Kia/Hyundai 2.0 L Engines
The Hyundai 2.0L (Theta) is a 4-cylinder inline piston engine, designed specifically for cars from the Hyundai Motor Company.
The base engine consists of:
- Al all-aluminum engine block and cylinder head
- Dual Overhead Camshafts (DOHC) with a timing chain
- Continuously Variable Valve Timing (CVVT) on the intake side
- Continuously Variable Valve Timing (CVVT) on the exhaust side
(Theta II only) - Sequential multi-port fuel injection or direct injection
(Theta II Turbo only)
The engine specifications include:
- A displacement of 122 cubic inches (1,998 cubic centimeters)
- 3.4 in x 3.4 in (86 mm x 86 mm) cylinder bore and piston stroke
- 10.5:1 compression ratio (9.5:1 on the Theta II Turbo)
- Theta: 142 to 149 horsepower (106 to 111 kW) at 6,000 rpm
- Theta II: 163 horsepower (121 kW) at 6,200 rpm
- Theta II Turbo: 240 to 274 horsepower (192 to 204 kW) at 6,000 rpm
- Theta: 138 to 143 lb-ft (187 to 194 Nm) of torque at 4,000 to 4,250 rpm
- Theta II: 145 to 146 lb-ft (197 to 198 Nm) of torque at 4,500 to 4,600 rpm
- Theta II Turbo: 269 lb-ft (365 Nm) of torque at 1,750 to 4,500 rpm
The Hyundai 2.0L first debuted in the fifth-generation Sonata in 2004, initially in South Korea, before making its debut in North America a year later. It was then used in the second-generation Kia Optima and Carens.
In 2007, Hyundai introduced a new generation of the 2.0L (Theta II), which added CVVT on the exhaust side, as well as increased horsepower and torque. This engine was used in the Hyundai Sonata and Tucson, and the Kia Optima, Forte, and Sportage.
A turbo variant of the 2.0L (Theta II Turbo or 2.0T) was also produced, which changed the CVVT controls from hydraulic to electronic, and increased the horsepower and torque yet again. This engine was used in many Hyundai applications, including the Genesis, Sonata, Santa Fe, and more recently, the Elantra N and Kona N—it was also used in the Kia Optima, Sorento, and Sportage.
Unlike the previous iterations however, the 2.0T has been subject to recalls due to engine failures caused by initial manufacturing problems, but thanks to remanufacturing, the engine is now more reliable than ever before.
Overall, the Hyundai 2.0L delivers a good balance of performance and fuel efficiency.
