Diesels

  • 2012 Jeep Grand Cherokee

    Chrysler will soon sell a diesel-powered Jeep Grand Cherokee, which may be followed by a diesel-powered Dodge Durango. The next Ram Dakota will get a diesel, too, but don't expect to see one in a Chrysler automobile.

    Jeep Grand Cherokee Diesel Sport Utility Coming In 2013

    The Jeep Grand Cherokee is one of the brightest stars among the cars that propelled Chrysler--now controlled by Fiat--to a 26-percent sales increase in 2011, raising its share of the U.S. market 1.3 points to 10.7 percent. Yesterday, the company said it would start building a diesel version of the...

    Porsche Cayenne Diesel To Arrive In U.S. Second Half Of 2012

    Hybrids, electrics, and various permutations in between get a lot of the attention when it comes to greener driving, but the dino-burning diesel deserves its place in the pantheon as well, at least for the time being. Porsche agrees--at least in the case of the Cayenne. The diesel version may be...

    Jaguar XF Clean Diesel Completes U.S. Cross-Country Tour

    One week ago we brought you news of British brothers David and Alexander Madgwick, who'd set out on a tour across North America at the wheel of a Jaguar XF diesel. 2,884 miles later, they've made it from New York to Los Angeles in the most efficient model Jaguar has ever produced. The economy over...

    Jaguar XF Clean Diesel Sets Off On U.S. Tour

    In an effort to meet future fuel economy requirements, more manufacturers than ever are considering selling diesel models in North America. The next carmaker considering diesel sales could well be British sports and luxury car maker Jaguar. According to Motor Authority, a British-registered...

    2012 Mercedes-Benz S 350 Bluetec Clean Diesel: Quick Drive

    What can you say about driving a Mercedes-Benz S-Class? It's luxurious, smooth, powerful, packed with features, impressive on the road, and very, very large. Now you can add another adjective: green. While the S 400 Hybrid has been in the mix for two years, Mercedes-Benz is launching a clean-diesel...

  • 2011 Volkswagen Golf TDI

    The Volkswagen Group 2.0-liter clean-diesel TDI engine has been fitted to quite a number of VW vehicles over the years, as well as the Audi A3 TDI. Now the company has announced a voluntary safety recall that applies to both Golf TDI models built from May 2009 to September 2011, and the more numerous Jetta TDI and Jetta SportWagen TDI models built between May 2008 and September 2011. Volkswagen has also temporarily pulled its Jetta TDI and Golf TDI models off sale until new vehicles at dealers can be inspected and repaired if necessary. The 2012 Volkswagen Passat TDI, however, uses a somewhat...

    Homebrew 6-HP Motorcycle Sets Biodiesel World Speed Record

    Combine a whole bunch of parts from motorcycles, go-karts, industrial machinery, and even generators, and what do you get? In John Petsche's case, he not only built a motorcycle that runs on store-bought vegetable oil, he managed to take home a world speed record for the 350cc Alternate Fuel class...

    2009 BMW X5 Diesel Recalled For Faulty Fuel-Filter Heater

    Clean-diesel vehicles, a slowly growing segment of the market, unquestionably return higher fuel economy figures than their gasoline-engined counterparts. But they have their own set of issues, too, including recalls specific to some of the diesel engine components. The NHTSA has issued a recall...

  • 2011 Ford F-250 SuperDuty pickup truck Land Speed Record contender, Bonneville Salt Flats, Utah
    Diesel Land Speed Record: 171 MPH In A Ford F-250 Pickup!

    There are lots of different Land Speed Record categories, and each year one or two of them fall to new challengers. So it's not surprising that new records for production diesel and biodiesel trucks were set this weekend at the Bonneville Salt Flats in Utah. What is surprising is the vehicle that...

    Outdated Tests Skew CAFE Gas Mileage Ratings: 48-MPH Freeways?

    It's widely accepted in the auto industry that all manufacturers game the test cycles used to establish emissions and gas-mileage ratings. Ask auto engineers about the topic, and they tend to get a faraway look and go silent. But the test cycles established in 1978 and used ever since are far from...

    Bentley To Fall In Line, Add Hybrids, Diesels To Its Lineup?

    A powerful diesel engine like the Volkswagen Group's V-12 TDI unit will be perfect for a stately and luxurious SUV from Bentley.

  • Chevrolet Beat Diesel (aka Chevy Spark) brochure image from India, Aug 2011

    It must be the Chevrolet Spark minicar's moment in the sun. Last week, GM confirmed that the smallest Chevy ever sold will come to the U.S. as a 2013 model. Then we put two and two together to wonder if Chevy's first all-electric car might be a converted Spark. What we forgot to mention--until now--is that two weeks ago, Chevy launched the Spark in India (where it's known as the Beat) with a tiny three-cylinder turbodiesel engine displacing less than a liter. Diesels are more and more popular in India for their extremely high fuel economy, and this one is rated (on the Indian test cycle) at a...

    A 2011 Volkswagen Touareg, piloted by a trio of German drivers, set a new world record for traversing the length of the Pan-American highway.

    Mazda Next-Gen Sky-D Diesel: Cleaner Than VW TDI?

    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...

  • Auriga Leader hybrid cargo ship

    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 produced overseas, including top selling hybrids like the Toyota Prius, are shipped over on huge cargo ships, the kind that produces as much air pollution as roughly 50 million individual cars. While automakers have little choice towards alleviating this issue, it’s good to see that Toyota, at...

    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...

    Bosch Predicts Diesel Sales To Reach 10 Percent Of U.S. Market By 2015

    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...

    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...
