Listen: Upcoming Ford Focus ST to employ sound symposer

While BMW employs a digitally sanitized/perfected sound file to give M5 owners the proper sense of aggro urgency when motoring at pace, Porsche went a little more organic with its employment of a sound symposer to feed the 911's flat-six growl into the cabin of the extra-refined 991. Essentially, the sound symposer is an electrically controlled diaphragm in a tuned sound tube that brings the proper engine noises into the passenger compartment. It can be opened and closed by the car's onboard electronics to offer snarl when you want it and serenity when you don't.

Bentley Continental GT3-R with 572 bhp V8 revealed

The Bentley Continental GT3-R arrives with a 572 bhp V8 As we reported last week, it looks like Bentley has decided to do a V8 take on the original Continental Supersports with the arrival of the Bentley Continental GT3-R, a lighter, more powerful Continental V8. Just like the original Continental Supersports, the Continental GT3-R loses its back seats and goes on a diet (down 100 kg on the V8S) and gets a retuned version of the 4.0 litre twin-turbo V8 producing 572 bhp and 516 lb/ft of torque together with shorter gearing to deliver a 0-60 mph in just 3.6 seconds (0-62mph in 3.8s). The GT3-R still comes with Bentley’s four wheel drive, but it gets torque vectoring too and a modified ESC and a chassis tuned for outright cornering ability to make the GT3-R Bentley’s most dynamic road car to date.
