Default 2012 Mazda 3 Gets 158-HP Sky-G Engine, On Sale This Fall / Driven Diesel


http://blogs.insideline.com/straight...this-fall.html

Quote:
A refreshed 2012 Mazda 3 hatchback quietly debuted this past week in Toronto... well, maybe not quietly, but we Americans don't exactly have our finger on the pulse of current events in Canada. In any case, the car is subtly restyled, but still maniacally happy. The much, much bigger news is that the 3 will have Mazda's new direct-injected "Sky-G" 2.0-liter inline four-cylinder gasoline engine when it goes on sale this fall.

Said engine will make 158 horsepower at 6,000 rpm and 151 pound-feet of torque at 4,000 rpm while running on North American-grade 87 octane. That's with a 13:1 compression ratio. (On higher octane European fuel, the engine will run at 14:1 compression and make 163 hp and 155 lb-ft.)
This engine will initially be offered with the new Sky-activ six-speed automatic transmission that's lighter and more efficient than the current five-speed automatic. We'll see Mazda's new 6-speed manual transmission, too, but availability will be delayed in North America (where manual-gearbox take rates are low compared to Europe). Still, says Mazda spokesman Jeremy Barnes, "there is every intention that there's a manual coming though."

Engineering Editor Jay Kavanagh has already sampled both the Sky-G and the 2.2-liter Sky-D diesel engine (headed our way in early 2013) in Euro-spec Mazda 6 prototypes, so check out his driving impressions after the jump.


Driving Sky-G
At a briefing in Berlin, Germany, we drove various development mules (TPVs or Technology Proveout Vehicles in Mazda-speak) of the next-generation Mazda 6 equipped with the 2.0-liter Sky-G coupled to the new six-speed automatic and manual gearboxes. These were the higher-compression ratio versions, not the U.S.-spec ones.

Right away, the thing you notice is that this is not an engine that needs revs to deliver the goods. Torque is ample even at the low end of the tach, and it is delivered brightly all the way through the midrange and near the upper reaches.




In its current guise this is not intended to be a performance-car engine, but for everyday use it provides the right kind of motivation -- solid and linear thrust from low revs. The combination of direct injection and high compression provides sharp throttle response, too. It's the kind of engine that will serve Mazda's workaday applications quite well.

It could use a bit more personality like a more mellifluous intake note as today it sounds fairly prosaic. Final calibration and NVH work is still underway, though, so maybe there's a chance Mazda can fruitify the engine note. Yes, fruitify. -- Jay Kavanagh

Driving Sky-D
Mazda handed us keys to yet more Mazda 6 development mules, these ones sporting the Sky-D diesel engine. And believe us when we say that this 2.2-liter diesel is poised to make a splash when it shows up here in the U.S. in the brandy-new 2013 CX-5 cute-ute (basically a tall Mazda 3 hatchback).

Mazda benchmarked Europe's best diesels in the development of Sky-D and reckons they've got the establishment beat all around.
Torque is the calling card of a diesel, and the Sky-D delivers. In U.S.-spec guise it will churn out 310 lb-ft of torque at approximately 1,800 rpm and generate a peak of 167 horsepower at 4,500 rpm. It'll rev all the way to 5,200 rpm, which is pretty darned high for a diesel, permitting gearing that doesn't necessarily have to be super tall.

Sky-D said to return 43 mpg on the U.S. highway cycle in these cars. Mazda hasn't confirmed the existence of the CX-5, so take your best guess on its fuel economy.

Our driving route in Berlin included an unrestricted portion of the autobahn. Here, the Sky-D pulled with authority. Its powerband is broad and immediate and there was really no need to downshift to get back up to speed after a bit of light traffic materialized ahead. We could just leave it in 6th and give it wood. With little effort, we were cruising at just shy of 140 mph.

Around town the Sky-D similarly impressive. There's precious little waiting around for boost to arrive. Sure, you can force it below its boost threshold by laying into the throttle at 1,500 rpm in 4th, but even then the engine doesn't exactly go flat. In actual practice, a meaningful swell of thrust is always just a toe-dip away.

This engine doesn't feel like a boat anchor in the nose of the car since the block is aluminum. It's quite smooth, too, thanks to a counter-rotating balance shaft. You can, however, tell this is a diesel by the way it sounds. Not because it is clattery -- it isn't. Thrummy is a better description. In the diesel-averse United States, Mazda would do well to spend some more time on the Sky-D's aural signature. This diesel's got the kind of power delivery and response that will win over skeptics, so why not make it a trifecta of win? -- Jay Kavanagh

This is good news.. and will probably steal a ton of the market from VW.

I thought the point of the Sky-G was a significant bump in fuel economy. Not one single mention of it.

Many new possible practical + efficient vehicles for my wife come 2013 or so:

Mazda CX-5 Sky-D
Ford C-Max Energi
Toyota Prius v
VW Jetta SportWagen TDI
Volvo V60 diesel PHEV, should it ever come to fruition, assuming it isn't cramped in the back…

so pathetically weak, even for a daily.... toyota/yamaha was able to extract 180hp from the 1.8l 2zz motor... although using premium fuel, thats a LOT more performance per/liter than this boat.

Meanwhile, Honda sold 260k of them last year, second only to the Corolla in that segment which only sold 6k more. The third place Ford Focus sold nearly 100k less than Honda did Civics.

But uh yeah, you're right, not competing, sure.

Of course the 2ZZ was the performance model engine in the likes of the S-model Toyotas (Celica GT-S/Matrix XRS/Corolla XRS), so really the 140hp 1ZZ was the engine you should compare this to. And there is a premium-only performance motor for this car... it makes 260hp. So maybe you can stop making stupid comparisons now.

That 180hp was at stratospheric RPM (about 8000 as I recall), and below 6000 rpm the motor was completely gutless. It also had crap fuel economy. Not what you really want out of a daily driven family hatchback, especially in the days of $3+ gasoline. As the new Miata's motor, on the other hand...

it had great fuel economy...best of any car I've owned

if you want easy on it you could get 24-25 around town and 33+ on the highway. it did have a crap stock tune but it was still quite amusing. great interior too. my bro picked up a beat 03 vibe gt 6 speed for 2200 with 170k on it, just rolled past 200k and it still pulls hard in lift

The only thing that concerns me about this article is that it implies that we are only getting the diesel in the CX-5, and not in the 3 or 6.

Bring the diesel four! BMW has been hogging theirs all to themselves in Europe for quite a while. Didn't think I'd see a non-Euro automaker stepping in. Interesting that it's an Al block, should help handling quite a bit. Now Jetta TDI Cup will have some competition. Sorry all I can manage this time of am is disjointed phrases. And they said, "give it wood."

High compression ratio and nothing to show for it?
