*The rating figure given is considered an approximation and is dependent on
engine characteristic as well as absolute value. The method upon which
engine torque is delivered through the transmission can vary considerably
depending on the physical engine characteristic, firing order, fuel and spark
strategy, turbo delivery and any traction limiting system that is utilised. The
life and durability of the gearbox internal parts is also considerably influenced
by factors other than engine output characteristics, for example oil type,
operating temperature and operating environment.
