When Mazda introduced that the 2019 Mazda MX-5 Miata was getting a critical improve in energy, I used to be each excited, and nervous. I used to be excited as a result of extra energy is all the time thrilling, and it was no insubstantial improve. At 181 horsepower, it is probably the most highly effective manufacturing Miata ever provided, beating out turbocharged Mazdaspeed Miata’s 178 horsepower. Plus it has extra revs to play with.
However what had me apprehensive was whether or not this energy would mess up the pleasant, playful character of the Miata. The one hundred fifty five-horsepower 2.zero-liter engine is nearly good, virtually universally liked by the Autoblog employees and different reviewers, with good mid-range torque and brief gearing that all the time made it really feel fast in almost each rev range. It felt like the correct quantity of energy for the chassis, too. There was simply sufficient to get it unfastened with out working too exhausting, nevertheless it would not spin you round unexpectedly.
I might think about a pair methods the brand new engine might have an effect on that candy stability, too. One can be that it will be only a bit an excessive amount of energy, and lose a few of its accessibility and predictability. Principally, it’d develop into extra critical and never as enjoyable-loving. I additionally feared that in pursuit of a better redline and extra horsepower, the low-finish of the rev range may turn into painfully sluggish. Honda house owners know this sense each time their VTEC-outfitted screamers drop out of the aggressive cam profile, and the Toyota 270 and BRZ endure from an terrible lack of torque proper within the mid-range that does not recuperate till almost redline.
All of this was on my thoughts when the assembled reviewers have been briefed by Mazda engineers concerning the car. It began out like most shows, with a quick rundown of the objectives of the car and what Mazda has achieved with the mannequin to date. Then got here a chart displaying the facility curves of the NC, present ND, and the 2019 mannequin, and my worry of a lack of low-finish grunt dissipated. The quantity of energy and torque over engine velocity is almost similar between the previous and new ND Miatas proper as much as round four,500 rpm. After which from there, the 2019 continues making extra energy all the best way to its 181-horse peak at 7,000 rpm, 500 rpm greater than the earlier mannequin’s redline. This was an excellent signal.
Mazda managed to get these positive factors with no sacrifices by way of many small upgrades. The throttle physique is wider with a slimmer throttle plate, the consumption manifold has longer runners and twin paths, and the consumption ports are bigger. The exhaust valves, ports and header pipes are greater, and the exhaust cam has a bit extra period and raise. The pistons have been redesigned with slimmer skirts for much less friction, new tops for higher cooling. The rods have stronger, shorter finish bolts for much less weight, and the crank is stiffer. Lastly, the fuel injectors run larger strain for higher fuel atomization.
Mazda additionally sought higher refinement, including a twin-mass flywheel to assist with transmission noise and vibration, adjusted the digital throttle to flutter a bit to remove vibration from the engine rocking underneath energy, and tweaked the muffler for a smoother sound.
All of the powerpoint slides and engineering speak is ok, however the true test is definitely driving the car. Over the course of two days, I drove freeways and mountain roads between San Diego and Pismo Seashore racking up tons of of miles between a Miata RF Membership and smooth-prime Miata Grand Touring. And what I discovered is that I actually should not have fearful – and heck, with Mazda’s almost 30 yr monitor document of enjoyable Miatas, I actually, actually should not have fearful. The 2019 Miata is principally the present one, however with an additional little layer of icing. And that icing is scrumptious – virtually too scrumptious.
Let’s begin with the engine, which manages to really feel identical to a present Miata when hustling it round city. It is obtained sufficient grunt to really feel peppy on the town, and it is not so quick that you’re going to be cursing each velocity restrict signal you move. When floor streets give option to a freeway on-ramp is if you’ll first discover the additional energy and revs – and you will discover the revs greater than the facility, because the car is ready to maintain every gear just a little longer to savor little engine’s livid growl for a couple of moments extra. The facility, although, is far more delicate. It isn’t just like the hit from a turbocharger and even the cam profile change in some VTEC engine. It principally continues the present Miata’s clean energy previous the previous rev restrict of 6,500 to the brand new considered one of 7,200. It feels identical to the previous car, nevertheless it simply retains pulling for longer. Then on backroads, the muted bass of the consumption and the upper snarl of the exhaust mix with the facility to encourage you to maintain the engine as near redline as potential. And it is easy to take action between the car’s laser-exact, slick-as-a-mild-change shifter and the engine’s willingness to construct revs.
Additionally evident when driving round are the modifications Mazda made to make all of it extra refined, and it comes by means of within the sound. There’s loads of the previous growl, however the entire engine sounds a lot smoother. It is misplaced any raspy-ness and off-pitch notes the previous one had. Whether or not that is an excellent factor is debatable. I personally appreciated that the present Miata was a bit uncouth. It was prefer it was sporting a barely wrinkled T-shirt, and the brand new one is sporting a nicely-ironed collared shirt. Neither is basically dangerous, simply totally different.
What hasn’t actually modified with the Miata is, properly, principally every part else. Chassis-sensible, it feels as nimble and stiff as ever. It is mild weight lets it shortly change instructions with out drama, and the considerably delicate suspension results in some physique lean, however it additionally means it could deal with uneven again roads with out being upset and bumped unfastened. The chassis is consistently letting you understand which finish of the car is getting just a little unfastened, and nothing occurs overly shortly, so you’ve got loads of time to right with throttle and steering inputs. The steering is delicate and lightweight, which inserts the character of the car completely, however its suggestions and precision falls a bit in need of the 270 and BRZ.
Associated to all this are some fascinating variations and lack of variations between the 2 automobiles I drove, an RF Membership with the BBS and Brembo package deal, and a gentle prime Grand Touring. The Membership is certainly a bit extra stiff, however not enormously so, nonetheless exhibiting lean on corners. I can also’t advocate the BBS and Brembo package deal. The wheels definitely are sharp, however the Brembo brakes did not really feel notably stronger than the standard models. Save your cash and purchase some upgraded pads and the wheels of your selection. Usually, the brakes on each automobiles might be a bit firmer, too. Additionally noticeable between the 2 automobiles was the RF’s additional weight. For reference, the RF is a bit over one hundred kilos heavier than the two,339-pound guide gentle prime. Going round corners, you might really feel the entire car pushing farther vast than the delicate prime.
The commerce-off to the Miata’s charming engine and dealing with is that it isn’t splendid for lengthy freeway jaunts or particularly bumpy metropolis streets. First off, it isn’t quiet. Wind, street and tire noise is omnipresent, no matter whether or not you are within the RF or a tender prime mannequin. The distinction is between low roar and medium roar. Additionally, whereas the Miata has comparatively tender suspension, it is nonetheless small, mild, and does not have that a lot suspension journey, so you will nonetheless be bounding up and down a good bit over greater bumps.
Inside, nothing has modified both besides the inclusion of a telescoping steering wheel. As Mazda representatives defined, it was its personal main engineering venture to maintain weight down; the brand new unit solely weighs one other half pound. It is positive to make getting snug simpler for most individuals, although one other inch outward would have been good for my preferences. Nonetheless, the driving place is sort of snug and low. The Recaros are the identical, which is certain to please Affiliate Editor Reese Counts. Whereas they do supply good help, these of bigger construct, resembling myself, might choose the much less bolstered inventory seats. The interior additionally nonetheless engaging, and the controls are a breeze to make use of. The plastics are low cost and arduous, nevertheless it’s not one thing you will be too nervous about. The cup holders are nonetheless subpar, and the passenger aspect continues to be tight.
There are a handful of different small modifications to the Miata. Probably the most notable is the GT-S, which lastly lets consumers have all of the consolation features of the GT together with the Membership trim’s stiffer suspension and restricted-slip differential. Pricing has additionally gone up a couple of hundred dollars for the RF fashions, and pricing for the tender prime is coming quickly.
The essential factor to remove from all of that is that, even with the additional energy and tweaks for refinement, Mazda hasn’t ruined the Miata method within the least. It is the identical mild, playful little car that is stolen our hearts for years, however simply made somewhat sweeter.
