The lightweight automobile has just fetched the top of the Gallardo line-up, launching in Australian market in July at a cool $525,000.

The new car, known as the LP 570-4 Superleggera, promises more with less fuel consumption, outlining a new standard for Gallardo performance.

It weighs less by more than 50 kilos and its 5.2-litre V10 knocks out 419kW for a 0-100km/h dash of 3.4 seconds, it can fetch a 200km/h speed by the time a stopwatch clicks 10.2 seconds, and it can charge all the way to 325km/h at the top end.

Andrew Smith of Lamborghini Australia posted his belief that the Superleggera can improve the previous model's sales figure as the world economy moves on the track of improvement.

"Sales of high-end luxury cars fell away a bit from mid-2008 to late 2009 because of the global financial crisis, the increase in the luxury car tax and buyer sentiment,'' Smith says.

Lamborghini says the engine is relatively economical because of its direct petrol injection system; the V10 has cut the fuel consumption and CO2 emissions by spectacular 20.5 per cent. It now averages 13.5 litres/100km and emits 319 grams of CO2 per kilometre.
