What engine does the GS 460 have?

The Lexus GS 460 is powered by a 4.6-liter V8 engine, the 1UR-FSE direct-injected unit, delivering about 342 horsepower and 339 pound-feet of torque.


Produced as part of the second-generation GS lineup, the 1UR-FSE is a 4.6-liter V8 with direct injection and dual overhead cams. It is paired with an 8-speed automatic transmission and was offered in various markets roughly between 2007 and 2011, providing smooth, refined power for a luxury sedan rather than a high-revving sports profile.

Which Lexus GS has a 2JZ?


The Lexus GS 300 from 1998 to 2005, which is the second generation of the GS, has the naturally aspirated 2JZ-GE engine. The more powerful, turbocharged 2JZ-GTE engine was never offered in a U.S. production GS, though it can be found in Japanese market Toyota Aristo models and is a popular engine swap for the GS 300.
 

  • GS 300 (1998-2005): Came with the 2JZ-GE engine, a 3.0L inline-six that is naturally aspirated, reliable, and has a strong aftermarket for modifications. 
  • Turbocharged 2JZ-GTE: This is the turbocharged version made famous in the MK4 Supra and is not a factory option in the U.S. GS models. 
  • Engine swaps: Enthusiasts frequently swap the 2JZ-GTE engine from the Toyota Aristo into the GS 300 due to the 2JZ-GE's strong block and the availability of the turbo variant.

What years to avoid GX 460?


The main Lexus GX 460 years to avoid are 2010–2013 due to potential issues like engine oil leaks (valley plate leak), as well as the 2010 model specifically, which had a temporary sales suspension after a rollover risk was identified during sharp turns. Later models, especially 2016 and 2017, may be more prone to oil leaks as well, though not as critically as the earlier years. 
Years to be cautious about

  • 2010–2013: These early models are more frequently cited for potential problems, such as the valley plate coolant leak, which can be expensive to repair. 
  • 2016 and 2017: These years have been noted by some owners as having a higher likelihood of oil leaks. 

Model years generally considered more reliable 
  • 2014 and later: These models reportedly have a different, less leak-prone head gasket. 
  • 2021 and 2022: These years are specifically highlighted as being very reliable. 

Other potential issues to consider with any model year
  • Secondary Air Injection System: Problems with this system can be costly to repair. 
  • Suspension: Models with the optional AHC (Adjustable Height Control) or KDSS (Kinetic Dynamic Suspension System) can experience issues, though Lexus has issued a TSB (Technical Service Bulletin) to address a leaning issue in some earlier KDSS vehicles. 
  • Rust: In areas where roads are salted, rust can be a concern, especially on models driven in the North. 
  • Maintenance: Regular and consistent fluid changes, especially transmission fluid, are crucial to the longevity of the vehicle.
