The next update to the Lamborghini Aventador will get environmentally responsible features like automatic-start-and-stop, and cylinder deactivation system. Recent tightening environmental regulations in Europe and the United States have prompted even supercar manufacturers to adapt measures to improve fuel efficiency and reduce emissions. 

According to Sweden-based Auto Motor und Sport, who managed to find sales materials sent to dealers that, the new proprietary 'Start-Stop' system makes use of capacitors to draw power from instead of the battery, saving three kilograms of weight; the system also boasts of a quick restart time of 180-milliseconds compared to an industry average time of 250-milliseconds. Ferrari's system takes up to 230-milliseconds.

The Cylinder Deactivation System (CDS) meanwhile allows the 6.4-liter V12 engine to run on 'V6 mode', shutting off the six other cylinders while the car is on highway cruising speeds of up to 135 km/h.  The system reportedly saves up to 20% of fuel at the optimal speed of 130 km/h.

The improvements result in a reduction of fuel consumption of 1.2-liters per 100km from 17.2 to 16, while CO2 emissions have also been reduced from 398g/km to 370g/km.

Other additions to the 2013 facelift will include a new instrument panel with larger speedometer numbers, carbon fiber interior trims, new carbon fiber aero kit, a carbon fiber engine cover option to replace the transparent cover, new wheel design and an improved suspension system which features stiffer springs and retuned damping.

The report also speculates the possible unveiling of the 2013 Lamborghini Aventador this September at the 2012 Paris Auto Show.
