Ford 1.0-liter EcoBoost engine shown to TorqueNews as a 123 HP cup holder
Ford invited TorqueNews to Denver, Colorado to have a look at the new 1.0-liter EcoBoost engine that will be featured in the 2014 Ford Fiesta later this year. The engine displaces less volume than the average soda pop, yet it produces more horsepower and torque, and has better fuel efficiency than an engine that's sixty percent larger.
On hand was a mockup of the engine (shown above) which helped Ford's representative, Paul Witt, explain how this high-compression engine, which fits into carryon luggage, does its magic.
First, let's look at how the engine performs in comparison to the current lineup of engines offered in the 2014 Fiesta. The 1.6-liter engine is most popular (and we drove one at the event for comparison) with either a standard five-speed (as we drove it) or an automatic transmission. It achieves 120 horsepower, 112 lb-ft of torque, 29 mpg in the city, and 39 mpg on the highway. In the ST EcoBoost 1.6-liter option, the Fiesta has 197 horsepower, 202 lb-ft of torque, and gets 26 mpg in the city and 35 mpg on the highway.
Now, compare that to the 1.0-liter EcoBoost which produces 123 hp, 125 lb-ft of torque (with 145 lb-ft available in short overboost spurts), with fuel economy at 32 mpg in the city and 45 mpg on the highway. All without adding electrification, expensive lightweighting, or other complex technologies to the mix.
The EcoBoost series of engines, which range from this new little 1.0L to the big 3.5L V6 found in the F-150, all operate on the same principle. It's similar to Mazda's SKYACTIV engine system, which was developed in cooperation with Ford.
The EcoBoost engines are high-compression engines, which means that they operate under higher pressure than standard gasoline engines, verging on the pressures found in diesels. Combine this high compression (which itself increases burn rate and decreases fuel consumption) with the advanced gasoline injection, turbocharging, variable valve timing (VVT), and precise electronic controls found in the EcoBoost series and you have extremely efficient engines that deliver a lot of power with little fuel use.
Going back to that Fiesta, this means that the 1.0L EcoBoost engine delivers better horsepower and torque than does the 60 percent larger 1.6L engine as well as far better fuel economy numbers. This gives the 1.0-liter-equipped Fiesta a best-in-class fuel economy rating, including highway mileage that beats some diesel and hybrid models like the Volkswagen Golf TDI and the Honda Insight hybrid.
It's no wonder automotive journalists gave the little 1.0L EcoBoost engine the International Engine of the Year award two years running (2012, 2013). It's amazingly small and very powerful. Ford says that the new 2014 Fiesta with the 1.0L engine will begin entering dealerships early to mid-summer this year.
