability.
These changes are significant because they show Mazda’s commitment to keeping the MX-5 competitive in the sports car market. The MX-5 has always been celebrated for its balance and handling, and these engine improvements ensure that it remains a joy to drive, whether on a twisty mountain road or a racetrack.
Additional Features and Market Expectations
The MX-5 is also tipped to get a telescoping steering wheel. This is a feature that many drivers will appreciate, especially those with shorter legs who prefer to lean the seat back. A telescoping steering wheel allows for a more customized and comfortable driving position, which can make long drives more enjoyable and less fatiguing.
None of the changes have been confirmed for the US market yet, but the power bump and increased redline are sure to come here. The US market is significant for Mazda, and they are likely to bring these enhancements to American shores to keep the MX-5 competitive against other sports cars like the Subaru BRZ and Toyota 86.
Moreover, the MX-5 has a loyal fan base in the US, and these improvements will likely be well-received. Enthusiasts are always looking for ways to get more performance out of their cars, and factory enhancements like these are often seen as more reliable and desirable than aftermarket modifications.
In addition to the engine and steering wheel updates, there are rumors of other minor tweaks and improvements. These could include updates to the suspension for better handling, new wheel designs, and possibly even some interior upgrades to keep the cabin feeling fresh and modern.
The MX-5 has always been about providing a pure driving experience, and these updates are in line with that philosophy. By focusing on the engine and driving ergonomics, Mazda is ensuring that the MX-5 remains a driver’s car first and foremost.
