This model is powered by a 5.0 L 1GZ-FE V12, rated at 206 kW (276 hp; 280 PS) in Japanese models and 220 kW (295 hp; 299 PS) at 5200 rpm in export models.[citation needed] Torque was rated at 460 N⋅m (340 lbf⋅ft) at 4000 rpm for both Japanese and export versions. It was initially equipped with a 4-speed A342E automatic, until a 6-speed "intelligent" transmission arrived in 2005. It also features air suspension. The Century remains the first and only Japanese front-engine, rear-wheel-drive production car equipped with a V12, and it is Toyota's first V12 engine.[13] As this is a top level luxury flagship, private owners are comfortable with the yearly road tax bill.
