Engine/Transmission/Drivetrain/Performance
The Lexus LS 460 models deliver the luxury of powerful, smooth performance from a 4.6-liter V8 teamed with an eight-speed automatic transmission. The engine produces 380 horsepower and 367 lb.-ft. of peak torque in rear-wheel-drive configuration; 357 horsepower and 344 lb.-ft. of torque with all-wheel drive (AWD).
The Lexus V8's superior performance is due in large part to innovative technologies, including the world's first electric motor-driven Variable Valve Timing with intelligence and Electronically (VVT-iE) controlled intake cam. The electrically controlled intake achieves superior engine-startup operation and high-output performance.
A dual fuel-injection system, with both port and direct injection, optimizes efficiency under all conditions. The direct injection helps provide cylinder cooling that allows the high compression ratio (11.8:1) needed to produce such high power cleanly and efficiently. The dual-tract intake system and an Acoustic Control Induction System (ACIS) contribute to the smooth, linear power delivery.
The Lexus eight-speed automatic transmission allows gear ratios that maximize torque up to the tire-grip limitations in the lower ranges yet maintains quietness and admirable fuel efficiency at higher speeds. The Lexus LS 460 can accelerate from zero-to-60 mph in about 5.4 seconds; 5.9 seconds for the all-wheel drive models.
Even with that level of performance, the Lexus LS 460 achieves an EPA-estimated 16 mpg city and 24 mpg highway rating (AWD is 16 city/23 highway) and meets Ultra-Low Emissions Vehicle II (ULEV II) certification. A new ECO drive indicator helps encourage economical driving.
The AWD versions of the Lexus LS 460 and Lexus LS 460 L utilize a drivetrain almost identical to their hybrid counterpart, the Lexus LS 600h L. The AWD system features a highly compact center TORSEN® limited-slip differential that distributes drive torque between the front and rear wheels. In normal driving conditions, the front and rear torque distribution ratio is set at a rear-bias 40:60, which aids agility. The system can instantly and optimally vary torque distribution between 30:70 and 50:50, depending on driving conditions, thus helping to ensure excellent traction performance and driving stability.
The AWD models also have standard 18-inch wheels with all-season tires, and a wood and leather-trimmed heated steering wheel for added luxury. All models offer the Cold Weather Package that includes a windshield deicer, upgraded battery, and more effective heater core.
