The Mazda MX-5 is still great fun, and more grown up in its third (NC) generation. For pure driving fun, little else gets close

Before the 1989 Chicago motor show, there was no mass-market sports car for motoring enthusiasts of average means.

There were hot hatches and mid-engined coupés, but the affordable roadster had vanished in the preceding decade. Then Mazda unveiled the MX-5 and, in a moment, the open sports car had a future.

Styling is a subtle evolution of the old car’s, with a hint of natty RX-8 detailing

The world’s most written about and, arguably, most desirable affordable car first arrived in Britain a year later, filling the void left by the old Lotus Elan. By 2000, the MX-5 had become the biggest-selling sports car of all time.

Such was the regard in which the second-generation model, produced between 1998 and 2005, was held, it was possible to overlook the fact that it shook and wobbled and wore a dated cabin. The charm of a basic, affordable roadster still prevailed.

By the time the Mk3 MX-5 was launched in 2005, buyers wanted more comfort and big-car refinement. To a large extent the MX-5 fulfilled that brief, even if weight had now grown to more than 1100kg (the original tipped the scales at less than 950kg; the Mk2 was a little over 1000kg).

Thankfully power increased too, and the range now encompasses 1.8 and 2.0-litre models, manual and automatic gearboxes and the choice of soft or folding hard-top models.

The 1.8-litre is only offered in the soft-top version, which incidentally weighs 80kg less than the hard-top Roadster Coupé, while the tin-top gets the option of the 2.0-litre motor and a wider range of trims.

Back to top

Those trims include the Sport Tech model, which gains Bilstein suspension and a front strut brace for a slightly more focused drive.

Mazda performed a tight, targeted facelift on its popular roadster in 2009, tackling initial customer criticism that ranged from the linearity of its steering to over-intrusive bottle storage arrangements.

At the 2012 Paris motor show Mazda launched a facelifted Mazda MX-5 to keep it fresh before an all-new model is introduced in 2014. The car is distinguished by a new front bumper and grille, while a new 'active bonnet' is fitted to improve pedestrian safety.

The question is, with the introduction of models such as the Toyota GT86, Subaru BRZ and BMW Z4, can the ageing Mazda MX-5 still cut it in the entertainment stakes?

DESIGN & STYLING

Look at the sales figures, furnished with the knowledge that each model was on sale for roughly eight years, and it’s clear that Mazda's original MX-5 was significantly more successful than its successor.

Of course, it had the market virtually to itself at first, and a small part of the original’s magic was lost in the transition to the Mk2. For this third-gen model, Mazda has therefore striven to recall the distinct flavour of its ancestor while offering the space, safety and durability of a thoroughly modern car.

Boot isn’t exactly large at just 150 litres, but it’s quite well shaped and will accommodate a couple of weekend bags

The latest model is bigger than its predecessor and is now 4020mm long, 1720mm wide and 1255mm tall (5mm more than soft-top models). Its wheelbase is 65mm longer than the Mk2, while the track is 75mm wider at the front and 55mm wider at the rear.

Underneath these smart clothes lies a conventional steel monocoque with structural use of high-tensile steels to improve safety and add stiffness, resulting in a 47 percent improvement in torsional rigidity.

Despite the increase in size and strength, Mazda claims the weight increase is minimal. Even so, the lightest models tip the scales at 1150kg, and with the folding roof and a 2.0-litre engine that increases to 1261kg. When the third-generation model launched, it weighed 1095kg – thank increased equipment levels for that.

But the weight could have been so much more: Mazda keeps weight gain to a minimum with its ‘gram strategy’ - engineers were asked to think up ways of saving weight throughout the car.

As well as detailed tinkering - simplifying the rear-view mirror saved 84g, for example - there are more fundamental measures: the bonnet, boot, engine sub-frame and suspension control arms are all made from aluminium, as is the engine.

A mid-life facelift in 2009 included a new front bumper that now houses Mazda’s signature five-node grille, consigning the Lotus-Elan-style elliptical intake of the old car to history. Revised suspension geometry brought about a significant lowering of the Mazda MX-5’s roll centre up front, which also helped reduce the car’s ride height.

For the 2012 update, Mazda focused on the throttle and brake systems. Changes to the former claim to offer the driver 'more control when accelerating from low speeds' whilst a retuned brake servo is said to 'optimise brake return control'.

INTERIOR

The new cabin is a major step forward from that of the previous Mazda MX-5. It’s not only the design and feel of the cabin, but also the fact that Mazda has engineered so much more room. The chunky gearlever is well sited and there’s plenty of clearance for your knees under the now height-adjustable wheel.

The seats offer decent support and visibility is improved, but it’s mainly the fact that you now sit lower in the car that makes the real difference.

The Mazda's headlights are good, but not exceptional

That said, tall occupants will notice the footwell’s lack of length and width. Some may also find it difficult to find a comfortable driving position, having to either choose between sitting at an odd angle or brushing their head against the roof.

Despite the improvements made in the fit and finish of the cabin plastics, they’re still a step or two behind the MX-5's admittedly far more expensive rivals. But there’s a surprisingly small gap between the quality of the Mazda's interior and that of the Toyota GT86 – a car introduced seven years after the third-gen MX-5.

Mazda's manual hood is exceptionally well thought-out and incredibly easy to operate – just release with the button near the rear-view mirror and fold it back. With the hood lowered, it’s clear that Mazda has worked hard to contain buffeting and noise levels. With it raised, the general refinement is acceptable, but on our test car, there was a tiresome droning from the back of the hood.

The Roadster Coupé’s folding hard roof takes up barely any more space than the MX-5’s soft-top, so there’s the same, 150-litre boot, roof up or down. It’s a superbly packaged mechanism, and a quick one at that. Twelve seconds might be about four times as long as it takes on a regular MX-5, but it annihilates its hard-roofed rivals. It’s noticeably quieter than the soft-top, too.

Refinement is acceptable in the Roadster Coupé, but there’s a degree of wind noise where the A-pillar meets the roof. Take a Roadster Coupé and a soft-top on back-to-back drives and the fabric-roofed model reveals considerably more noise. Both suffer from notable road noise intrusion, too, but not to an uncomfortable extent.

ENGINES & PERFORMANCE

As you drive off, you immediately feel more secure than in the previous Mazda MX-5 because this is clearly a stronger and more substantial car. But existing owners will appreciate the similarities, too, such as the eagerness of the engine and steering and the precision of the gearbox.

As ever, the Mazda demands intimate interaction right from the off. Curiously, it sounds very much like the old car, too, with the same tuneless mechanical-sounding engine note – but at least the exhaust burble from the two chunky tailpipes is engagingly sporty.

The MX-5 needs to be stretched, but there's a laudable amount of fun in doing so

The 2.0-litre is a 16-valve unit with 158bhp and it requires considerable stoking if you want to make rapid progress, even after the stronger bottom end that was included as part of the 2009 changes.

That’s no bad thing, but at times it feels flat lower down the rev range, and on hills and motorways it could use a little more torque.

At the top end, the engine feels nicely fluid, even on a test car with barely 3000 miles on the odometer. It’s here that you learn to work the motor hard, holding on to the lower gears and downshifting with purpose to stay in the power band, which is roughly the top 2000rpm.

Despite a crisp throttle response that allows blipped downshifts and heel-and-toeing, there are times when the engine seems to have a lethargic flywheel and the revs die out too easily. We were surprised by our 0-60mph time of 7.1sec, as the MX-5 never feels that brisk.

The smaller 125bhp 1.8-litre engine is also fine: smooth, noisy enough when required, mute otherwise. But its power-to-weight ratio of 109bhp per tonne isn’t much. Anyone hoping to get the best out of the MX-5 should opt for the stronger 158bhp variant and enjoy the extra 16lb ft of torque.

RIDE & HANDLING

There are few cars that trade outright performance for handling thrills, but the Mazda MX-5 is certainly one of them. For all the plaudits showered on the Toyota GT86 and its Subaru BRZ twin, it’s easy to overlook just how good the MX-5 is.

Standard variants (read non-Bilstein-equipped Sport Tech MX-5s) ride surprisingly well, but those models with the suspension rates wound up leave a car that never really settles on typical British asphalt.

The MX-5 breaks away at the back end more cleanly and responds better to corrections than it did before.

In either event, the MX-5 fundamentally offers deliciously balanced rear-wheel drive handling.

Once you are confident in the car, it can be driven up to and beyond its limits of grip more easily than just about any other sports car around. The Mazda telegraphs a slide early on but is easy to catch with some opposite lock and a sensitive right foot.

Earlier versions of the Mk3 were somewhat handicapped by a degree of glutinous resistance on the hydraulic steering system, but a revised set-up applied to the 2009 facelift helped to restore some of the lost fluency.

One development that could hardly be faulted was the fitment of traction control and stability control on the MX-5. Second-gear oversteer on a roundabout is one thing, but the rear will step out at the top of third gear pulling on to a wet motorway, and the short wheelbase can make that kind of behaviour tricky to handle at speed. Electronic intervention is a worthy safety addition.

Purists will bemoan the additional mass of the Roadster Coupé, which naturally sits high in the car and raises the centre of gravity, but you’d need back-to-back spirited drives in both to tell the difference. And even so, the hard-top is hardly lead-footed.

MPG & RUNNING COSTS

Mazda MX-5

Where pricing is concerned, the MX-5 sits largely in its own orbit and remains a car with few direct rivals.

A 2.0-litre BMW Z4 is considerably dearer but is a much plusher and more refined car than the back-to-basics approach adopted by the Mazda.

The 2.0-litre Mazda should return an acceptable 30mpg in day-to-day use

A Lotus Elise 1.6 is also considerably more money, and leans towards the more hardcore end of the market, where Caterham sits.

Alternatively, there are a whole host of cropped hatchbacks which come closer to the Mazda, but none can hold a candle to its dynamic finesse or sporting appeal. Even the £25,000 Toyota GT86 is substantially more expensive.

The 2.0i Sport seems a little pricey, although you do get air-con, a limited-slip differential, a six-speed gearbox, the bespoke Bilstein dampers and a cross-brace, heated seats, a Bose sound system and cruise control.

Thanks to Mazda’s famed build quality and reliability (don’t worry, this MX-5’s no exception), the MX-5 won’t cost the earth to run.

In the standard roadster, the 1.8-litre unit will return 39.8mpg and the 2.0-litre 36.2mpg. Automatic ‘Powershift’ models see fuel economy drop to 35.3mpg, while CO2 emissions stand at 167g/km for the 1.8, 181g/km for the 2.0 and 188g/km for the auto.

Insurance groups range between 21 for the entry-level 1.8 Roadster Coupé, and 26 for the soft-top 2.0 Sport model.

One thing that might trouble some, however, is the absence of a spare wheel – and no provision for the fitment of one. You're either going to have to come up with your own solution, or rely on your breakdown cover or the supplied tyre sealant system.

VERDICT

4 star Mazda MX-5

At one time, Mazda was accused of being a one-car company and the MX-5 was that one car.

Nowadays, the rest of the range has risen closer to its excellence, but the lithe roadster is characterful enough to remain the jewel in the manufacturer's crown.

Few cars retain a distinguishable link to their ancestor, but the MX-5 remains a happy slave to its 80s ethos

The new MX-5 is roomier, quieter, safer and better equipped than its predecessor.

Driven hard, it rewards the driver with thrills at licence-friendly speeds, and it will improve your skills more in a week than a hot hatch would in a year.

It’s not without its drawbacks though. The interior is feeling its age and its refinement is lacking by the standards of its admittedly more expensive rivals.

These days there are few cars that trade power and speed for entertainment, but the MX-5 is one of them.

It’s also a more practical proposition than the old Mazda MX-5, although you’ll still struggle to fit more than a single suitcase in the boot.

That’s not a reason not to buy one, and there are many reasons why you should.
