The N series comprises small displacement, inline-four diesel units designed for compact passenger vehicles.
==1N== The 1N is a {{convert|1.5|L|cc|0|abbr=on}} inline-four diesel engine. It utilizes a single overhead camshaft (SOHC) configuration with two valves per cylinder.
The engine's internal dimensions feature a bore of {{convert|74|mm|in|abbr=on}} and a stroke of {{convert|84.5|mm|in|abbr=on}}, resulting in a compression ratio of 22:1. In terms of performance, the naturally aspirated 1N produces a peak power output of {{convert|55|PS|kW hp|0|abbr=on}} at 5,200 rpm. Torque output ranges from {{convert|9.1|kgm|Nm lbft|0|abbr=on}} to {{convert|9.3|kgm|Nm lbft|0|abbr=on}}, depending on the specific vehicle application.

==1N-T== The 1N-T is the turbocharged variant of the 1.5 L diesel engine. While sharing the same bore and stroke (74 mm and 84.5 mm) and 22:1 compression ratio as the standard 1N, the addition of forced induction increases performance significantly.
The 1N-T generates a peak power output of {{convert|67|PS|kW hp|0|abbr=on}}. Torque is also improved, ranging between {{convert|13.3|kgm|Nm lbft|0|abbr=on}} and {{convert|14.0|kgm|Nm lbft|0|abbr=on}}, providing greater pulling power for the vehicles it powers.
