As if the excitement of our own dear Queen visiting wasn't enough, nor the Rugby World Cup final in neighbouring New Zealand, Adelaide is host to a green 'eco-car' test drive event this weekend.
Electric and hybrid cars from Audi, BMW, Honda, Mitsubishi, Nissan, Renault and Toyota will be available for test drives around a set 3.5km course around the city.
The event links up with the World Solar Challenge, which arrives in Adelaide this weekend. Organisers are keen to demonstrate how technology from the Solar Challenge vehicles is finding its way into production cars.
It estimates that within the next ten years, 10% of Australian vehicles will be either electric or hybrid.
