A new hybrid powertrain is on the horizon, combining a 535‑horsepower LS6 V‑8 with an additional 186‑horsepower electric boost from a ZR1X module. The result is a 721‑horsepower “Grand Sport X” engine that promises blistering acceleration and a thrilling driving experience. Engineers say the electric assist will be integrated seamlessly, providing instant torque while keeping the V‑8’s classic sound and performance intact. This development hints at a future where high‑performance muscle cars blend traditional power with modern electric technology.
Take a 535-hp LS6 V-8 and stir in the 186-hp electric assistance from a ZR1X, and you get 721 horses of Grand Sport X goodness.
