ABSTRACT: The technical feasibility of superefficient family cars has been demonstrated. Yet it has -
promised vehicle performance, safety, cost, manufacturability, or marketability. Industry experimentation has tended to
focus on improving performance, or on implementing hybrid-electric drivesystems in essentially conventional vehicles,
or on reducing mass and drag, or on improving safety—but has rarely attempted to optimize all of these as a system.
Maximizing benefits through synergies between platform, ponent, and drivesystem design parameters seems
poorly understood. Whole-system engineering-design is essential to move mercial viability.
Second-by-second simulations and performance modeling provide evidence for automobiles 3–4x more fuel-efficient
than today’s, with emissions approximating the California Air Resource Board’s proposed Equivalent Zero Emission
Vehicle requirement for hybrids (~ x ULEV), and with safety, performance, and marketability surpassing that of many
current automobiles. mercial ess of such designs depends on the concurrent optimization of numerous pa-
