Hyundai Theta GDI Turbo engine

Hyundai has developed a new turbocharged gasoline direct injection version of its Theta family engine. The Theta family is essentially a derivative of the GEMA World Engine project, a joint venture between Hyundai-Kia, Chrysler and Mitsubishi. It comes in 1.8, 2.0 and 2.4 litre sizes.

Derivatives of the GEMA engine found in cars sold in Malaysia include the Kia Optima 2.0, the Naza Citra II Rondo, the Mitsubishi Lancer and the Lancer Evolution. There have already been two turbocharged applications of GEMA derivatives in the market, a 2.4 litre turbo by Chrysler and a 2.0 turbo by Mitsubishi found in the Lancer Evolution.

Hyundai claims their Theta Turbo GDI engine has a capacity for up to 286 horsepower so far. Other than gasoline direct injection, it also features continuous variable valve timing. Various states of tune will probably be available – perhaps 200hp, 240hp and 286hp versions depending on the car its installed in.
