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

The instincts of many long-standing Mazda MX-5 owners might be to keep the mechanical specification of their car simple, and thereby to give the lauded delicacy of the car’s handling the best chance to thrive. We had the same instincts – hence the chosen specification of 1.5-litre engine, standard suspension, open differential and 16in wheels for our road test subject.

In reality, the MX-5’s handling doesn’t reward that judicious restraint in unqualified terms, in ways we’ll come to. But that shouldn’t prevent this car from taking its place among the most vibrant, responsive and engaging sports cars available at any price.

It's delicate and perfectly balanced, although the ride lacks some of the original's fluency

From the effortlessness of its hold on the road, through its fine balance and directional agility, to the zapping crispness of its every answer to a few extra degrees of steering angle or throttle, this car remains a true sporting great.

On delicacy, meanwhile, nothing short of a Caterham, Lotus or Ariel can equal what the MX-5 brings to the table. The car’s 195-section tyres produce only moderate but perfectly balanced grip levels and therefore don’t overburden the suspension or steering with cornering forces, and they break away into lateral slip with a wonderfully tender progressiveness.

Some testers found the electromechanical power steering overly light, while others appreciated that it is able to delicately convey information about the road surface and grip levels without adding unnecessary weight and stodginess. Generous angles of body roll introduce some softness in the handling mix under high lateral loads, taking some precision away – if only on the very edge of adhesion.

Despite the relatively soft suspension, the MX-5 can be a bit excitable over very high-frequency lumps and bumps, perhaps an inevitable result of the imperfect torsional rigidity of the convertible body, which doesn’t always let the suspension do its work. The 2.0-litre model seems to suffer slightly more from shimmies and scuttle shake, though.

The rest of the time the MX-5’s ride is easy and fairly laid back. Like that of its forebears, the directional keenness and poise come not from high chassis rates but from the advantages of even weight distribution, a low centre of gravity and driven rear wheels, and so the MX-5 doesn’t feel firm on the road or short of wheel travel. It doesn’t need to.

For a car that offers up as many thrills as the little Mazda does, it is remarkably habitable. The ride is rarely harsh and as long as you’re not too tall to fit, it offers a supremely comfortable driving position, legs outstretched but well supported. The MX-5’s one Achilles heel when it comes to comfort is the road noise. It seeps through the car’s every pore and resulted in a reading of 75dBA at 70mph. The hard-top RF does improve the motorway refinement.

The day of our performance tests with the 1.5 started wet but subsequently dried out. It therefore afforded us the opportunity to find out that the MX-5's delicate dry-surface grip level becomes even more tantalising when a bit of surface water is in the mix. In the wet, an uninterested driver might call that grip level worryingly faint, however, and the Yokohamas’ proclivity to hydroplane can be startling.

In the dry, there's only just enough power to get the rear wheels to break traction with the accelerator during cornering - and only then at very high revs and by a fleeting few degrees of slip angle. It's a tenderness of adjustability that you rarely find in a modern car and is no less enjoyable for its subtlety than a 500bhp Jaguar's handling is for its luridness. 

Disengage the ESP - a system that's fairly sophisticated so long as you don’t try to provoke the car - and there are familiar ways to have fun with your cornering line, either with a trailed brake or an exaggerated, throttle-off steering input. The MX-5 is sensitive to all. That being said, if on-throttle adjustability is key to your enjoyment of a rear-wheel-drive car, you’ll be much better served by the 2.0-litre, with its additional 51bhp and limited-slip differential. That is especially the case for 2024 model year cars, which get an upgraded differential and stability control system. In our experience, it seemed very slightly keener to yaw through bends, and the stability control's track mode lets you have some fun while still keeping an eye out.
