Yes ... How could anyone even make a case fo the PC engine being more efficient?
How many VW diesel cars have you had? I love VW's but don't see much reason to buy a diesel. I drove a new 2012 and was amazed at the power, smoothness and quiet. Been think'ing a lot about Passatt's lately. Golf is a gem too. Wife has Golf.
My Dad had a rabbit in the early 80's, PC diesel. I bought a beater 81 rabbit around 92, similar PC diesel. Ran the snot out of it and it would not die. Both would absolutely NOT start unless you gave them at least some glow.
I bought a jetta new in 2000, that one is direct injection. It does have glow plugs that extend into the cylinders, but don't really come in to play unless below about 20-30F. Then the dash shows a glow light and you are supposed to wait before cranking. Above that temp, just turn the key and go. Still have the car and it has been quite good.
The newer vw diesels have much more complex emission and injection control. And of course the cheat, too. Shame on them. But I do think they are close to having the emissions de-bugged to the point reliability will be acceptable. Sort of like cat converter gasser cars in the 70's. Horrible. Then de-bugged and now no one thinks a bit about them. I hope diesels get to that point too. Watching carefully.
Right now the economics don't really support buying a small diesel car. But I continue to drive one, and would like to replace it with another when the need arises. Why? Because I am a gear head and an engine engineer and the the diesel IS the better engine hands down, provided you can make it socialable and emission systems reliable. And I just like the way they run and drive.
My biggest gripe about the vw cheat was this: You frigging idiots have just screwed me out of being able to buy another stick shift diesel car.
