Both new engines form part of a new generation of engines from the Kappa family and include a new 1.0-litre three-cylinder unit that will debut in the new i20 in 2015. The 998 cc three-cylinder unit is based on the established Kappa 1.0-litre MPI engine, with various enhancements and new technologies, including direct petrol injection and a small, single-scroll turbocharger.

The 1.0 litre T-GDI engine, which was developed at Hyundai's European Technical Centre in Rüsselsheim, Germany, is able to produce up to 120PS and 172Nm of torque. Features include an electronically controlled waste-gate to optimise flow and improve low-end torque and throttle response.

The 1.0-litre is joined by a newly developed 1.4-litre T-GDI engine to be showcased in the i30 CNG concept car. This newly developed 1352 cc four-cylinder turbocharged petrol engine is 14kg lighter than its predecessor, the Gamma 1.4-litre engine and also brings greater efficiency and power through a high-pressure single-scroll turbocharger integrated within the exhaust manifold, giving improved throttle response time and low-end torque along with better fuel 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 117PS in CNG mode, delivering 206Nm of torque with CO2 emissions of 87g/km.

In addition, Hyundai has premiered its first seven-speed dual-clutch transmission (7DCT), fitted into the i30 CNG concept car. It marks the first time that Hyundai has presented a dual-clutch transmission with seven gears, combining the benefits of both automatic and manual transmissions. The 7DCT provides an improvement in fuel consumption and CO2 emission compared to a conventional six-gear automatic transmission, while acceleration performance also improves.
