What kind of engine does a Lexus IS have?
The Lexus IS lineup currenty centers on three main gasoline engines: a 2.0-liter turbocharged inline-4, a 3.5-liter V6, and a 5.0-liter V8 for the high-performance variant; some markets also offer a hybrid option.
This article explains the engine options across model years and regions, including how they power the IS models, what drives them, and how performance and efficiency differ between setups.
Current gasoline engine lineup
The following drives the latest IS models in many markets. Details vary by year and region, but these are the core options you’ll typically find today.
2.0-liter turbocharged inline-4 — IS 300
Engine: 2.0L turbocharged inline-4 (8AR-FTS family). Output typically around 241 hp (180 kW) and about 350 Nm (258 lb-ft) of torque. Transmission: 8-speed automatic. Drive: Rear-wheel drive is standard, with all-wheel drive available for certain trims and markets.
3.5-liter V6 — IS 350
Engine: 3.5L naturally aspirated V6 (2GR-FKS family). Output commonly around 311 hp (232 kW) and roughly 280 lb-ft (380 Nm) of torque. Transmission: 8-speed automatic. Drive: Available in rear- or all-wheel-drive configurations depending on market.
5.0-liter V8 — IS 500
Engine: 5.0L naturally aspirated V8 (1UR-FE/F-series lineage in performance variants). Output approximately 472 hp (353 kW) and 395 lb-ft (536 Nm) of torque. Transmission: 8-speed automatic. Drive: Primarily rear-wheel drive; high-performance setup focused on straight-line and cornering dynamics.
These engine options represent the core gasoline choices in recent IS models, balancing daily usability with performance potential. Availability of all-wheel drive and specific power figures can vary by year and market.
Hybrid and legacy options by market
Beyond the contemporary gasoline lineup, certain markets have offered hybrid and legacy engines in the IS range. These options reflect Lexus’s broader approach to efficiency and regional preferences.
Hybrid option: IS 300h (Europe/Asia and select markets)
Engine: 2.5-liter inline-4 with Atkinson-cycle operation combined with an electric motor (often paired with a dedicated hybrid transmission). System output generally around 220 hp total, with a CVT-like hybrid transmission. This variant emphasizes efficiency and smoother operation rather than peak performance.
Legacy and regional diesel options
In certain markets, older IS generations offered diesel engines (for example, IS 220d with a 2.2-liter diesel). These variants have been phased out in many regions as Lexus shifted toward turbocharged petrol and hybrid powertrains, but a few markets historically maintained diesel options for a period.
Hybrid and diesel variants illustrate how the IS has been adapted for different regulatory environments and consumer preferences, though current availability varies by country and model year.
Summary
The Lexus IS today is powered mainly by three gasoline engines: a 2.0-liter turbocharged inline-4 in the IS 300, a 3.5-liter V6 in the IS 350, and a 5.0-liter V8 in the IS 500. In some markets, a hybrid version known as the IS 300h has been offered, featuring a 2.5-liter hybrid setup. Earlier generations also included diesel and turbo variants that are largely phased out in many regions. Engine choices influence performance, efficiency, and driving dynamics across the IS lineup.
