Toyota LR engine
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.
Maximum power output is 411.5 kW (552 hp) at 8,700 rpm. Maximum torque is 480 N·m (354 ft·lb) at 6,800 rpm. The engine will rev to 9500 rpm, with 90% of its peak torque available from 3,700 rpm to 9,000 rpm. Due to the speed at which the engine revs, an LCD tachometer was fitted to the LF-A as an analog fixture allegedly could not keep up with the engine's speed of revolution.
