The CNG-powered Condor truck easily cleared the criteria laid out in the exhaust emission technology guidelines for compressed natural gas vehicles, which can be regarded as long-term exhaust emissions regulations for CNG vehicles. This contributed not only to a significant improvement in environmental performance but the improvements in the engine and displacement also enabled higher low-speed torque and better exhaust brake performance.
Environmental performance was secured by engine improvements: switching from a lean burn to a stoichiometric burn system and providing a threeway catalytic built-in type muffler reduced NOx to 0.5 g/kWh or less. This figure is a reduction of at least 75% of NOx over the new long-term levels that represent the world's most severe diesel vehicle exhaust emissions regulations. Since CNG vehicles emit almost no PM, the Condor's NOx/PM levels achieve those of the draft post new long term regulations. |

| Points of interest, topicality | : | ・This vehicle, the first Japanese CNG midsize truck to be certified was released in 1996.
・Its lean burn system achieves less than half the long-term targets for NOx without a catalyst.
・The current vehicle on sale (2006) combines stoichiometric combustion with a three-way catalyst to reduce this figure to one-quarter of the long-term targets.
・Nissan Diesel has been the top seller of conventional CNG trucks (including midsize vehicles) for 7 consecutive years since 1999. |
