Ford is adding the SFE EcoBoost as a trim variant of the Fiesta subcompact automotive.
La — In a evaluate of the 2014 Ford Fiesta previous this month, I instructed waiting for the EcoBoost model, which Ford has promised will likely be to be had in just a month or two. At the los angels Auto convey, I proved myself right when Ford gave me a chance to pressure a 2014 Fiesta SFE with the EcoBoost engine.
This engine is a story unto itself, in that it’s a lot smaller, but much more powerful, than the Fiesta’s present engine.
Underneath the hood of a present era Fiesta, you are going to find a fuel efficient, however no longer very powerful, 1.6-liter four cylinder engine. The EcoBoost engine within the Fiesta I drove handiest has three cylinders displacing 1-liter, or 999 cc to be technical. But despite its smaller size and one less cylinder, the EcoBoost engine produces 123 horsepower — that is three more than the 1.6-liter engine. The larger difference comes in torque, the place the EcoBoost engine creates 148 pound-toes versus a hundred and twenty from the greater engine.
This three-cylinder engine measures less than a foot throughout.
Ford’s one-liter engine pulls off this seeming miracle thru pure expertise. Direct injectors spray fuel into the cylinders, the place it mixes with air and combusts in a very full burn. A small turbocharger — a Ford spokesperson mentioned the impeller is only one.5 inches broad — forces air into the cylinders at force, which leads to more power. The valves are timed for different engine speeds and prerequisites, growing top-rated intake and exhaust cycles.
However a turbo can also lead to power lag and surges.
Getting in the back of the wheel of the Fiesta SFE with the EcoBoost engine, I put the five-pace handbook transmission into equipment and hit the fuel. Even with two different passengers, the auto took off with quick acceleration. That 148 pound-feet of torque launched the Fiesta far higher than the 1.6-liter engine had within the previous instance I had pushed.
After I shifted up, on the other hand, the facility lagged, with little response to the fuel pedal. That power drop had extra to do with the transmission than the engine, because the 2d tools ratio was taller than I expected. Shedding again to first, I let the engine wind up unless the car was once at better speed, then up shifted. There was once slightly studying curve for the gearing.
Right through a half-hour force, I ran the Fiesta SFE EcoBoost up a limited-access highway on-ramp, accelerating for a traffic merge. I took it via all its gears, finding that I may drop down to 3rd when I wanted power at parkway speeds. I shot thru los angels visitors, finding the suitable gears to skip thru lanes, the infant-liter engine giving a whole lot of thrust for every maneuver.
The SFE trim Fiesta will also be had with the EcoBoost engine possibility.
An aggressive growl emanated from the engine compartment once I wound it up, however Ford had clearly spent a while insulating the cabin from the noise, as the sound was once pleasantly muffled. I failed to really feel any vibration from the engine, rather than what I would are expecting.
In fact, the truth that I was riding the guide transmission model of the automobile gave me good control over the facility, letting me wind up the engine when I wished all it had to give. The automobile will be available with an automatic transmission, which will behave very otherwise.
With the handbook transmission, the EcoBoost engine gets the Fiesta an EPA-rated 32 mpg city and 45 mpg freeway, that latter number the absolute best of any pure fuel automotive on the market. It’s an outstanding feat for one thing that answered so neatly.
Ford will have to have this new Fiesta in showrooms inside a couple of months. It’ll show up because the Fiesta SFE version, with the EcoBoost engine as a $1,000 option. In SFE trim, the Fiesta also features a few aerodynamic upgrades and low rolling resistance tires.
