Right.... so like I was saying, there must be a different explanation for how BMW is able to provide solid fuel economy from its engine without sapping its pep than using an 8-speed auto tranny.
The wife has a 2012 Elantra Limited, and I drive a 328i. While the Elantra bost a few more amenities and averages 34 mpg, the BMW, is a far superior car. Acceleration, braking, handling fit and finish with an average of 29-30 mpg.
We are now considering a 5 series or x5 for her. Until you've driven a BMW, you truly cannot compare.
Um, still not following your point...34MPG highway for a 2 liter turbocharger 4 cylinder sedan is not particularly impressive with a 6sp manual. Nissan is getting 37mpg highway in the new 4cyl Altima with a CVT.
Key term is CVT. What the difference in output between the two engines?

The Kia Optima turbo has the more horsepower and does 34mpg on the highway with an automatic transmission on regular gas. I'm not saying the BMW's fuel economy is bad, just nothing special for a 4-cylinder sedan. Even a 4100lb V6 Dodge Charger will do 31mpg on the highway with an 8sp auto.
So does the 330d have a single turbo, or no turbo at all??
Single turbo, all the diesel engines are turbocharged.
The absolute pinnacle of BMW's diesel engines though, I would argue is the 2.0L inline-4 used in the 320id, 170hp, which is easily upped to over 200hp with simple programming, and over 400nm/tq, which again, can be significantly raised, all while getting 60+ mpg highway at a steady 70mph.

For that price can't you get an Lexus IS350 with 306HP ?
It's not all about HP because that Lexus IS350 will destroy most cars with more 'advertised' power at the "crank"
