Toyota UR engine

1UR-FSE

The 1UR-FSE V8 engine, introduced with the Lexus LS 460 & LS 460 L luxury sedans in 2006 has a 4.6 L (4,608 cc) displacement, which it gets from a bore and stroke of 94 mm × 83 mm (3.70 in × 3.27 in). The engine includes D4-S direct injection and dual VVT-iE producing 385 hp (287 kW; 390 PS) at 6,400 rpm and 51 kg⋅m (500 N⋅m; 369 lb⋅ft) at 4,100 rpm.

1UR-FSE undergoes X-ray inspection and a CT (computed tomography) scan to ensure minimal deformation after the die-casting process. Camshafts are hollow to minimize weight.[2]

Applications:

• 2006-2017 Lexus LS 460 & LS 460 L
• 2008-2011 Lexus GS 460
• 2009-2013 Toyota Crown Majesta

The 1UR-FE is based on the 1UR-FSE but lacks the D4-S direct injection technology. Originally used for Lexus vehicles in the Middle East, it was introduced in 2010 in other markets to replace the 2UZ-FE engine in truck and SUV applications. This engine produces 347 hp (259 kW; 352 PS) at 6,400 rpm and 46.9 kg⋅m (460 N⋅m; 339 lb⋅ft) at 4,100 rpm in the Lexus GS and LS. For the Toyota Land Cruiser and Lexus GX the engine produces 304 hp (227 kW; 308 PS) at 5,500 rpm and 44.8 kg⋅m (439 N⋅m; 324 lb⋅ft) at 3,400 rpm.

Applications:

• 2006–2017 Lexus LS 460 & LS 460 L (Middle East)
• 2005–2011 Lexus GS 460 (Middle East)
• 2009–present Lexus GX 460
• 2012–present Toyota Land Cruiser (China, Middle East and Australia)

• 2009–2019 Toyota Tundra

2UR-GSE

The 2UR-GSE is a 5.0 L; 303.2 cu in (4,969 cc) naturally aspirated V8 engine fitted to the IS F, RC F, GS F and LC 500. It is an all-alloy DOHC, 4 valves per cylinder with Yamaha-designed high-flow cylinder heads, titanium inlet valves, high-lift camshafts and dual-length intake. It has D4-S gasoline port and direct injection, Dual VVT-i with electric VVT-iE inlet camshaft actuation. Bore and stroke is 94 mm × 89.5 mm (3.70 in × 3.52 in). The engine has a redline of 7,300 rpm.

In the IS F, the engine had an 11.8:1 compression ratio and produced 310 kW (416 bhp; 421 PS) @ 6,600 rpm and 51.3 kg⋅m (371 lb⋅ft; 503 N⋅m) @ 5,200 rpm of torque.[3] In the RC F and GS F, the compression ratio was increased to 12.3:1 and output 348 kW (467 bhp; 473 PS) @ 7,100 rpm and 53.8 kg⋅m (389 lb⋅ft; 528 N⋅m) of torque at 4,800-5,600 rpm. The engine received a further increase in power to 351 kW (471 bhp; 477 PS) @ 7,100 rpm and 55.1 kg⋅m (399 lb⋅ft; 540 N⋅m) of torque at 4,800 rpm in the LC and 354 kW (475 bhp; 481 PS) @ 7,100 rpm and 54.6 kg⋅m (395 lb⋅ft; 535 N⋅m) of torque at 4,800 rpm in the 2019 RC F.[4][5] Although since 2018, the RC F received a power decrease to 341 kW (457 bhp; 464 PS) in European markets.

Applications:

2UR-FSE

The 2UR-FSE is a 5.0 L (4,969 cc) engine which previously powered the Lexus LS600h and the current Toyota Century. It has D4-S gasoline direct injection, Dual VVT-i, and VVT-iE on the intake cam. It has the same bore and stroke as the 2UR-GSE, but produces 394 hp (294 kW; 399 PS) at 6,400 rpm and 53 kg⋅m (520 N⋅m; 383 lb⋅ft) at 4,000 rpm. The electric motors (Lexus Hybrid Drive) in the system add extra power into the drivetrain, allowing the combination to deliver 327 kW (439 hp; 445 PS) in total.

The engine's valve covers are made from a magnesium alloy, the cylinder heads are manufactured from aluminum alloy, while like the 1UR engine block it is die-cast to save weight.[6]

Applications:

• 2007-2017 Lexus LS 600h & LS 600h L (UVF45/UVF46)
• 2018-present Toyota Century (UWG60)

The 3UR-FE is a 5.7 litres (5,663 cc) engine designed for use in Toyota Tundra/Sequoia/Land Cruiser, and Lexus LX570 vehicles, without the D-4S gasoline direct injection but with Dual VVT-i. Bore and stroke of 94 mm × 102 mm (3.70 in × 4.02 in), it produces 381 hp (284 kW; 386 PS) at 5,600 rpm and 55.4 kg⋅m (401 lb⋅ft; 543 N⋅m) of torque at 3,600 rpm. A stainless steel exhaust manifold incorporating a 3-way catalytic converter is used. This engine is cast at Toyota's Bodine Aluminum and currently assembled at Toyota Motor Manufacturing Alabama. Over 1.3 million kilometers of durability testing have gone into the engine. E85 ethanol capability was optional for the 2009 model year.[7] The engine's service weight is 222 kg (489 lb).

For a time, Toyota offered an available bolt-on Toyota Racing Development Eaton's Twin Vortices Series roots-type supercharger kit for the Tundra and Sequoia bumps power up to 504 hp (376 kW; 511 PS) and 550 lb⋅ft (746 N⋅m) of torque. Offered by Toyota's TRD, the supercharger kit could be installed by dealers and covered under warranty. Later on, Magnuson offered an improved version of the supercharger kit which raised the output to 550hp.
