2013 Lamborghini Aventador adopts cylinder deactivation and stop-start

The Aventador's stop-start system uses high-performance capacitors known as 'supercaps' to restart the engine within 180 milliseconds after the driver motions to take off from rest. Despite the extra technology, Lamborghini says the system actually delivers a weight saving of three kilograms.

Combining with the stop-start system is the Sant’Agata Bolognese-based manufacturer’s all-new cylinder deactivation system (CDS). Under low load and at speeds of less than 135km/h, the CDS deactivates one of the Aventador’s cylinder banks, effectively allowing it to run as a six-cylinder engine.

Lamborghini says the CDS is virtually imperceptible to the driver and has no negative impact on the driving experience, and insists the full power of the 515kW/690Nm 6.5-litre V12 is back online with the slightest touch of the throttle pedal.

Together, the two efficiency-enhancing systems reduce the Lamborghini Aventador’s combined cycle fuel consumption by seven per cent to 16.0 litres per 100km and cut average CO₂ emissions from 398 grams per kilometre to 370g/km.

The cylinder deactivation technology is at its most effective at vehicle speeds of around 130km/h, when it delivers fuel consumption and emissions savings of up to 20 per cent.

Lamborghini has also further refined the Aventador’s chassis set-up for 2013, adding stiffer springs and retuned dampers for sharper, more precise handling and a more comfortable ride.

New ‘Dione’ forged alloy wheels are now available, as is an optional carbonfibre package that extends the lightweight, high-strength material to the front spoiler, air intakes, engine cover panel, powertrain cladding and interior accents.

The Lamborghini Aventador LP700-4 supercar is priced from $754,600 in Australia.
