Overview
- Edmunds reports the new LS6 in the Stingray, Grand Sport, and Grand Sport X is rated at 535 horsepower and 520 lb-ft of torque.
- Drive says the Grand Sport X uses a front motor for all-wheel drive and delivers a reported 538 kW combined output with a short EV-only Stealth mode.
- Engine changes include a longer 100 mm stroke, forged pistons and rods, a new two-piece water jacket, a 13.0:1 compression ratio, and GM’s first use of both port and direct injection.
- Drive reports Australia’s access is unclear under stricter emissions rules as GMSV declined to confirm ANZ plans after fines of about AU$17,200 per Corvette Stingray sold last year.
- Edmunds expects the sixth‑gen small‑block to appear next in Chevy and GMC pickups and full-size SUVs, likely with iron-block versions and different tuning for those vehicles.
