1GZ-FE
The 1GZ-FE is a 4,996 cc (5.0 L) 48-valve DOHC V12 engine with variable valve timing (VVT-i). Bore is 81 mm and stroke is 80.8 mm, with a compression ratio of 10.5:1. The official power output advertised in Japan per the gentlemen's agreement is 206 kW (276 hp; 280 PS) at 5,200 rpm, though it was advertised as 220 kW (295 hp; 299 PS) in export markets. Peak torque of 481 N⋅m (355 lbf⋅ft) is at 4,000 rpm with over 400 N⋅m (295 lbf⋅ft) available from as little as 1200 rpm. The Electronic fuel-injection system is controlled by two ECUs, one for each bank of six cylinders. The engine is capable of running on either bank should a malfunction occur.[2]
In 2010 the standard engine was revised in order to meet tough fuel economy and emissions standards, reducing power slightly and peak torque to 460 N⋅m (339 lbf⋅ft) although this torque figure had been advertised in export markets since at least 2004.[3]
