Opel’s new Corsa three-door equipped with 70 kW/95 hp 1.3 CDTI ecoFlex diesel with Start/Stop technology fitted as standard, braking energy recuperation and low-rolling-resistance tires combined with the new Easytronic 3.0 transmission can reduce CO2 emissions to 82 grams per kilometer.
Fuel consumption is down to 3.1 liters per 100 kilometers (75.8 mpg US) for the combined cycle, making the new Corsa the most economical Opel presently on the market and the most economical diesel available. Sales in Germany begin in March.

The fundamentally revamped diesel engine with 70 kW/95 hp and maximum torque of 190 N·m (140 lb-ft) at 1,750 – 2,500 rpm in combination with a latest generation turbocharger allows for superior drive and acceleration even at low revs while simultaneously being extremely quiet. A water pump, operational when required, and a variable oil pump contribute to the low consumption and CO2 values.
Specially developed low-rolling-resistance tires and the Opel braking energy recuperation system also play an important part.
The five-speed Easytronic 3.0 weighs less and has lower internal friction than a conventional automatic transmission. It combines the advantages of a comfortable automatic transmission with the efficiency of a manual transmission. Easytronic 3.0 automatically selects the most fuel-efficient gear based on a manual transmission optimized for smaller engines and enables economical driving. The automated transmission is combined with Start/Stop technology that reduces fuel consumption even further especially in urban areas.
The Opel engineers developed a special gearwheel set for the automated transmission. The wide gear ratio spread of the five-gear wheel set reduces engine running speed, for example during highway travel, to a pleasant noise level. Furthermore, Easytronic 3.0 also offers a creep mode similar to that of an automatic transmission for slow maneuvers. The transmission has a special start function for rapid starts and sporty acceleration.
The latest generation of Easytronic enables quicker and smoother gear shifts. This optimization was made possible by a new actuator along with improved sensor and control technology and by the completely revamped manual base gearbox.
In addition to automatic mode with an electro-hydraulic actuator taking over shifting and clutching operations, Easytronic 3.0 also offers manual gear shifting via push and pull operation of the gearshift.
Hmm, my experience with robot-shift of manual gear boxes has not been the best. It is not nice when the clutch disengages just as you need power to e.g. cross the street faster than anticipated.
I hope they have done better than what I have tried so far.
Other than that, automated-manual is the way to go for economic driving; superior mechanical efficiency and 'disciplined' gear change strategy. And with an even longer top gear as a cherry on the top.

I wonder what mileage it will get in operation - 50mpg ? 60 ?
Hardly more than that.

Yeah, as much as I would love to see this engine over in the US, its never gonna happen.

Make it a diesel hybrid, then you might get the mileage the 1999 PNNV cars did.

If you could get 75 mpg (US), you wouldn't need to make it a hybrid - it would be too expensive.
Even if you get 60 mpg, you could still just go with it as it is.
I would consider it more important to make it affordable than perfect.
