100EX is powered by a 9-litre V16, 64-valve engine. Natural aspiration was chosen over turbo or supercharging to give the instant, yet perfectly smooth style of pick-up which has so impressed in the Phantom. Drive is delivered through a six-speed automatic gearbox. http://www.autointell-news.com/euro...e-bmw/rolls-100ex-04/rolls-royce-100ex-04.htm http://www.omniauto.it/a440.html
