The {{convert|{{engine size|bore=87.5|stroke=82.5|cyl=8|scale=1000}}|cc|L cc CID|1|abbr=on|order=out}} all-alloy '''1UZ-FE''' debuted in 1989 in the first generation [[Lexus LS|Lexus LS 400]]/[[Toyota Celsior]] and the engine was progressively released across a number of other models in the Toyota/Lexus range. The engine is [[Stroke ratio#Oversquare|oversquare]] by design, with a bore and stroke size of {{convert|87.5x82.5|mm|in|2|abbr=on}}.<ref name=uzguide/> It has proven to be a strong, reliable and smooth powerplant with features such as 6-bolt main bearings and belt-driven quad-camshafts. The water pump is also driven by the timing/cam belt. The [[connecting rod]]s and [[crankshaft]] are constructed of steel. The pistons are [[Hypereutectic piston|hypereutectic]].

The [[#FV2400-2TC|FV2400-2TC]] derivative is one of the few road-going engines that is [[Federal Aviation Administration|FAA]] approved for use in an airplane.

Its resemblance to a race engine platform (6 bolt cross mains and over square configuration) was confirmed in 2007 by David Currier (in an interview with v-eight.com), vice president of TRD USA, stating that the 1UZ platform was based on CART/IRL engine design. It was planned to be used on GT500 vehicles, however its subsequent use in the Daytona Prototype use had not been planned.{{cn|reason=Exact URL required instead of a vague v-eight.com|date=February 2023}}

In its original, Japanese domestic market trim with 10.0:1 compression, power output is {{cvt|191|kW|hp PS|0|adj=mid|JIS}}, torque of {{Convert|353|Nm|lbft|0|abbr=on}}.<ref name=uzguide/> The European-market version produces a claimed {{cvt|245|PS|kW hp|0|adj=mid|DIN}}.

The engine was slightly revised in 1995 with lighter connecting rods and pistons and an increased compression ratio to 10.4:1 resulting in peak power of {{Convert|195|kW|hp PS|0|abbr=on}} at 5,400&nbsp;rpm and torque of {{convert|365|Nm|lbft|0|abbr=on}} at 4,400&nbsp;rpm.

In 1997, Toyota's [[VVT-i|VVT-i variable valve timing technology]] was introduced along with a further compression ratio increase to 10.5:1,<ref name=uzguide/> bumping power and torque to {{convert|216|kW|hp PS|0|abbr=on}} at 5,900&nbsp;rpm and {{convert|407|Nm|lbft|0|abbr=on}} at 4,100&nbsp;rpm. For the GS 400, output was rated at {{convert|224|kW|hp PS|0|abbr=on}} at 6,000&nbsp;rpm and {{convert|420|Nm|0|abbr=on}} at 4,000&nbsp;rpm.

The 1UZ-FE was voted to the [[Ward's 10 Best Engines]] list for 1998 through 2000.<ref>{{cite web|url=http://findarticles.com/p/articles/mi_m3165/is_n1_v34/ai_20228268/pg_7 |title=Revved up!
