Fourth-generation MX-5 heads back to Mazda's roadster's roots, surpassing its predecessor in every area

At the launch, Mazda’s engineers said that the 1.5 was the mechanical specification that shows the MX-5 at its absolute purest. So that is the version we chose to focus on when we road tested the ND originally. We've since driven every version, however.

In a modern context, the MX-5's engines are quite special – both the 1.5 and the 2.0 – because where else can you find an engine that spins so freely, and with gathering force, to its 7500rpm redline, short of much more expensive Porsches?

The longitudinal four-cylinder engine and RWD layout make for a perfect 50/50 front/rear weight distribution

For the 1.5, we’re not talking about a particularly quick full stride, although needing little over eight seconds to hit 60mph from rest, the car is appreciably faster than the 1989 original and close enough to hot hatch pace for respectability.

And yet this MX-5 plays perfectly to arouse your excitement and seize your enthusiasm as a willing hostage. It hardly matters how fast you’re going.

The temptation starts with an unexpectedly rorty exhaust note, which sounds playful and offbeat even at idle. Blip the accelerator out of gear and the revs flare with promising urgency, then engage first and the MX-5’s mechanically detailed and supremely positive shift quality announces itself. You’re already having an absorbing and special driving experience – and you’ve yet to even turn a wheel.

Gearshift aside, the car’s controls are light and, being so obliging to control, fairly short-geared and revving cleanly from very low revs, it moves away from a standstill with a pleasing lack of inertia. Add some throttle and you’ll pick up speed gradually at first, with limited mid-range torque on tap but with perfect response and a supremely linear delivery of it as the revs rise.

Get into a flow on a good road, or even an average one, frankly, and you’ll be revelling in the vivid mechanical interaction and the joy of taking a modern sports car to the redline as and when you choose without worrying unduly about the potential consequences for your driving licence.

There is no doubt that the 1.5 is sufficient for having a brilliant time in the MX-5, and we prefer it over the torquier but less effervescent 2.0-litre option that the ND launched with. However, the updated 2.0-litre engine that replaced it in 2018 mimics all of the 1.5’s character, and adds a substantial 51bhp and a limited-slip differential. The 1.5’s manual gearbox is a fraction sweeter to use, but the more powerful engine has become hard to pass up.
