Superb performance, fuel-efficient engine and electric motor with a top speed of 100 km / h ensures Kia Optima Hybrid high ranking among the hybrids, but what ensures its success with customers is primarily its very modern and attractive appearance to the outside and inside.
Kia Motors Corporation is still in the saloon car in Los Angeles unveiled a new Kia Optima sedan Hybrid. The model, which is basically designed for the North American market, a thorough transformation of the model Optima / Magentis, especially in design and engine performance. Optima Hybrid, which comes across the water in the spring, will be Kia's first hybrid on the most important market for Kia.
Kia Optima Hybrid boasts a very good motor performance, with acceleration from 0-100 km / h in 9.2 seconds and a top speed of 195 km / h. The biggest shift has been made on fuel consumption, because it is a hybrid of 41% more economical than the usual Optima with a 2.4-liter DOHC petrol engine. Optima Hybrid is equipped with simple parallel hybrid system, because gasoline engine works in conjunction with a small electric motor and a drive to the front pair of wheels, a transmission is in charge šesterobrzinski automatic transmission.
Special hydraulic clutch, which is located between the crankshaft of engine and transmission, allows the gasoline engine off so that Optima may act only with the electric motor, for example, to a maximum of 100 km / h and of course no emissions of CO2.
Europe without Optima Hybrid
In Europe, Kia's limousine in the standard version with 1.7 VGT diesel engine developing 136 horsepower, manual transmission šesterobrzinskim and CO2 emissions of 113 g / km in early summer 2011. year, while information about the arrival of hybrids so far yet. 2.0-liter and gasoline powered sedan with 170 hp is expected in late 2011.
Automatic and seamless operation for the driver
The hybrid is basically operating in the so-called. power module. Speeding vehicles, thanks to a special generator (HSG - Hybrid Engine Starter / Generator) activates the gasoline engine. The electric motor can act as a spare engine (when accelerating uphill and attendance) as a generator, to fill the batteries when necessary. For shorter or longer stopping action engine in idle, the gas engine automatically shuts down, which also contributes to reducing CO2 emissions. During braking, the electric motor converts kinetic energy into electricity and to store it. 8.5-kilovatni HSG generator acts as a generator to recharge the battery while the vehicle is stopped and the system recognizes that the battery is almost empty.
Effect of hybrids in all driving conditions automatically and quite seamlessly, for both driver and passengers. 30-kilovatni motor boasts a maximum power of 41 bhp and 205 Nm of torque in the range between 0 and 1,400 rpm in electric mode, in combination with a gasoline engine produces 209 hp and a torque of 265 Nm. Kia Optima Hybrid boasts the fact that the only car in the world of electric motors used for cooling oil.
Hybrid for their work uses a lithium-polymer batteries that Koreans have developed in collaboration with world-renowned Korean manufacturer LG Chem. In addition to the lithium-polymer batteries better than lithium-ion (we use them in portable computers and mobile phones), are more durable and easier to store and are ideal for use in vehicles.
A new generation battery provides an optimal balance between performance, energy density, and temperature stability. Age of the battery is at least 10 years or 150,000 miles (about 240,000 km). A new generation of batteries can also boast a smaller mass, because with 43.6 kg and the low volume does not take up too much valuable luggage space.
Revised Theta petrol engine
The famous 2.4-liter
gasoline engine is tuned for the hybrids, among other things, for as much as 20% increased compression ratio, which affects the reduction of CO2 emissions and fuel consumption (10% compared to ordinary Theta engine). Šesterobrzinski automatic transmission from the ordinary performance of adapted hybrids. Torque converter was replaced by an electric motor with a highly efficient oil pump. This allows the transmission of action that increases the recovery of kinetic energy generated during braking and provides odazivnije action in relation to the CVT gearbox.

The creators of the Optima a lot of attention are intended aerodynamics of vehicles, especially the front, so it is a hybrid version of the usually lower by 5 mm, and furthermore enhanced by placing a friction wheel tire with less friction. The result is a drag coefficient Cd of only 0.26. Energy-saving solutions, which have found their place in the new Optima are next called. regenerative braking system of charging more and electric power steering (instead of hydraulic) and an electric air compressor, which allows a very efficient operation of air conditioners.
Unlike the single hybrid drive new Optima is the other equipment intended for the comfort and convenience no different than his usual performances, it offers an identical standard and optional equipment. Outside Optima Hybrid characterized by two chromed exhaust pipes, tinted glass, turn signals integrated into outside mirrors and 16-inch alloy wheels with 205/65 R16 tires. As options are also available 17-inch wheels with tires measuring 215/55 R17.
Inside, the driver in the center console, first saw "ECO guide" that teaches drivers about eco-driving. Review and modern designed instruments offer the driver a sense of premium sports, without renouncing to comfort and spaciousness. Of course, the engineers did not forget the other high-tech gadgets that fall into this class of cars.
Kia is the best car form me. Speciale I like the KIA CAR. It's beautibully.
