The all-new, technology-intensive XV8 concept engine provides the power and smoothness of a premium V8 and the fuel efficiency of a V6. Yet it fits into an engine bay sized for the width of a V6 and the length of a four-cylinder.

The all-aluminum 4.3-liter XV8 utilizes a unique three-valves-per-cylinder combustion chamber configuration, supporting the optimization of an air-assisted direct fuel injection system. The configuration features an industry first: two camshafts in the block. The XV8 produces 224 kW (300 horsepower) and 400 Nm (295 lb-ft) of torque.
