Mazda has unveiled a new engine at the Automotive Engineering Exposition which took place at the Pacifico Yokohama convention center near Tokyo inJapan.
 
The new direct-injection 1.3 liter SKYACTIV-G unit comes with 84 PS/62 kW and 112 Nm of torque and features a remarkable consumption rating of just 3.3 liters/100 km (71.2 mpg US / 85.6 mpg UK). The gasoline power plant is naturally aspirated and achieves a remarkable compression ratio of 14.0:1.
 
SKYACTIV technology on the new power plant includes special piston cavities for more optimized combustion process and multi-hole injectors for more precise fuel mixture.
 
The new power plant will debut in the facelifted JDM Mazda Demio model in Japan this summer - sold as the Mazda2 around the world.
 
Mazda's SKYACTIV technology is a group of next-generation features for improved fuel-economy and performance that extend beyond engine tech and into transmission, body and chassis designs.

Never mind hybrids.

What does that convert to in hp and foot pounds/pound feet of torque, anyone?

[Spunnel]

83hp & 82ft/lbs

So if you double the engine size to 2.6 liters and the output then is similar to what we have now in the 3; you'd halve the mileage to 30 - 35 in a larger vehicle which is what we're getting now.  Isn't that more or less correct?

I think a separate article mentioned that the 2.0L skyactiv engine for the Mazda3 is expected to achieve 40 mpg on the highway (US gallons btw) - 155hp and 148 ftlb torque

It's always interesting to see what that pans out to in real life driving.  As I've posted elsewhere. the best mileage I've gotten with my hatch, and driving conscientiously to get good mileage, was just under 42 mpg highway which I believe works out to 35 mpg (US gal)

I'm driving Jasper to Canmore return on this Sunday and we'll see if the lighter wheels make any difference in mileage.  With my '96 Camaro 3.8L, 200hp V6, I get 30 mpg(Cn) driving in my normal fashion on the highway at 115/117 km/h. with some city driving thrown in.  Both cars are kept in good running condition.
