Technology, tuning, and how it fits the lineup
Beyond base numbers, the GS F’s powerplant uses Lexus’ advanced injection and valvetrain technology to maximize performance. The D-4S system blends port and direct injection for optimized combustion across engine speeds, while the aluminum block and heads help keep weight down for improved handling and response. The GS F pairs this engine with an eight-speed automatic transmission driving rear-wheel power, a combination engineered to deliver rapid acceleration and a connected driving experience.
Relation to the RC F and broader engine family
The 2UR-GSE is shared with the RC F, representing Lexus’ approach to delivering high-revving, naturally aspirated V8 power across its performance models. While tuned slightly differently for the GS F’s chassis and exhaust setup, the engine remains a core element of Lexus’ V8 performance strategy in the early-to-mid 2010s.
What this means for enthusiasts
For driving enthusiasts, the GS F’s motor offers a distinctive character: a strong, linear power delivery with a high-rev soundtrack that reflects a pure, naturally aspirated V8 ethos—distinct from turbocharged rivals and tuned for exhilarating on-road and track-driven experiences.
Summary
The Lexus GS F is powered by a 5.0-liter naturally aspirated V8, the 2UR-GSE, delivering 467 horsepower and about 389 lb-ft of torque. With advanced injection technology, lightweight aluminum construction, and a performance-tuned delivery, the GS F emphasizes high-revving excitement and engaging driving dynamics within Lexus’ performance lineup.
