2010 Ford Fusion Hybrid Driving Impression – Fuel Economy at its Finest
While it is true that Japanese automakers Honda and Toyota saw the potential of gasoline-electric “hybrid” technology earlier, invested heavily in it sooner and brought it to market first, it is also true that the top two U.S. makers have assumed hybrid fuel-efficiency leadership as of 2009 with their own state-of-the art technology. While GM is offering fairly affordable mild hybrid sedans and more expensive, high-tech 2-Mode hybrid SUVs and trucks, Ford has redesigned its already excellent parallel hybrid system, and is expanding its availability to the substantially upgraded 2010 Ford Fusion and Mercury Milan mid-size hybrid sedans.
The EPA estimates for the ultra-fine new Fusion and Milan Hybrids are an impressive 41 mpg city and 36 highway, which beats Toyota’s ‘09 mid-size Camry Hybrid by eight and two mpg, respectively. They are, Ford says, the most fuel-efficient midsize sedans in America.
The conventional Fusion and Milan, nicely restyled and much improved for 2010, offer the mid-size segment’s best gasoline four-cylinder fuel economy, more powerful available V-6s, class-exclusive technologies, including blind spot detection and warning with cross traffic alert and Ford SYNC, and more total passenger and luggage capacity than the Camry. The Fusion’s new look is more upscale, sportier and aerodynamically slicker. But the most exciting news is this all-new Fusion Hybrid. Together with its Mercury Milan Hybrid counterpart, it joins the Ford Escape and Mercury Mariner (compact SUV) Hybrids to double both the size and volume of Ford Motor Co.’s hybrid lineup.
Among this next-generation system’s key features are an ultra-efficient new 2.5-liter four-cylinder “Atkinson cycle” engine good for 136 lb and 155 hp.-ft. of torque mated to an electronically-controlled continuously variable transmission, or “e-CVT.” Intake Variable Cam Timing (iVCT), enable seamless transitions from gas to electric and vice-versa, while both spark and cam timing are varied according to engine load to optimize efficiency and emissions. Enhanced electronic throttle control reduces airflow on shutdowns, which reduces fuel need on restarts, and a “wide-band lambda sensor” analyzes air-fuel ratios and adjusts the lean/rich mixture to keep the system in balance and minimize emissions.
The new 275-volt nickel-metal hydride (NiMH) battery is smaller, lighter and optimized to produce 20 percent more power. Cooled by cabin air, its improved chemistry allows it to run at higher temperatures, and an added variable voltage converter boosts voltage to the battery to operate the motor and generator more efficiently. A “smarter” climate control system with an electric air-conditioning compressor minimizes engine usage by running it only as needed for heating and cooling.
The brake system delivers full regenerative braking (when the drive motor becomes a generator), backed up by friction braking as needed, to capture nearly 94 percent of the energy normally lost through friction in braking and send it back to the battery. And, as we noticed during our drive, it delivers improved brake pedal feel compared to the previous system.
The hybrid system also allows the Fusion and Milan Hybrids to operate longer at higher speeds in electric mode than competitive systems. They can run up to 47 mph in pure electric mode, approximately double the speed of some competitors. “Because our hybrid can run at a much higher speed in electric mode, you can do so much more in city-driving situations,” says Ford Hybrid Applications Manager Gil Portalatin. “Under the right conditions, you can drive in your neighborhood or in mall parking lots without using a drop of gasoline.” With the 41 city and 36 hwy ratings, Fusion and Milan Hybrids can achieve a driving range of over 700 miles on a single tank of gas.
It uses two high-resolution, full-color liquid crystal display (LCD) screens flanking the speedometer that can be configured to show different levels of information. The approach is multi-layered: A tutorial mode helps drivers learn about its instruments and the system, while tech enthusiasts will enjoy detailed gauges that help them become more efficient. The system even “grows” vines and leaves on-screen to reward efficient driving.
Drivers can choose one of four data screens: The basic “Inform” screen displays battery charge and fuel level status; “Enlighten” adds an electric vehicle mode indicator and a tachometer; “Engage” adds engine output power and battery output power; and “Empower” adds power to wheels, EV power threshold and accessory power consumption. All levels can show instant fuel economy, fuel economy history, odometer, engine coolant temperature, transmission gear and trip data?fuel economy, time-elapsed fuel economy and miles to empty. There’s even an engine coolant temperature indicator that turns green when the engine is warm enough to allow engine restart and shut-off for full EV operation.

 TwinTech technology allows you to hook up two units for added output. View larger. |
Powerful Inverter System Delivers Cleaner Electricity
The EF2000iS is built around an innovative inverter system, which is able to deliver higher-quality, cleaner electricity than competing generators. It produces energy in the form of pure sine waves, which are cleaner and more reliable than most commercial power sources.
In simpler terms, this means that you’ll be able to confidently power delicate machinery without having to worry about the damage caused by unrefined energy. An electrical overload breaker is also included, to prevent generator damage in case of an unexpected overload.
Smart Technologies for Optimal Fuel Efficiency
The EF2000iS is exceptionally fuel efficient, able to run for up to 10.5 hours without refueling when in Economy mode. Its OHV engine runs reliably and dissipates heat efficiently, allowing for both a long life and optimal fuel consumption.
With its Smart Throttle Load feature, the generator is able to dynamically adjust engine speed depending on output, resulting in greater overall fuel efficiency. The generator also features an exclusive dual coil alternator stator, which lowers engine speed and reduces total fuel consumption.
Ergonomic, User-Friendly Design
Weighing 44 pounds, the generator is ultra-portable and features an easy-to-carry design. It has a convenient, centralized control panel, which allows you to easily access all of the generator’s features at the push of a button. It also starts up responsively due to its auto-decompression system, which reduces compression and makes start-up less difficult.
For added convenience, the EF2000iS is able to recharge batteries with its 8A12V DC output, making it ideal for RV, auto, and boat owners. You can even hook up two EF2000iS units for added output, thanks to TwinTech technology. And you won’t have to worry about engine damage due to low oil levels: an oil-watch warning system constantly monitors oil levels and lets you know when an oil change is needed.
Noise Reduction for Quiet Operation
The EF2000iS uses noise reduction technologies to ensure the quietest operation possible. Featuring a special sound-blocking design, the generator has noise-absorbing glass wool construction, which helps dampen noise even during heavy operation. Along with the EF2000iS’ super-quiet muffler and vibration-isolating feet, it helps keep noise to a minimum.
The EF2000iS is backed by a two-year warranty.
