There’s little doubt that the BMW 5-Series is one of the top rivals that Lexus has in mind with the GS sedans.
The latest 5-Series is also very tech-focused, and it handles better than the previous model.
Infiniti's M sedans, the M37 and M56, are actually its closest rivals in execution.
Compared to the GS, the M37/56 has a roomier interior but overall, an edgier, sportier driving feel, with powerful engines and electronic driving aids.
However, in the M sedans interior noise is a bigger issue than any of these rivals.
Cadillac’s CTS is a little bit smaller and more performance-focused, with excellent handling and performance, as well as a unique interior style.
The Lexus GS models also come across as more performance-oriented than the A6, lining up more closely with the 340-horsepower, V-8-powered S6, which takes on the GS 460.
But the S6 has all-wheel drive, a feature that's not available on the GS 460 (only the 350).
The Mercedes-Benz E-Class, recently redesigned, is softer and more comfort-oriented than the GS.
For the Lexus GS 450h, its leading rival is likely the Mercedes-Benz E350 BlueTec.
With a clean-diesel engine, the BlueTec gets much better fuel economy than the 450h, and it’s the more fitting choice for long-haul highway driving.

The 2011 Lexus GS sedans are fast, refined, and well-appointed; but low points include a cramped backseat and, for the 450h Hybrid, lackluster fuel economy. |
The new 2011 BMW 5-Series might be a conservative evolution in terms of styling and design, but it’s a quite radical one with regard to how BMW’s most important model drives. |
The 2011 Mercedes-Benz E-Class sedan swings to the masculine side of the pendulum and sharpens its driving appeal in the process. |
