General Motors has announced the launch of two new engines that will be used in some of the automaker’s Euro-spec vehicles. The new powerplants include a family of four-cylinder turbocharged engines — ranging in displacement from 1.0L to 1.4L — and a 1.6L Compressed Natural Gas unit. Both engines will make their debuts around the turn of the decade.
The new family of gas turbocharged engines will feature a turbocharger integrated into the exhaust manifold, full variable valve timing, thermal management, flow-controlled oil pump, and a reinforced crankshaft and connecting rod.
In 1.0L guise, the engine will kick out 120 horsepower, while the larger 1.4L unit will produce 140 horsepower. GM says that both engines should return an 8 percent increase in fuel economy, when compared to larger, naturally aspirated engines producing the same amount of power.
The 1.6L CNG engine is based on GM’s current 1.6L CNG powerplant, but will now feature a turbocharger. Output is rated at 150 horsepower, and the engine should emit 25 percent fewer CO2 emissions than a comparable gasoline engine.
The new 1.0L and 1.4L engines will bow in 2010 while the 1.6L CNG engine is slated for use in 2009. No word if either engine will make it to the U.S.

Wow… a whole 8%… that’s huge!
So instead of a 2.0L motor that burns regular gasoline and gets 25MPG… you will have a 1.4L turbo motor that burns premium fuel and gets 27MPG.
Cost vs savings analysis says… nope… not worth it.
The vast majority of American cars are too big and heavy to be pulled around by these little coke-bottle engines anyways.
GM would be better off de-tuning the LNF… dropping the boost to 10PSI… and using it in the small cars to get around.

We’ll probably see these in the next generation Aveo. The current Aveo gets around 30 MPG. Combined with GM’s two-mode hybrid system, this drivetrain could easily exceed 40 MPG.
As far as fuel goes, GM has already figured out how to run the 3.6L Cadillac V6 on 87 octane with a very high 11.4 compression ratio. This is mostly due to the Direct Injection system. Given the target market for these vehicles, I can’t see GM requiring 92+ octane for this motor.

A turbo Aveo with 140hp is something that I would be interested in. That would be a pretty fun little car considering how light it is.
Now if they only made the turbo into a seperate unit. Building it into the exhaust manifold just sucks for tuners.

Can you imagine if your old 1.0 litre Geo Metro had 120 horse? Now that I would pay $6,000 for.

You could probably slap a little mitsu turbo onto the ol’ Metro 3-cyl and get 120hp… $2000 for the car… $2000 for a turbo kit, install, and tune. Not bad… not bad.
