You're doing it wrong.
Turbos are on 75% of new cars sold in Europe

You don't have to be a scientist or an automotive engineer to look at the fuel economy that major automakers are squeezing out of their vehicles with normal combustion engines today and wonder if we really need EVs and hybrids. More than one diesel car in Europe is able to provide fuel economy as good or better than the hybrids people generally think are so fuel thrifty.
 
The catch is that we rarely see diesel engines in the US inside a car, that will be changing, but the diesel car isn't common today for American drivers. One thing that is becoming very common for fuel efficiency sake is the addition of a turbocharger to allow a smaller displacement engine to produce acceptable power to provide the performance drivers expect.
 
The turbocharger is something that was often thought of for performance cars like the Grand National Buick in the mid to late 1980's. Today the turbo is used in a number of engines including the very popular EcoBoost line from Ford. Ford's EcoBoost engine inside the F-150 truck is selling very well and has a towing capacity on par with normal engines with larger displacement. The turbocharger is even more widely used in Europe where Reuters reports that 75% of all new cars come with one.
 
Craig Balis from Honeywell Turbo Technologies told Reuters in an interview, "The turbocharger is a green technology in the sense that it's helping cut emissions and raise fuel economy. It's a critical component to get more fuel efficiency out of the engine."
 
"Emissions regulations in Europe, the United States and worldwide are a driving force for cleaner, greener vehicles and that's a great landscape for turbocharging," said Balis. "We're confident about the continued evolution of combustion engines and the growing role turbocharging has."
 
Reuters reports that a diesel engine that has a turbocharger can get 40% more mileage than one without a turbo and a gas engine can go 20% further per liter of fuel than one without a turbo. With the impressive economy that normal engines with turbochargers achieve there are many that wonder if we even need EVs and hybrids.
 
Pierre Gaudillat, policy officer at the Transport and Environment lobby group in Brussels, was asked if we need EVs from a CO2 point of view. He said, "That's a valid question. The answer is: maybe not. Turbos are a no-brainer for cutting CO2 because the efficiency gains are really quite significant. In the near term, we don't really need and can't count on electric vehicles to deliver the CO2 savings. Maybe not until about 2030 or 2050."

Enough with the prejudice already.

Diesel's have been in use for decades and not just on sports cars. Almost anything with a Diesel in Europe comes with one or more Turbos and that includes cab's and big trucks as well. I've seen cars with turbos happily drive the distance of the moon and back with no major work done on them. Plus it's not like a turbo is a super expensive high tech gizmo the patent goes back to 1905 and it has been widely used since about 1920.

A big V8 can be fun but why drag all that weight around for normal driving. You may get decent mileage while cruising but in town with all the starting and stopping something light is better.

What about your prejudice? It's apparent right away....

It depends where you live. Maybe he lives out in the country and has a 30 minute highway commute (like I do). My BMW 545i with it's 4.4L V8 is great. I get 27 to 28 MPG on my work commute. That's really all the driving I do, and I'm usually doing 80 MPH. I know of little 4 cylinder cars that can't get much better than 22 MPG. In fact, I had a VW R32 that was a NA 3.2L V6 and it was only getting 22 MPG. The big BMW was an upgrade looking at it from that view....

I really don't think I'll enjoy EV's at all, given where I live and the fact that I enjoy the larger cars.

sorry to let you know your vw r32 was a heavy car, the bmw is a barge. You sounded uninformed when you said, ("I know of little 4 cylinder cars that can't get much better than 22 MPG".) Often a car will develop problems that ruin fuel economy, no matter what amount of cylinders. I hope you will do more research before buying your next vehicle.

I think you're missing the real point here, which is that different people have different needs. Someone who's happy with their V8 isn't going to be interested in a buzzy, high-strung turbo 4 cyl or a slow-revving, heavy diesel.

The fact is, V8 engines remain available because many of us consider them ideal for our needs. And big car technology has also come a long way. Check out Chrysler's hemi-powered 300 with the 8 speed ZF trans that manages 29 mpg highway. To those of us who live in rural areas and must endure long commutes, that's a very attractive proposition.

Everyone has a different braking/accelerations/hills in their route, but if you want to compare apples to apples, the 545i can only get 23MPG on the EPA highway test.

It's a 333hp engine, so a close comparison would be BMW's 3.0L twin turbo (300hp) found in the 535i. It gets 26 MPG in the same test.
