Almost two years ago, at the beginning of October 2014, Kia presented its ecological commitment with a prototype called Kia Optima T-Hybrid Concept at the Paris Auto Salon. This car was the vehicle of the brand South Korean more striking in that event, and not by aesthetic, but by its feature mechanical.
The Kia Optima T-Hybrid Concept combined the already known motor diesel CRDi of 1,700 cm cubic with a motor electric, that received the energy through a battery of plomo-carbono to 48 volt. As in hybrids that are currently on the market, it was capable of circular only with electric motor when the power demand was reduced.
The project remained forward, indeed, still continues, but in the brand already not have so clear that is profitable launch a diesel hybrid. Restrictions in many European cities and the hardness of the normative anti-pollution increasingly hitting more and more strong cycle diesel engines, could be the causes for which Kia shelved the idea. To the above, in addition, should add the high final cost that would have a product as well.
Albert Biermann, one of them heads of development of the brand, has asserted to the average coach that is complicated justify a large investment economic in a motor diesel that would need several tweaks although split of the 1.7 CRDi. In addition, electric motors and the entire system of batteries aren’t cheap precisely, by what is making them doubt.
On the other hand, Biermann recalled having an Atkinson cycle gasoline engine, so it would have not lost investment in the electrical part, being able to use the learned techniques and work on it. This engine Atkinson, to which Biermann makes reference, is that it marks already used in the new Kia Niro that tested in a takes of contact makes some weeks.
