Ford Fiesta
Ford continues to milk the benefits of turbocharging

The automotive industry is quickly embracing turbocharging technology for gasoline engines which was once relegated to sports cars and luxury vehicles in an effort to improve fuel efficiency. Now vehicles ranging from "lowly" Chevrolet Cruze compact sedans to Ford F-150s (as witnessed by our article earlier today) are jumping on the bandwagon. 

A little over a year ago, Ford debuted its Start concept car which featured a brand new three-cylinder EcoBoost engine. While the vehicle is (and likely will remain) a concept, the engine has now been approved for production

The tiny 1.0-liter three-cylinder engine is turbocharged (obviously) and features an offset crankshaft to help improve fuel economy. It also features a split cooling system to warm up the cylinder block before the cylinder heads. In addition, other EcoBoost staples like direct injection and twin independent variable camshaft timing are included. The engine also weighs less than the current 1.6-liter four-cylinder engine used in the Fiesta

All of this technology means that the tiny 1.0-liter engine puts out the same or better power as a normally aspirated 1.6-liter engine while achieving “much higher fuel economy and lower emissions”. 

“No one’s ever built a three-cylinder engine quite like this," said Joe Bakaj, Ford VP of Global Powertrain Engineering

“Consumers are telling us they want to buy affordable vehicles that get many more miles per gallon,” said Kuzak. “Our new 1.0-liter EcoBoost engine will give consumers looking for hybrid-like fuel economy a new, more affordable choice.” 

Ford isn't ready to provide EPA numbers for the 1.0-liter EcoBoost just yet, but the company said that it will get much better fuel economy than the already good 30 mpg city/40 mpg highway rating of the Fiesta with the 1.6-liter four-cylinder engine.

30mpg was done in the 80s without turbo

Ever heard of the Civic HX? That car is able to achieve 56MPG without a turbo.

Today's Hybrids are able to achieve 50mpg+ easily with the same driving technique used to achieve 30mpg for this Ford.

Lame really lame..

So bring that soda can on wheels around and do a crash test on it. Bet it won't earn a single star rating.

I get to call it a soda can on wheels, I test drive one.

We had a 76 Honda Civic that would get 30mpg or more but compare it to what is on the road today and you probably couldn't sell it at all. And once you added everything you needed to make it sell along with the emissions equipment required now it would either get around 20mpg or top out at 30mph.

Though it was a great little car, as long as you had short legs :)

wow only 56mpg ? I could get forever with my pedal bike. Since were going to make outlandish claims mines as good as yours.

No Civix HX ever got 56mpg under the current measurement system. I doubt anyone ever got 56mpg under the system used to measure mpg in the 90's either but if you meant going down hill with the wind at your back Im game to believe it. My wife's Civic DX was lighter and smaller than the HX and only got about 35 combined.

Talking about the new Ford though maybe you didnt read the article? The Fiesta with the small turbo 1L engine will beat the current cars 40mpg highway rating significantly...70 mpg sounds about right. It will also be making much more hp than the old Civic's ever did...meaning it might be ok to drive.

I understand this new Ford engine to have been co-developed with Mazda's new engine series prior to the divorce. Mazda is reporting a real world 65-70mpg highway figure without the turbo at a 1.3L sized motor. And it does it under this centuries measurement system vs fantasy island stuff from the 90's...
