The mid-size CTS sports sedan made history in 2003 as the first RWD vehicle in Cadillac's fleet since 1979 and the first to offer a manual transmission on a rear-drive platform in half a century. The RWD Sigma platform for CTS features an extended wheelbase and wide track with wheels set on the corners. Inside a cabin for five, the exterior theme of crisp forms and angular features is expressed in a monochromatic treatment.

The 2005 editions of the CTS offer three options for powertrains. A new base model rolls out with a 2.8-liter V6 VVT engine pumping 210 hp. The upgraded CTS supports a 3.6-liter V6 with VVT and output pushed to 255 hp. A new Aisin six-speed manual transmission or a five-speed Hydra-Matic automatic, works on either plant.

The high-performance model goes by the name of CTS-V, with that 'V' tacked to the CTS label perhaps to denote 'velocity.' It has a version of the Corvette's LS6 V8 under the hood that churns with 400 hp and renders sub-5-second times for the run to 60 mph. The CTS-V also carries retuned suspension components, Brembo brakes and high-performance Goodyear Eagle run-flat tires.

The name traces back 50 years in Cadillac culture, but current issues contain the high-tech innovations of a contemporary vehicle. Electronic controls and computer-managed mechanical systems improve vehicle stability and safety, visibility, communications and even passenger comfort. Three versions continue in 2005 with a base DeVille applying fabric seat upholstery on a bench-style front seat split in 40/20/40 sections with fold-down center armrest. The DeVille DHS (High Luxury Sedan) has the same seat but piles on comfort and convenience items, while the DTS (DeVille Touring Sedan) installs front buckets clad in leather.

Powertrain is a NorthStar 4.6-liter V8 tuned to 275 hp in the DeVille and DHS but 290 hp in the DTS. Options for the DeVille extend to Night Vision thermal imaging. Further, an armored edition -- for those who need security and protection when motoring -- shows up in standard length or a model with eight-inch wheelbase extension, and both bring features like ballistic steel and glass, a run-flat wheel and tire system and self-sealing fuel tank. Three new colors work in 2005: Green Silk, Light Cashmere and Glacier Gold.

Cadillac's premier SUV leads the luxury class as the most powerful full-size SUV. It rides on GM's full-size truck chassis and carries many mechanical weapons for road combat, along with every convenience in a leather-wrapped passenger compartment that seats seven in luxury. The top edition, outfitted with an automatic AWD traction device, draws from an enormous 6.0-liter V8 that makes 345 hp. Power is applied to all wheels through an AWD mechanism that's always engaged.

Also automatic is the Z55 Autoride suspension with continuously variable road-sensing damping and air-leveling shock absorbers for precise ride control. The RWD Escalade also earns the big 6.0-liter V8, available by mid-year. A new chrome-trimmed instrument cluster goes into all 2005 Escalade models, and the navigation system has an upgraded touch-screen. Additional color selections appear on the chart like Riptide, a teal blue metallic tint. (CONTINUED...)
