The new Focus Econetic is said to pave the way for some of Ford's technologies to be implemented into its core vehicle series in the near future, according to Dr Thilo Seibert, Manager CO2 Technologies for Ford of Europe. The new Focus Econetic boasts considerably improved CO2 emissions of 99g/km and 74.2mpg.
It is the first European Ford to benefit from a raft of new eco technologies including the Ford Auto-Start-Stop, Smart Regenerative Charging, and Ford Eco Mode.
The Focus Econetic uses the stop-start system, which was previewed on Iosis MAX Concept at the 2009 Geneva Motor Show. However, the car claims that without it, the Focus Econetic will manage 104g/km. The previous Focus Econetic model emits 114g/km of CO2. Powering the car is a 108bhp 1.6-litre Duratorq TDCi engine.
Ford has also given the Focus a slipperier shape; the Econetic is lowered by 10mm at the front and 8mm at the rear, with blanking plates at the front, helping to achieve a cd of 0.31. It also gets the latest generation Michelin Energy Saver 195/65R15 tires to lower rolling resistance.
Seibert added that to achieve these figures, Ford combined the proven approach of the original Focus Econetic model with even more detail improvements and all-new technologies.
The new 2010 Ford Focus ECOnetic features the new Ford Auto-Start-Stop system – making it the first Ford Europe model to do so. This new system combines automatic engine start-stop operation with Ford Focus ECOnetic's smart regenerative charging and advanced battery management systems.
It shuts down, albeit automatically, the car's engine when it is idle, such as when it is halted on a stop light. As soon as the driver takes action to move the vehicle, the system will restart the engine. This process saves the fuel that would have been wasted while the car is stationary.
Moreover, the new Ford Auto-Start-Stop system could reduce the car's fuel consumption and carbon dioxide emissions by up to five percent in mixed driving conditions, and by up to 10 percent in an urban setting and in heavy traffic situations.
Ford considered customer comfort in designing this advanced system, which is aimed at providing a consistent smooth and seamless starting and stopping performance that requires no changes in driver behavior. Once the new Ford Auto-Start-Stop system shuts down the engine, its electronic control unit will instantaneously ready the powerplant's systems for an immediate restart.
Ford has integrated a number of sensors that could detect when the driver initiates an action that would signify an intent to drive off once again, like pressing the clutch or accelerator pedal. Then, the system would quietly restart the engine almost instantly – at around 0.3 seconds.
Drivers would not be able to notice the entire stop-start process, which occurs even before they complete gear selection. Ford, of course, took action to support the increased number of engine starts.
Hence, the carmaker upgraded the starter motor with a high performance electric motor and installed a stronger pinion-engagement mechanism with lower noise levels. Moreover, Ford employed advanced battery technology to make sure that the main battery could handle the numerous charge-discharge cycles that come with stop-start operations.
