The Lexus LC offers a choice no other premium coupe does: the LC 500 with a high-performance V8 or LC 500h with a new-generation Multi Stage Hybrid powertrain. In both, the focus is driving excitement, with the LC 500h offering higher fuel efficiency associated with the world’s luxury hybrid leader.
Upon startup, exhaling through the variable Active Exhaust, the 5-liter naturally aspirated V8 issues a clarion call to driving enthusiasts. Based on the engine in the Lexus GS F an RC F high-performance models, the LC 500 version raises the output to 471 hp and 398 lb.-ft. of peak torque. The LC 500 can sprint from zero to 60 mph in less than 4.5 seconds.
It’s a well-proven performance engine, with a low-mass reciprocating assembly using lightweight forged connecting rods, along with titanium intake and exhaust valves to allow a 7,300-rpm redline. The 32-valve cylinder heads, equipped with performance-tuned Variable Valve Timing (VVT-iE), take full advantage of the engine’s low internal friction and aggressive valvetrain specs.
The D-4S injection system uses direct fuel injection that allows a high compression ratio (12.3:1), augmented by port fuel injectors to enhance low-speed response. Under acceleration, the LC 500 V8 reveals its character in a continuously rising power curve, with the 471 hp developed at 7,100 rpm and the torque peak sustained from 4,800-5,600 rpm.
The fast-revving V8 issues a stunning soundtrack amplified by a special resonance tube connecting the intake to the firewall, plus a standard Active Exhaust that rumbles and roars like a high-performance GT should.
The driver can adjust the natural exhaust sound level via the Drive Mode Select system. The V8 is a good citizen, too, switching to the Atkinson cycle to enhance fuel efficiency at cruising speeds and Otto cycle for higher performance levels when accelerating.
