Summary: Kelley Blue Book recently had a chance to drive the new Cadillac CTS-V. In most respects it's exactly the same as the regular CTS luxury sedan. It still has a roomy, comfortable interior, plenty of soft touch materials, cool ambient lighting and a navigation system that audibly warns you of dangers ahead. In fact, besides a slightly firmer ride this could be the regular CTS. At least until you turn, accelerate or brake. Cadillac describes it as the "fastest V8 production sedan in the world."
