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.
Keeping with traditional practice for high-performance Toyota engines, Yamaha was contracted to co-develop the 1LR-GUE.
Maximum power output is 412 kW (560 PS) 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. The engine revs from idle to its 9500 rpm redline so quickly, that this is the reason the LFA does not have an analog gauge cluster, due to the inability for an analog gauge to keep pace with how quickly this engine revs.
