New Ford Focus features 'advanced engine'
The 2011 Ford Focus will come complete with an acoustically tuned EcoBoost engine when it is released in March.
Its 1.6-litre EcoBoost drivetrain has received a symposer – a small device that channels unwanted engine noise out and transfers the wanted engine noise into the car itself.
It does so by receiving engine noise frequencies as opposed to those of the turbocharger which is a less desirable noise. It then channels the engine noises through a valve and into the cabin.
Ford engineer Ralf Heinrichs said: “We originally developed this technology for the 2005 Focus ST. It is also a feature on the Focus RS and Focus RS500. Both these vehicles have a very high sound feedback or large sound window due to aggressive symposer tuning.
“The 1.6 EcoBoost in new Focus is more moderately tuned but still delivers much more feedback than the current Focus."
The 1.6-litre EcoBoost engine is also one of the most technologically advanced in Ford’s range thanks to a high-pressure direct injection system, a low-inertia turbo and twin independent variable cam timing as well as the innovative symposer.
The addition of the symposer will not negate the good work done by the engines efficient and economic technologies that deliver the power of a larger engine with heavily reduced CO2 emissions and fuel consumption figures, says Ford.
New Ford Focus offers will begin in March when the hatchback hits the UK and the estate version will follow suit when it goes on sale later in the year in June.
