The next-gen MX-5 Miata thread

[eSZee]

Remember highway ratings are set at 65 mph. Most people don't remember that and expect the same numbers while doing 75-80. I know my GTi loses 3-4mpg between 65-75 mph.

You sure they're not set at 55?

You sure they're not set at 55?

Looks like according to this:

It's 60mph, so even worse than I thought. And it's with A/C off as well.

Edit: Flyin Miata put their ND on the weight scales:

Our ND hit the scales over the weekend. This is with a full tank of gas, and the car's in full GT spec. We can't complain about this one bit.

Dayumn... That's with fluids and gas in it? About 1,060 kilograms... impressive. As is the almost perfect weight balance... though the driver will throw that off by a few percent.

-

Economy testing used to be done AC off completely, but there are parts of the cycle done with the AC on, also.

You'll also note how vertical the test is... how many times the car has to come to a complete stop. This is why EPA numbers are so easy to beat. Anticipate lights, cruise as often as possible, drive a bit slower, and bam, you're over EPA.

Premium, same as NC.

If the timing variance is really that huge that it can run a miller cycle, why can't it run on regular?

I know, I've seen that video. You could have just said "because of throttle response". But why not run regular and be ultra sensitive on the throttle? I drove a Hyundai with a cable hooked up to the throttle and a popsicle stick pedal. I drive so gently that my Lexus can't figure out which gear to use.

That's 6 bucks more per tank. Who can afford that? I'd rather buy a beer.

Be cause the engineer could explain it better than I ever could.

And premium price will depend on where you live. Here it's only $.20 more than regular, so probably around $2-3 extra per tank in this car. My GTi runs on premium and I'm not complaining.

 

[Grandea GTR]

I dunno. If the other Mazdas use a rather high compression ratio that make would make them use premium, but has the tech to make them use regular gas on their engines, why can't the MX-5?

"Throttle response"

Come on dude. Also, I drove by the gas station that I fill up at this morning on the way to work and the difference between regular and premium was actually $.12.

In other news, Flyin Miata has put a more compact brake setup on their ND and switched to 15" wheels resulting in a net weight loss of 18.6 lbs.

 

[Heldenzeit]

15s look really goofy on that haha. Needs some low.

 

[Grandea GTR]

"Throttle response"

Come on dude.

Misquote or what? On another note, I'm not really complaining about premium gasoline and it's price, but I am overall curious as to why this Skyactiv engine requires premium.

I already know the feeling of using only premium, driving the FD RX-7 and whatnot

Nobody should be asking why, Dave Coleman explains it perfectly in the video. There he has your answer.

 

[homeforsummer]

Agreed. Looks really under-wheeled. The standard 16" on the 1.5s over here (not sure if that wheel size is offered over there) looks pretty much perfect for me. I can understand the weight benefits, but the ND isn't a shape that'll really suit smaller wheels, I suspect.

 

[Cano]

Even lower, the wheels will look terrible on it.

 

[Heldenzeit]

Here is some low. Non working pics is a real issue....

Rendering, but same wheels as the FM car.

[CodeRedR51]

Yeah if you go 15's you need some beefy tire.

 

[Heldenzeit]

I think 949 Racing is going to test 17s on it. The RPF1s on the red car I posted are 16x8s.

 

[CodeRedR51]

I'll stick with 16's on mine and go for the beefy tire look.

 

[05XR8]

Super Miata concept. Has the right tyre proportions.

 

[CodeRedR51]

If those are 15's, that may entice me. But would have to see it in person to make a final decision.

 

[Grandea GTR]

I think 16s fit it much better. Some 15s may do.

 

[Heldenzeit]

Here's the updated 17" version.

Looks better. 👍

 

[05XR8]

The MX-5 is small for 17s. it does need wider tyres though. I prefer the smaller wheels in the first Super M pic, with raised white letters even. The stock 16s are staying on mine. I'll lower it just a fraction. Some nice lightweight wheels for track use will come in handy.

 

[05XR8]

I got a quick training on MX-5 features(for Australian models) no brochures available yet:

All models come with an LSD, power windows, A/C

Only 1.5L available( initially) until November and then 2.0L joins the range.

1.5: bright 16" wheels, cloth seats, standard radio. Optional black boot lip spoiler.

1.5 GT adds: dark 16" wheels, LED DRLs in front bumper bar, SATNAV screen, MDS control in center console, leather seats

2.0L base features same as 1.5 base, adds: SATNAV

2.0L GT: comes with leather, body kit and black 17" wheels

Interesting how the boot lid release outside the car, is recessed next to the number plate lights.

A turbocharged version of the new fourth-generation ND Mazda MX-5 has not been ruled out… And nor has a fast and focussed MPS MX-5.

That’s the word from the program manager of the ND, Nobuhiro Yamamoto, the same man who told motoring.com.au at the Goodwood Festival of Speed last month that he invited anyone wanting more performance than the new MX-5 offers to “drive another car”.

But at this week’s Australian media launch of the 1.5-litre version of the ND, Yamamoto backed away from being that definitive when reminded of comments given by Mazda global PR boss Kudo Hidetoshi to motoring.com.au at an MX-5 preview event in Spain in February.Back then, speaking in the context of the ND’s expected 10-year lifespan, Hidetoshi said: “A turbocharged or MPS variant is one of the options we will definitely consider.”

Yamamoto said his Goodwood comments were made in reference to the launch phase of the new MX-5, which goes on sale in Australia from this month. Watch out for our first drive review and the pricing and equipment rundown this Friday.“It’s not a conflict [between statements by me and Hidetoshi],” Yamamoto told motoring.com.au via interpreter.“Since the lifespan was mentioned at 10 years it is kind of long years, so thinking what Kudo-san said was just a possibility of having such a variant given the long lifespan.“It depends on how broad the scope is, what kind of timespan we are talking about. Depending on that I think there are many things you could think of.“Kudo san talked about this in terms of a 10-year lifespan, but when I was asked the question right after the launching of the ND, I said ‘we have no plan to have a turbo at that point in time’. That is what I meant.”

Asked whether he felt a higher performance version of MX-5, such as an MPS, could be developed without turbocharging, Yamamoto stated: “If you could achieve what we want, to which is great response, very light and powerful with great performance feel with natural aspiration, then we don’t need a turbo.“But if we want more power because we don’t get satisfied with natural aspiration then we may think about the turbo.”

Two versions of the lightweight two-door soft-top, rear-wheel drive roadster will be sold in Australia; the 1.5-litre four-cylinder which outputs 96kW and 150Nm is launched first, while the 118kW/200Nm 2.0-litre comes in November.

There have been a couple of turbocharged MX-5s launched through its 26-year history. One limited-edition, the 2002-03 150kW SP based on the NB, was engineered and converted in Australia with factory approval for local sale. Another, the 121kW SE, came out of Japan in 2004-05 at the end of the NB generation’s model life.

It would be logical for a future MX-5 turbo/MPS to use the 2.5 litre four-cylinder SKYACTIV engine that will first appear in the new-generation CX-9 SUV and the reborn MPS 3. A production version of the CX-9 will debut in Los Angeles in November, while a 3 MPS concept is expected in Frankfurtbefore that next month.

Despite admitting turbocharging was still a potential option for the MX-5, Yamamoto made it clear his preference was for the car to remain naturally aspirated.“Once you put a turbo the car gets heavier, you have to add an intercooler and the reliability of the engine [becomes a potential issue as well]. If you think about all those elements you may think a turbo is not a good idea.”That said, how much influence Yamamoto will have over a decision on an MX-5 turbo is bound to be limited. The launch of ND signals the retirement of the long-serving project chief.

Yeah, they had to point out that one to me the first time I drove it too. Neat solution for hiding the boot release, not so neat if you live somewhere like the UK, since that area will quickly become covered in grime, which will end up on your fingers any time you go to open the boot.

 

[05XR8]

Exactly what I thought.

Trying my hardest to get my credit straightened out and save a nice down payment for what I thought was going to be a Sport model purchase but might end up being a club without the Brembo package. January-February time frame.
