With an increasing number of diesel passenger cars appearing in showrooms, car buyers have more options for fuel-efficient driving than they did only a few years ago.

After a brief hiatus several years ago, when new and tougher emissions standards came into effect for diesel vehicles, the number has steadily increased--and 2014 has a bumper crop of new diesel vehicles.

Two of the most important are the 2014 Chevrolet Cruze Diesel and the 2014 Jeep Grand Cherokee EcoDiesel, both of which add a diesel engine to an already popular vehicle sold in high volumes.

We've already covered every diesel car on sale in the U.S., but here's our guide to the debutantes among the group.

2013 Audi A8 TDI

This is Audi's year to expand its array of diesel vehicles, previously confined to the expensive and aging Q7 TDI large sport-utility vehicle.

For 2014, the company has added the Audi A6 TDI mid-size sedan, A7 "four-door coupe," and A8 TDI large luxury sedan, as well as a Q5 TDI compact crossover.

The three sedans all use a 3.0-liter V-6 turbodiesel, which puts out 240 horsepower and a substantial 406 pounds-feet of torque.

The mid-size A6 TDI gets a 29-mpg rating, with a starting price of $57,500.

The sleek, stylish A7 TDI comes in at the same 29 mpg combined, but adds an extra $9,400 to the starting price--making it your call if you want the extra $10K of style in your German luxury diesel sport sedan.

The large aluminum-bodied 2014 Audi A8 TDI is rated at 28 mpg combined by the EPA, and starts at $82,500.

Then there's the Q5 TDI crossover, which also uses the V-6 engine, and is rated at 27 mpg combined (24 mpg city, 31 mpg highway) at a starting price of $46,500.

For the record, that's $4,400 lower than the all-but-invisible Audi Q5 Hybrid, a rare beast indeed on U.S. roads.

All four of the new 2014 Audi diesels will be arriving in showrooms this summer.

This year marks the return of the BMW 328d, the diesel-engined version of BMW's 3-Series sport sedan--along with a new Sports Wagon model to sit alongside the four-door sedan.

The latest model for 2014, however, uses a 180-horsepower 2.0-liter four-cylinder turbodiesel that puts out 280 lb-ft of torque rather than the more powerful but thirstier straight-six turbodiesel in the previous generation of 335d 328d 3-Series diesel.

It powers the rear wheels through an eight-speed automatic transmission, and the combination is rated at 37 mpg combined, made up of a city rating of 32 mpg and a high 45-mpg rating in the EPA's highway cycle.

Add the xDrive all-wheel drive option, and those ratings fall slightly, to 35 mpg combined (31 mpg city, 43 mpg highway).

The first diesel 3-Series cars for 2014 will arrive at BMW dealers later this fall. The base 328d sedan with rear-wheel drive starts at $39,525; the xDrive sedan adds another $2,000 to that; and the Sports Wagon (only offered with xDrive) is priced from $43,875.

The 2014 Chevrolet Cruze Diesel is Chevy's first diesel passenger car in 28 years, and it's a bit of an experiment for the carmaker.

It's fitted with a 151-horsepower 2.0-liter turbodiesel four-cylinder engine, built in Germany and adapted from one that's the larger of two Cruze diesel options in Europe, where diesels take roughly half the total new-car market.

That engine powers the wheels through a six-speed automatic built by Aisin, and slightly tougher than the six-speed automatic used on all gasoline-engine Cruzes sold in the U.S.

The list price starts at $25,695, near the top of the Cruze range, but Chevy hopes the diesel Cruze will attract new buyers to the brand who might not otherwise have considered a Chevrolet compact sedan.

The EPA rates the Cruze Diesel at 33 mpg combined (27 mpg city, 46 mpg highway).

  1. Explain to me please, how this technology, which is neither new nor expensive, should be sold at a premium by Automakers? Shouldn't there be a shift away from gasoline ICEs to diesel or natural gas? And shouldn't those cars be more attractive to buy because of immediate savings, not those which can be realized in 3-5 years? Heck, with immediate fuel savings, one might turnover a car in 2 years which would benefit the automakers.

    I just think these grand old manufacturers are senile in their sales and marketing strategy, and is another reason I own a Tesla Model S.

  2. @David: The diesel engine itself is not new, but the complex and expensive aftertreatment (including urea injection) to enable diesels to meet current North American emissions standards is new--and quite expensive.

    Automakers say that a diesel engine is about 15 percent more expensive to manufacture than a gasoline engine of the same output, largely due to its having to be stronger to withstand higher compression ratios. Then there's the aftertreatment and associated plumbing that have to be built into the vehicles.

    THAT'S why diesel models are more expensive.

  3. I doubt these regulations matter on diesel generators do they..? They seem to always be dirty and pretty cheap, starting at around a thousand and putting out much more power than a gas generator…

  4. Besides aftertreatment (which gasoline engines also have...catalysts...although not as costly as the urea and particulate filters on diesels) they generally require larger & heavier components due to their high compression ratios, and more sophisticated fuel systems since power delivery isn't throttle controlled, rather fuel rate controlled. Materials and sophisticated components do cost something.

  5. @ John,

    Just to clarify, the previous (six cylinder) diesel version of the BMW 3 series was the 335d, not 328d. 328d is a new designation with the introduction of this model (even Europe doesn't have a 328d).

    I know because I have a 2010 335d. ;)

  6. @Loren: Entirely right, and thanks for pointing that out. I've edited the article accordingly. Brain fade while writing!

  7. if they could find a way to make use of the 80% wasted energy in the form of heat which is pertinent to all ICEs of any kind then i would probably give it a good looksie but otherwise, no thanks, electric trumps ICE as it currently stands.

  8. You completely missed the new 2015 Mazda6 diesel that will be here next year.

  9. @Steve Note that the title of the article says "2014". We'll cover the 2015 Mazda 6 diesel, assuming it arrives, when we do a similar roundup of 2015 models.
