The R series engine has a compression ratio of 10.5:1, features a "drive by wire" throttle system which is computer controlled to reduce pumping losses and create a smooth torque curve.

The engine uses many advanced technologies to improve fuel economy and reduce friction.

Piston rings are given an ion plating and weight is reduced with plastic and aluminum parts and variable length intake manifolds that maintain ram air at a wide RPM range.

The engine also features piston cooling jets, previously available only on high performance engines, and in the ninth-generation 1.8L Civic (2012-2015) the pistons are treated with molybdenum disulfide applied in a polka-dot pattern.

The automatic transmission model is rated at California Air Resources Board (CARB) ULEV-2 (Ultra Low Emissions Vehicle) with fuel economy 25 mpg‑US (9.4 L/100 km; 30 mpg‑imp) city, and 36 mpg‑US (6.5 L/100 km; 43 mpg‑imp) highway.
