Noted Porsche tuner, RUF unveiled its latest Porsche 911 (997) — the RUF Rt 12 — at the Essen Motor Show, giving some lucky Europeans a chance to salivate over its awesomeness. In addition to RUF's traditional aerodynamics additions, the Rt 12 uses a twin-turbo setup to wring 650hp out of a tricked-out, 3.8-liter version of the Porsche's flat-six motor. Two-wheel drive or all-wheel? Decisions. Decisions.
