  • Mercedes-Benz S 400 Hybrid

    We talk quite a lot about how global regulations aimed at improving fuel efficiency and reducing carbon emissions will lead to much smaller, more powerful engines. Latest case in point? Would you believe a four-cylinder Mercedes-Benz S-Class? Just to be clear, this is the big Benz. The one beloved of burgermeisters for half a century, the symbol that you've arrived, that you can afford--and deserve--the biggest Mercedes-Benz sedan they make. Four cylinders? Really? Yup. The 2011 Mercedes-Benz S 250 CDI uses a 204-horsepower 2.2-liter turbocharged four-cylinder diesel engine. It's the first...

    53-MPG Clean-Diesel Audi A4 TDI Coming To U.S...In Four Years

    German automakers have spent time and money on ad campaigns promoting clean diesels as the better way to improve fuel economy, so far with limited results. But that could change when Audi brings a TDI diesel version of its best-selling A4 model to the U.S. So far, its only TDI offerings are the Q7...

    Audi To Add Diesel Versions Of Every Model It Makes By 2015

    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...

    Clean-Diesel Mini? Green! A 3500-HP Diesel Mini? NOT Green!

     We've written before about the diesel-engined Mini Cooper D that's sold in Europe, but not in the U.S. We really like the idea of a clean-diesel Mini. And now for something completely different. How about a 3500-horsepower V-18 diesel Mini? Ummmm, yes. At this week's Goodwood Festival of Speed...

    BMW To Add Diesel 5-Series & Another Model, Maybe Diesel Four?

    The list of cars offered to U.S. buyers in gasoline, diesel, and hybrid models is going to get longer. On the heels of its confirmation that the 2012 BMW 5-Series will be offered with a full hybrid system, the company has also confirmed it'll sell a clean diesel version of the new 5-Series in the...

    Carbon Cop Cars To Go Green With BMW Clean Diesel Engines

    Many European countries use BMW sedans as patrol and pursuit cars. Now, BMW says it will sell more than 240,000 engines to U.S. police-car startup Carbon Motors for that company's cruiser. The big shock? They're diesel engines. Specifically, BMW's 3.0-liter twin-turbo straight-six clean diesel, as...

  • 2010 Mazda CX-7 i Sport

    Mazda's always had cool technology. They're the only carmaker that's steadily developed the compact, high-output Wankel rotary engine, for instance. And they're known for powerful, high-revving piston engines and slick-shifting gearboxes. Then there's the green side of the brand, which already sells mostly small and relatively fuel-efficient cars. Not only will U.S. buyers get the 2011 Mazda Mazda2 subcompact soon, but the company is evaluating whether to offer its iStop start-stop system on some U.S. models. What's so cool about iStop? Well, unlike so-called micro-hybrid systems--which...

    Audi's Green Onslaught: A3 Sedan, A8 Hybrid, e-Tron Tesla-Fighter

    It's going to take Audi a long time to live down its U.S. chief's infamous quote that anyone who buys a Chevrolet Volt extended-range electric vehicle is an "idiot." But after sticking to diesel for a long time as its sole green strategy, Audi is now storming ahead into smaller, hybrid, and...

    Green Car Sales: Winners and Losers of 2009

    It's beginning to look as if the worst is over for U.S. auto sales. The year that just closed was, in the immortal words of Queen Elizabeth II, an annus horribilis, with only 10.4 million vehicles sold, down 21 percent on 2008 and the lowest total since 1982. But some light seems to be appearing on...

    Why Can't We Buy Small European Diesels in the U.S.?

    It may be the one question we hear most often here at GreenCarReports.com: Why can't I buy one of those great little fuel-efficient diesels, like they have in Europe? Take, for example, the ultra-high-mileage Econetic version of the Ford Fiesta, sold in Europe with a 1.6-liter turbodiesel that...

  • 2010 Volkswagen Golf TDI

    We seem to be covering the 2010 Volkswagen Golf TDI clean diesel hatchback an awful lot here, but a recent blog post raised an issue we hadn't considered: How far can the 2010 Golf TDI go on a single tankful of diesel fuel? The question comes from blogger, host of #carchat on Twitter, and general all-around car personality Michael Banovsky. In reviewing the new 2010 Golf TDI for Canadian and U.S. outlets, he stumbled when calculating maximum range, because the two countries' fuel economy rankings differ. A lot. Does Canadian diesel go further? After doing the math to match gallons and liters...

    Driven: 2010 Volkswagen Golf TDI, Clean Green Diesel Hatchback

    As regular readers no doubt recall, we [heart] the 2010 Volkswagen Golf TDI. We think it'll be the big diesel winner in the U.S. market, and that's before we've even driven one. But Bengt Halvorson loved his drive in a European version of the 2010 Golf TDI. Now, our colleague Marty Padgett has...

    The 62-MPG 2010 Volkswagen Golf TDI We Won't Get In the U.S.

    While we think that the clean diesel 2010 Volkswagen Golf TDI will do well in the States, VW has just rolled out an uber-economical BlueMotion model for European markets that gets 62 miles per gallon of diesel fuel. BlueMotion is VW's designation for the most fuel efficient model in each of its...

    OMG: Gas Mileage Is More Important Than Cupholders, Say Buyers

    Car sales may have plunged to their lowest per-capita level in decades, but for the green-minded among us, there's some good news: Fuel economy is now more important to car buyers than are cupholders. That's one piece of data gleaned from a lengthy survey of car buyers by the big accounting firm...

  • Controlled Power Technologies electric supercharger

    In the accelerating quest for greater fuel efficiency, boosting engines--with turbos or superchargers--is one way to pull more power out of a given displacement. Traditionally, superchargers have been driven by chain or belt powered from an engine's crankshaft. Now, a British engineering firm has introduced the world's first electrically driven supercharger for volume production. It says its new system can improve the fuel efficiency of gasoline engines to the point that they're competitive with diesels of the same power output. For gas, diesel, even turbo engines The firm, Controlled Power...

    Clean Diesels Cost More, But Will Americans Pay For Them?

    It's well known in the car industry that a diesel engine costs 10 to 20 percent more to build than a gasoline motor of equivalent output. That's because diesels have to be sturdier, and these days all US-bound diesels are fitted with turbochargers to boost their power. Now a European executive has...

    Hybrid vs diesel: It's a longstanding green-car conundrum. Which is better, a hybrid-electric vehicle that recaptures wasted energy in a battery and uses it to assist the gasoline engine, or an efficient modern clean diesel that goes further on a gallon of fuel? The answer depends in part on your...

    Fast Forward: Mercedes-Benz Updates 1992 Diesel

    Now, this is cool. You've likely seen the Mercedes-Benz diesels of the 1980s and 1990s chugging along somewhere or other. But how much better are today's clean diesels than the solid old oil-burners of 20 years ago that still power those sturdy survivors? Back to the future: 1992 to 2009...
