The engine is state of the art in every — its low frictional losses, its its intercooler and its thermal management. One feature is the way the exhaust manifold is into the cylinder head. a cold start, it brings the swiftly up to operating temperature.

At high loads the water lowers the temperature of the exhaust

Thanks to the high electric of up to 50 kilometers (31.07 miles), customers will only experience the gasoline engine of the A3 Sportback e-tron in action. effect of the plug-in hybrid is that the TFSI is often activated in kickdown situations, and is subjected to high loads still cold. For that the developers have equipped it a variety of protective features.

include modified cylinder and piston rings, plus a to measure oil quality.

Developing 110 kW hp) and 250 Nm (184.39 lb-ft), the 1.4 TFSI is a unit. It supplies peak across the entire speed from 1,750 through rpm, thus harmonizing with the electric motor. The of 330 Nm (243.40 lb-ft) is available from the off, and is maintained across a broad speed up to about 2,200 rpm. Its output is 75 kW. The system output of the A3 e-tron is 150 kW (204 hp), and torque is 350 Nm (258.15 lb-ft).

the combination of electric motor and engine, an overall operating of up to 940 kilometers (584.09 miles) is And its road performance is unwaveringly It takes a mere 4.9 seconds to from 0 to 60 km/h (37.28

The electric motor is a permanently synchronous machine. It weighs 34 (74.96 lb) and is liquid-cooled via a cooling in the stator. The electric motor is between the engine’s dual-mass and the newly developed separating the K0 clutch.

When the TFSI it is tow-started by the electric motor via the As soon as the former has achieved the speed as the electric motor, the is opened. This smooth, precise process takes within half a second.

Together with the K0 separating the electric motor is integrated a newly designed six-speed e-S which transfers the power to the wheels. Like all Audi transmissions, it consists of two subsidiary that are served by the two multi-plate K1 and K2. Gears are shifted by switching the

This takes just a few of a second and happens without any interruption in propulsive power.

on the level of charge, the voltage between 280 and 390 volts. The battery of 96 prismatic cells arranged eight modules of twelve each. Including the electronic — the battery management and the battery junction box — the system weighs 125 kilograms lb).

Its housing is bolted to the floor at five points, and the shell is made from

An elaborate liquid cooling ensures that the battery is within a suitable temperature during operation. Drivers of the A3 e-tron will be able to electrically in hot summer conditions and at winter temperatures alike. cooling plates regulate the of the high-voltage battery’s eight

The cooling system represents a low-temperature circuit in the car and runs on a cooler housed in the engine If need be, it can be connected to the air conditioning and even divided into two circuits.

In the event of a crash severe to trigger the belt or airbags, the entire system is from the power supply. The battery is installed under the bench seat — an where the high-strength and ultra-high-strength components of the occupant cell an especially strong structure. Its and interior structure are equally of a sturdy design.

The 12-volt battery for the low-voltage and the 40-liter (10.57 US gallons) tank are located above the axle. Both components impinge on the trunk of the A3 Sportback — in the standard configuration it 280 liters (9.89 cubic ft) and liters (39.55 cubic ft) the rear seat backs

Audi supplies the A3 Sportback with a universal charging as standard. The customer can interchange the plugs so that the lead can be both with domestic sockets and with industrial sockets, for full charging These connecting plugs are in design, so that the A3 Sportback can be recharged anywhere in the world.

For use at home, the charging lead can be into a wall-mounted holder. this holder has an Audi and as well as being a convenient way to and use the lead, it is lockable. The charging is thus protected against even when kept

The charging lead supplies the car alternating current from the via the charging connection, which is in the grille behind the fold-out rings. As well as a status the unit includes two pushbuttons the user to choose between charging and immediate charging. In the the alternating current fed in by the charger is into direct current for the

From an industrial power it takes slightly more two hours to charge the battery From a normal domestic socket in Europe, the charging takes about three and 45 minutes. Audi is working on a joint project with a of renewable power, because driving only makes sense if such power is

Another medium-term project of is automatic charging without contacts, referred to as Audi charging. Here the charging involves an alternating magnetic between the stationary charging pad on the and the mobile charging pad in the car, to the principle used by an electric

The power electronics, located in the compartment, then convert the direct current into current for the electric motor. It has six transistors for this task. The electronics, which include a converter for connecting up the vehicle’s electrical system, are compact and in weight.

They have a volume of 8 liters (0.28 ft) and weigh 10 kilograms (22.05 Together with the charger, it is into the same cooling as the traction battery.

There are yet special components for electric The air conditioning compressor has an electric integrated into the high-voltage A thermoelectric heating element and a auxiliary heater round off the heating system.

The hybrid is configured to function in harmony the electric motor. Up to medium the electric motor, now functioning as largely handles retardation. The that it recovers is fed into the battery.

The wheel brakes become active if the driver the pedal more forcefully.

recuperation is just one of several statuses of the Audi A3 Sportback The car is almost always started even at very low temperatures, in hot conditions or when battery is very low. The electric high torque enables the compact car to accelerate away

It goes from 0 to 60 km/h mph) in 4.9 seconds — quiet but forceful propulsion.

In the mode the Audi A3 Sportback can travel at up to 130 km/h (80.78 — it could go faster, but would not be efficient. When at a constant 100 km/h (62.14 generally only the electric is active provided there is energy in the battery. As soon as the steps hard on the accelerator, for to overtake, and causes the pedal to go a certain resistance point, it the TFSI to cut in via the K0 separating clutch.

In the boost mode the Audi A3 e-tron accelerates with all of 350 Nm (258.15 lb-ft).

When the releases the accelerator at high the hybrid management enters the mode. Now both drives are deactivated and are no longer developing torque. When stepping off the at medium and low speeds, the system energy through coasting braking recuperation then active when the brake is pressed, except if a full application is needed.

The driver has ways of actively managing the response. They can choose three programs using a in the driving area and the e-S tronic lever. The EV characteristic map gives to electric drive, whereas the A3 Sportback e-tron behaves sportily in the S program. The hybrid mode can be selected via a menu in the This mode preserves the energy stored in the battery for use.

In addition, the driver can detailed settings in the Audi select control system. stages of coasting recuperation are assigned to the individual Audi select modes. Within ranges, this enables the to influence how the battery is charged on the move.

The Audi A3 Sportback displays supply precise about the driveline status. The in the instrument cluster shows the overall output, as well as the of the driveline and the battery charge. The for the MMI navigation plus shows the flows in the hybrid system.

In the driver information system the operating ranges and consumption for electricity and gasoline.

Under the connect umbrella Audi is developing an entire portfolio of online services for the A3 Sportback Drivers can use these to monitor and a wide range of functions via iOS or android smartphone or via a web portal.

The driver can call up the car’s — such as the battery’s charge status, the electric or its current parked location. can program charging schemes from their mobile or computer. They have the of starting and stopping charging or the charging timer and climate scheme to reflect when next plan to drive the

They can thus specify in at what time on what they want to drive off the battery fully charged.

The control planner, the third works similarly. The owner of an A3 Sportback e-tron can for instance a target temperature for the interior to a differentiated timetable. Adjusting the in advance while still to the power socket is much efficient than when electrically, because it does not constitute a drain on the car battery and optimizes the electric range. In it also adjusts the drive to the appropriate temperature for the conditions.

the web portal gives the owner the to check their trip e.g. power consumption, driven and speed.
