1980 Chevrolet Corvette

A redesigned front-end included an integral air dam and three-piece spoiler, which improved radiator airflow and lowered the car's drag coefficient from 0.50 to 0.44. A rear spoiler was built into the redesigned back panel. Air conditioning, power windows, and tilt-telescopic steering wheel were now all standard equipment. Cornering lights appeared on the front fenders. Engineers found ways to lose nearly 250 pounds off the car, such as switching from cast-iron to aluminum on the intake manifold and differential housing. At 3,495 pounds, it was the lightest Corvette since 1968. Goodyear Eagle high-performance radial tires became optional, starting a three-decade relationship between Chevrolet and the Ohio-based tire company. Despite improvements, sales dropped to 40,614 units.
