The CR-V's diesel line-up, expected to account for more than 60% of sales, has been enhanced with the addition of the all-new 160 PS 1.6 litre i-DTEC four-cylinder unit from Honda's Earth Dreams Technology series, first introduced in 2013 as a 1.6 litre i-DTEC with 120 PS.

This unique-to-Europe engine replaces the 2.2-litre i-DTEC diesel unit. Aided by a new two-stage turbo, it offers higher power output and better power delivery, as well as superior levels of efficiency and significantly reduced CO2 emissions. As a result, the new engine has the best power-to-consumption ratio available in its segment.

A number of innovations reduce frictional energy losses, with the engine friction of the i-DTEC engine now 37% lower than its predecessor and equivalent to that of a petrol unit. The result is highly impressive fuel economy of 4.9 l/100km (combined cycle).

The engine produces a maximum power of 160 PS (a 6% increase over the 2.2-litre diesel predecessor) and 350 Nm of torque, while emitting a 129 g/km of CO2 (an 11% improvement and a figure not bettered by any similarly-powered competitor) when mated to the six-speed manual transmission.

The 2-stage turbo uses 2 turbo devises located up stream and down stream the exhaust gas flow. The upstream turbo facing a higher exhaust pressure is called the high pressure turbo, the down stream unit facing a lower exhaust pressure called the low pressure turbo. The high-pressure turbo is responsible for air flow to the engine at low engine speeds, while the low-pressure turbo operates at high engine speeds. At mid-range engine speeds, both turbos work in tandem to provide charge air to the engine. The smaller high-pressure turbo is controlled by a variable geometry turbine (VGT) to ensure quick throttle response and reduce pumping losses at low engine speeds. The low-pressure turbo is controlled by a conventional waste gate valve.

The 1.6i-DTEC diesel engine complies with Euro6b emission regulation, meeting emission standards using a NOx storage catalyst (NSC) after-treatment system, continuously alternating NOx adsorption and conversion (reduction) processes.

The focus of development was set to enable a light-off of the catalyst already at low temperatures in order to sufficiently convert NOx emissions yet maintaining the conversion efficiency at high temperatures. Optimisation on ratio of precious metal amount and effective adsorption surface have been performed in order to achieve the target.
