DETROIT, March 10 -- What do you get when you cross a sport- ute with a sports car? One thing's sure: the all-new Porsche Cayenne goes fast on-road and off. Catch a ride in one of the year's most controversial new products this week on TheCarConnection.com .

Then switch seats for a spin through sunny Spain as TCC drives the all- new, all-aluminum Jaguar XJ. And see what's in store for the British marque as it rethinks its aggressive growth plans.

Other reviews include the 2004 Pontiac Grand Prix. Visit TheCarConnection.com to find out if it's driving in the right direction. You'll also drive two of the newest from Mercedes-Benz, the all-new E-wagon and the exclusive SL600. This week's spy shot captures the next-generation Mercedes SLK.

There were dozens of hot products unveiled in Switzerland last week, and you'd be cuckoo to miss TCC's complete coverage of the Geneva Motor Show. See the all-new Chrysler Airflite, the production, 180-mph Bentley Continental GT and more. Then take a trip "down under," as TheCarConnection visits the Melbourne Motor Show. Is there another GTO-wannabe ready to head your way?

Rising gas prices have automakers talking higher mileage. But that was only one of the hot topics at this year's gathering of the Society of Automotive Engineers. TCC was there and takes a look at the latest gadgets and gizmos.

Then check out the hybrid class of 2003. There aren't many of these high- mileage gas/electrics available -- yet -- but just wait until next year.

If you have to ask, you probably can't afford the $320,000 Rolls-Royce Phantom, but come along for the ride, anyway -- and then see what the stately British marque is doing to make itself relevant again. Is the Phantom really just a fancy Ford Taurus? You may be surprised.

And check out TCC's newest column: The Mechanic's Tale -- the inside word from the man who keeps your car running.

This week's TCC Tips will help you pick the right child seat, and then show how to keep your car running right.
