Audi A8 Production Hybrids Next Year?

Audi A8

Ingolstadt, Automotive - More and more car manufacturers introduced the "flagship" of the hybrid format. Audi is the latest - this morning (8/24/2011) announced - will produce hybrids next year A8. The added value offered, the same engine performance with 6-cylinder model, but fuel consumption is equivalent to 4-cylinder.


Parallel combination of a driving source which is applied on the Audi A8 is a 2.0 TFSI petrol engine and electric motor that can generate power 180kW (245PS) and 480Nm of torque. Fuel consumption average below 6.4 liters per 100km (15.6 km / liter). If you rely solely on electric power, can be accelerated to maximum speed of 100 kph. However, battery energy can only be used for a distance of 3 km with a constant speed 60kpj.
The system used is a parallel hybrid, which means the petrol engine and electric motor can work together or individually. For this, Audi says the 2.0 TFSI is used in this luxury sedan should be modified in certain parts so as to produce power 155kW (211PS) and torque 350Nm@1.500- 4.200rpm. Gasoline engines are also working together with a disc-shaped electric motor that produces 40kW (54PS) and 210Nm of torque.
Performance type synchronous electric motor with a permanet magnet mounted in the space normally occupied by the "torque converter", which is in front of the 8-speed tiptronic transmission which must also be modified. For this, Audi had to use a wet clutch plates menjemuk marinated in oil pan, served to continue or terminate the cooperation with the electric motor TFSI engine.
If you just rely on petrol engines, the car can sprint from 0-100 kph in 7.7 seconds and a top speed of 23 kph. The resulting carbon dioxide emissions below 148 g / km.
3 Mode Audi offers 3 modes of operation of choice for this car.Pure electric (EV) with only an electric mengandalkanmotor.Furthermore, D controlling the gasoline engine and electric motor. While the S mode and tipronik designed for speeding driving style (sport) or just rely on the TFSI gasoline engines.
Electric energy stored in lithium-ion battery weighs 36.7 kg installed in an area protected from tabarakan, namely in the trunk. These batteries produce 1.3 kWh of energy or 40kW.
To maintain battery performance, Audi did the cooling in two ways, namely blowing air as needed. To this exhaled air from the passenger space by using a fan. Alternatively, through a separate cooling circuit that works with automatic air conditioning system.
Especially for electric motors and power electronic controllers that work as the electric motor and batteries, cooled with water.
Furthermore, the A8 is distinguished in appearance with a detailed version of the gasoline engine. A8 is fitted to the rim of radius 10 with a diameter of 18 (standard) with fan-shaped 19-inch option turbine. Paa body added badges "hybrid". Other standard features, LED headlamps and BOSE audio system.
According to Audi, because the whole body is made of aluminum with the concept of the Audi Space Frame (ASF), weighs only 231 kg or 40 percent lighter than when using steel.To maintain strength in certain parts, such as using steel pillars fixed B!
