More powerful Green political movement.
Punitive taxes on engine sizes that exceed 1.6L.
Other than that . . . .

I took a dyno chart from a 155hp/150tq 2.0L SkyActive engine, converted it to Excel, and then manual played with the torque curve to shift it 600rpm higher in the rev range. I did this because a higher redline really suggests that Mazda would use more appropriately tuned intake and exhaust dimensions to support that extra RPM, and possibly cam differences.
It produces a pretty compelling number at ~154whp, which is about 170hp at the crank with the Mazda3's drivetrain losses. The ND's losses will be higher due to RWD vs FWD, driveshaft and all, but it should still make at least the 167hp mark of the NC if the 600rpm northward torque shift is anywhere close to accurate. If I underestimate the torque curve shift, it could easily climb up another 5-10hp.

Someone on mnet is claiming to have been in a focus group session:
The 155hp, 30.5k sticker, and the fact that it was posted at 1:30am Pacific makes me thing that someone just got drunk and was ******* around, but who knows?
I just came back from automotive survey featuring 2 ND miatas, one with soft top right hand drive like the one we saw in Monterey. One with targa/power retractable hardtop concept. They are being comparing against Audi TT, BMW Z4, Toyota FRS and Mini copper convertible.
The final number for miata is 155hp with 148ft/lbs and 2300lbs for soft top and 2400lbs for retractable hardtop concept. Retractable hard top / targa has panorama roof like the SLK.
The interior of the new ND feel smaller than my current NC. The door is higher or the seat is lower than current NC. Six speed manual is standard with keyless start stop. Navigation is on the Japanese model but doesn't know if American model have the navigation option. The navigation display is the Same as the new Mazda 3.
Soft top starting price in 30,495 and retractable hardtop/targa is 32,985

If the above is to be believed
ND ~ 155hp/148ft-lbs ~ 2300lbs ~ $30,000
And they are comparing it to...
Cooper S Convertible ~ 181hp/177ft-lbs ~2800lbs ~ $28,700
BMW Z4 sDrive28i ~240hp/260ft-lbs ~3300lbs~ $48,950
Scion FRS ~ 200hp/151ft-lbs ~ 2758lbs ~ $25,470
Audi TT ~ 211hp/258ft-lbs ~ 3340lbs ~ $43,350
(These are "starting at" MSRP prices and specs from the manufacturers websites for current models, so I assume 2015 at this point in the year)
I did some meaningless quickie back of the napkin calculations...
Dollars per HP:
ND - $193.5/hp
CS - $158.6/hp
Z4 - $203.9/hp
FRS - $127.3/hp
TT - $205.4/hp
Power to weight (hp/lbs):
ND - 0.067
CS - 0.065
Z4 - 0.073
FRS - 0.073
TT - 0.063
Then Mazda has a LOT of work to do

Not an apples to apples comparison between these sports cars and and a heavy american sports coupe, but even still, for $32k you can have a 435 hp V8.
$30k is not a Miata price. **** is nuts.

Unfortunately Australia has traditionally preferred larger torquey engines but we're slowly moving towards smaller engine cars due to the fact that petrol is about 3-4x more expensive than in the US. Weirdly though, 4WDs are becoming extremely popular family cars?

In the land of "There's no substitute for cubic inches!" I doubt that will ever happen.

I suppose the shaky auto industry in Detroit would really be hurt as well (big cubes and all), even if most of it is now owned by the Italians...

Crap indeed. I'd like to discuss an exciting bridge-buying opportunity with you.

Like it or not....agree with it or not...government regulations have a direct correlation to what we end up driving. It's not that I advocate bringing back unrestricted two stroke engines for cars, but this stupid government crap does have a bearing on what type of engine will end up in the ND.
By the negative props being given out, apparently some people don't want to even admit this. And they certainly don't want opposing viewpoints.
