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.

Driverless 'pods' to hit Milton Keynes

DRIVERLESS cars will transport people through the streets of a British town in a £1.5 million project aimed at boosting green technology. From 2015 an initial batch of 20 driver-operated "pods", which will be able to carry two people, will be run on designated pathways separated from pedestrians in Milton Keynes. But by mid-2017 it is planned that 100 fully autonomous vehicles will run on pathways alongside people, using sensors to avoid collisions with obstacles.

Olympian Hoy dreams of racing at Le Mans

SIR CHRIS HOY is planning a competitive comeback in 2016, with the Le Mans 24 hours race the target rather than the Rio de Janeiro Olympic Games. The 38-year-old is Britain's most decorated Olympian with six gold medals, including two at London 2012, and has won 11 world titles. He announced his retirement in April 2013, but his passion for motor racing and competition will be fulfilled after agreeing a deal with Nissan, which will see him compete in the 2014 British GT Championship.
