Technology behind the 3.5L V6
2GR-FSE and D-4S direct injection
The 2GR-FSE is Lexus’ 3.5-liter V6 family member that uses Dual VVT-i on both camshafts to optimize valve timing for different driving conditions. The D-4S system combines direct injection with port injection to improve fuel efficiency and power across a wide RPM range. This setup helps the GS 350 achieve strong throttle response while maintaining better efficiency than a purely port-injected V6.
Performance implications
With a 306-horsepower output (roughly 277 lb-ft of torque) and the GS 350’s chassis tuning, the 2014 model is capable of confident acceleration and steady highway cruising. The engine’s design emphasizes smooth power delivery, refined sound, and reliable, durable operation typical of Lexus’ V6 offerings.
Summary
The 2014 Lexus GS 350 is powered by a 3.5-liter V6 engine (2GR-FSE) with Dual VVT-i and D-4S fuel injection, delivering about 306 horsepower and 277 lb-ft of torque in US-spec cars. This engine pairing underpins the GS 350’s blend of luxury comfort and capable performance.
