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.
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.
