    The Mazda 2.0-liter Sky-D clean-diesel engine, when it makes its debut in a year or two, will almost certainly be the cleanest of the lot.

    More Volkswagen Diesel Woes: Feds Investigate 2011 Jetta TDI

    Volkswagen's TDI diesel engines have long attracted fans and repeat buyers. But now a second investigation this year into the reliability of its TDI engines may cast a shadow over its newest fuel-efficient clean-diesel vehicles. The National Highway Traffic Safety Administration last week launched...

    Reader Q: All-Wheel Drive Hybrid Or Diesel Cars (Not Trucks)?

    We get some of our most interesting topics from reader questions. Past questions include how emergency responders should react to hybrid and electric cars, and whether towing a Prius behind a motorhome is a good idea. Today, we have a query about green cars (not trucks) that offer all-wheel drive...

    2012 Audi A6 To Offer High-MPG Hybrid, Clean-Diesel Models

    Despite lack of an official confirmation from Audi of America, we'd bet significant money on the arrival of the Audi A6 Hybrid in the U.S. market. Why? Because the U.S. has the highest hybrid penetration of any market in the world except Japan, and "hybrid" means "high gas mileage" to a large...

    How To Send Hybrid Cars From Japan? Diesel-Hybrid Cargo Ship, Of Course

    In this day and age, when it comes to being green, looking at the end result is never enough. You have to take a life cycle approach to assessing how green something is, which in the case of cars, means looking at how they are manufactured and delivered to your driveway. Unfortunately, most cars...

    Adding Urea To Clean Diesel Cars: Can I Just Pee In The Tank?

    We get punchy around High Gear Media occasionally, and sometimes we BS back and forth about topics less salubrious than, say, fuel efficiency and lowering our oil dependency. Which is how the following question came up: If the urea runs low in my new clean-diesel car, can I just pee in the tank to...

  • 2010 Audi A3 TDI

    Diesel models may account for more than half of all new car sales in Europe but in the U.S. their numbers still hover around just 3 percent of the market. This in part because of a national memory of the noisy and polluting diesels of three decades ago, and in part because diesel fuel and engines are still too expensive to make good business sense. This latter issue is something we’ve touched on several times before here at GreenCarReports, but thankfully, the tide is starting to turn. One of the biggest suppliers of diesel technology to the automotive industry is Bosch, which is...

    Could China’s Hawtai Supply Saab With High-MPG Clean Diesels?

    Saab's new deal with a fledgling Chinese automaker doesn't just mean a lifeline for the struggling Swedish automaker; it could over the longer term become a much-needed powertrain supplier—especially in the area of clean diesels. Through the deal that's almost finalized, Hawtai Motor Group...

    2011 Miles In A 2011 VW Jetta TDI: A Not So Quick Drive

    In some new cars, you can't learn enough over the course of a first drive. There's not enough time to experience every handling nuance, or every electronic helper, in a hundred miles or less. With the 2011 Volkswagen Jetta TDI, you'll find the opposite. Spending more than 2000 miles behind the...

    Attention, Shoppers: Infiniti QX56s, Diesels Are NOT Hybrids

    It will come as a horrible shock to the driver of the pale green Infiniti QX56, but the 2-ton-plus full-size sport utility vehicle is not actually a hybrid. Nor, for that matter, is a Volkswagen Passat TDI--though it at least has a diesel engine, which gives higher gas mileage than the QX56's...

    Ford Still Bearish On Diesels, Product Chief Derrick Kuzak Explains Why

    It’s the age-old question: Why do we still not have the wide range of clean-diesel models that automakers have offered to the rest of the world for decades? It’s proven that diesel powered cars can offer hybrid-like fuel economy--even better in some situations--as well as thrilling...

  • 2010 Audi A3 TDI

    While Volkswagen and Mercedes-Benz are the long-term diesel stalwarts in the States, relative newcomer Audi has ambitious plans. During a lengthy teleconference yesterday, Audi confirmed that it would add TDI clean-diesel models to every car it offers in the U.S. market by 2015. Audi has frequently touted the strong sales of its two current TDI models, the 2011 Audi Q7 TDI large sport utility vehicle and the compact (but aging) Audi A3 TDI hatchback. The A3 TDI is by far the more affordable of Audi's first U.S. diesels, and the company scored a coup when it was named Green Car of the Year for...

  • Audi A3 TDI clean diesel - European model

    In Europe, roughly half of all passenger cars sold come with fuel-efficient diesel engines. But for a variety of reasons, passenger diesels haven't caught on in the States, though the number is climbing slowly. Audi, proud of its diesel engine technology--which, among other things, has won the prestrigious 24 Heures du Mans endurance race in the Audi R15 TDI--is forging ahead and plans to offer a diesel variant of every model it sells in the U.S. by 2015. Modern clean diesels usually deliver fuel economy one-third to one-fifth better than that of a gasoline engine of similar power. They're...
