The LFA is one of the fastest Lexus cars ever, and that’s in part thanks to its extraordinary engine. Codenamed the 1LR-GUE, the naturally aspirated 4.8-liter V10 was co-developed by Yamaha Motor and makes an ECE-certified 552 hp and 354 lb-ft of torque. Acceleration from 0-60 mph takes a respectable 3.6 seconds, while top speed in appropriate conditions is an astounding 202 mph. Impressive as they are, the LFA’s performance specs are only half the story.
The V10 is also a technological tour de force, featuring everything from a dual VVT-i system to dual fuel injection, a dry sump lubrication system, and individual throttle bodies. It has a 72-degree angle between the cylinder banks to help improve balance. Engineers used a combination of magnesium alloy cylinder heads, forged aluminum pistons, and forged titanium connecting rods to minimize weight –- making the engine as light as a traditional V6.
Yamaha Corporation played their part, too, leveraging their musical expertise to harmonically optimize the air intake to deliver a pleasant acoustic character that nicely complements the engine’s balance and strong performance.
