Cadillac officially announced the 2011 CTS Coupe Monday morning, promising to show the car publicly next week at the Los Angeles auto show.

First shown in concept form nearly two years ago, the car was originally expected to be launched earlier this year.

Cadillac CTS Coupe will come with a 3.6-liter V-6 engine, rated at 304 horsepower. A higher horsepower V-Series will is also planned.

Rolls-Royce does things differently.

Doors open backwards, hood ornaments are powered, engine displacement is measured to two decimal places, and headliners are designed to mimic the night sky.

Even the company’s product launches are unique. At the 2008 Geneva show, Rolls-Royce will formally announce the Phantom Coupe. This comes over a year after the Phantom Drophead Coupe was launched.

This is not your ordinary coupe/convertible timeline.The fixed-head Phantom is expected to be much like its convertible precursor. The same 6.75-liter V-12 sits under the long hood, making a familiar 453 hp and 532 lb-ft of torque. The Coupe can be equipped with the starlight headliner seen on the 101EX concept and also available in the four-door Phantom.
