Guess they were just trying to make it about equal to the gasser. Extra torque is just the by-product of a turbo.
why do a turbo if they just want to make it equal to the normal version? they sell the non-aspirated and turbo version over there, so they must have a reason for offering it.Twist2Stop said:Guess they were just trying to make it about equal to the gasser.

The longer-stroke of the engine may be the primary reason why there is less horsepower, as it reduces the rate at which the engine does work. However, the long stroke of diesel engines typically also aids in the engine's ability to generate more torque....diesel engines have more torque output than their gasoline engine counterparts thanks to the longer stroke and the high energy content of diesel fuel
Because a non-turbo diesel is about as much fun as a stick in your eye.sticksandstones said:but then why turbo? im genuinely asking because I dont know much about car mechanics
This. While diesel engines have great torque, a turbocharger is almost a necessity for any decent top-end acceleration (and they help with efficiency).Thelosis said:Because a non-turbo diesel is about as much fun as a stick in your eye.sticksandstones said:but then why turbo? im genuinely asking because I dont know much about car mechanics
Subaru hasn't been doing diesel engines for very long. Heck, supposedly, Subaru is the first manufacturer to implement the boxer-engine layout to a passenger production car in a diesel-engined form.Twist2Stop said:How long has Subaru been doing diesels?
Any idea why that is?Twist2Stop said:I have noticed a lot of extraneous crap under the hood when companies try to go diesel for the first time.
Are you referring to the plastic covering? That's most likely excessive sound deadening. I don't think Subaru's BOXER Diesel resorted to that route, but it still does have the top-mount intercooler (TMIC) like the gasoline-powered turbocharged Subaru engines.Twist2Stop said:I have noticed a lot of extraneous crap under the hood when companies try to go diesel for the first time.
ECU (computer controlled) direct injection and urea exhaust injection. Exhaust byproduct is then CO and water.ClubCrosstrek said:Isn't it something about them not being able to meet California's stricter emissions laws? If so, how do other manufacturers get away with it?
Very valid point. I guess it's not so much the diesel I care about as it is the turbo.CJBROWN said:ECU (computer controlled) direct injection and urea exhaust injection.

I doubt you'll see the diesel come over. So far Mercedes Benz is more than four years coming out with their small diesel for C-class and GLK. It's going to be a premium price point which negates some of the fuel economy savings. MB has vastly more resources than subaru and have been at the diesel game for a hundred years.
Would you pay $32K for a basic Crosstrek with a diesel motor? Fuel savings payback can run many years. I don't know about you but I trade off every 2-3 years. I get sick of driving them and want something new.
