The QR25DE engine has a compact balancer shaft that significantly reduces noise and vibration, giving an exceptionally quiet, comfortable drive.

A single accessory drive belt helps reduce overall engine weight and size. The automatic tensioner maintains proper tension at all times, reducing wear.

The system opens and closes the throttle electronically instead of using a conventional cable. The result is more precise throttle control with stronger performance and better fuel economy.

Arrangement of engine compartment components allows efficient servicing of common maintenance items. Color-coding allows easy recognition of common maintenance items.

This mode enables the engine to function in a reduced capacity in case of failure by any one of four critical components (coolant temperature sensor, crankshaft angle sensor, throttle position sensor, or airflow meter).

In the event of an emissions-related incident, the OBD II illuminates a "Service Engine Soon" light to alert the driver, thereby reducing the risk of damage to expensive components.

Fluid in selected engine mounts absorbs engine vibrations before they reach the passenger compartment, reducing engine noise and vibration for improved passenger comfort.
