In order to meet CAFE gas mileage standards manufacturers are experimenting with new technologies such as cylinder deactivation and turbocharging. In addition both are getting direct injection.
It’s interesting that cylinder deactivation and turbcharging are almost opposite. In one, you take a powerful engine and deactivate some cylinders to make it a weaker but more fuel efficient engine, and in the other you take a fuel efficient but weak engine and make it powerful. The Ford F-150 with the 3.5 twin turbo is one example and the GM 6.2 liter with the AFM system is another.
What is your opinion on the technology and which system would you rather own.
