2009 Lexus GS460

The 2009 Lexus GS460 is a luxury sedan offering a blend of performance and refinement. It was the top-of-the-line GS model, featuring a powerful 4.6L V8 engine producing 342 horsepower and 339 lb-ft of torque. Other engine options in the GS range that year included the 3.5L V6 (GS350) and the hybrid 3.5L V6 (GS450h). The GS460, along with the GS350 RWD, came equipped with an 8-speed automatic transmission, while the GS350 AWD and GS450h used a 6-speed CVT respectively.

Common criticisms often revolve around its somewhat dated styling compared to newer rivals and fuel economy that is lower than the V6 options.
