Welcome back to Hobby Car Corvettes, as we wrap up the final years of the C3 Vette series. We began this series with the exciting launch of the third generation of Corvettes in 1968, and this week we bring you the second to final year, the 1981 Corvette. Each post, we discuss the highs and lows, the additions and removals, of each Corvette born into the third generation.
Here at Hobby Car Corvettes, located in Martinsburg, PA, we began this series because we personally think the third generation of Corvettes was, and remains, the best! We love all Corvettes, but let’s be honest, everyone has favorites. The third generation was ours.
Let’s dive right in and find out what Chevrolet had in store for the 1981 Corvette.
HELLO BOWLING GREEN, KENTUCKY!
The year of the 1981 Corvette brought with it yet another milestone. After many years of sole Corvette production occurring in St. Louis, Missouri, this year, Chevrolet opened a brand-new, high-tech facility in Bowling Green, Kentucky. This is where Chevrolet would now produce all Corvettes, and only Corvettes. The St. Louis plant was not Corvette exclusive, and so this was seen as an upgrade and opportunity to solely focus on perfecting the Corvette.
You have probably heard of Bowling Green before, because today, that is where you will find the National Corvette Museum. If you have the opportunity to visit, we enthusiastically recommend it!
The facility that GM purchased for the development of the Corvette plant had originally been an air-conditioning plant, but was fully refurbished by General Motors to be used only for the production of Chevy Corvettes. This facility would utilize the latest automated manufacturing processes which improved consistency in quality. Also included in the new Bowling Green facility was a more efficient and updated paint shop allowing for more durable enamels and a new clear coat finishing. You will notice in the specs and details below, this year offered not only more colors than ever before, but also the options of two-tones and many metallic colors.
The actual announcement of the move to a new Corvette facility was released on March 26, 1979. One of the main reasons for the eventual move in 1981 was age of the St. Louis facility, which had been built in 1920. Not only was it outdated, it was also small and Corvette had frankly outgrown what the facility had to offer.
Production of the 1981 Corvette continued in the St. Louis plant until August 1, 1981. The last Corvette to be completed in St. Louis occurred in the Fisher Mill building on Natural Bridge Avenue. The first Corvette to roll off production in the new Bowling Green plant did so on June 1, 1981. This meant that there were two months where Corvettes were being produced in two locations. Many of the workers from St. Louis did relocate to Bowling Green to continue their work with Corvettes, evidence of the commitment of the workers and the fulfillment that working in a Corvette plant provided.
1981 CORVETTE AESTHETICS
While very few aesthetic changes occurred in 1981, the most notable was an interior upgrade. A modernized dashboard offered new user-friendly features. Some features added included a standard quartz clock and electronic tuning for all factory radios. Another new option would be a six-way power driver’s seat. This introduced the ability to recline.
On the outside, the 1981 Corvette was nearly identical to the 1980 Corvette. The biggest difference on the outside was the new paint option, RPO D84, which was a 1981 exclusive option. This year, you could opt for a two-tone paint job.
This was decided to be an option to showcase the high-tech capabilities of the new Bowling Green facility. There were four two-tone combinations available—Beige/Dark Red, Silver/Dark Blue, Silver/Charcoal, and Autumn Red/Dark Claret.
1981 CORVETTE MECHANICS
Similar to aesthetics, very few changes were made to the mechanics of the 1981 Corvette. Chevrolet clearly had their hands full with the big move. In addition, more people were accepting the inevitable end of an era. It was clear that the third generation was coming to an end. That being said, there was little need for a major makeover or mechanical rework. Perhaps they were saving any big changes for the launch of a new generation.
The one change worth mentioning, was the single engine option in 1981. As regulations and standards continued to tighten, Chevrolet knew they would never give up the Corvette, but they accepted that they would have to put in the work to improve its fuel compliance rating. The effort made to do this resulted in a single, reworked engine designated as L81, while the previous L48 and L82 350 ci engines were retired.
The 1981 engine option was a 350 ci V-8, rated at 190 hp. The new L81 engine featured magnesium valve covers, a stainless steel exhaust manifold, and an auxiliary electric cooling fan that worked in conjunction with a smaller, engine driven cooling fan, which aided in noise reduction.
An exciting introduction to the 1981 Corvette was the use of computer command control (CCC). This technology utilized electronics to integrate the emissions and fuel systems, which reduced smog and fuel consumption. CCC was also used with the automatic transmission’s new lockup torque-convertor clutch. This change eliminated gas-eating frictional losses through the convertor.
Chevrolet also made efforts to reduce Corvette weight, which would ultimately benefit fuel efficiency. One major weight reduction was the change from a plastic mono-leaf fiberglass rear spring which weighed 8 pounds, in comparison to the previous 44 pound steel leaf springs.
DID YOU KNOW
1981 offered more color options than any other year.
This was the first time that Corvettes were running off the assembly lines in two locations simultaneously.
The L81 engine could be mated to a four-speed manual transmission, allowing California drivers to purchase a manual-transmission Corvette for the first time since 1975.
The number of Corvettes sold in 1980, in comparison with the total sold in 1981, only differed by 7 Corvettes. With 40,606 total 1981 Corvettes sold, numbers remained notable, even with a steep price increase. The 1981 Corvette sold for over $16,000.
While 1981 brought few exciting changes to the Corvette specifically, the introduction of the Bowling Green facility offered great potential for the future of the Corvette.
As was stated in a 1981 Corvette brochure,
“The Bowling Green facility, which will build Corvettes exclusively, is an investment in Corvette’s future. It represents the experience and knowledge learned over all those years.”
