Mazda kills the MX-5 2.0 in Britain, its last European market
How a one-tonne Mazda roadster lost an argument about fleet CO2
Britain was the last place in Europe you could order an MX-5 with the 184 hp 2.0-litre Skyactiv-G engine. From January 2027 you cannot. Mainland Europe lost that option in 2024, and the UK has now been brought into line.
Nothing about the car changed. What changed is the arithmetic Mazda has to satisfy before it is allowed to sell one.
Why the MX-5 2.0 survived two years longer in Britain
Mazda pulled the 2.0-litre from European price lists in 2024 on emissions grounds, and Britain kept selling it only because of different derogation timings, the kind of phrase that means something only in type approval. That extension has now expired.
"While it's a shame that changing legislation means we can no longer sell the 2.0-litre in the UK, the 1.5-litre engine remains at the heart of the MX-5," said Mazda UK managing director Jeremy Thomson, who noted the current car was developed around the smaller unit.
Thomson also confirmed Mazda holds enough 2.0-litre stock to meet expected demand until around January. The engine is not gone from British showrooms yet. It is gone from the order book.
Why 139 g/km of CO2 decided the MX-5 2.0's fate
Mazda quotes 139 g/km of CO2 for the 2027 MX-5, a reduction on the outgoing 1.5. On a single car that figure means nothing. Inside a fleet average it means everything.
Under the UK's Vehicle Emissions Trading Schemes Order 2023, the instrument that also carries the ZEV Mandate, a manufacturer must hold the average CO2 of its non-electric sales at or below its own 2021 baseline, or buy credits from a cleaner rival. The EU applies the same logic through Regulation (EU) 2019/631, whose car target is averaged across 2025 to 2027. Every variant has to earn its place in that average, and the 184 hp 2.0-litre sat well above the 1.5.
Mazda has little room: the 6e is its only European EV, and it arrived late. Porsche met the identical problem by joining XPeng's emissions pool to keep its petrol engines. Mazda deleted a four-cylinder from a car that weighs barely more than a tonne.
What the 2027 Mazda MX-5 gets instead: 136 hp and Homura trims
The 2027 MX-5 reaches showrooms in January with the 1.5-litre Skyactiv-G as its only engine, rising to 136 hp and 155 Nm, a small increase on both counts. Mazda has reworked the engine's acoustics rather than leave it to get on with the job.
Two grades arrive alongside it, taking the range to eight models across Roadster and RF. Homura and Homura Plus bring 16-inch black RAYS alloys, red Brembo front brakes, Recaro seats, Bilstein dampers and a front strut brace, offered on the 1.5 for the first time. The six-speed manual stays, and so does the new Zinc Green Metallic paint.
AutoNext Take
The frustrating part is not that the 2.0-litre is gone. It is that it was never the problem. A roadster that weighs barely more than a tonne, driven mostly on dry Sundays, is a rounding error in any manufacturer's carbon ledger, and deleting it shifts Mazda's fleet average by an amount no atmosphere will register. The rule is doing exactly what it was written to do, and the car it caught was the wrong one.
Buy the 1.5 anyway. It has always been the better MX-5 in the way that matters, because a car this light does not want power, it wants momentum you have to work for. Mazda knows it, which is why the next MX-5 is being engineered to a 1,000 kg target. Just be clear-eyed about why the choice narrowed today: not because Mazda saw the light, but because the spreadsheet did.
