The 2017 Hyundai Sonata offered multiple engine options: a 2.4-liter inline-4, a 2.0-liter turbocharged inline-4, and a 1.6-liter turbocharged inline-4 in Eco trims. There is also a Hybrid variant that uses a 2.0-liter Atkinson-cycle engine paired with an electric motor.
Gasoline engine options
Hyundai provided several gasoline powerplants across different trims, with varying outputs and transmissions to match performance and efficiency goals.
- 2.4-liter inline-4 gasoline engine: about 185 horsepower and 178 pound-feet of torque; typically paired with a 6-speed automatic transmission.
- 2.0-liter turbocharged inline-4: about 245 horsepower and 260 pound-feet of torque; paired with a 6-speed automatic transmission.
- 1.6-liter turbocharged inline-4 (Eco trim): about 178 horsepower and 195 pound-feet of torque; mated to a 7-speed dual-clutch transmission.
These gasoline engines covered the Sonata's mainstream performance and efficiency goals, with the Eco variant emphasizing fuel economy and the 2.0T focusing on sportier acceleration.
Hybrid powertrain
The 2017 Sonata also offered a hybrid model that combines a 2.0-liter Atkinson-cycle gasoline engine with an electric motor and a battery pack. This setup is designed to improve city and highway efficiency while maintaining smooth driving for daily commuting, using a hybrid-specific configuration distinct from the gasoline-only trims.
Summary
In short, the 2017 Hyundai Sonata was offered with multiple engine choices: a 2.4L base gasoline engine, a 2.0L turbo for higher performance, a 1.6L turbo Eco variant for efficiency, and a Hybrid variant that pairs a 2.0L Atkinson-cycle engine with an electric motor. Transmission options varied by engine, with 6-speed automatics for the base and 2.0T, a 7-speed dual-clutch for the Eco, and a hybrid-specific setup. This gave buyers a range of balance between power and efficiency across the lineup.
