Deep dive: The 2027 Chevrolet Corvette’s all

Key Points:

• General Motors has unveiled the 6th generation Chevrolet Small Block V8, the 6.7-liter "LS6," debuting in the 2027 Corvette Stingray, Grand Sport, and Grand Sport X, delivering 535 horsepower and 520 lb-ft of torque—the most powerful base engine and highest naturally aspirated torque in Corvette history.
• The LS6 name honors GM's V8 heritage, linking back to previous LS6 engines and muscle car legends, while the new engine combines a 6.7-liter displacement with advanced engineering to achieve high power, wide torque band, and improved emissions without sacrificing fuel economy.
• Key technical highlights include a 13.0:1 compression ratio (the highest ever for a Corvette), an increased stroke from 92 mm to 100 mm, forged pistons and rods, port and direct fuel injection, a larger throttle body, and a new center-exit exhaust system praised for its distinctive sound.
• The LS6 engine is assembled at GM's Michigan Flint Engine Operations, marking a return to Flint, Michigan, where the original Small Block was produced from 1954 to 1999, reinforcing the engine's deep legacy and American muscle car heritage.
