It had a 1.6L electronic fuel injected 4-cylinder engine that produced 102 horsepower and was tilted 70° to accommodate the low profile hood. Power was distributed through an advanced 3-speed automatic transaxle.The radiator was an advanced aluminum design that, along with the A/C condenser, was located in the rear quarter panels. Specially designed Goodyear tires had an aerodynamic tread pattern while the wheels were covered by a flexible membrane cover. A computer controlled vehicle height, attitude, and spoiler adjustments, all of which were speed sensitive and/or manually controlled. It had a steel and kevlar body to minimize weight, as well as aerodynamic headlamps, concealed windshield wipers, and flush underbody, all designed to minimize resistance.
