It doesn't matter if you produce supercars, subcompacts, or semi trucks, U.S. and European governments are clamping down on fuel economy and emissions. While hybrid powertrains becoming a popular option, even in the hypercar realm, more traditional high-performance machines are being forced to get creative.
Lamborghini (which just purchased Ducati, allegedly in part to improve its corporate average fuel economy), is reportedly set to apply features like cylinder deactivation and stop/start to its Aventador supercar. According to Auto Motor und Sport, for 2013, the 6.5-liter V12 brute will include CDS, or "Cylinder Deactivation System" which will allow the Italian supercar to run on six of its 12 cylinders. Additionally, the engine will benefit from stop/start system that employs a capacitor rather than a traditional battery. The report says that the capacitor is seven pounds lighter than a battery can charge up more quickly and the system starts the engine up in a mere 180 milliseconds. For reference, an average stop/start system takes about 250 milliseconds, while the Ferrari system takes 230 milliseconds.
The report says that the combination of the cylinder deactivation and stop/start will result in a 20 percent increase in fuel economy for the Aventador, which currently returns 11 miles per gallon city, 17 highway.
Other updates for the 2013 Aventador include a new instrument panel that enlarges numbers on the speedometer and tachometer and the option for more carbon fiber bits, including the engine cover. According to the report, the updated Aventador may bow at the 2012 Paris Motor Show this September.

 

Sweeeeeet...

 

what about on start up ? will it it start with 6 cylinders ? if so it will sound like riced honda

 

I'm sure they have that figured out. I can't imagine it will sound like an accord at startup

 

I believe it will start with all cylinders
Just deactivate for highway cruising

 

How bad will that be? I'm sure it can be turned off. Will have a 2013 aventador next week so I'll check and let you guys know

 

Thanks , i'm just curious if it will be like Auto/Start button on the console you turn it off and it will stay forever off till you turn again or you need to turn every time you re-start a car , i have similar system in my BMW X6 and its very annoying

 

The stop/start systems being put on these cars (like the Panamera Turbo too) is just so ridiculous. The fact they're putting a system on these cars that will maybe improve fuel economy by .001% is just a stupid and ridiculous gimmick.

I've driven cars with this before and I find the technology to be really annoying for no other reason than I hate the feeling of the engine shutting off and restarting. This is the dumbest thing ever to put on these types of cars.

 

My feeling is that putting these systems on high performance cars is only adding to the possibility of things going wrong. I wonder how long it will be before reports surface of cars not restarting, or getting stuck running on six cylinders. I already heard one story of a 991 with 40 miles on it leaving the driver stranded when the car wouldn't restart. Imagine the likelihood of this happening 5 to 10 years from now.

 

I do not believe you understand the real reason manufacturers are doing this... This is not a gimmick, this is manadotry CAFE standards that are being enforced by European and US governments! They have no choice. It is hybrid technology or this! All Ferraris including my 458 starts off in Automatic every time you start the car! It is annoying to have to put it in manual mode every time MANUALLY! Why? CAFE standards! to reduce corporate fuel consumption and CO emissions.

Luckily for the buyers, both the cylinder deactivation and stop-start can be turned off in the Aventador!

 

Have to wait a few days to see it
