We knew that the 2013 version of Lamborghini Aventador was going to get a cylinder deactivation system to save a bit of fuel, but turns out it’s not the only fuel-saving feature the Italian hyper car is getting. Lamborghini has developed an auto stop/start system as well to complement the deactivation, in hope to arrive at a fuel-sipping Aventa. Not really!

The car has a V12 engine with a displacement of 6,500 cc. There’s only so much you can do to make it more fuel efficient. Lamborghini, with help from Audi of course, has come up with a new type of stop/start system called the ‘Supercaps’ which utilizes high-performance capacitors instead of regular batteries. This way they save a few kilograms and also manage to get a restart time of 180 milliseconds.

As for the cylinder-deactivation system, it only works below 135 km/h, and deactivates six of the cylinders. Despite all this, the Aventador hardly becomes a Prius, still struggling to do better than 16 liters per 100 km. But at least Lamborghini is trying.

More important changes for the 2013 Aventador include a revised suspension system for improve handling and comfort, and a new carbon package to make the car lighter.
