The new Ford Focus ECOnetic is expected to achieve 80 mpg along with emissions of less than 95 g/km CO2 when it goes on sale in the UK in early 2012.
The new Focus ECOnetic, which will debut next week at the Amsterdam Motor Show, is on target to be more fuel efficient than any other compact vehicle on the road today in Europe, including diesel, petrol and hybrid powered vehicles. It will be available in five-door and estate bodystyles.
To achieve its fuel economy, the new Focus ECOnetic employs the latest low-CO2 technologies in its powertrain, aerodynamics and driver information systems.
The vehicle is powered by a new 105PS version of the 1.6-litre Ford Duratorq TDCi diesel which has been optimised for enhanced fuel efficiency, with a new injection system and turbocharger, enhanced charge cooling and further friction reduction measures.
The Focus ECOnetic also benefits a number of additional low-CO2 features which have been developed specifically for this model including a unique aerodynamic package with an Active Grille Shutter, ultra-low rolling resistance tyres and a revised final drive ratio.
The new Focus ECOnetic incorporates the full range of Ford ECOnetic Technologies shared with other models in the all-new Focus line-up, including Ford Auto-Start-Stop, Smart Regenerative Charging, Ford Eco Mode and Shift Indicator Light.
The common-rail fuel injection system of the diesel engine has been completely redesigned, with new injectors controlled by a more powerful engine management system. The new injection system delivers more precise control and increased combustion efficiency.
To provide more accurate control of the charge air temperature and to deliver a cooler, denser charge, the intake system features a water-cooled intercooler in place of the standard air-to-air system.
Other new, or completely revised, features to enhance fuel efficiency include:
* New variable geometry turbocharger design
* Reduced engine friction from low-friction piston ring coatings and variable flow oil pump
* Additional reduction in engine losses from low inertia vacuum pump and asymmetric crank sprocket design
* Updated emissions system combining a diesel NOx-reducing catalyst with a coated Diesel Particulate Filter system
The 1.6-litre ECOnetic diesel is paired with Ford’s six-speed Durashift manual transmission. This transmission is a totally new high-efficiency design which has been optimised to eliminate frictional losses, and utilises special low friction transmission oil.
A revised final drive ratio has been selected to raise the overall gearing, reducing engine speed and offering improved fuel economy when cruising in top gear. Economy is further enhanced by fitting the latest-generation dedicated low rolling resistance tyres.
The ECOnetic model has been designed with a number of additional erodynamic features to minimise drag still further.
Much of the aerodynamic development was concentrated on smoothing the airflow underneath the vehicle, with the car featuring additional undershields and deflectors.
Aerodynamic performance is also improved by the use of special low-drag ECOnetic wheel covers, which are more streamlined than a conventional alloy wheel design.
The ECOnetic model features, as standard, the innovative Active Grille Shutter – an advanced new system that optimises aerodynamics by using vents to control airflow through the grille to the cooling system and engine compartment.
If air is required to cool the engine, the vents are opened; but if no airflow is needed, the vents are shut, thereby significantly reducing aerodynamic drag. When fully closed, the reduction in drag means that the Active Grille Shutter can reduce CO2 emissions by two per cent.
The Focus ECOnetic incorporates as standard the full range of low-CO2 Ford ECOnetic Technologies which are shared with other models in the new Focus line-up including Ford Auto-start-stop, Smart Regenerative Charging, Ford Eco Mode and Shift Indicator Light. In addition the Focus ECOnetic includes:
* Electric Power Assisted Steering
* Low-friction engine and transmission oils
* Low tension Front End Accessory Drive (FEAD)
* Thermal Management Systems to optimise warm-up
The existing Ford Focus 1.6 TDCi, which went on sale last month, and is available across all series, emits 109 g/km CO2 while returning 67 mpg.
