The Sound of Science: Ford Focus ST Features Active Sound Symposer

May 27, 2012

Discerning sports compact drivers not only want their engines to sing, they want them to roar. Ford engineers made sure the new Focus ST does both, with the help of a new twist on an existing technology.

Ford engineers added a special sound tube – called a sound symposer – to amplify the throaty frequencies enthusiasts crave in performance cars. Engineers worked to naturally amplify the specific lower range of engine frequencies found between 200 and 450 Hz that are most pleasing to performance enthusiasts through the use of a composite “paddle” that vibrates with intake air pulses.

While the sound tube concept has been used on Mustang in the past, the sound symposer used in Focus ST is unique because of its electronically controlled valve that opens and closes based on driver inputs – engine speed, accelerator pedal position and gear selection. In lower gears, the valve is mapped more aggressively, while in higher gears the effect is dialed back to enable quieter cruising. This isn’t possible with conventional, passive sound tubes. Part of the reason Ford made these changes is that on Focus ST, for the first time, the symposer is attached directly to the intake manifold (as opposed to between the manifold and air intake).

“For ST drivers, it’s not enough to have a car that is fast or feels fast. It also has to sound fast,” says Christopher Myers, Air Induction System engineer. “Part of this is the design of the exhaust, but we went further and engineered the symposer both to dial up the nice sounds the EcoBoost delivers under the hood but dial back the interior sound volumes at part throttle.

“The turbo gives us great power across the rev range, but it presents a special challenge from a sound perspective as it absorbs much of the beautiful engine music,” Myers adds. “The symposer helps us bring the throaty sounds that drivers love.”

The secret to getting this right was developing the perfect paddle to naturally amplify the ST’s great engine sound. Ford engineers tested several different paddles. Eventually, the supplier developed a paddle with the correct stiffness that yielded the best acoustic response and ultimately, the best “flutter” and low-end frequency sound.

An international team from suppliers of the intake manifold, battery tray, electrical hardware and software, and electrical connectors came together with Ford to accelerate development of the symposer. All in all, 30 engineers from five countries had to balance NVH, materials, manufacturing and assembly considerations to bring the symposer to life.

“The sound symposer gives the Focus ST an aural split personality,” says Lisa Schoder, Ford Focus ST Marketing manager. “In everyday driving, the car is composed and refined. But under full throttle, we unleash the sonic hounds. It’s a beauty and a beast.”

Among the more visible options will be the Tangerine Scream metallic color that will be offered exclusively on Focus ST as well as race-inspired Recaro seats with matching color accents.

Focus Adds Premium Titanium Model

September 19, 2011

The next-generation Focus is all-new for 2012 and has expanded its brand footprint with a larger series range and comfort, convenience and technology offerings that are unprecedented. The new range-topping Titanium offers small car buyers premium-level appointments and technologies.

Focus is powered by an equally new 2.0-liter gasoline direct-injection four-cylinder engine delivering up to 40 mpg on the highway, with a class-leading 160 horsepower and 146 lb.-ft. of torque.

Bringing a fuel efficiency improvement of 10 percent and 20 percent more horsepower than the previous-model Focus engine, this advanced unit uses Ti-VCT to increase responsiveness, boost fuel economy and reduce emissions.

With striking good looks and sleek profile, Focus is offered as a practical four-door or sporty five-door hatchback. Its smooth aerodynamic shape leads to a coefficient of drag as low as 0.295, besting both Chevrolet Cruze and Volkswagen Jetta.

Focus was designed and developed to meet stringent global safety standards. Starting with a body shell 30 percent stiffer than the 2011 model, Focus features next-generation airbags to tailor deployment to individual occupants and segment-exclusive Safety Canopy® curtain airbags.

For 2012, the traditional three series levels for Focus – S, SE and SEL/SES – are supplemented by an additional three variants.

An SE sport package is now offered, adding features an enthusiast will appreciate such as 16-inch painted aluminum wheels, rear disc brakes, sport-tuned suspension, leather-wrapped steering wheel and shift knob, cloth sport seats, black-out accent trim and SelectShift functionality when equipped with the six-speed PowerShift automatic transmission.

An available Super Fuel Economy package for Focus SE adds low-rolling-resistance tires, aerodynamically optimized wheel covers and rear disc brakes.

Taking Focus into premium small car territory, the all-new Titanium series offers comfort, convenience and technology features that are unexpected for this segment.

From dual-zone climate control, ambient lighting, sporty and stylish interior trend packages featuring two-tone full leather seats, and segment-exclusive active park assist, Focus Titanium will make customers downsizing from luxury cars and SUVs feel right at home.

2012 Ford Focus Active Park Assist Feature Eases Pain Of Parallel Parking

February 10, 2011

The substantial technology investment for the all-new, next-generation Ford Focus brings an unprecedented level of driver assistance features to its segment, including an advanced parking assist technology generally found only in larger, more expensive vehicles.

“Crowded urban parking puts additional pressure on the driver,” said Ali Jammoul, director, chassis engineering. “Focus gives buyers a compelling option in active park assist, designed to make parallel parking a breeze.”

Painless parallel parking

The new Focus offers available with active park assist, an advanced new system which automatically steers the vehicle into parallel parking spaces. The system uses two ultrasonic sensors (one on each side of the vehicle) to scan for large enough space between parked cars – these spaces can be just three feet longer than the overall vehicle length.

Once a suitable space has been identified, the driver is alerted and clear parking instructions are shown in the cluster display using simple text and graphics. The driver controls the accelerator and brake, and selects a forward or reverse gear, while the system turns the steering wheel automatically.

The standard front and rear parking sensors provide an audible warning to help the driver judge when the car is getting close to the surrounding vehicles. To assist accurate parking in tight spots, the system will ask the driver to move the vehicle backward and forward until properly positioned.

Fuller Ford is expecting the new 2012 Focus to arrive sometime around the middle of the year. As always, Fuller Ford offers Lifetime Free Oil Changes on ALL new vehicle purchases – in stock or factory ordered. Fuller Ford is the Cincinnati Tri-State Region’s leader for the hottest, cutting-edge, most fuel efficient vehicles available. Whether you are coming from Ohio, Kentucky, or Indiana, we are conveniently located right off of I-75, just west of downtown Cincinnati.
