The first Corvette made 150 horsepower from an inline-six — modest by any standard. The arrival of the small-block V8 in 1955 changed everything, and by 1957 fuel injection pushed output toward one horsepower per cubic inch, a benchmark of its era.
The big-block era of the C2 and C3 brought massive torque and, eventually, the emissions-driven decline of the 1970s. The C4's ZR-1 and its Lotus-engineered LT5 restored credibility with 405 horsepower, and the C5's LS1 began a family of engines legendary for their tunability.
The C6 pushed further with the 505-hp LS7 and the 638-hp supercharged ZR1. The C7's ZR1 reached 755 hp, the peak of the front-engine era. The C8 then reinvented performance with a mid-engine layout, a flat-plane-crank Z06, and the first hybrid E-Ray. The arc is unmistakable: Corvette has never stopped chasing more.
