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.

      Ok, there seems to be some misinterpretation here. I'm sure the Lamorghini owners could not care less about what MPG their Aventador gets. However, I'm sure than Lamborghini the car companys cares a WHOLE HECK of a lot. If Lamborghini wants to sell cars in the U.S. and the EU then they must meet ever more stringent C.A.FE. regulations. This system isn't for the drivers its for the manufacturer. It's for Lamborghini's ability to continue to do buisness in 1/2 the world.

      actually think it's a pretty good idea. the start stop may add some weight but cylinder deactivation is really just CPU stuff. and having experienced how Hot these engines get at idle and slow speeds, deactivating half the cylinders and turning off the engine at stand still will probably be a huge improvement for managing the temp of engine bay. When someone is driving the car the way it was meant to be driven, you typically have a lot of airflow, even on tight twisty courses, but sitting in traffic at idle will cook stuff.

      I'm pretty sure you can defeat the start/stop and cylinder deactivation - otherwise it would be retarded.

      You guys mentioned Ducati getting bought by Lambo possibly for fuel economy reasons, and that sounds totally bogus. At least for the US CAFE standards, IIRC, its just for cars.

      Audi just purchased Ducati, not Lamborghini. And Audi and Lamborghini are part of VAG already. So the analysis here seems a bit off. Maybe VAG wants to knock down their CAFE numbers, but I have a hard time beliving that the few Lambos sold in the U.S. factor into that equation.

      I'm confused about these "stop/start" functions that many new cars seem to have. What have the manufacturers done to compensate for all of the extra potential wear & tear on these engines? Technically unless your vehicle has a electric oil pressure pre-pump every start of the engine is a "dry" start until the oil is circulated through the system. Granted this is very momentary (probably about 1 second) but this is where most of the engine wear occurs. In the course of 5 or so years with a "stop/start" system your engine could be potentially be subjected to tens of thousands additional starts. I can't help but think that this will increase maintenance costs such as flattening cams, starters & flywheels over the life of the vehicle. Like I said I really don't know what the manufacturers have done to mitigate this. Just thought I'd throw it out there to get some feedback.

        These stop/start systems have been around for more than 5 years, and I have yet to see some anyone complaining about increased wear. Lord knows that if there were AB would be reporting on it 24/7. I honestly do not recall what changes companies have done to their engines to accommodate for stop/start, but I refuse to believe that long-term wear and tear have not already been looked at. There might be some extra oil lines used or some other way to adjust for lube the system. I do know that typically these engines have larger starter motors to account for all the extra stop/starts. Stop/Start might be rather new to us here in the US, but its fairly common on European, and possibly even Japan cars for a few years now already.

        I don't think it's near as bad as a cold start where the oil galleries have had time to drain down. During a stop/start period, the oil galleries would still be mostly full of oil and the pump primed. I'd be surprised if it were more than a fraction of a second for the oil system to build pressure. Not to mention that residual oil on the wear surfaces would provide a short period of protection.

        you're only thinking cost. It's still annoying having to fill up all the time. And this doesn't hurt performance in any way.

      So, up to, what? 13 city/ 20 hwy/ 17 combined? I'm not sure why people get up-in-arms about this stuff. "Oh the rich don't care about fuel efficiency". That may or may not be the case, but that doesn't necessarily mean a company known for a 10mpg COMBINED rating (1999 Diablo), can't improve. It's not like they've had to dumb down the Lamborghini "experience" to get there. Stop living in the 70s

        Needless complication. It isn't a Prius.

          You're right, it's not a Prius. Because it's not a hybrid. Gov: "Hit your CAFE targets or pay penalties". Lambo engineers: we could easily do this with a simple stop-start system and a cylinder-deactivation. Hmm...doesn't seem so "needless" either.

          Cafe Schmafe, I doubt Lambo hits the targets either way and penalties just go to the customer.

      Why would you put that garbage in a car like this? If you spent $500,000 on a car that gets 11mpg, you literally don't give two craps about gas mileage. The car is probably only going to get driven maybe 1000 miles a year anyway, so who cares?

      Only stupid Lambo owners would say: "I love the car, but it gets really bad MPG..."

      I have to say it's pretty ridiculous reading all the angry comments from people that will never come close to owning an Aventador. What do you gain by getting all "rich people don't care about mpg!"? Not to mention the complete lack of understanding of the real issue. The owners don't give a **** but the government does. If Lamborghini and every other exotic manufacturer doesn't improve fleet mileage they won't be in business. That is the only reason they're doing this and will continue to do so. People need to use some brain power instead of getting all hot and bothered about what rich people care about, especially since it will never affect them.

        I agree. People have to stick their 2 cents into everything that does not have anything to do with them. People slam others that will never have anything to do with their lives. People always want to give their advice or input while some have to count their change to buy a coke.
