The Mazda MX-5 is entering a new chapter in the UK, and it is a bittersweet one for fans of lightweight sports cars. Mazda has confirmed a modest power increase for the 1.5-litre MX-5 just as the more powerful 2.0-litre version disappears from the British market.
For the updated model, the naturally aspirated 1.5-litre four-cylinder engine now produces 134bhp and 114lb-ft of torque. That represents an increase of 4bhp and 3lb-ft over the outgoing engine. The numbers are hardly transformative, but Mazda insists that the changes are about more than simply chasing peak output.
The bigger story is what has been lost. The 2.0-litre MX-5, which produced 181bhp and 151lb-ft, is being phased out of the UK because of increasingly stringent emissions regulations. Existing cars will continue to be available until remaining stock is exhausted, with Mazda UK expecting that to happen around January.
That leaves the 1.5-litre as the sole engine choice for buyers seeking a new MX-5 in the UK.
Mazda Says the 1.5-Litre Is the Engine the MX-5 Was Designed Around
While losing the 2.0-litre engine will disappoint enthusiasts who value outright performance, Mazda is keen to point out that the smaller engine has always been central to the character of the current-generation MX-5.
The company says the 1.5-litre engine’s combination of low weight, responsiveness and accessible performance better represents its Jinba Ittai philosophy—the Japanese concept of creating a close connection between horse and rider.
That philosophy has been fundamental to the MX-5 since the original model arrived in 1989. Rather than relying on huge horsepower figures, the roadster has traditionally focused on low weight, agile handling, rear-wheel drive and driver involvement.
The updated 1.5-litre engine continues that formula, albeit with a little more muscle.
Mazda has also revised the engine’s sound in an effort to make the car feel more engaging from behind the wheel. At the same time, CO2 emissions have been reduced by 1g/km.
Mazda MX-5 Gets Chassis Upgrades
The biggest hardware change may not be under the bonnet.
The range-topping Homura and Homura Plus versions of the 1.5-litre MX-5 will now receive Bilstein dampers and a front strut brace. These components were previously associated with the more powerful 2.0-litre model.
The upgrades should give the 1.5-litre roadster a more focused chassis, with improved body control and sharper responses when the road starts to twist.
For enthusiastic drivers, that could make the reduced engine output easier to accept. The MX-5 has never needed huge power to be entertaining, and a lighter engine combined with upgraded suspension could preserve much of the car’s appeal.
There is, however, one significant omission.
The 2.0-litre MX-5’s asymmetrical limited-slip differential will not be carried over to the 1.5-litre version. That differential was one of the features that helped make the larger-engined MX-5 particularly attractive to drivers who wanted to exploit its rear-wheel-drive chassis.
As a result, the 1.5-litre may gain some of the 2.0-litre’s chassis hardware, but it will not become a direct replacement for the outgoing performance model.
The 2.0-Litre Mazda MX-5 Is Leaving the UK
The disappearance of the 2.0-litre engine is ultimately being driven by emissions regulations rather than a sudden change in Mazda’s opinion of the engine.
According to Mazda UK, the 2.0-litre MX-5 was already removed from European markets in 2024 because of changing emissions requirements. The UK was able to continue selling the model for longer because of different regulatory derogation timings.
That extension has now ended.
Once the remaining 2.0-litre cars are sold, British buyers will no longer be able to order a new MX-5 with the 181bhp engine.
For a car that has built much of its reputation around mechanical simplicity and driver engagement, the change illustrates the growing difficulty of keeping relatively low-volume sports cars compliant with increasingly demanding emissions rules.
Mazda MX-5 Price and Availability
The updated 1.5-litre Mazda MX-5 is scheduled to arrive in the UK in January, although Mazda has yet to announce its pricing.
The company has nevertheless stressed that affordability remains an important part of the MX-5 formula. Mazda says the roadster is one of only three convertibles available in the UK for less than £30,000.
That positioning is increasingly significant in a market where affordable two-seat sports cars have become rare.
The MX-5 remains one of the few cars that offers a traditional sports-car recipe—front-mounted engine, rear-wheel drive, two seats, manual transmission and a folding roof—without moving into premium-car pricing.
Is the Mazda MX-5 Still Relevant?
The MX-5’s future is not completely guaranteed.
The current generation is now more than a decade old, and sales in the UK have declined considerably. Around 4,000 examples were sold in 2019, while annual volumes have subsequently fallen to roughly 1,500 cars.
That makes the MX-5 an increasingly unusual proposition in Mazda’s line-up. It is effectively the brand’s halo model, but it operates in a shrinking segment and uses a platform that has been around for many years.
Nevertheless, the MX-5 continues to have something that many modern performance cars have lost: simplicity.
There is no need for hundreds of horsepower, an enormous battery or an elaborate all-wheel-drive system to make the MX-5 entertaining. Its appeal comes from how little car the driver has to manage.
That is also why the 1.5-litre engine could prove to be more than merely a consolation prize for buyers who can no longer have the 2.0-litre.
The 1.5-Litre MX-5 May Be the Purist’s Choice
On paper, dropping from 181bhp to 134bhp looks like a substantial step backwards. There is no getting around the fact that the 2.0-litre MX-5 is considerably faster and has more performance potential.
But maximum power has never been the only measure of an MX-5.
The 1.5-litre engine’s lower weight helps preserve the roadster’s lightweight character, while the additional chassis hardware on higher-specification models could make the updated car even more enjoyable on a winding road.
In an era when sports cars increasingly depend on enormous outputs and sophisticated electronic systems, the MX-5 continues to make a different argument: less can be more.
That makes the updated 1.5-litre particularly interesting. It may not replace the 2.0-litre as the ultimate MX-5 for outright performance, but it could remain the model that most faithfully represents Mazda’s original philosophy.
A Fitting Evolution for the Mazda MX-5
The end of the 2.0-litre MX-5 in the UK marks the end of an important chapter. Its 181bhp engine, rear-wheel-drive layout and limited-slip differential made it one of the most compelling affordable sports cars still available.
But the 1.5-litre MX-5 is not simply being left behind.
With 134bhp, improved engine sound, slightly lower CO2 emissions, Bilstein dampers and a front strut brace on the Homura and Homura Plus trims, Mazda is giving its smallest engine a meaningful update while preserving the qualities that have defined the MX-5 for decades.
Whether that will be enough to keep the MX-5 relevant in the UK remains to be seen. What is certain is that the affordable, lightweight roadster is becoming an increasingly rare species—and that makes the Mazda MX-5 more important than ever.
