The ’72 model was pretty much the same as the previous two years. Standard features were the same, as well as options for color, engines, etc. Majority of the models had power steering and air conditioning, while less than half had the tilted steering wheel or power windows. Six and a half percent had the LT1 engine. 6% had a close ratio four speed manual transmission, while 7% had the heavy duty. Zero to sixty for the V-8 engines include: LS5, 6.8 seconds; LT1, 6.9; and the base ZQ3 engine ran in 8.5 seconds. And, although the horsepower was less (1971 for the LT1 was 330 hp while ’72 was only 255), the performance was the same.
The ’71 model is close to identical to the ’70 model. The only major changes are a new resin process to change the body, and a different interior was developed. Also, the compression ratios were lowered to allow lower octane fuel. Standard features were the same as previous years. 1949 Corvettes were sold with the LT1 engine, eight of them being in the ZR1 model. Majority of the ’71 models had power steering, four speed manual transmission, and air conditioning. Less than half came with power windows or tilt steering wheels. Zero to sixty clocked in for the different engines as the following: L48, 7.1 seconds; LS6, 5.3; and the LT1 came in at 6 seconds.
Refinements for the Vette in 1970 include: an “ice cube tray” design grille to match the side louvers, rectangular front lights, square exhaust tips, fender flares, and improved bucket seats and seatbelt containers. Standard equipment include: front and rear disc brakes, headlight washers, carpeting, wheel trim rings, center console, and an all vinyl upholestry interior. 70.5% of the Vettes sold had the 4 speed manual trasmission, while 68.8% had power steering, and less than half had tilt steering wheel, power windows, and air conditioning. A Corvette with a L56 engine can reach 60 mph in 7 seconds, while the LT1 engine could reach 60 mph in 5.7 seconds and has the top speed of 122.
The Stingray name appeared on the front fenders after being absent for a year. The back up lights were adjoined to the center taillights. The ignition is now on the steering column, and the depression door button was removed as a key lock supplanted it. New standard features include: front and rear disc brakes, headlight washers, center console, wheel trim rings, carpeting, and all vinyl upholestry. 60% of the Vettes from ’69 came with power steering, which is SIGNIFICANTLY more than previous years of only 10-20%. 78.4% had the four speed manual transmission, one in four had power windows, and the 350 cid 300hp could reach 60 mph in 8.4 seconds.
’68 was another year of Corvette for major remodeling. The fast back was replaced with a tunneled roof coupe. It had a removable rear window, and a two piece roof, called a “T Top”. The front was more aerodynamic, and the headlights were hidden as usual, though they were now vacuum operated instead of electrically. Chrome was eliminated from the sides, and the door handles were replaced with push buttons. 80% of the models were 4 speed transmission and had tinted glass. Top speed was 142, and the L79 could go to 60 in 6.3 seconds, while the L71 only did 7.7 seconds.
The ’67 Vette is considerably the best looking of the Sting Rays. The Big Block engines came with a large air scoop instead of the previous power blister. There were now 5 side louvers slanted towards the front of the car. The parking break was now in the center console instead of under the dash, and very minor changes were also made to the interior. Other innovations include: four way flashers, directional signals with a lane changing function, larger interior vent ports, and folding seat back latches. On the rear were now twin rounded taillghts, and the back up lights were now relocated to above the license plates. Only this year were the wheels made with a knock off center. 88% of the ’67 vettes were sold with the four speed manual transmission, and a 10% amount had the Powerglide automatic transmission. Hardly any were sold with power brakes, power steering, or air conditioning. The new Vette could reach 60 in 7.8 seconds.
New ’66 models were different for new: plated, cast metal grille with an “egg crate” insert, chrome plated exhaust bezels, spoke styl wheel covers, vinyl covered headliner, and the elimination of roof vents. The side louvers remained, and the new 427 engine came with the power bulge hood. Only 2% of the vettes sold had the 3 speed transmission, while 89 had the four speed manual transmission. 13% had a tilting steering wheel, and 20% had power steering.
