The new BMW 7-Series has just stepped out from behind the curtain, and it's detailed the period to a house only half full. Demand for BMW's big engines has dropped so low that the house of the roundel says it can make enough 8-bangers to persuade the world's request with just one period for four days. A component of BMW's supervisory lodge put it plainly: "We are producing the wrong engines here." Even the sixes, the seat of BMW's engine constellation, are being full out of production in Munich to be replaced by those with two fewer cylinders in 2011. When the phase-out is undivided, the group will be able to foster 560,000 4-cylinders per annum. Care for a BMW 716i, anybody?
