This ain't your grandpa's Caddy. GM’s keeping the momentum going at its luxury brand with a host of wonderfully powerful and agile new models under the new “V-Series” banner. First came the CTS-V, a 400-horsepower mid-size sedan developed through a zillion laps at the famed Nürburgring racetrack in Germany that could give the BMW M5 headaches — and for a lot less money. Now there’s the new Cadillac STS-V, with a monster 440-horsepower engine tucked into a very capable chassis surrounded by sophisticated styling, technology and an attractive and sumptuous cabin. To get the lowdown on this sensational luxury sports sedan, and for info on future V-Series offerings from Cadillac, pick up the February 2005 issue and read Detroit Editor Matt DeLorenzo’s cover story.
