Audi has shown in the International Ginebra Motor Show 2013 the Audi A3 Sportback E-Tron , a vehicle with a hybrid propulsion system with a maximum power of 204 hp and a maximum torque of 350 nm.
The A3 Sportback e-tron accelerates from 0 to 100 km/h in 7.6 seconds and reaches a tip of 222 km/h. In accordance with the ECE Standard for plug -in hybrid cars, the five -door compact is formed on average with 1.5 liters of fuel at 100 km, which corresponds to a volume of CO2 emissions of 35 g/km. In exclusively electric mode, the Audi A3 Sportback e-Tron reaches a maximum speed of 130 km/Hy has an autonomy of up to 50 km.
The Audi A3 Sportback e-tron has been conceived as parallel hybrid. As a combustion engine, a modified TFSI is used that delivers 150 hp and a couple of 250 nm. The TFSI collaborates with an electric motor that yields 102 hp and 330 nm. The album -shaped electric motor is integrated into a change is six -speed new conception tronic that distributes the force between the front wheels. Both thrusters are complemented: the electric motor delivers its maximum motor torque from the beginning and up to 2,000 rpm, and the TFSI reaches its greatest drag force between 1,750 and 4,000 rpm.
As an energy accumulator, a lithium -ion battery system is used that, when occupying little space, is mounted on the ground under the rear sidewalk, a safe place to impacts. The high voltage battery, with a housing manufactured mostly in aluminum, has a capacity of 8.8 kWh. It is composed of eight modules with a total of 96 cells.
To keep the battery inside an optimal temperature margin, a liquid cooling system with its own low temperature circuit is used. This complex technology contributes decisively to improving the power and autonomy of the electrical propulsion system, even with low external temperatures.
The electronic power module of the audi A3 Sportback e-tron is in the vain motor. It is responsible for transforming the continuous current of the battery into alternating current for the electric motor. This component, with an integrated CC/CC transformer for the supply of the 12 V on -board network, is included in the same cooling circuit as the battery and the loading device.
The load connection is on the radiator grill, behind the four hoops; Like the TFSI engine, loading also incorporates the E-Tron emblem. With the 3.6 kW load device, the high voltage battery can be completely charged in about two
and a half hours. None of the relevant components of the high-voltage network of the E-TRON Sportback has a conductive connection with the rest of the vehicle. In the event that an accident occurs and the tensioners of the belts and airbags are activated, the system is automatically disconnected from the voltage.
The air conditioner has a high voltage electrical drive; An additional electrical heater completes the heating of the cabin.
Energy recovery when braking: Electrified Servofreno
The depression servofrane has an additional supply through an electric vacuum pump. The management of the hybrid system subtly overlap its work with the activity of the electric motor. Until the average range of regimes, the powerful electric motor, which
currently works as an alternator, takes care of most of the deceleration, which recovers a large amount of energy and stores it in the high voltage battery. The wheel brakes are not activated until the driver does not step on the pedal with greater force.
The Audi A3 Sportback E-Tron is able to circulate only with the combustion engine, only with the electric motor or in hybrid mode. Already in the electric mode offers a powerful acceleration, without the need to simultaneously connect the TFSI. The two engines are activated jointly only if the driver wishes (Boost), and they are temporarily deactivated (Sailing) when the accelerator's foot rises. In this way the engine braking torque is eliminated and efficiency is increased.
Through the EV key and the e-tron selection lever, the driver can choose from three different driving programs. The Group of EV characteristics (Electric Vehicle) covers the electric mode; In program D, the A3 Sportback E-Tron circulates in a particularly efficient way and in the s mode the sporting character is enhanced.
The concept of indication of the Audi A3 Sportback E-Tron provides very precise information about the state of the propulsion system. The Powermeter in the instrument table occupies the place of the Taber Revolutions and shows the global power of the system. The instrument table also incorporates an indicator of the battery charge status. The driver's information system and the MMI Navigation Plus monitor present the strength flows in the propulsion system, autonomies and consumption values in electrical and gasoline mode.
In the field of Audi Connect, the brand of the four hoops plans for its electric vehicles a whole catalog of new online services. With them, the driver will be able to activate and control comfortably from his smartphone many functions, such as load processes or complete air conditioning.
Sports Elegance: The cabin
The interior ergonomic of the A3 Sportback e-tron presents some extraordinary quality finishes. The interior has been carried out in cloud gray and sports seats have been decorated with contrasted seams. The access moldings are aluminum and incorporate the E-Tron emblem, which is also found in the knob of the change lever and in the steering wheel. The trunk offers a volume of 280 liters, which grows to approximately 1,000 liters by dejected the back of the rear seats.
Painted in a resplendent Misano, the Audi A3 Sportback e-tron makes clear its sports character. Its wheels presume the characteristic e-tron design, with 15 radios that remind the blades of a turbine. On the Singleframe grid and in the grids of the air inlets, the chrome cross-sectional bars carry undulated profiles of three-dimensional effect, another of the e-tron features. The rear skirt with the new diffuser is also typical of the design.
The A3 Sportback E-Tron gets the most out of its sporting potential in acceleration, recovery and rapid curves. This is due not only to the complex filming train, but also to the weight of the vehicle, which despite the abundant equipment remains low, especially for a plug -in hybrid. Among the standard equipment is, for example, the Xenón Plus headlights, the comfort access to the rear seats, the panoramic roof, the lighting package, the Audi Drive Select Dynamic driving system and the MMI Radio with retractable screen.
