Popular Mechanics; The Case for Diesel: Clean, Efficient, Fast Cars (Hybrids Beware!)

I stumbed across a good article via AutoblogGreen for 12.28.07 about "Hybrids, beware of diesels". I find this interesting since Honda has been really bringing the developement of 'clean diesel' engines to the forefront. Here's a link to a previous post of mine;

Here are some highlights of the article;
-Most Americans have a bad impression of diesel cars. We think of them as loud, hard to start and foul-smelling. We sneer at them for lacking the get-up-and-go of their gasoline-powered cousins. And we dislike them for their perceived environmental sins, chiefly the polluting brew of sulfur and nitrogen compounds that they emit into the atmosphere. All those complaints were fair a generation ago.
-Today, diesel powertrains are on the map again, for both car manufacturers and efficiency-minded drivers. The technology could be here to stay, even if fuel prices (improbably) decline. The new cars run as well as their gasoline-powered competitors. And as for the emissions problems of the past�well, the dirty bird of fossil fuels isn�t so dirty anymore.
-The fuel contains more energy per unit volume than gasoline, and diesel engines operate at higher compression ratios than gasoline engines�typically 14:1 to 25:1, compared to 8:1 to 12:1. (The compression ratio is the relationship between the volume of the cylinder when the piston is at the bottom of its stroke and the volume when it�s at the top.) The higher the compression ratio, the more mechanical energy an engine can squeeze from its fuel/air mixture. So each time the mixture in a diesel engine�s cylinder ignites, the car gets a slightly bigger push than it would in a gasoline engine. That means it takes less fuel to move the car down the road. It also means that the engine generates a lot of power even when it isn�t cycling fast�and that�s the source of the beefy low-end torque these vehicles are famous for.
- A recent study by J.D. Power and Associates found that in 2007, 23 percent of U.S. car buyers were considering a clean diesel for their next purchase, up from 12 percent the year before.
-�This is going to be remembered as the decade when we transformed diesel.�

The Coming Diesel Invasion
AUDI A4 SEDAN
Engine: 3.0-liter V6 Target Release Date: 2008This 240-hp turbocharged direct-injected engine will also be available in the full-size Audi Q7 sport utility.
BMW 3 SERIES SEDAN
Engine: 3.0-liter twin-turbo inline Six Target Release Date: 2008BMW plans to release this 3.0-liter in 5 and 6 Series models in 2008 as well. It reportedly gets more than 35 mpg.
CADILLAC CTS SEDAN
Engine: 2.9-liter TDI V6 Target Release Date: 2009Look for clean diesel also in the Buick Enclave, GMC Acadia and GM light-duty pickups, around 2010.
FORD F-150 PICKUP
Engine: 4.4-liter V8 Target Release Date: 2009Derived from the Euro-spec 3.6-liter currently used in Land Rovers, which get around 31 mpg on the highway.
HONDA ACCORD SEDAN
Engine: 2.2-liter i-DTEC Target Release Date: 2009The British version gets 51.4 mpg in combined city/highway driving. The hybrid Civic gets 50 mpg.
SATURN AURA SEDAN
Engine: To be determined Target Release Date: 2010The Aura�s Euro twin, the Opel Vectra, gets more TDI options in �09, which will transfer to the model coming here.
