The 2007 Hyundai Sonata offered two gasoline engine options: a 2.4-liter inline-four and a 3.3-liter V6.
This article explains the engines used in the 2007 Sonata, how they’re configured, and the typical performance figures associated with each, noting which trims and markets received which option.
Engine options and configurations
2.4-liter inline-four
Before listing the key specifications, here is a concise snapshot of the base engine available in many US-spec 2007 Sonatas.
- Displacement: 2.4 L
- Configuration: inline-4
- Valvetrain: DOHC, 16 valves
- Horsepower: approximately 162 hp
- Torque: approximately 164 lb-ft
- Fuel system: multi-point fuel injection
These figures describe a power-efficient option that balanced everyday driving with reasonable performance. The 2.4-liter engine was the more common choice for most trims and emphasized fuel economy alongside adequate acceleration.
3.3-liter V6
Below are the core specifications for the available V6 option that delivered stronger performance.
- Displacement: 3.3 L
- Configuration: V6
- Valvetrain: DOHC, 24 valves
- Horsepower: about 235 hp
- Torque: about 226 lb-ft
- Fuel system: multi-point fuel injection
The 3.3-liter V6 provided notably quicker acceleration and highway merging capability, at the cost of lower fuel economy compared with the four-cylinder option.
General notes on availability
In the United States, the two-engine setup was offered across different trims, with the four-cylinder serving as the standard, efficiency-focused choice and the V6 available as a more performance-oriented option on higher trims. Transmission choices typically included a four-speed automatic on most US-market models.
Summary
The 2007 Hyundai Sonata could be powered by either a 2.4-liter inline-four or a 3.3-liter V6. The four-cylinder engine delivered around 162 horsepower and 164 lb-ft of torque for better fuel economy, while the 3.3-liter V6 produced about 235 horsepower and 226 lb-ft of torque for stronger performance. Both engines were paired with Hyundai’s multi-point fuel injection systems and DOHC valvetrains, with transmission setups commonly featuring a four-speed automatic in the US market.
