About the 2018 Lexus GS

4th generation GS (2012-2020), after the 2016 refresh, late-cycle year.

Lexus positions the GS as a midsize luxury sport sedan with fewer compromises than softer luxury sedans or harsher German sport sedans. The core pitch is rear-drive balance, a quiet and well-finished cabin, strong reliability, and multiple personalities: efficient turbo four-cylinder, stronger V6, quick hybrid, or full GS F performance. For most buyers, the GS is the Lexus sedan for drivers who want sharper handling than an ES without giving up comfort and daily usability.

The GS 300 serves as the entry model, pairing a 241-hp turbocharged engine with rear-wheel drive, a 12.3-inch navigation display, and a standard safety suite. The GS 350 brings a stronger 311-hp V6 and either rear- or all-wheel drive, while the GS 450h combines its gas engine and electric motors for 338 hp. At the top, the GS F is the dedicated performance model with a 467-hp V8, upgraded brakes, and handling hardware designed to make it feel sharper in corners.
