The '''1NZ-FXP''' is a hybrid {{convert|1497|cc|L|1|abbr=on|disp=flip}} version. Bore and stroke is {{convert|75x84.7|mm|in|2|abbr=on}}. This engine is based on the third generation 1NZ-FXE engine but converted to run on [[liquefied petroleum gas]] (LPG) fuel and using the roller rockers arms valve train mechanism like the updated 1NZ-FE engine.<ref>{{Cite press release |url=https://newsroom.toyota.co.jp/en/detail/19173376 |title=Toyota Rolls Out New Model for "JPN Taxi" |publisher=Toyota|date=23 October 207}}</ref><ref>{{cite web|url=https://www.amayama.com/en/genuine-catalogs/epc/toyota-japan/jpn-taxi/NTP10/163560/engine/1302|title=Camshaft & valve for Toyota JPN Taxi, NTP10-AHXGN|website=www.amayama.com}}</ref> The engine has a high physical compression ratio of 13.0:1, but the closing of the inlet valve is delayed, for an effective compression ratio of 9.5:1.<ref>{{Cite web|url=http://media.caranddriver.com/files/toyota-prius2004-toyota-prius-specs.pdf|title=Car and Driver 2004 Toyota Prius Specs}}</ref> The net result is that the engine has a greater effective expansion than compression—making it a simulated [[Atkinson cycle]], rather than a conventional [[Otto cycle]].

The reduction in cylinder charge means reduced torque and power output, but efficiency is increased. This combination makes the 1NZ-FXP suitable for use with the [[Hybrid Synergy Drive]], where peak torque and power demands can be met by the [[electric motor]], [[Battery (electricity)|battery]] and LPG-hybrid system. Output is {{convert|74|PS|kW hp|0|abbr=on}} at 4800&nbsp;rpm with {{convert|111|Nm|lbft kg.m|0|abbr=on}} of torque at 2800–4400&nbsp;rpm. 
Peak thermal efficiency is about 37%.<ref>{{cite web |url=http://www.greencarcongress.com/2011/04/nakata-20110411.html |title=Toyota targeting thermal efficiency of more than 45% for next-generation gasoline engines for hybrids |work=Green Car Congress |accessdate=3 May 2015}}</ref> This engine is mated to P510 eCVT transmission, same as the third generation 1NZ-FXE engine.
