Hyundai showcases downsized turbocharged engines

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 (118bhp) and 127lb.ft 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 (115bhp) in CNG mode, delivering 206Nm (152lb.ft) 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.
