New Ford Focus Econetic delivers 89g/km CO2TDCi diesel makes Focus most efficient non-hybrid
09 September 2011
Ford has announced new Focus Econetic and Fiesta Econetic models, which promise significantly improved fuel economy and reduced CO2 emissions.
The pair will debut at the 2011 Frankfurt Motor Show next week alongside a 1.0-litre, three-cylinder Focus Ecoboost. Together, they herald a new generation of Econetic models that will see half of all Fords sold sporting this green designation by the end of 2012.

Ford Econetic tech for Focus and Fiesta
The new Ford Focus Econetic is claimed to deliver a remarkable 83.1mpg, combined with 89g/km CO2 emissions.
That matches the most efficient conventional Toyota Prius for CO2. It also eclipses the Prius for overall fuel economy – enough to allow Ford to claim this Focus is the most efficient non-hybrid family car available (the forthcoming Toyota Prius Plug-in Hybrid claims as little as 49g/km CO2, hence the non-hybrid proviso).
The Fiesta Econetic, meanwhile, returns a claimed 85.6mpg while emitting just 87g/km CO2 – extremely impressive, but not quite good enough to wrestle the supermini efficiency title from the 85g/km, 88.3mpg Kia Rio.
Extensive changes for 1.6 TDCi
Under the bonnet of both new Fords is a development of the 1.6-litre TDCi turbodiesel engine.
This features an entirely revised common rail injection system - with new eight-hole injectors and advanced engine management for more precise combustion, plus a new charge-cooler system that replaces the standard air-to-air intake.
Further detail modifications include extensive friction reduction, a low inertia vacuum pump, variable flow oil pump and asymmetric crank sprocket. This is in addition to the electric power assisted steering, low-friction engine and transmission oils, and low rolling resistance tyres.
Power output is 93bhp for the Fiesta and 103bhp for the Focus – the difference mostly down to the variable-geometry turbo used on the Focus in place of the Fiesta’s fixed geometry item.
Focus gets NOx trap and active aero
The Focus also becomes the first Ford diesel to feature a ‘NOx trap’. This not only reduces harmful nitrogen oxide emissions – which cause acid rain, amongst other environmental damage – but the leaner combustion process further improves the vehicle’s efficiency.
Both models also feature stop-start – a first for any Fiesta, and a technology that will be available on every Ford model line by the end of 2012. Ford Eco Mode gives the driver a visual indication of how economically they are driving, as well as offering helpful tips on how to improve.
In terms of aerodynamics, the Focus incorporates an active grille shutter. This automatically changes the grille opening depending on the cooling requirements of the car. It has no less than 16 possible positions, and the reduction in drag when fully closed lowers CO2 emissions by 2%.
The Focus is equipped with a low-friction six-speed manual gearbox; the Fiesta a five-speed 'box.
30% drop in CO2 by 2020 promised by Ford
Both of these new cars are a key part of Ford’s overall CO2 reduction strategy. This also includes Econetic models featuring 1.0-litre and 1.6-litre Ecoboost turbo petrol engines, an electric-only Focus and hybrid variants of the C-Max.
The ultimate aim is a 30% reduction in range CO2 levels by 2020, compared to 2006 levels. With an 11 per cent fall achieved so far, Ford believes it is well on target to achieve this goal. They predict another 10g/km overall drop coming within the next two years.
There's no word on pricing or specific UK availability yet, but we expect more info at the Frankfurt Motor Show, where further details of the 1.0-litre Ecoboost Focus should also emerge.
