Saab's new 9-4X crossover will be the first genuinely all-new Saab model in years, even though it still shares a lot of hardware with Cadillac's similar-size crossover underneath the sheetmetal, according to Motor Trend. Plus, a new 9-5 is on the way; by the time it arrives for the 2010 model year, the current car will be 12 years old.

The new one could be worth the wait, though. The report said that the new 9-5 will feature high-end chassis components such as aluminum hubs and suspension arms, hydraulic steering, and optional adaptive damping systems. And as befitting of a Saab, the new engines "will be all-turbo, including four-cylinder L850 units and GM's high-feature V-6s, starting at 2.8 liters; E85 versions will be prominent here, while Europe gets diesels, including a 1.9-liter, 200-horse twin-turbo."

Potential future engine options will likely be GM's brand-new 2.9-liter V-6 diesel, as well as GM's "plug 'n' play mild hybrid" system, which uses lithium-ion batteries and is capable of regenerative braking, according to the article.
