Specially developed to fulfill the vehicle’s ‘Dual Concept’, the GX460’s powerful 4.6-liter V8 gasoline engine offers both extraordinarily smooth on-road performance and incredible torque for off-road driving. To achieve class-leading quietness and smoothness, Dual VVT-i (Variable Valve Timing-intelligent) varies intake and exhaust timing to increase torque, while significantly reducing exhaust emissions such as NOx (Nitrogen oxides) and HC (Hydrocarbons). Dual VVT-i, EGR (Exhaust Gas Recirculation)system and advanced low friction components combine to deliver higher output and torque than comparable 4.6-liter gasoline engines, with fuel economy similar to smaller 4.0-liter engines. For maximum SUV flexibility, a 6-speed automatic transmission offers fast linear acceleration, quiet high-speed cruising and excellent heavy-duty power.
