New for 2008: fuel economy & versatility are driving forces.(automobiles, sport-utility vehicles, and minivans)(Product/service evaluation)

As the fall new-model season kicks into gear, you'll see a wide range of new and redesigned vehicles hitting the road. These include revamped versions of such popular mainstays as the Chevrolet Malibu, Honda Accord, and Dodge Grand Caravan, as well as newcomers such as Mercedes-Benz's tiny and quirky Smart ForTwo city car.

Overall, car-based SUVs and so-called crossovers, such as the new Infiniti EX35 and Nissan Rogue, continue to be the fastest-growing segment of the market, as buyers increasingly look for vehicles with the versatility of a traditional SUV yet with more carlike handling, ride comfort, and fuel economy. There will also be more choices in alternative powertrains, including hybrid, flex-fuel, and clean-diesel vehicles.

Here we present a preview of some notable models, with insights from our auto experts. Look for full tests in upcoming issues and on ConsumerReports.org.

Smart ForTwo

Coming to the U.S. this year is an update of this tiny two-passenger city car now sold in Europe and Canada. Less than 9 feet long, the Smart is designed for easy parking. Still, its high roof and rear-mounted engine allow two tall people to fit easily in the cockpit. Convertible and coupe versions will be available. The Smart will probably be powered by an 84-horsepower, 1.0-liter turbocharged three-cylinder gasoline engine.

CR'S TAKE. Last year, we tested a diesel-powered Canadian version of the previous-generation Smart. It exhibited clumsy handling, a harsh ride, and a lurching transmission, making it the worst vehicle we've tested in recent years. The gas-powered U.S. version is redesigned and, we hope, better.
