Powertrain improvements net a 1 to 3-mpg increase for 2007 2.0-liter Ford Focus.

Customers will also notice enhanced performance.

Ford Motor - August 23, 2006


2007 Ford Focus 2.0L - changes to the engine SW along with new LRR Tires nets a 3-mpg increase in highway mileage.

Ford Motor Company’s razor-sharp focus on the consumer has prompted the company to make some dramatic improvements to the 2007 Ford Focus. Powertrain engineers concentrated on the 2.0-liter inline four-cylinder, improving fuel mileage across the board.

“The Focus engine was originally calibrated for emissions,” says Nicholas Schubeck, supervisor, Powertrain Calibration for Ford Motor Company. “We noticed during testing that we could get a lot better fuel mileage by making some adjustments to the calibration while still meeting emissions.”

The team increased the engine’s spark and revised the exhaust-gas recirculation and intake manifold runner control (IMRC) schedules. The IMRC is a device on the intake manifold that increases the velocity of the air going into the cylinder at low speeds. Increasing air velocity helps in the proper air-fuel ratios.

“The issue is that the system also creates a lot of pumping losses, which reduce fuel mileage,” says Schubeck. “By opening up the IMRC a lot earlier to reduce pumping losses, fuel mileage was increased.”

This change, along with tire improvements, accounted for a 3-mile-per-gallon improvement on the EPA highway fuel economy label for five-speed manual models, which now see 27 mpg in the city, 37 mpg on the highway. The 2.0-liter automatic delivers 27 mpg in the city, 34 mpg on the highway. For 2007, the base Focus models come equipped with 14-inch Hankook tires that offer better rolling resistance than the 2006 model.

Schubeck says customers will also notice an enhancement in performance. The extra engine spark improves acceleration, and the refinements to the engine have eliminated the hesitation that normally occurs when the air conditioning is is in operation.

27/37 FE isn't too bad for a 2.0L non-hybrid car. It's too bad Ford never invested in an inexpensive IMA-class hybrid system for small cars. The Fucus could then get mid-40s and still eb affordable.

Re: Powertrain improvements net a 1 to 3-mpg increase for 2007 2.0-liter Ford Focus.

Hi Ashen Grey:

___Just look up some of my previous comments about the Focus … The thing I am so ticked about is it took them over 5 years to do $20.00 worth of work (if that!) for FE that comes close to the Civics/Corolla’s of old. Even with the tweaks, they are again behind because now they are fighting the Corolla w/ a stick at 41 highway and the new Civic at 40 highway with an Auto! How many 03 Civics and Corolla’s were sold because they did get 3 – 4 mpg more then the Focus let alone the old Focus w/ a stick could just match my PZEV based Accord with an Auto! It is not like I spoke with people at Ford that had the ability to fix this but it all fell on deaf ears. 27/37 puts them in the ball park but again, they fell back to the minor leagues instead of the majors … New Mazda heads with an Atkinson lobe/intake for low load demand ala Civic’s 1.8 and they have a 41 - 43 highway locked up … Of course we will never see that all the while the next gen Corolla will come out with who knows what in terms of FE. Toyota pulled the new redesign after the Civic release saying back to the drawing boards boys but have promised 5% across the board on most of their lineup with the next gen designs … Do the math on today’s 32/41 based Corolla and you are approaching older Echo like numbers 34/43 with a 0 -60 time of ~ 8 seconds with a stick. If they Atkinson that 1.8 properly for 0 – 60 in 11 or so, expect to see 50 out on the highway and then everybody is dead including Honda, let alone Ford.

___I talk/wish a lot but the car manufacturers do not push FE like this for some unknown reason??? The first manufacturer that does however is going to make those that cannot afford a hybrid or the upcoming small and clean diesels very very happy … I would not expect Ford or GM to take the lead unfortunately and because of this, they will be that much closer to bankruptcy before they actually figure it out more then likely

___Good Luck

___Wayne
