The 2027 Corvette ZR1 1LZ Convertible is expected to be a refined evolution of the record-setting ZR1 platform, retaining the 5.5-liter twin-turbo LT7 V8 that produces over 1,064 horsepower in the 2026 model. For 2027, Chevrolet is expected to introduce minor performance and software improvements, slightly increasing output to roughly 1,100 horsepower while improving throttle response and cooling efficiency. This would allow 0–60 mph in about 2.2 seconds and a potential top speed approaching 230 mph, making it one of the fastest convertibles ever built.
