What is the specs of the Lexus 2.4 L Turbo engine?
The Lexus 2.4 L Turbo is a 2.4-liter turbocharged inline-four that delivers about 275 horsepower and 317 pound-feet of torque, paired with an eight-speed automatic transmission and available all-wheel drive. It powers newer Lexus crossovers such as the NX 350 and RX 350, and sits within Toyota’s Dynamic Force engine family.
In this article, we break down what the engine is, how it works, and where it appears, with up-to-date details for model years around 2021–2025 and common US-market configurations.
What it is and where it appears
The 2.4 L Turbo is a member of Toyota’s Dynamic Force family. In Lexus models, it has been adopted to replace older naturally aspirated engines in recent redesigns, most notably in the NX 350 and RX 350 lines. It uses a turbocharger paired with intercooling and a modern fuel-delivery system to optimize both performance and efficiency.
Key specs at a glance
- Displacement: 2.4 L (2,393 cc)
- Configuration: Inline-4 turbocharged
- Turbocharging: Twin-scroll turbo with intercooler
- Fuel delivery: Direct injection (with advanced control; some markets also employ variants of port injection)
- Valvetrain: DOHC, 16 valves
- Power output: 275 horsepower (206 kW)
- Torque: 317 lb-ft (430 Nm)
- Recommended fuel: Premium unleaded for maximum output; some markets allow regular with reduced performance
- Transmission: 8-speed automatic
- Drivetrain: Available front-wheel drive or all-wheel drive
In practice, the engine’s mid-range torque helps the NX 350 and RX 350 accelerate quickly in everyday driving, while the eight-speed automatic ensures smooth shifts and keeps the turbo delivering boost when needed.
Technology and efficiency
Engine architecture highlights
The 2.4 L Turbo benefits from Toyota’s Dynamic Force architecture, which emphasizes efficient combustion, variable valve timing, and precise fuel delivery. The twin-scroll turbo design aims to minimize lag and maintain steady boost across a broad RPM range, while the intercooler helps sustain performance in warmer conditions and during sustained driving.
Note on model year and market variations
Specs can vary by model year and market. Some markets may tune output slightly differently or use alternative fuel strategies. Always refer to the official brochure or dealer specification for your region to confirm exact figures.
Where it powers Lexus models
As of the mid-2020s, the 2.4 L Turbo is most closely associated with:
- Lexus NX 350 (compact crossover)
- Lexus RX 350 (mid-size crossover)
These models pair the engine with an eight-speed automatic transmission and offer either front-wheel drive or all-wheel drive, prioritizing brisk, confident acceleration along with everyday comfort and refinement.
Summary
The Lexus 2.4 L Turbo represents a modern approach to turbocharged efficiency within the brand’s lineup. With 275 hp and 317 lb-ft of torque in typical US-spec configurations, it delivers strong acceleration, smooth operation, and refined highway manners across NX 350 and RX 350 applications. Its design emphasizes a balance of performance, efficiency, and Lexus’ characteristic comfort.
