New Mazda MX-5: 184hp, 7500rpm? Sold.

Japanese mags already have their hands on the MX-5 update, and the news is good...



With free reign to rework the current Mazda MX-5, what would you change? A difficult one, really, because it does such a good job of nailing its lightweight roadster brief. That said, a bit less body roll might be nice, as would more adjustment in the driving position, particularly for taller drivers. And nobody is going to turn down extra power, are they?

With the 'ND' fourth-gen car having been on sale for more than three years now, an MX-5 facelift isn't far off. For Japan that car is already a reality, the prototype drives now emerging on its automotive websites.  And despite the car looking remarkably similar, there appear to be some very worthwhile tweaks to the MX-5 under the skin.


Most notably, the Skyactiv-G engines have been overhauled for more power. In a world of desensitised and flat, downsized turbos, the zingy and eager atmospheric engines of the MX-5 are even more enjoyable than ever. For the facelifted 2.0-litre, power is up from 158hp to 184hp and torque increases from 147lb ft to 151lb ft. The 26hp jump has been achieved the old-fashioned way, too: if you want an engine to make more power, you make it spin faster, and as such the 2.0-litre now revs to 7,500rpm (up from 6,800rpm before). To handle the increased speed in reciprocating mass more comfortably, each piston and conrod is lighter (by 27g and 41g respectively) and the crank has been redesigned. In addition, the "passage area" of the throttle valve is 28 per cent larger, the port area is expanded by 18 per cent, and the exhaust valve diameter has grown as well.

Add to that a new flywheel - said to be of the 'low inertia dual mass' variety - plus a different exhaust silencer for improved noise, and it's clear that there's quite a lot more to this MX-5 update than meets the eye. The 1.5-litre car also receives the larger intake port and lighter pistons, though with more modest gains; and by more modest we mean one horsepower (to 132hp) and one pound foot (to 112lb ft). Still, something is better than nothing, right?


Alongside the engine modifications, perhaps the most interesting change for this MX-5 is the introduction of telescopic steering wheel adjustment. Sounds minor, but anybody who has been forced to stretch to the overly large wheel will appreciate just how irritating the rake-only adjustment that has persisted until now was. While the reach adjustment is only 30mm, the (translated) Japanese correspondent here says that the driving position is "low enough to be a sports car by the telescopic". Sounds positive...

Finally, it's probably worth noting the new 'Caramel Top' and 'Sports Tan' colours available for the hood and interior, softer rubber bushes in the rear suspension and improved active safety features. Certainly that's what we know of so far, although more could be coming - with added details surely set to follow over the next few months. And if the mid-life spruce up has you keen on an MX-5, don't forget that early cars are now out of warranty (or very close to). There's no excuse not to give BBR a call then...

Sounds a lot of effort, just stick a turbo on it, everyone can remap it and we'll have a fast little sports car, not simply a nippy one (don't say it!)

15% more power, 7.5k rev limit - fantastic!!

I'm really surprised Mazda has released such a power increase to the 5 as they have always been reluctant to change the lukewarm basic formula. Really looking forward to seeing this hit UK shores.

Sounds interesting, that's a considerable power upgrade (for Mazda). It will be interesting to see reviews on it. I've been thinking about replacing my NC 2.0 Sport for a brand new ND (some dealers were offering really good deals back in March/April) for some time now and this update may just give me the final nudge I need.

Considering how surprisingly rapid the current model is (6.3 to 60 and 15 over 1/4 mile in the RF) this should be a good wedge quicker.


Can't wait to scan the classifieds in 20 years time to catch me a bargain!!

Sounds a lot of effort to go to Mazda, just be lazy and install 5kg worth of turbocharger and 5 kg of intercooler which goes against the car's ethos, creating yet another dumbed-down car (don't say it!)

I love that Mazda are not giving up on the petrol engine. In fact, they're doing quite the opposite and i'm personally glad about it. I personally think that there's life left in the old girl yet!

More power to match the looks it's also a tasty addition. It may even make the little sports car appeal to a bit of a wider audience. I've always said that it could do with having a little bit more grunt.

I read about this forthcoming update a few months ago and I reckon its just the boost the car needs. Unlike many on here, I don't particular yearn for a turbo, but a nice n/a engine with 184 BHP will be about perfect in a little car weighing just over a ton. If my maths is right, the new power to weight ratio will be similar to a Mini Cooper S JCW, or Peugeot 208GTI Peugeot Sport edition, so hitting that sweet spot they often talk about on Pistonheads of around 170-175 BHP/ton......

I'm pining for my recently sold MX-5, so can see myself getting one of these in a few years time...

It will be a sad day when (if) Mazda put a turbo on it.

There is everything to like about this new update lick

Where did those figures come from? Mazda themselves say 7.4 to 62

This will be on my list in a couple of years. The Elise is too special for an everyday-type sports car. This ticks every box.

This is really interesting news, good on Mazda for not just bolting a turbo on.

Should be a hoot drive. I’ve got a 190bhp in my NC and it’s a good giggle to thrash around: https://youtu.be/Fc3jVCBVMFg

Oh and another thing...

They wont get rid of the body roll that Pistonheads, EVO and others are always moaning about. Its that relative softness that helps make the MX-5 friendly in the wet. Make it too stiff and people will be spinning off left right and centre. One thing I always loved about my NB was that I could hoon it about in the wet and not fear it was going to bite.

After 28 years and over a million plus sales, if it ain't broke......

Motorweek. Check out the review of the RF on youtube. I think Motor Trend and a few others may have extracted even better figures during their tests.

The telescopic wheel makes me more interested than the power hike, to an extent, I gave up trying to fit in one at the MK3 as the steering wheel was just too close to the pedals.

Looks brilliant, already a great car but with just the tweaks it maybe needed. It's still one of only three new cars I have any interest in, I'd really like one of these.
