Before the highly anticipated debut of the Cadillac CTS later today, pictures and details about Caddy's newest luxury sedan have surfaced.

The all-new CTS grows both in width and length, with a striking exterior that we've only seen parts of up until now. The interior gets a thorough redesign as well, with a new dash, steering wheel and instrument cluster that may finally bring it to the levels of its European competition.

At the top of the line, you'll the direct-injected, 3.6-liter V6, producing 300 HP and 270 lb.-ft. of torque. The new-to-the-CTS mill will be mated to a six-speed automatic, although in basic trim, you'll be able to row the gears yourself via a short throw, six-speed cog swapper. Power will naturally find its way down to the rear wheels, however, the 2008 model will offer a CTS-first: all-wheel-drive.

Later on, expect to find a V-series CTS, packing an additional two cylinders and producing adequate oomph to keep up with some of its hi-po rivals.

We'll have plenty more information available when the CTS is unveiled later, so stay tuned.
