The new Ford Focus ECOnetic five-door, revealed at the 2009 IAA Frankfurt Motor Show in September, is available with a new optional Ford Auto-Start-Stop system that was previewed on the Ford iosis MAX Concept at the 2009 Geneva Motor Show.
Irrespective of whether Auto-Start-Stop is specified, the new Ford Focus ECOnetic has Smart Regenerative Charging and Low Tension FEAD (Front End Accessory Drive), technologies that are new to the Ford of Europe product line-up, and which combine to deliver lower emissions and better fuel efficiency and pave the way for future powertrains from the blue oval.
Power comes from Ford's 109 PS (80 kW) 1.6-litre Duratorq TDCi engine with standard coated Diesel Particulate Filter (cDPF). Target average CO2 emissions for the Auto-Start-Stop equipped model are as low as 99g/km, with a combined fuel economy of 74.2mpg and 104g/km for the standard Focus ECOnetic.
The new Ford Focus ECOnetic is also the first vehicle to feature the new Ford Eco Mode system as standard. An all-new driver information system, Ford Eco Mode, helps to educate the driver to achieve improved real-world fuel economy.
Dr. Thilo Seibert, manager CO2 Technologies for Ford of Europe, said: "To achieve these impressive figures, we combined the proven approach of the original Focus ECOnetic with even more detail improvements and all-new technologies.
"The new Focus ECOnetic is particularly significant as it paves the way for some of these technologies to be implemented into our core vehicle series in the near future."
The new Focus ECOnetic five-door is the first European Ford to offer a new Ford Auto-Start-Stop system, which combines automatic engine start-stop operation with smart regenerative charging and advanced battery management systems.
The Ford Auto-Start-Stop system automatically shuts down the engine when the vehicle is at idle, at a traffic light, for example, and restarts the engine when the driver wants to move off, saving the fuel wasted at idle.
The system is said to reduce fuel consumption and CO2 emissions by up to five per cent in mixed driving conditions. In an urban environment and in heavy traffic with frequent stops the savings could increase to as much as 10 per cent.
The advanced new Ford Auto-Start-Stop system has been carefully designed with customer convenience in mind, and to provide consistent starting and stopping performance that is smooth, quiet and seamless, requiring no changes in driver behaviour.
When the engine shuts down, the electronic control unit immediately prepares the engine's systems for an instant restart. An integrated system of sensors is then used to detect when the driver performs an action that signals the intent to drive off, such as pressing the accelerator or clutch pedal.
As soon as the driver prepares to move away, the engine starts quietly and almost instantly; it only takes the system around 0.3sec to fire up the engine. The process is near imperceptible, and happens before gear selection is completed.
To support the increased number of engine starts, the starter motor is upgraded with a high performance electric motor and a stronger pinion-engagement mechanism with reduced noise levels.
Advanced battery technology is required to ensure the main vehicle battery copes with the frequent charge-discharge cycles common with stop-start operation.
The new Focus ECOnetic also uses advanced technologies to ensure that the battery is kept charged in the most efficient way.
A Smart Regenerative Charging system increases the alternator output when the vehicle brakes or decelerates. This converts the kinetic energy of the vehicle into electric energy without having to use additional fuel.
The ‘free’ electric current is used to recharge the battery, so that it can be used by the electrical systems at a later stage.This could be when the engine is switched off during a stop-phase, but can also be when the generator is operating in a less efficient mode.
The battery has an advanced management system that continually monitors its status and communicates with the Ford Auto-Start-Stop system, so that the regenerative charging feature can charge the battery in the optimal way. The start-stop system knows how much battery charge is available, so that it can leave the engine running if the battery does not have a sufficient level of charge.
In order to offer even greater versatility to cost-conscious ECOnetic customers, Ford is also launching additional five-door and estate versions of the new Focus ECOnetic without the integrated Ford Auto-Start-Stop system.
Available with Ford's 1.6-litre Duratorq TDCi engine with standard coated Diesel Particulate Filter (cDPF) in both 90PS and 109PS power ratings and in a choice of five-door and estate bodystyles, these versions offer the full range of the latest Focus ECOnetic technology, with the single exception of the start-stop functionality.
"From the very beginning of Ford's ECOnetic approach it has been our clear intention to offer our customers affordable eco-technology, and to also pave the way for the possible integration of these technologies into the core vehicle programmes," Dr. Seibert said.
"With its new comprehensive set-up, the new Focus ECOnetic offers exactly what it takes: versatility, latest level technology and – regardless of version – excellent CO2 and fuel economy figures."
