Global Concepts (Part 2) Ford Prodigy The Prodigy hybrid-electric family car can deliver nearly 2.9 L/100 km (80 mpg) without sacrificing performance or functionality, according to Ford. It represents an interim stage between the company's P2000 research programs and its plans for an affordable, production hybrid in 2003. The sedan is built on a lightweight platform, features a modern aerodynamic design, and is powered by a low-storage-requirement (LSR) hybrid electric powertrain. The Prodigy improves on the P2000 LSR with advancements in powertrain refinement, aerodynamics, and rolling resistance. Its low-storage-requirement hybrid electric propulsion system includes an aluminum DIATA (Direct Injection, Aluminum Through Bolt Assembly) diesel engine, starter/alternator, automatically shifted manual transmission, and high-power battery. The four-cylinder, 1.2-L engine generates 55 kW (74 hp) at 4100 rpm. The car's starter/alternator-a small high-power electric motor packaged between the transmission and the engine-delivers up to 35 kW (47 hp) additional power for a total of 90 kW (121 hp). The engine is shut off at idle to conserve fuel, restarting less than 0.2 s after the driver touches the accelerator pedal. Prodigy's 0.199 coefficient of drag represents a 33% improvement over the P2000 LSR, helping to improve fuel economy by 4 mpg. Vehicle aerodynamics are aided by side-mounted cameras in place of conventional side-view mirrors, variable ride height, grille shutters, and shields under the car. The car's platform is based on Ford's extensive lightweight materials research with its 1080-kg (2390-lb) mass being about 455 kg (1000 lb) lighter than the average family sedan. Aluminum is used extensively for major components such as the engine and body. Carbon fiber, magnesium, and titanium parts add to mass savings.
