Lamborghini Pledges Carbon-Neutral Production By 2015 - Gas 2
This should be interesting to watch.
Lambo are already in a good position as far as the "green" bullshit goes. A couple of years back the EU brought in a law stating that the average emissions of a manufacturer's vehicle range had to be below a certain amount. Awesome for makers like Lambo (who are of course owned by the VAG mega-group) and Fiat owned Ferrari, not so good for stand alone makers like Aston Martin, hence the god-awful Cygnet that's just a Toyota IQ with a bad Aston-brand facelift.
The other benefit is that Lambo have the massive resources of VAG to call on for funding the improvement, but also doing the development as well. Getting greener is a damn sight easier when your parent company has already spent the money on the labs and had great success with low emission/high MPG cars too.
At the end of the day, as long as the cars remain amazing to look at, fast as fuck, intoxicating to drive and retain an exhaust note to stir the soul I personally couldn't give a flying fuck what powers them or how much fuel they use. Though a thumping great V12 is always going to be desirable in a supercar...
