Hyundai Motor have showcased their latest turbocharged petrol direct injected (T-GDI) engines at the Paris Motor Show 2014. Both compact turbocharged gasoline engines are meant to improve the specific output of engines, and in turn improve the efficiency and reduce the emissions. Both 1.0-litre and 1.4-litre units are part of a new generation of engines from the Kappa family. In addition, Hyundai also revealed its first seven-speed dual-clutch transmission, meant to be used on the i30 CNG concept car.
New 1.0-litre T-GDI
The smallest turbocharged petrol engine from Hyundai is slated to make its debut on the Euro Spec new generation i20 in 2015. The new Kappa 1.0-litre T-GDI is a 998 cc three-cylinder unit based on the established Kappa 1.0 litre MPI engine. The engine features various enhancements and new technologies, including direct petrol injection and a small, single-scroll turbocharger.
Developed at Hyundai’s European Technical Centre in Rüsselsheim, Germany, the new engine is capable of producing 120 PS of power and 172 Nm of torque. Expect this engine to come to India very soon on new Hyundai models.

New Kappa 1.4-litre T-GDI engine
The second engine showcased by Hyundai at the Paris Motor Show 2014 is the Kappa 1.4-litre T-GDI unit. This newly developed 1352 cc four-cylinder turbocharged petrol engine weighs only 87 kg and is 14 kg lighter than its Gamma 1.4 predecessor.
The new 1.4-litre T-GDI engine uses a high-pressure single-scroll turbocharger integrated within the exhaust manifold to improve operational efficiency. Showcased in the i30 CNG concept car displayed on Hyundai’s Paris Motor Show booth, the Kappa 1.4-litre T-GDI engine provides 117 PS in CNG mode (expect much more power for the gasoline version) , delivering 206 Nm of torque.
Seven-speed dual-clutch transmission
Hyundai also introduced the world to its first ever seven-speed dual-clutch transmission (7DCT), also showcased in the i30 CNG concept car. The 7DCT offers good efficiency with quick shifts and great performance. The Co2 emissions are also claimed to be reduced significantly with the new transmission.
The 7DCT consists of two dry clutches and an actuator for each clutch, with engine power transferred independently into the odd and even gear train, ensuring it is ready to shift into the next gear without any torque interruption. For optimized responsiveness the electric motor-driven actuator is applied, while the external damper improve the noise vibration harshness during driving.
