Yeah it'd be nice for the RL to have a V8, but the price point it will most likely be at is far lower than any of the V8 versions of its competitors. The cheapest of the bunch are the A6 4.2 and GS430, which are both over $50k. The 530i and E320 are also in that price range. If anything the RL competes against those cars, and the only one with a similar price, equipment level, and V8 is the GS430. Thought of as a competitor for the V6 models, the RL suddenly becomes much more relevant.
