What engine is in Honda Insight?
Engine history by generation
Here's a concise look at the engines used in each generation of the Insight, from the original model through the current version.
- First generation (1999–2006): 1.0-liter three-cylinder gasoline engine, paired with Honda’s IMA (Integrated Motor Assist) hybrid system.
- Second generation (2010–2014): 1.3-liter inline-four i-VTEC engine with Atkinson-cycle operation, paired with IMA hybrid system.
- Third generation (2019–present): 1.5-liter inline-four Atkinson-cycle engine, paired with Honda’s i-MMD two-motor hybrid system delivering a combined output around 151 hp.
In summary, the Insight has consistently used small-displacement engines paired with a hybrid system, evolving from an early IMA setup to a more capable two-motor hybrid in the latest generation.
Current technical details
The most recent Insight uses a 1.5-liter Atkinson-cycle engine with a two-motor hybrid system (i-MMD). The engine provides modest output on its own, while the electric motors deliver the bulk of drive power, yielding about 151 horsepower combined and delivering strong fuel efficiency for a compact sedan.
Why the Atkinson cycle matters
Atkinson-cycle operation improves fuel economy by using longer intake durations and lower pumping losses. In a hybrid, electric motors can supply additional power when needed, offsetting the lower peak output of the engine.
Market variations and notes
Engine specifications can vary slightly by trim and region. For exact horsepower, torque, and fuel-economy data for your model year and market, consult the official Honda specification sheets or dealer materials.
Summary
The Honda Insight has evolved across generations: from a 1.0-liter three-cylinder IMA setup to a 1.3-liter i-VTEC Atkinson-cycle with IMA, and now a 1.5-liter Atkinson-cycle engine paired with a two-motor hybrid system (i-MMD) delivering roughly 151 hp combined. This evolution mirrors Honda’s continued emphasis on efficiency and hybrid technology in a compact sedan package.
