Hyundai has recently held its International Conference of Motors, where he has released two of the new features that will be part of the catalog of engines and transmissions in the immediate future of the brand. The koreans have presented a new 1.6 GDi of his family Kappa especially developed for adapt to mechanical hybrid, as well as a new gearbox eight-speed automatic.
engine 1.6 GDi will be the heart, coupled to an electric motor in future hybrid and plug-in hybrids from Hyundai. Currently the brand was already selling this type of vehicles in other markets, but this new engine is more appropriate for Europe. will make his Debut in a first model at the beginning of 2016 and among its peculiarities are its operating cycle Atkinson, EGR cooling and a longer stroke which optimizes the thermal efficiency of the engine.
The new engine also has a system of management of the temperature independent for the cylinder head and block, keeping the first few 105ºC and the cylinder head to 88ºC. This accelerates the heating of the block to reduce friction and keeps the cylinder head at a lower temperature to eliminate the tendency to detonation and improve fuel economy. In this way Hyundai manages to markedly improve the thermal efficiency, up to 40% (from 30% of a conventional engine). This propellant eroga 105 horsepower and 147 Nm of torque that will be supplemented by an electric motor. Still do not know the definitive specification of the new hybrid systems, and plug-in hybrids.
The new gearbox eight-speed automatic will be the most advanced powertrain of Hyundai until the time, leading to a fuel saving of 7.3% with regard to the current boxes of six-speed. Will get a better response from the engine due to a staggering optimal speed and a quick transition between the same. This transmission is due for release in the models larger and more powerful of the signature. With respect to the case of the six-speed has been managed to reduce the loudness, and vibration, in addition to saving 3.5 kilos of weight.
