This might not be the Cadillac for rockers who load up their iPods with Led Zeppelin, but neither is the new DTS meant for the folks who spend Sunday evenings watching Lawrence Welk reruns. Its restrained styling, front-drive platform and mild-mannered V8s suggest the DTS is the most traditional of today's Cadillac, but it's also full of modern technology and electronic goodies. Unlike many high-end luxury cars these days, there's no need to study an encyclopedic owner's manual to make the DTS do its job, which is to provide faultless motoring. This is a rational luxury car, aimed at buyers who place affordable and user-friendly alongside large and luxurious on their automotive wish lists. Formerly wearing the DeVille nameplate, Cadillac's full-size luxury sedan sports a new badge, fresh body lines, a redesigned interior, upgraded running gear and suspension refinements. It is offered in a single model, with a single interior, but with a number of option packages (including a front bench seat), and two levels of Northstar V8 power for a wide range of personalization. However outfitted, the DTS continues the Cadillac legacy of impeccable road manners and a warm, spacious interior. Yet with its improved chassis, suspension and larger running gear, the new Cadillac DTS also offers crisp handling and improved grip for another layer of driving enjoyment that we welcome.
