Follow the link below for product overview by TOVA. Anyway, it is not car review, and do not expect the site to give rating and driving feel of Honda HR-V. Head up to:

Part of the article as sample.
The HR-V engine is the R18A, adopted from the unit used on the 1.8 Civic. This engine features a 'high-dimensional balance' of fuel efficiency and power by (using) the SOHC VTEC mechanism. Key features of the R18A which targets the FE and EM (Emission) aspects are the SOHC VTEC mechanism which offers an economy-power cam operations configuration for VTEC-off/VTEC-on operations, a 'high-performance' air-flow sensor, and a 'high-rotation' high torque starter. (Though to be honest, I do not see how the starter can contribute to either FE or EM benefits.
The R18A features weight reduction with a 'light-weight' camshaft and power output is maximized without sacrifice to emissions by the use of a low back-pressure 'closed-coupled' catalyzer (catalytic converter). It features MoS2 (Molydebnum Disulfide) pattern coated (i.e. the coating is in a pattern, usually pokka-dot) pistons, the MoS2 reduces friction between the piston and the cylinder walls and the patterned coating allowing better retention of engine oil on the piston walls.
