Back in July we reported Lamborghini was working on new cylinder deactivation technology for the Aventador to help it achieve better fuel economy numbers. Turns out we were right. Lamborghini just announced a new engine stop-start system and cylinder deactivation for the 2013 Aventador.

Lamborghini isn't taking the typical route of stop-start systems, rather it is using an innovative new technology which features high-performance capacitors called supercaps. This technology allows the engine to achieve extremely fast start-ups after shutting down at a stop light, enabling the engine to achieve full V-12 power in just 180 milliseconds. Mazda is employing something similar in its 2014 Mazda6.

For 2013, the Aventador also receives cylinder deactivation which will shut down one cylinder bank, essentially making the large V-12 engine a very large inline-six under light loads. The system is enabled at speeds up to 83 mph, under light loads. Lamborghini says the system is virtually imperceptible to the driver, with no negative impact on the driving experience. Both emissions and fuel consumption can be decreased by as much as 20 percent at highway speeds of around 80 mph.

Lamborghini has also modified the Aventador's handling, while improving the ride and comfort. The changes are thanks to stiffer springs and optimized dampers. A new Dione wheel design is also available for 2013.

While we aren't sure Lamborghini Aventador owners are too concerned about fuel economy and emissions, we are sure they'll enjoy the improved ride.
