They will be the first new vehicles to be fully developed under Tata, but they are all several years away.

For now, Jaguar is pushing its recently redesigned XJ. Jaguar executives think it could boost the brand's global sales by as much as a half this year to 75,000 cars.

To improve its quality image in the United States, Jaguar is offering 5-year/50,000-mile scheduled free maintenance on its 2011 models.

Here is a rundown of Jaguar's product plans for 2010-13:

X-Type: Jaguar has lacked a car priced under $40,000 in the United States since the small sedan was pulled after the 2008 model year. But Tata has approved a new four- or five-door to compete with the BMW 3 series and Mercedes-Benz C class. The platform and architecture will be shared with the next-generation XK coupe and convertible and a new small 2+2 sports car. It could go on sale in 2014.

Sports car: A car that may be called the XE could go on sale as early as 2012. It would compete with the Porsche Boxster.

XJ: A redesigned sedan with an all-aluminum body went on sale in the United States in May. The all-new design moves away from the conservative look of its predecessor. With its coupelike profile and a glass panoramic roof, the new sedan competes against the Mercedes-Benz S class and Audi A8. The long-wheelbase XJL replaces the Vanden Plas version.

XF: The sedan is likely to be redesigned in 2014. Jaguar is working on a long-wheelbase version for China and a station wagon for Europe. Neither is destined for the United States. A coupe is possible in 2013 and is likely to be sold in the United States.

XK: The coupe and convertible may be restyled in 2013.
