With all the focus on plug-in hybrids, electric cars, and hydrogen fuel cells, one could easily forget the merits of existing engine technologies. But next year, GM plans to introduce a 1.4-liter turbocharged engine that promises performance and efficiency at a very low price point.
Possible candidates for the engine include the Chevrolet Cobalt and Saturn Astra, though it could find its way into other vehicles. GM is also expected to add turbochargers to other small inline-four engines, since the upgrade would only cost $250 to $450 per vehicle, according to Automotive News.
But don’t think such engines will be limited to just hatchbacks and compact cars. Expect to see turbocharged four-cylinder engines in vehicles “no one could have ever imagined,” GM’s engineering boss Jim Queen said.
Automakers are becoming more interested in turbocharging in light of fuel economy concerns. Ford recently launched its EcoBoost V6, which promises V8-like performance, and BMW is in the midst of phasing out its 4.8-liter V8 in favor of a smaller 4.4-liter turbocharged V8, starting with the new X6.

it’s not a bad idea to start off with their smaller cars as those are optional engines in the Astra to begin with in Europe, without the turbocharger. I wonder when Gm will give us the optional Diesel version engines for the astra.

Just bring diesels, dammit. Turbo gas engines are not very efficient in real world use, kinda like a hyprid. Real people will always be in boost, especially if the engine is really small, like 1.4l. Unless it’s VVT & Direct Injected, and has sophisticated boost control software/hardware to eliminate lag, then it won’t be efficient OR very appealing to everyday drivers, and by then, just as expensive as a diesel, without the CO2 benefits.

i’m just worried about what other cars they want to put these engines into. the 2009 i-4 corvette.

It makes sense to go to the turbo in the midsize sedans, like the Aura. The 2.0T makes more power (260) than the 3.5, and gets much better mileage. Reliablitiy I guess is the issue at this point, but that shouldn’t be a big deal.

LOL @ “just recently BMW replaced the 4.8L V8 for a 4.4 turbo V8″ The words “save money” and “better fuel ecconomy” dont spring too mind.

Less weight more power, sounds good. Look at VW 2.0 Direct Injection motor, small and efficient. Wide flat power band, good torque, no turbo lag.
Doesn’t sound like the old turbos at all, sounds great to me.

GB; The 3.0 twin turbo was to replace small V8s. So I thought the new 4.4 turbo was to replace v12.
I have heard different media reporting it both ways.
Maybe TT V10 is on way for ultra premium offerings.

The VW turbo 2.0 is a killer engine. Done right, turbos are the answer

1.4 L turbo comes on FIAT 500. This car is smaller then Mini. Gasoline turbos don’t have that great of a record. Diesel engines are much more suited for turbos. Perhaps GM engineers can bust that nut.

LLN, where is the news in this? A few months ago it was said that GM was doing away with superchargers and looking at the turbos for Cobalt and others.

The 1.8T I-4 in my last VW was less efficient than the 2.5L I6 in my BMW. BMW is also a larger, slightly heavier wagon. The VW struggled to get 20mpg overall, and the BMW gets around 24 with the same driving. They were about equal on pure freeway driving, at around 30.

well autonut, when you combine more efficient technology with smaller displaced engines, in smaller lighter weight compact and sub-compact vehicles they can show significant gains in fuel efficiency and performance with turbo engines.
GM is doing it right with the 2.0L direct Injected turbo and inter-cooled Ecotec motors, and the 2.0L intercooled S/C Ecotec that were in the Cobalt SS/SC and Ion Redline’s got pretty crappy fuel mileage (in my opinion from having one as a daily driver). Turbos have more potential with smaller displaced engines, and while everyone may hate the HHR the HHR SS gets very good gas mileage for having the new LNF motor in it. I for one am certainly welcoming this news.

If you want to experience a real turbo try a 535d. Until then shut up.
Comment by Ironhide
You mean a real expensive, overcomplicated turbo. How is the BMW’s turbo more “real” than this one?
I can make retarded statements too. If you want to experience a real turbo drive a Dodge Ram 2500 Mega Cab Laramie with the Cummins Turbodiesel. That’ll crush the puny Bimmer.

thank you frylock350, OMG Ironhide yeah because this article is totally talking about 60k luxury sedans in the first place right? WTF are you smoking? that was the most retarded comment I’ve heard. Why don’t you do all of us a favor and shut up the retarded comments that come from you.

yeah it’s ok Ironhide you can admit you have a thing for underage girls… We won’t judge you Ha! Too late. How is my logic non-existent when you said originally that a real turbo is a 535d when we weren’t talking about anything like that to begin with? the article wasn’t even talking about Diesel to begin with. And it’s ok that you don’t want to admit your fetish for teenage pregnant girls, we all know it anyways.

If you put a Ram 2500 Mega Cab Cummins (a truly massive vehicle weighing well over 6500lbs) with a reinforced truck frame, monstrous and four wheel drive. Not some AWD system its 4WD (there is a difference) into a truck pull with a unibody Merc the Dodge will drag it around like it was a fisher price toy car… if it doesn’t simply rip the Merc in half (due to the fact that it can’t withstand the force the Ram is applying to it whereas the Ram will take it in stride).
But the point of my statement was that comparing a 1.4T gasoline motor intended for economy to a turbo diesel intended for an overpriced luxury car is ludicrous. Just as ludicrous as comparing a luxury AMG model to a work truck is.
Also what does somebody’s gender and pregnancy status have to do with the value of their comments/opinions? Please don’t degenerate in to childish insults.
SS4LIFE, I think of this as a victory for American automakers if the only things people can think up to trump their basic cars are German luxury cars. The G8 for example. 5 series and E-class vehicles are constantly brought up despite the G8 being an everyman’s non-luxury car.
