Hemmings Motor News Blog

Hemmings Motor News has been around since 1954. We're proud of our heritage, but we're also more than the Hemmings full of classifieds that your father subscribed to. Aside from new editorial content every month in Hemmings, we have three monthly magazines: Hemmings Muscle Machines, Hemmings Classic Car and Hemmings Sports and Exotic Car.

While our editors traverse the country to find the best content for those magazines, we find other oddities related to the old-car hobby that we really had no place for - until now. With this blog, we're giving you a behind-the-scenes look at what we see and what we do during the course of putting out some of the finest automotive magazines you'll ever read.

The Chevrolet Camaro's Horsepower History

Posted February 25, 2015 9:30 AM by dstrohl

Excluding its seven-year absence from 2003 through 2009, the Chevrolet Camaro has been a muscle car staple since its debut in 1967. It's not uncommon to hear how today's production cars can't hold a candle to the muscle cars of yore, but a new chart from GM, graphing the production Camaro's horsepower across the generations paints something of a different story, while illustrating the evolution of technology (and consumer tastes) over five decades.

When the Camaro debuted in 1967, its base inline six-cylinder engine produced 140 horsepower while the best available 396-cu.in. V-8 version made 375 horsepower. Both figures are rated in SAE gross horsepower, which was, perhaps, a bit misleading to consumers. Measured under laboratory conditions, with ideal tuning and no parasitic loss (from features like power steering pumps, A/C compressors, water pumps, alternators and fan clutches), SAE gross ratings may have portrayed what an engine was capable of, but certainly not what it actually produced in the real world.

How does your Camaro's hp rank against its brethren?
