Car tech: Ford announces 1-litre Focus as ST goes global

Ford Focus STFord will feature a 1.0-litre, three-cylinder EcoBoost engine in the Focus and C-MAX in 2012, followed by the B-MAX soon after. The engine is the latest addition to the global family of EcoBoost engines which currently ranges from 1.6 to 3.5 litres.

The 1.0-litre EcoBoost engine will be the smallest currently produced by Ford, but its engineers say it delivers power and performance to rival a traditional 1.6-litre petrol engine while emitting less than 120g/km CO2 in the Focus. It will be available in 99 and 118PS configurations, and will develop 125bhp.

Ford is keen to point out the 1.0-litre EcoBoost has been developed with refinement in mind, and it will set itself apart from noisy three-cylinders currently in production. Engineers at the Dunton Technical Centre have deliberately unbalanced the flywheel in order to counteract the engine configuration and minimise natural vibrations of the three-cylinder design.

The latest advancement in its downsizing programme will make a huge impact in Ford’s drive to reduce average CO2 emissions across the range.

At the other end of the market, Ford announced its ST performance range will become a global brand as the Focus ST hatchback and estate were unveiled. The latter – a surprise debut at the show – is expected to appeal to European markets not traditionally known for their love of hot hatchbacks.

Ford says the new Focus ST will be 20% cleaner and more fuel efficient than the old 2.5-litre car, but engineers have worked hard to endow the new engine with the character the previous model had in spades. It will feature a reworking of the sound symposer.

Jost Capito, director of Global Performance Vehicles said: “People loved the sound of the previous Focus ST. The physics and acoustics of a 5-cylinder engine compared to a 4-cylinder are very different, but like Beethoven and Mozart – both of whom created fantastic yet very different music – we believe the engine note of the new Focus ST will delight enthusiasts in the same way.”

It will be the first car to feature Ford’s Sport Steering System which will vary the steering rack to offer feel through bends but stability at high speed. Ford’s Electronic Power Assisted Steering features Ford’s Torque Steer Compensation system to allow drivers to accelerate hard and still find grip. Ford says the systems virtually eliminate the sensation of torque steer for the driver.

    I had a 1993 Daihatsu Charade GTti. It had been in production since 1987. It produced 99bhp from a 993cc 3 cylinder engine and had a 0-60 of 7.8 secs. It was turbo’d and intercooled. Ford rock…but Daihatsu did it 25 years earlier. Granted, emissions weren’t even measured then, so I cannot comment, but the basic engine (minus turbo) now sits in the C1/Aygo etc.

  2. It’s so disappointing that the Focus ST is losing the 5-cylinder engine, but I still have faith that Jost Capito and his team will do a good job with the new car.

  3. Oh I am so desperately waiting for this car. Ford rocks.
