All-new Mazda MX-5 teased

Well the chassis is at least, along with 25th Anniversary edition of current car



The MX-5 may well be a Japanese evocation of classic European sports cars but the heart and soul of it was conceived in America and the car made its debut Stateside 25 years ago. That was Chicago but Mazda has waited for the New York show to unveil its 25th Anniversary Edition MX-5 and it's ... red.

Given its world record status (940,000 cars and counting) and place in the hearts of many you might have hoped this fairly significant milestone would have been marked with something a little more involved. Something, perhaps, like the super lightweight Speedster created to mark the 20th anniversary. Sadly not, the 25th Anniversary Edition being little more than the usual run-out template of one-off paint scheme, some gunmetal alloys and 'off white' leather to finish off a spruced up interior.

Well it is a nice shade of red at least
Well it is a nice shade of red at least
So much for that then.

Given the MX-5 team is heads down working on an all-new fourth generation car maybe they simply didn't have the time for anything more involved. And New York is also the first real hint of what to expect, the new car's chassis on show for the first time. And, thankfully, showing Mazda is sticking with what it knows for the fundamentals.

So we've got a twin-cam four-cylinder engine behind the front axle, a manual gearbox, a torque-tube style beam linking it to the rear differential and double wishbone suspension all round. Exactly like all MX-5s that have gone before. This is a good thing.There's more encouraging news too. Mazda is claiming an overall weight saving of 100kg compared with the existing car and the engine is mounted lower and further back than before for improved centre of gravity. Given the existing hardtopped Roadster Coupe weighs in at an already svelte 1,230kg including driver that bodes very well indeed.

We'd hope for more than a pimped interior...

It gets better too, Mazda confirming the new MX-5 will be based around its Skyactiv engine principle which rejects downsizing and turbos and instead uses unusually high compression ratios and other innovations to keep the flag flying for revvy normally aspirated engines. It's the first time a Skyactiv engine has been used in a rear-drive format but if we were to take a punt on it being a version of the 175hp 2.0-litre from the Mazda 3 we'd be happy with that.

"The original concept behind the MX-5 was so simple; to offer the pure joy of a lightweight sports car that moves precisely as the driver intends," says Mazda's head board member Takashi Yamanouchi. " While responding to increasing safety and environmental requirements, over the 25 years since its launch we have had to continually reinvent the MX-5 - far beyond simple evolution - in order to stay true to that original ideal. The history of the MX-5 is one of changing everything in order to stay the same. A history of innovating in order to preserve the ideal."

And if that means we can have all we like about the MX-5, just lighter, more efficient and better balanced than before then it sounds like there's little to fear and much to look forward to with the new car.

So that's the chassis is it? Where can I get a job as a motoring journalist....?

100kg weight saving is very impressive. 175bhp would be nice too - would make for some pretty decent performance stats. Here's hoping they manage to keep the price affordable.

I applaud Mazda's commitment to N/A engines and weight reduction.

Agree 100% here! sub-1200kg is pretty decent with an electric folding roof etc, and 175hp should do very nicely.

Knock off the standard 75kg for driver and the new car will actually be ~1050kg (or less) wet, which is quite impressive.

Now please, please stick with hydraulic power steering.

If this really does weigh 1100kg or less, has a 175bhp+ NA petrol engine and hopefully a manually operated fabric folding top option then it could be rather good. I've not seen any guidance on pricing yet though, <£20k would be great but I very much doubt it will be.

I'd be very surprised if it has hydraulic power steering, as every other Skyactiv model uses EPAS.

I'd guess ~£25k list for the 175bhp version. I guess they'll probably do a cheaper lower powered one too, though. An entry point of 160ish bhp/tonne would be excessive for this sort of car.

Are they still colab-ing with Alfa?

If so this sounds good for the new Spider.

Okay, clever-clogs, what would you call it then? I agree its not all of the chassis as there is a (presumable) monocoque as well... but I'm not sure what else you'd call it?

Is there, or is it an AC compressor? I'm also not sure whether the thing on the far side of the engine is another pump or simply a tensioner.

That would be my guess too. I think that 160bhp/ton sounds spot on myself but probably unnecessary for a large proportion of those who will actually buy one. I await further details with interest anyway.

This is a SkyActiv petrol engine from the CX-5/Mazda6, both run EPAS so no PAS pump - The picture shows the same belt configuration in both images

Every other Skyactiv model is also FWD, but the MX-5 is a special case, so I'm optimistic Mazda will see fit to continue with hydraulic PAS. The numbness on initial turn-in was quite noticeable on the GT86, so I'd think that, of all the things that make the MX-5 what it is, steering response would be high up the list and therefore worth making sacrifices to preserve.

I believe the NC ran a trailing-link rear suspension? If so, then a return to rear wishbones is welcome, not that the RX-8 handled so badly.

As for EPAS, the RX-8 had brilliantly feelsome steering with EPAS, so I'm not that worried. There does appear to be an unsightly motor-shaped bulge to the front of the steering rack. That said, I've not driven an NC (same steering system as the RX-8?) and that apparently lacked feel...

Still, I'm in the camp that says a car weighing only 1050kg doesn't really need PAS.

ppf or power plant frame that what mazda calls it.

Sounds promising for the mk4 170 bhp and around 1100kg good figures to me.

My mk1 is 900kg and 115bhp which is plenty powerful for a small 2 seat roadster this should be good.

The current MX-5 is hydraulic PAS.
