  • Volkswagen XL1 Concept

    If the 20th Century was all about improvements in safety and performance for the motor car, the 21st Century see these criteria joined by efficiency.

    Ford Adding Start-Stop To U.S. Fleet In 2012

    Europe is already knee-deep in start-stop technology, but we Yanks haven't been invited to that party yet. Why? Because of differences in the way the U.S. tests fuel economy, for the most part. Without a real numbers difference to sell the feature, it's hard to justify the added cost. Ford...

  • GM, Purdue University Working On Thermoelectric Energy Regeneration

    Thermoelectric energy regeneration sounds like a complicated topic, but it's really pretty straightforward: recapturing energy that would otherwise be wasted as heat and using it to power something.

  • fiat multiair powertrain technology 003

    Getting more out of the current generation of hardware is becoming increasingly important for the major carmakers as fuel and emissions standards tighten, but getting more power out of smaller, less expensive engines is also advantageous from a cost perspective. That's what makes Fiat's Multiair technology so attractive, and explains why Chrysler might get the technology in the very near future. It's actually surprisingly easy to retrofit the Multiair valve system to an existing engine, Lucio Bernard, director of Fiat Powertrain Technologies, told Automotive News. Internally, the groundwork...

  • BMW 1-series

    About a year ago we brought you a report that BMW was looking at a four-cylinder 3-series for American sale, but that was at the height of the fuel-price crisis, and since then talk of the efficient BMW four-bangers has died down. A recent report has breathed new life into the idea, however, and once again fuel efficiency lies at the root of the plan. Speaking with Bloomberg, BMW's top North American engineer, Tom Baloga, said that the four-cylinder may be the best solution to meeting higher fuel economy standards without seriously impacting performance - a key aspect to a marque that bills...

    Germans, luxury marques lead diesel's U.S. comeback

    It's easy to blame the economy or the consequent poor car market for the delay of diesels from Chrysler, Ford, General Motors, Honda, Nissan and Toyota, but that hasn't kept the Germans at BMW, Audi, Mercedes-Benz and Volkswagen from turning up the wick on oil-burners. In fact, it's quite the...
