heres 2 cents from a stupid fuck

Basically: the third world clamoring for American living standards (which are vanishing in America), "fuel scarcity", and environmentalist bullshit.
I have news for this moron: turbochargers marginally increase fuel efficiency relative to the power from a comparable n/a engine. Look at Ford's Ecotech bullshit. Their twin-turbo v6 model doesn't get any better gas mileage than the 5.0 V8. The Focus's turbo 4 cylinder gets about 24 mpg combined, which is pathetic.
The turbo is a fraud. I suspect manufacturers are rather using the subterfuge of "global warming" as an excuse to further ram down unit costs. No one notices because in the middle is a Sacred Cow, "the environment". Its cheaper to produce smaller engines with the same technology and then slap a turbo on top so no one notices.
I wouldn't be surprised is fuel is saved by going from 10 cylinders to a turbo 6, but within the context of the big bitch about fuel and environment the consequences are marginal considering that this is a **sport**
but the retard who wrote the above article probably speaks for the average idiot because he doesn't even go that in depth. Its just: well we need it, because current year! Literally, the dumbass says "we've been doing n/a for too long, CURRENT YEAR"
