Cadillac cars: What's new for 2007

More equipment for DTS, 6-speed automatic for STS and XLR

ALL MODELS: The warranty now covers the powertrain (engine, transmission, and parts that deliver power to the wheels), roadside assistance, and courtesy transportation during warranty repairs for 5 years or 100,000 miles (160,000 km).

CTS: No major changes. A new version is due next year.

CTS-V: No major changes. A new version is due next year.

STS-V: Unchanged; with 469 horsepower on tap, it remains the most powerful Cadillac ever offered.
