The new Cadillac STS is about as far removed from its Seville ancestors, as Age of Empires is from Pong ... and about as sophisticated and exciting.

When European luxury marques first started pushing their presence on the North American market of the mid-'70s, the job of securing North American interests was entrusted to the Cadillac Seville sedan (the Seville name did grace an Eldorado coupe trim level back in the late '50s).

The one main drawback to Seville as a German-Touring-Car fighter, though, was that it looked to much like a Chevy, which is actually what it was — a revised Nova ... and not the good Nova, either! Although, it did have a rear-wheel drive platform and the awesome Olds 350 V8 (fitted with fuel-injection, no less -- a first for North American cars).

Over the years, in the face of some pretty tough economic and fuel-crisis times, Seville became a front-wheel-drive shadow of its former glorious self. It started making a comeback in the '90s with a new V8 (Northstar) and well-thought-out interior and exterior treatments, but it really gets its Mojo back with the latest generation.

The Seville name had adopted the STS moniker (never quite clear what it stood for, but Seville Touring Sedan is the most popular explanation) as first a trim level, then as a model designation in conjunction with SLS (reportedly for Seville Luxury Sedan). The car now becomes strictly STS, in keeping with Cadillac's new letter-designated car lineup.

Rear wheel drive is back and STS takes full advantage of it in its quest for Performance Car acceptance. There is a bit of play in the rear-end under power on traction-sensitive surfaces, but the car corrects itself quickly enough thanks to standard traction control.

Power comes from a choice of Northstar variants — a 255-hp 3.6 V6 or a 320-hp 4.6 V8. Both feature variable valve timing to fulfil power and economy goals. Our test V6 showed an obvious difference in sensation and sound from the all-out grunt of the V8, but if you're not aware of the V8's seething energy you'll be impressed by the launch and progressive buildup as the V6 climbs the rev range.

It is helped along by a silky smooth 5-speed automatic. General Motors makes the best automatics on the market, and this sequentially shiftable slushbox is no exception. In fully automatic mode, it shifts smoothly and seamlessly. In "Sport" mode, it performs like there's a little race car driver shifting away — holding gears when the driver lifts off the throttle, or executing a downshift while powering out of a corner. And a manual shiftgate allows the driver to nudge up or down through the gears manually.

Now, all this racecar stuff wouldn't do much good if the car itself weren't so pleasant to drive (witness a Dodge Caravan with AutoStick), but the STS has also been endowed with the best of suspension and chassis tuning from the motorsports world.

Fully independent, the suspension nicely controls transfers of weight under acceleration, braking or lateral forces. Zipping along a winding country road becomes like the world's super-smoothest rollercoaster, with positive changes in direction and thrilling squirts of acceleration to the next rail-like switch in direction.

Mind you, it doesn't hurt that the interior retains the comfort and convenience on which Cadillac has made its name. The upholstery is buttery smooth leather and the seats are individually contoured for great support under all driving stress.

Technology is showcased through a key-fob transponder (that allows you to open doors simply by working the door handle, and start the car by pushing a button), and the availability of heated seats all around and digital-surround sound (available on all but the base V6 version).

It all adds up to a thoroughly modern, completely enjoyable Seville ... er ... STS. It is a rear-wheel-drive tour de force that makes you forget about all those chop-tailed sedans and chromed-up, padded-roof Chevys in Cadillac's past.
