Announced in the Lexus LFA sports car, the 1LR-GUE is a 4,805 cc (4.8 L; 293.2 cu in) DOHC 4 valves per cylinder V10 engine, made from aluminum alloy, magnesium alloy and titanium alloy and is smaller than most V8s. [2]

The oil and water pumps are located at the rear of the engine and the lubrication system uses a dry sump. Titanium is used for the valves and the rocker arms have a diamond-like coating. Each cylinder has an independent, electronically controlled throttle body.

Yamaha was contracted to co-develop the 1LR-GUE. [3] The exhaust system was co-developed with Yamaha's music division. The engineers described the sound of the engine as "the roar of an Angel". [4]

Maximum power output is 560 PS (552 bhp; 412 kW) at 8,700 rpm. Maximum torque is 480 N⋅m (354 ft⋅lb) at 6,800 rpm. The engine redlines at 9000 rpm and has a fuel cut-off at 9500 rpm, with 90% of its peak torque available from 3,700 rpm to 9,000 rpm. An LCD tachometer was fitted to the LFA as an analog fixture allegedly was not responsive enough to the engine's ability to change speed. The Lexus LFA broke the world record in 2012, for the fastest production engine revving from idle to redline in 0.6 seconds. It features a single circular dial with a central tachometer with an LCD needle. When engine speed exceeds 9000 rpm, the display area turns red to alert the driver to up-shift. [5]

<span class="mw-page-title-main">VVT-i</span> Automobile variable valve timing technology

VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing gasoline engine technology manufacturer by Toyota Group and used by brands Toyota, Lexus, Scion, Daihatsu, Aston Martin, Pontiac and Lotus Cars. It was introduced in 1995 with the 2JZ-GE engine found in the JZS155 Toyota Crown and Crown Majesta. The VVT-i system replaces the previous Toyota VVT system introduced in 1991 with the five-valve per cylinder 4A-GE "Silver Top" engine found in the AE101 Corolla Levin and Sprinter Trueno. The VVT system is a 2-stage hydraulically controlled cam phasing system. VVT-i varies the timing of the intake valves by adjusting the relationship between the camshaft drive and intake camshaft. Engine oil pressure is applied to an actuator to adjust the camshaft position. Adjustments in the overlap time between the exhaust valve closing and intake valve opening result in improved engine efficiency. Variants of the system, including D4, D4-S, VVTL-i, Dual VVT-i, VVT-iE, VVT-iW and Valvematic have followed.

The GM Ecotec engine, also known by its codename L850, is a family of all-aluminium inline-four engines, displacing between 1.2 and 2.5 litres. Confusingly, the Ecotec name was also applied to both the Buick V6 Engine when used in Holden Vehicles, as well as the final DOHC derivatives of the previous GM Family II engine; the architecture was substantially re-engineered for this new Ecotec application produced since 2000. This engine family replaced the GM Family II engine, the GM 122 engine, the Saab H engine, and the Quad 4 engine. It is manufactured in multiple locations, to include Spring Hill Manufacturing, in Spring Hill, Tennessee, with engine blocks and cylinder heads cast at Saginaw Metal Casting Operations in Saginaw, Michigan.

<span class="mw-page-title-main">Toyota MZ engine</span> Reciprocating internal combustion engine

The Toyota MZ engine family is a piston V6 engine series. The MZ series has an aluminium engine block and aluminium alloy DOHC cylinder heads. The cylinders are lined with cast iron, and is of a closed deck design. The engine is a 60 degree V6 design. It uses multi-port fuel injection (MFI), four valves per cylinder, a one-piece cast camshaft and a cast aluminium intake manifold. The MZ family is a lightweight V6 engine of an all-aluminium design, using lighter weight parts than the heavier duty VZ block engines in an effort to lower production costs, decrease engine weight, and decrease reciprocating weight without sacrificing reliability. Toyota sought to enhance the drivability pattern of the engine at exactly 3000 rpm, since that was the typical engine speed for motors cruising on the highway. The result was less cylinder distortion coupled with the decreased weight of rotating assemblies, smoother operation at that engine speed, and increased engine efficiency.
