With the introduction of the IROC-Z, 1985 was a big year for the third-generation Chevy Camaro. Here’s a factory dealer film with the full Camaro lineup for ’85.

There were four Chevrolet Camaros for 1985: the base Sport Coupe, the luxury Berlinetta, the sporty Z28, and the brand-new IROC-Z, a tribute to the race-prepared Camaros used in the International Race of Champions (IROC) all-star series. In truth, the IROC-Z was an option package for the Z28, but in this Chevrolet video, the IROC is presented as a fourth stand-alone model. Hmm, looks like a good trivia question for future generations of Camaro enthusiasts.

Among other items, the IROC-Z package (B4Z, $659) included 16-inch directional tires on special five-spoke aluminum wheels with different offsets front and rear, an impressive list of suspension and steering upgrades, and distinctive graphics and badging. The IROC package was so popular it became standard on the Z28 in 1988, only to be dropped for 1991 when Chevrolet ended its support of the IROC series. (Dodge Daytonas and Avengers were used in the series from that point on.)

There’s a sobering moment near the opening of the video, when we are reminded that the base engine in the Sport Coupe for ’85 was the 2.5-liter LQ9 four-banger, which  boasted all of 88 hp. Oof. But on the plus side, there were three available 5.0-liter small-block V8s, including the LB9 with tuned port injection and 215 hp. We note that a four-cylinder engine is also offered on the 2019 Camaro, but it’s turbocharged and makes 275 hp. Time marches on. Video below.
