Dyno-tastic! Infiniti G37 on the rollers
According to Automobile's dyno graphs, the new 3.7L produces 287 hp and 236 ft-lbs. of torque at the rear wheels, which means friction in the drivetrain accounts for about a 13% loss in power from the flywheel. The previous 3.5L VQ V6 used in the 2007 G35 coupe produces 236 hp and 218 ft-lbs. of torque at the wheels. This means that although the new engine is only 5.6 percent larger in displacement, it produces almost 22 percent more power than the engine it replaces. Automobile does note that it can't be sure if such a large increase in power is due to the new engine or reduced friction in the drivetrain, but suspects that since the drivetrains of the 2007 and 2008 model are similar that the gains are mostly from the motor.
