So the new Impalla that chevy has released has a option for a 330 HP V8 with 28 highway fuel consumption.

Thats amazing. Just amazing. I wonder how far fuel efficency can be pushed?

...That’s because only four of the eight cylinders are activated during some driving conditions to increase your fuel economy – up to an estimated MPG 28 highway.1 When you need full power, the other four cylinders are reactivated.

I know another car had this feature before... I forget which one. I'm pretty sure it was German. I'm thinking Mercedes? (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif)
