Few expenses were spared in conceiving the Porsche Panamera, but consumers will avoid at least one cost of ownership: the ignominious gas-guzzler tax. Porsche has announced ratings for the 2010 sedan; it will get a combined figure of 18 mpg or 19 mpg from the EPA, depending on the model.

Maserati banks on Chrysler to boost global sales

Fiat CEO Sergio Marchionne has bold plans for the automaker's Maserati luxury sports car unit: to boost annual sales almost tenfold to 50,000 units from 5,675 last year.

Maserati will introduce two new sedans to replace its Quattroporte flagship model using technology from Chrysler's large sedans such as the Chrysler 300 and the Dodge Avenger.
