The big news with the release of the third generation Camaro was the improved suspension. The front subframes and leaf-spring rear suspensions were history.
It was now equipped with a MacPherson strut front system, and a long torque arm and coil springs on the rear.
Also, the all new Camaro also featured a hatchback, a factory fuel injection option, four-speed automatic transmissions, five-speed manual transmissions, and base model four-cylinder engines (yawn).

1982 - The new 3rd generation Camaro was struggling with motors to match the inherent performance of the new Camaro. The base engine was the 2.5-liter "Iron Duke". Next up the line was the 112-horse 2.8-liter V6 (base engine in the Berlinetta). Then there was the (5.0 L) 305 CID four-barrel V8 rated at 145, which was the standard for the Z28. This engine in the Z28 could also be optioned with fuel injection which upped the power to 165. The fuel injection was the throttle body type.

The 82 Indy Pace Car was also a Camaro, but it is claimed that the actual car used for the event had a High Performance 350 V8 (5.7 L) that was not an actual option for the consumer. Also, note the T-top that was available on the 3rd generation.

1983 - For 83 the main excitement was the L69 5.0 Liter H.0. engine that was available for the Z28. Many of the parts for this motor came from the Corvette counterpart. It was rated at 190 horsepower. The L69 engine option was the only way the Camaro was going to compete with the 5.0 Mustang GT.
1984 - The 700R4 automatic transmission was now used in most Camaro's. The Berlinetta dashboard went digital galore. See this Berlinetta site for all kinds of info on the vehicle.

1985 - There was a new fuel injection option on the 2.8 L V6 which upped the ponies to 135, but the big new was the IROC-Z.
IROC represents the "International Race of Champions". The IROC-Z had 18 inch 5 spoke rims and appealing graphics, but the big appeal was in the motor.

The 5.0 Liter V8 carbureted engine was available, but the TPI (Tuned Port Injection) option gave the engine 215 very tractable horsepower. Only the automatic transmission was available with the TPI.

 1986 - Not much was going on with the 86. The new Center High Mount Stop Lamp requirement showed up on this model year. There were some vehicle paint improvements, and the exhaust system for the non-Z28 models was improved.
1987 - The (5.7-liter) 350 CID V8 was back! This was the most powerful motor that had found its way into a Camaro in the last 13 years, and more tractable, again, because of the Tuned Port Injection. This motor was only available with an automatic, but the 5.0 Liter TPI could now be had with a 5 speed standard shift.
More big news for the 87 was the new Camaro convertible. The last one, for the Camaro was way back in 1969.
They also discontinued the 4 banger this year. The carbureted 5.0 Liter V8 H.O. (High Output) was also discontinued, and replaced with a new 165 horsepower carbureted 5.0 which would become the standard Z28 motor. The Berlinetta was gone, and replaced with the LT option package.

 1988 - The Z28 was gone, and the IROC took over. The center mounted brake light that protruded from the rear glass was moved to the center of the spoiler, which was now standard on all Camaros (it actually was moved in 1987 on any Camaro that had a spoiler at the time).

There was an optional 1LE road racing package available with both the 5.0 and 5.7 Liter TPI engines. It included suspension modifications, an aluminum driveshaft, and heavy duty brakes.

1989 - The RS trim level returned. This was not the same as the Rally Sport version that had been previously manufactured. The RS was basically a trim package above the standard (base Sport Coupe) version of the vehicle. The 5.7 Liter TPI V8 was now kicking out 240 horsepower.
1990 - The IROC name was canned because Dodge now sponsored the International Race of Champions. The base V6 was punched out from 2.8 to 3.1 Liters and gained 5 horsepower to 140. Driver's side air bags were now standard.

1991 - The Z28 was back with an early 1990 introduction. It was basically still the IROC with some added ornamentation. The most powerful motor available was the 5.7 Liter TPI V8 which was now bumped up to 245 horsepower.
91 also saw the introduction of the rare "Camaro B4C pursuit vehicle" designed for law enforcement. It was a Z28 with RS badging, and the 1LE race package.

1992 - Everything remained pretty much as it had been the year before, in preparation for the 4th generation Camaro which would be released the following year. There was a 25th anniversary badge on the dash of all models, and an optional "Heritage" stripe package which could be added.
