Ford's plans to manufacture the F-100 pickup, its answer for consumers who want a more fuel-efficient pickup, have been shelved (for now). A proposed smaller and lighter sibling to the popular F-150 pickup, the F-100 would have been built at the Michigan Truck Plant in Wayne, Michigan. Instead of designing a new small truck, one that consumers may not have warmed up to in the first place, Ford is reportedly making an 'unprecedented' investment in more fuel-efficient powerplants to drop under the hood of the best-selling F-150. According to Ford, much of the funding will be directed towards its EcoBoost engines that utilize turbocharging and direct injection to deliver increased power and efficiency. The company is also looking at a technology called 'ethanol boosting' which injects a small amount of the biofuel into the engine to increase fuel economy even further. Investing in new engine technology is expensive, but Ford is counting on reduced warranty costs (they have decreased by $1.2 billion in the past 18 months) to help offset development fees.
