Have you guys noticed that almost ever car manufacture is coming out with turbos now in their vehicles. I think in 5-10 years, almost every car will have some type of forced induction on it. You can make more power with a turbo, on a smaller engine, and still get great fuel economy.

 

Wait till they start making turbo diesels with three times the torque as a gas engine ... we're all going to be driving smokers :-)

 

They're going to be integrated into the "green" movement. I predict just about every hybrid will have them in the next decade.

 

A smaller engine with a turbocharger will have operating in a region of lower brake-specific fuel consumption than its NA equivalent.

 

That's what the OE's want you to believe^^. Bottom line is power is power. whether its a 2.0L Turbocharged engine making 300bhp or a 3.0L N/A V6 making 300bhp they are going to use about the same amount of fuel at peak power. Oftentimes the turbo engine will require more fuel due to the increased combustion temps. About the only time you will see greater efficiency in the smaller engine is when its off boost and how many times is that gonna happen? lol

 

^ you drive in off boost like 95% of the time unless you want to ram the car in front of you

Id rather have the 300hp v6 with the deisel truck turbo.

 

What yellow01 said.



Apart from during a drag race, you have far less frictional and pumping losses, and greater VE to boot. The smaller engine tends to require larger throttle openings, which can be done electronically without the driver knowing. Not only that, but you are actually recapturing exhaust energy and putting it to work, instead of just making noise and heat.

 

Ford Australia has just released a 2.0l turbo four-cylinder engine in our Falcon they call EcoBoost in what is traditionally been renowned for both six-cylinder and V8 engines ? I wonder if the weight factor will be an issue.
