Mazda just announced some pretty exciting updates on the 2019 MX-5 coming—thanks to consumer demand. Here's what they had to say:

IRVINE, Calif. (June 20, 2018) – The Mazda MX-5 Miata has never been about power; it’s a car whose sole purpose is to help the driver and passenger fall in love with driving. But, a little extra power never hurts, which comes as one aspect of numerous updates for the 2019 model year.

Mazda’s engineers enriched MX-5’s SKYACTIV-G 2.0-liter engine with the goals of improved response, performance, feel and efficiency. The net results are 181 horsepower at 7,000 rpm—a 17-percent improvement—and 151 lb-ft of torque at 4,000 rpm, with a richer torque curve throughout MX-5’s entire rev range.

Speaking of rev range, redline has increased from 6,800 rpm to 7,500 rpm. Engineers were able to increase performance through several means, including:

• Reducing internal mass and friction: Each piston has been reduced 27g in mass, thanks to a minimized skirt area. Connecting rods are 41g lighter than previous units.
• Reducing exhaust loss: The upgraded engine carries an increased valve opening angle and valve lift height. The inner diameter of the exhaust manifold has also been increased. The net results are a 30-percent reduction in pumping losses.
• Improved combustion: Reconfigured intake ports and new high-diffusion, higher-pressure fuel injectors improve the tumble and swirl of fuel in the cylinder and better-atomize fuel. The benefit is improved efficiency and torque at all rpm.
• Dual-mass flywheel: Replacing the single-mass flywheel with a low-inertia, dual-mass flywheel improves smoothness and responsiveness.
• A new exhaust system with richer sound quality.
• New final drive ratio: The transmission’s final drive ratio has been increased from 3.454 to 3.583 in order to improve linear response to match the driver’s intentions. Gear ratios are otherwise unchanged from previous models.

As a result of numerous changes, MX-5 is quicker, more responsive and aims to be more engaging to drive, adhering to Mazda’s unique Jinba Ittai—“horse and rider as one”—engineering philosophy.

Beyond engine improvements, the 2019 MX-5 introduces an available brown canvas soft top, new black metallic 17-inch wheels, a newly telescoping steering wheel (42mm of travel), easier-to-open doors and revised door stops and revised cupholders and seat levers.

On the safety front, the new MX-5 will be sold with a new, standard rearview camera and newly available features such as Traffic Sign Recognition and Smart City Brake Support in addition to other i-ACTIVSENSE safety technologies found throughout various trim levels. In the process of gaining many new features, the 2019 MX-5 gains just 7 lbs. from previous models, owing to a strict adherence to Mazda’s “Gram Strategy” and ingenious solutions like adopting an aluminum steering shaft in place of the previous steel unit.

When the fourth-generation MX-5 launched, its development team rallied around the idea of innovating in order to preserve. The latest round of innovations aim to continue that mission.

The 2019 Mazda MX-5 will be available in the U.S. this fall, with pricing, packaging and full specifications to be announced closer to on-sale timing. Details concerning the 2019-spec Global MX-5 Cup racecar will also be announced at a later date.

Mazda North American Operations is headquartered in Irvine, California, and oversees the sales, marketing, parts and customer service support of Mazda vehicles in the United States and Mexico through nearly 700 dealers. Operations in Mexico are managed by Mazda Motor de Mexico in Mexico City.

Nice to see the improvement are for all MX-5, was worried the hp boost was only with some $5,000 performance package option or something.

Awesome. Sounds like Mazda was listening and addressed most of the concerns (albeit small) owners had with their cars. Looking forward to test driving one this fall.

Eternal Blue was introduced for 2018 but very few were made and not many are aware of it. I expect it’s going to stick around.

That new blue + the updates is going to make it very difficult for me to not trade in the 135i over the winter....assuming they will give me a decent trade-in for it.

I see that, it would be fun to have a new smurf blue, or yellow, or BRG, or the NC winning blue though. 

Still cool updates for 2019 though! Hopefully it'll push the '16-'18 cars down in price.

Not much of anything to dislike about those changes. Wonder what it will do to the MSRP?

I still can't find any pics of Eternal Blue that make it 'pop' with a brightness or boldness even half as much as Kieth's image in the 'other' thread about this did.. Most look closer to the decidedly 'ho-hum' silver-blue that you see on the Mazda configurator and on some other Mazda's in the wild.  So I definitely wouldn't order that one sight unseen, expecting something interesting or exciting.

.

That aside: Building an engine with more mpg, more rpm, more hp, and more torque everywhere is quite the accomplishment!

I love that Mazda has a "Gram strategy." 

I wonder if this new mill will make it to the 3. That'd be cool.

That's why Mazda waited to announce, they wanted to keep the value of the cars on their dealer lots up as long as possible.

I have it from a Mazda insider that the ND does not wear green well. We may not see a BRG. Here's a cellphone shot of Eternal Blue sent to me.

• A new exhaust system with richer sound quality.

 

Was the '16-'18 exhaust that bad? Or was it just uninspiring?

In my opinion, a car like the MX5 needs a snorty exhaust.

I could see that with BRG. But on my way home yesterday, I saw a Mazda2 in that ridiculous (ly awesome) bright green. I don't know why, but it made me want to see how an ND would look in that color. I also have a feeling that the ND would wear yellow and orange quite well.

And that cell phone pic is closer to the others I've found for that color.  Sure it's 'nice', but it's still not what I would call visually stimulating either.

Plan on seeing failing DMF in the future! I know the cars that I have owned with them they dont seem to last long before making noise.

Just did the clutch in my 911 with 120k miles and reused the DMF.  No noise.  My previous 330i had 160k on the DMF.  It did make a little noise if you lugged the engine, but still worked fine.  100k on a MINI with a DMF and it was fine too.  

What are you driving that is failing early?

I'm sure if it's problematic, the aftermarket will be happy to supply single mass flywheels.

Yeah. Many different manufacturers have been using them on multiple lines for years.

Interesting that they did change the exhaust header as well. That might back up the some people suggesting that it was/is a bottleneck on the ND1.

Makes me wonder if the new exhaust including header can be retrofitted.

Oooo.....that blue is lovely!    Still can't warm up to the RF stying though.   I'll take mine in a true droptop!   

Although the updates are welcome, there isn't really much wrong with the ND as it sits.  I'm looking forward to the depreciation dip for the 17-18 cars.

I suspect the change wasn't because it was an issue on the ND1 (not saying it is), but because it wasn't going to work at the power levels and RPM ranges the updated engine produced.

There's more to the changes than just throwing parts at the engine and looking at the peak numbers generated.

The DMF on the MINI is actually a fairly known problem.  My 2006 rattles. Most of my friends with MINI's have had similar issues.  Eventually I'll replace it, although probably with another DMF since the aftermarket versions are generally worse.  Just the nature of the beast.  For now I just keep the clutch pedal in and ignore it.
