This week's motoring highlights

With the end of the week fast approaching, we thought it time to recap the biggest motoring stories of the past seven days.

For Australia, Mark Webber’s decision to retire from Formula 1 probably heads the list, but for petrol heads there’s plenty of new car action including the all-new Mazda 3, Porsche 911 and a boutique supercar from Monaco.

The Le Mans 24 Hours also gets a look in, as do lightning fast electric cars.
