When the new Ford Focus ST accelerates, it’s nowhere near as noisy as expected due largely to the device called the “active sound symposer.” Automakers always aim find the balance between sound and sight, just like what the Ford Focus ST has achieved. The symposer has the appearance of a sound tube that was formerly used on cars like the Mustang.
It’s more advanced but it works the same way of pumping sound from the engine to the interior. It is directly attached to the intake manifold and pipes in a particular frequency range (200 to 450 Hz) into the cabin. The symposer comes with an electronically-controlled valve that opens and closes according to several factors such as the engine speed, throttle position, and gear selection.
The valve is intended to be more aggressive in lower gears and more passive in higher gears for quieter freeway cruising, which means that it celebrates the best of both worlds. The Focus ST has a 2.0-liter EcoBoost turbo-four engine, which produces 252 hp of max output and 270 lb.-ft. of peak torque.
But even with this high performance, it offers a pleasant muscular baritone soundtrack due partly to the symposer. “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 2013 Ford Focus ST will be the first car from Ford which integrates a collection of advanced and sport-oriented technologies that have been previously unavailable to North American customers, including the active sound symposer. It also comes with a unique sport suspension system that combines several never-before-seen technologies.
Moreover, the electric power-assisted steering (EPAS) on 2013 Ford Focus ST is now standard and is enhanced with torque steer compensation. The Focus ST also comes standard with distinct 18-inch Y-spoke ST wheels. In addition, the Focus ST is fitted with sideskirts and spoiler in the rear section. Inside, it features the SYNC with MyFord Touch, a Sony Audio System, HD Radio as well as 10-speaker surround sound system.
The 2013 Ford Focus ST will have a price tag of $24,995. A customer who will order a new Focus ST between May 1 and August 20, 2012 will eligible for the GoPro HD Hero2 Camera System, which a driver can use to capture a spirited drive or Focus ST track day. Customers will receive the camera after vehicle delivery.
