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 400/Toyota Celsior and the engine was progressively released across a number of other models in the Toyota/Lexus range. The engine is oversquare by design, with a bore and stroke size of {{convert|87.5x82.5|mm|in|2|abbr=on}}. 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 rods and crankshaft are constructed of steel. The pistons are hypereutectic.

The FV2400-2TC derivative is one of the few road-going engines that is 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}}. 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 rpm and torque of {{convert|365|Nm|lbft|0|abbr=on}} at 4,400 rpm.

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

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

The 2UZ-FE was a {{convert|4663|cc|L CID|1|abbr=on|disp=flip}} version built in Tahara, Aichi, Japan and at Toyota Motor Manufacturing Alabama. Unlike its other UZ counterparts, this version uses a cast iron block to increase durability, as it was designed for low-revving, high-torque pickup and SUV applications. Its bore and stroke is {{convert|94x84|mm|in|2|abbr=on}}. Output varies by implementation, but one VVT-i variant produces {{convert|202|kW|hp PS|0|abbr=on}} at 4800 rpm with {{convert|427|Nm|lbft|0|abbr=on}} of torque at 3400 rpm. JDM versions produce {{convert|173|kW|hp PS|0|abbr=on}} at 4800 rpm and {{convert|422|Nm|lbft|0|abbr=on}} at 3600 rpm, while Australian models produce {{convert|170|kW|hp PS|0|abbr=on}} at 4800 rpm and {{convert|410|Nm|0|abbr=on}} at 3600 rpm.

Like the 1UZ-FE, it has aluminum DOHC cylinder heads, multi-port fuel injection, 4 valves per cylinder with bucket tappets, one-piece cast camshafts, and a cast aluminum intake manifold. For 2010, it was replaced by the 1UR-FE or 3UR-FE, depending on the country.

In 1997, the US Federal Aviation Administration granted production certification for the FV2400-2TC, a twin-turbocharged airplane powerplant based on the 1UZ-FE. The {{convert|360|hp|kW PS|0|abbr=on}} FV2400 was developed in partnership with Hamilton Standard, which provided the digital engine-control system.{{cite news |url=https://www.flightglobal.com/news/articles/toyota-is-cleared-to-produce-piston-aero-engine-1327/ |title=Toyota is cleared to produce piston aero-engine |date=1997-01-08 |access-date=2017-09-20 |via=Flight Global}} The goal was to produce a four-seat propeller aircraft.{{cite news |url=https://www.nytimes.com/1996/12/20/business/look-up-in-the-air-it-may-be-a-toyota.html |title=Look, Up in the Air, It May Be a Toyota |work=The New York Times |date=1996-12-20 |access-date=2017-09-20}}

In 1998, a marine derivative of the UZ powerplant was produced for boating applications. The 4.0 L VT300i engine, producing {{cvt|300|hp|kW PS|order=flip|0}} at 6000 rpm and {{cvt|310|lbft|Nm|order=flip|0}} at 4200 rpm, used the same block as the UZ engine on the Lexus SC 400, GS 400, and LS 400.
