What a difference a letter can make. Having an extra one or two after your name shows the world you're better schooled than most. But the right application of a special letter on a luxury sedan signals something else altogether: it's a mark of performance. So a BMW 5 Series becomes an M5. A Mercedes-Benz E-Class becomes an E63 AMG. A Jaguar XF becomes an XFR or even an XFR-S. An Audi A6 becomes an S6 or RS6.
You get the picture, and so does Cadillac: with the CTS-V it launched its own assault on the best European machinery. But while an ATS-V is expected to follow with the same formula applied to GM's new 3 Series rival, don't expect the same of the Cadillac XTS flagship.
According to reports, Cadillac has ruled out the possibility of an XTS-V. The new XTS is powered by a V6 engine, but while a turbo variant could follow, we're told not to expect a V8 model, let alone a performance version. Apparently Cadillac feels its flagship isn't meant to go fast, focusing instead on its vast space that includes enough room in the back seat to cross one's legs and enough space in the trunk for four golf bags.
What Cadillac is reportedly looking into, however, is an even bigger model. That's right, the full-size XTS apparently isn't big enough, so Cadillac is looking at a flagship that will be larger still – something like a proper BMW 7 Series competitor. Which we can only hope will hold, like, at least five golf bags, easy.
