The Audi A3 Sportback e-tron

Posted on 10. Sep, 2013 by in Audi Canada

From 0 to 100 km/h (62.14 mph) in 7.6 seconds and a tip speed of 222 km/h (137.94 mph) – a Audi A3 Sportback e-tron adds an additional prominence to a sporty impression of a compress reward automobile line. In suitability with a ECE customary for plug-in hybrid vehicles, a normal CO2 emissions are a small 35 grams per km (56.33 g/mile) – homogeneous to expenditure of 1.5 liters of fuel per 100 kilo-meters (156.81 US mpg).

Thanks to a ultra lightweight construction truth of Audi, a unladen five-door indication finish with all electrical components weighs reduction than 1,580 kilo-grams (3,483.30 lb), with space for 5 occupants and copiousness of cargo. It comes finish with all a brand’s strengths – superb design, sporty chassis, top-notch ergonomics, glorious build peculiarity and an endless choice of high-end assistance and infotainment systems.

The 1.4 TFSI explosion engine is one of a many complicated appetite units of Audi. Inside a engine compartment, looking in a instruction of travel, it is positioned a few centimeters serve to a right than usual, to emanate space for a high-voltage components. Its crankcase is done from diecast aluminum, weighing small some-more than 100 kilograms (220.46 lb).

The four-cylinder engine is state of a art in any honour – a low frictional losses, a turbocharger, a intercooler and a thermal management. One special underline is a approach a empty plural is integrated into a cylinder head. After a cold start, it brings a coolant quickly adult to handling temperature. At high loads a H2O coupler lowers a heat of a empty gas.

Thanks to a high electric operation of adult to 50 kilometers (31.07 miles), many business will usually frequency knowledge a gasoline engine of a Audi A3 Sportback e-tron in action. Another outcome of a plug-in hybrid judgment is that a TFSI is mostly usually activated in kickdown situations, and is therefore subjected to high loads while still cold. For that reason, a developers have versed it with a accumulation of protecting features. These embody mutated cylinder liners and piston rings, and a sensor to magnitude oil quality.

Developing 110 kW (150 hp) and 250 Nm (184.39 lb-ft), a 1.4 TFSI is a absolute unit. It reserve rise torque opposite a whole speed operation from 1,750 by 4,000 rpm, so harmonizing excellently with a electric motor. The limit of 330 Nm (243.40 lb-ft) is accessible probably from a off, and is confirmed constantly opposite a extended speed operation adult to about 2,200 rpm. Its limit outlay is 75 kW. The complement outlay of a A3 Sportback e-tron is 150 kW (204 hp), and complement torque is 350 Nm (258.15 lb-ft). With a multiple of electric engine and explosion engine, an altogether handling operation of adult to 940 kilometers (584.09 miles) is possible. And a highway opening is unwaveringly sporty: It takes a small 4.9 seconds to scurry from 0 to 60 km/h (37.28 mph).

The electric engine is a henceforth vehement synchronous machine. It weighs 34 kilograms (74.96 lb) and is liquid-cooled around a cooling coupler in a stator. The electric engine is located between a engine’s dual-mass flywheel and a newly grown separating clutch, a K0 clutch. When a TFSI starts, it is tow-started by a electric engine around a clutch. As shortly as a former has achieved a same speed as a electric motor, a purchase is opened. This smooth, rarely accurate routine takes place within half a second.

Together with a K0 separating clutch, a electric engine is integrated into a newly designed six-speed e-S tronic, that transfers a appetite to a front wheels. Like all Audi dual-clutch transmissions, it consists of dual auxiliary transmissions that are served by a dual multi-plate clutches K1 and K2. Gears are shifted by switching a clutches. This takes usually a few hundredths of a second and happens though any conspicuous stop in propulsive power.

Depending on a turn of charge, a voltage ranges between 280 and 390 volts. The battery consists of 96 kaleidoscopic cells organised into 8 modules of twelve cells each. Including a electronic components – a battery government controller and a battery tie box – a battery complement weighs 125 kilograms (275.58 lb). Its housing is bolted to a automobile building during 5 points, and a reduce bombard is done from aluminum.

An elaborate glass cooling complement ensures that a battery is kept within a suitable heat operation during operation. Drivers of a Audi A3 Sportback e-tron will be means to start electrically in prohibited summer conditions and during sub-zero winter temperatures alike. Four cooling plates umpire a heat of a high-voltage battery’s 8 modules. The cooling complement represents a apart low-temperature circuit in a automobile and runs on a apart cooler housed in a engine compartment. If need be, it can be connected to a atmosphere conditioning complement and even divided into dual auxiliary circuits.

In a eventuality of a pile-up amply serious to trigger a belt tensioners or airbags, a whole complement is divided from a appetite supply. The flat-shaped battery is commissioned underneath a back dais chair – an area where a high-strength and ultra-high-strength steel components of a passenger dungeon form an generally clever structure. Its housing and interior structure are equally of a really stout design.

The 12-volt battery for a low-voltage consumers and a 40-liter (10.57 US gallons) fuel tank are located above a back axle. Both components hardly strike on a case of a A3 Sportback e-tron – in a customary pattern it measures 280 liters (9.89 cubic ft) and 1,120 liters (39.55 cubic ft) with a back chair backs down.

Audi reserve a A3 Sportback e-tron with a concept charging lead as standard. The patron can rotate a joining plugs so that a lead can be used both with domestic appetite sockets and with industrial appetite sockets, for full charging performance. These joining plugs are country-specific in design, so that a A3 Sportback e-tron can be recharged anywhere in a world.

For easy use during home, a charging lead can be clipped into a wall-mounted holder. Even this hilt has an Audi design, and as good as being a accessible approach to store and use a lead, it is lockable. The charging apparatus is so stable opposite burglary even when kept outdoors.

The charging lead reserve a automobile with swapping stream from a grid around a charging connection, that is in a Singleframe grille behind a fold-out 4 rings. As good as a standing LED, a section includes dual pushbuttons permitting a user to name between timer-controlled charging and evident charging. In a car, a swapping stream fed in by a horse is converted into approach stream for a battery.

From an industrial appetite socket, it takes somewhat some-more than dual hours to assign a battery fully. From a normal domestic appetite hollow in Europe, a charging routine takes about 3 hours and 45 minutes. Audi is operative intensively on a corner devise with a retailer of renewable power, since electric pushing usually creates ecological clarity if such appetite is available.

Another medium-term devise of Audi is involuntary charging though earthy contacts, referred to as Audi wireless charging. Here a charging routine involves an swapping captivating margin between a still charging pad on a belligerent and a mobile charging pad in a car, identical to a component used by an electric toothbrush.

The appetite electronics, located in a engine compartment, afterwards modify a stored approach stream into three-phase stream for a electric motor. It has 6 high-performance transistors for this task. The appetite electronics, that embody a DC/DC converter for joining adult a vehicle’s 12-volt electrical system, are compress and light in weight. They have a sum volume of 8 liters (0.28 cubic ft) and import 10 kilograms (22.05 lb). Together with a charger, it is incorporated into a same cooling circuit as a traction battery.

There are nonetheless some-more special components for electric driving. The atmosphere conditioning compressor has an electric expostulate integrated into a high-voltage network. A thermoelectric heating component and a gasoline-powered auxiliary heater turn off a interior heating system.

The hybrid government is configured to duty in peace with a electric motor. Up to middle loads a electric motor, now functioning as alternator, mostly handles retardation. The appetite that it recovers is fed into a traction battery. The circle brakes usually turn active if a motorist presses a pedal some-more forcefully.

Braking recuperation is usually one of several handling statuses of a Audi A3 Sportback e-tron. The automobile is roughly always started electrically, even during really low temperatures, in intensely prohibited conditions or when battery assign is really low. The electric motor’s high torque enables a sporty compress automobile to accelerate divided powerfully. It goes from 0 to 60 km/h (37.28 mph) in 4.9 seconds – with still though forceful propulsion.

In a electric mode a Audi A3 Sportback e-tron can transport during adult to 130 km/h (80.78 mph) – it could go faster, though that would not be efficient. When roving during a consistent 100 km/h (62.14 mph), generally usually a electric engine is active supposing there is sufficient appetite in a battery. As shortly as a motorist stairs tough on a accelerator, for instance to overtake, it prompts a TFSI to cut in around a K0 separating clutch. In a boost mode a Audi A3 Sportback e-tron accelerates with all of 350 Nm torque (258.15 lb-ft).

When a motorist releases a accelerator during high speed, a hybrid government enters a gliding mode. Now both drives are wholly deactivated and are no longer building braking torque. When stepping off a accelerator during middle and low speeds, a complement recovers appetite by coasting recuperation; braking recuperation afterwards becomes active when a stop pedal is pressed, solely if a full stop focus is needed.

The motorist has several ways of actively handling a vehicle’s response. They can name from 3 programs regulating a symbol in a pushing area and a e-S tronic selector lever. The EV evil map gives priority to electric drive, since a Audi A3 Sportback e-tron behaves really sportily in a S program. The hybrid reason mode can be comparison around a menu in a MMI. This mode preserves a electrical appetite stored in a battery for after use. In addition, a motorist can mention minute settings in a Audi expostulate name control system. Different stages of coasting recuperation are henceforth reserved to a particular Audi expostulate name modes. Within certain ranges, this enables a motorist to change how a battery is charged while on a move.

The Audi A3 Sportback e-tron displays supply accurate information about a driveline status. The powermeter in a instrument cluster shows a system’s altogether output, as good as a standing of a driveline and a battery charge. The guard for a MMI navigation and shows a appetite flows in a hybrid system. In addition, a motorist information complement displays a handling ranges and expenditure total for electricity and gasoline.

Under a Audi bond powerful Audi is now building an whole portfolio of innovative online services for a A3 Sportback e-tron. Drivers can use these to guard and conduct a far-reaching operation of functions around their iOS or android smartphone or around a web portal.

The motorist can call adult a car’s standing – such as a battery’s duration assign status, a electric operation or a stream parked location. They can module charging schemes remotely from their mobile phone or computer. They have a choice of starting and interlude charging or environment a charging timer and meridian control intrigue to simulate when they subsequent devise to expostulate a car. They can so mention in fact during what time on what days they wish to expostulate off with a battery wholly charged.

The meridian control planner, a third aspect, works similarly. The owners of an Audi A3 Sportback e-tron can for instance mention a aim heat for a interior according to a differentiated timetable. Adjusting a meridian in allege while still bending to a appetite hollow is most some-more fit than when pushing electrically, since it does not afterwards consecrate a empty on a automobile battery and so optimizes a electric range. In addition, it also adjusts a expostulate components to a suitable heat for a conditions. Finally, a web portal gives a owners a possibility to check their outing data, e.g. appetite consumption, stretch driven and speed.
