If they export 50K diesel Cruze cars to Asia, this allows them to sell a few thousand here to people like you without creating financial losses. However make no mistake, this change in marketing strategy does not mean demand for domestic diesel passenger cars is growing sharply or this is some fix for eco problems...
Well, I wouldn't go that far. Diesel does contain about 10% more BTUs than gasoline per unit, and diesel engines have an energy conversion efficiency of around 30% compared to only 20% for gasoline. So diesel does have some real "eco" advantage. The trouble is the engines are more expensive to produce, forcing the car makers to charge more for them, and diesel fuel is more expensive. Once those two obstacles are overcome in North America, diesel may provide a lower cost of ownership to car owners. But it ain't nowhere near there yet.
TTAC said yesterday it would take 115 years for the Cruze diesel to pay itself back compared to a 1.4T equipped car.
