Ford CEO Alan Mulally has never been shy of expressing his positive feelings towards Australia’s RWD Falcon sedan and during his latest visit Down Under he once again reaffirmed the long-term viability of the car but hinted that future generations could be radically different. Mulally confirmed that there will always be a place for large sedans like the Falcon but signalled that Ford’s next-generation of large sedans could move to a FWD platform.Ford is yet to decide on a new platform for the next Falcon but is keen to share development of the future Taurus with the Aussie sedan. At a press event held on Monday, Mulally warned that the RWD program was in doubt because of fuel economy-issues, reports GoAuto. When asked if Ford would switch to FWD, Mulally said “we haven’t decided that yet, but you are absolutely touching on the essence of it.”“RWD has some unique capabilities, but it will be yet to be determined whether we keep our unique RWD or whether the bigger sedans will need to be AWD or FWD,” he explained.Earlier this year Ford’s global product chief Derrick Kuzak confirmed that a RWD large-car development plan was underway but explained that most of the development work will take place in North America, as this is where most of the models based off the platform will be sold. Some of the new models that could be spawned from the single platform include new generations of the Mustang and Taurus, as well as large sedans for Ford and Lincoln.When asked about a possible export program for the Falcon, Mulally indicated that Ford would be more likely to borrow the knowledge behind it rather than the cars themselves. General Motors, meanwhile, has taken a much more active step than Ford in integrating its Australian subsidiary Holden and its expertise in RWD engineering. Holden was the primary development base for GM’s Zeta architecture, which underpins cars like the Commodore/Pontiac G8, and upcoming Camaro coupe.
