Efficient and Powerful: The New Plug-In Hybrid Models Audi Q5, A6, A7 and A8

  • Audi A8, A7 Sportback, A6 and Q5 as plug-in hybrids with a strong electric motor, high battery capacity and a new drive strategy
  • An electric range of more than 40 km according to WLTP
  • Convenient and networked charging with myAudi app

In electric-only mode not just free of local emissions but also efficient and sporty – Audi is consistently pursuing its electrification strategy with its comprehensive plug-in hybrid offensive. Audi is presenting the hybrid variants of the models A8, A7 Sportback, A6 and Q5 with an electric range of more than 40 kilometers in the WLTP cycle at the Geneva Motor Show. Thanks to different output levels, the customer has the choice between a comfort variant and a performance variant with a sporty design, depending on the model series. The new plug-in hybrid models will be available for order during the course of the year 2019.

 

Wide selection of models: The plug-in hybrid strategy of Audi
Plug-in hybrids from medium-size SUV to luxury sedan – with Q5, A6, A7 and A8 TFSI e, Audi is expanding its range of plug-in-hybrids for sustainable mobility. Depending on the model series, there is a choice of two variants with different performance and equipment: A comfort model and a variant with a sporty configuration with S line scopes, a more tightly tuned suspension and drive setup with higher boost performance of the electric motor for more dynamic handling. From now on, the new plug-in hybrid models carry the “TFSI e” signet. In the future, the “e-tron” label will remain reserved exclusively for electrically driven cars.

 

Power from two hearts: the versatile drive concept
The plug-in hybrid electric vehicles (PHEV) create enthusiasm thanks to their versatile character. In electric-only mode, for example, free of local emissions in the city, no range anxiety when driving long distances, sporty and dynamic with the with the power of two hearts from the combustion engine and electric motor: The drive concept offers a wide range.

The electric-only range of the PHEVs will account for more than 40 kilometers in the WLTP cycle for every model. The hybrid drive concept is designed so that customers can travel on around a third of their usual routes in electric-only mode during day-to-day driving.

All new plug-in-hybrids by Audi use a turbo-charged gasoline engine with direct injection that works together with an electric motor that is integrated in the transmission. A lithium-ion battery beneath the luggage compartment floor supplies the electrical energy. As a result, the electric motor can support the combustion engine during acceleration. The result: high start-off performance and powerful acceleration.

At the same time, with regard to recuperation, the drive system resembles that of the new purely electrically driven Audi e-tron*. It is designed for high efficiency and maximum recuperation performance. When breaking, the new Audi PHEV models recover up to 80 kW of energy. The electric motor handles slight decelerations, i.e. the majority in everyday traffic. For medium brake applications, the task is divided between the hydraulic wheel brakes, which perform this task alone only with a deceleration of more than 0.4 g.

 

The lithium-ion battery for the A6, A7 and A8 is made up of 104 pouch cells, which are combined in eight modules. It stores 14.1 kWh of energy at a voltage of 385 V. The lithium-ion battery in the Q5 comprises prismatic cells and has the same capacity. In each case, the cooling circuit of the battery is integrated in the low-temperature circuit, which supplies the electric motor and the power electronics. The power electronics transform the direct current of the high voltage-battery into a three-phase current for the electric motor; when recuperating, it does the opposite. The standard heat pump ensures efficient vehicle climate control and can generate up to 3 kW of heat energy from 1 kW of electrical energy with the waste heat occurring in the vehicle.

 

The powertrain: efficient combustion engine, high-performance electric motor and large lithium-ion battery capacity
The A8 with plug-in hybrid drive has a combustion engine and a permanently excited synchronous motor as an electric motor. It is integrated together with the clutch in the eight-gear tiptronic, which passes the torques to the quattro permanent all-wheel drive. The luxury liner drives as a 5.3-meter long A8 L variant with an extended wheelbase.

The Audi A7 and A6 models with plug-in hybrid drive use the same powertrain. The battery capacity is identical to that of the Audi A8 PHEV. Together with the electric motor that is integrated in the dual clutch transmission, a gasoline engine ensures that there is ample output and torque. Both models are available in two output levels with different boost performance.

The powertrain in the Audi Q5 PHEV follows the same concept as the Audi A6 and A7.

 

Drive modes and drive control: Maximum comfort and high electric range
The hybrid management of the plug-in-models is designed for maximum efficiency and customer comfort and automatically selects the optimum operation strategy. Start takes place electrically in “EV” mode as standard; the combustion engine is switched on depending on the situation.

The plug-in hybrid models have the following drive modes: “EV,” “Auto,” and “Hold.” With the operating mode button, the driver can select from these three basic settings: Priority for the electric drive, fully automatic hybrid mode or save power for a later phase of the journey. In “Auto” mode, the PHEVs use the intelligent interaction of the electric motor and the combustion engine for maximum efficiency. In “Hold” mode, the drive management controls the powertrain so that the current charge status of the battery is maintained, e.g. for driving later in electric-only mode in urban areas.

The predictive efficiency assist makes an essential contribution to increasing the electric range and ensuring maximum customer comfort. For this purpose, the intelligent drive management integrates the route profile into the control of the powertrain. The predictive operation strategy assesses both the navigation data during active route guidance and the information of the predictive efficiency assist as well as of the vehicle sensor system. Using this information, it creates rough planning for the entire route and fine planning for the upcoming kilometers. As a result, situations are recognized in which the driver should take their foot off the right pedal. The driver receives a corresponding visual indication on the display and haptic feedback via the active accelerator pedal. At the same time, anticipatory recuperation is initiated.

 

Moreover, the driver can select between the “comfort,” “efficiency,” “auto” and “dynamic” drive modes via the familiar switches in the Audi drive select dynamic handling system and thus influence the setup of the drive, suspension and steering. Depending on the setting, the thresholds from which both drives work together or the electric motor supplies the boost and thus the maximum torque change when accelerating. In “dynamic” mode, the electric motor supports the combustion engine more intensively with its electric boost performance for maximum dynamic handling.

The active accelerator pedal with variable pressure point for driving in electric-only mode supports the drive with haptic feedback for operation that is as efficient as possible. When the driver removes their foot from the accelerator, the vehicle glides freely in the automatic gear D and in the Audi drive select profiles “auto” and “efficiency” (under 160 km/h), where both the combustion engine and the electric motor are decoupled and switched off. On the other hand, in the S gear and in the “dynamic” profile, the electric motor remains active in deceleration mode and recuperates, i.e. it converts the kinetic energy into electrical energy.

The optional Audi virtual cockpit and the MMI display present all important notifications concerning electric driving: a power meter, the range and all energy flows.

 

Versatile – not only with regard to the drive: Model strategy and equipment lines
Audi offers the A6, A7, and Q5 each as comfort models and sporty and dynamic variants. The latter are being launched with particularly sporty equipment: Apart from the increased boost of the electric motor, they have an S line exterior package as standard. In addition, the A6 and A7 have a black styling package with darkened trims, brake calipers painted in red, and privacy window glazing in the rear compartment. The performance hybrids also place sporty touches in the interior. The A6 and A7 have a sport suspension as standard.

 

Convenient: Charging with the e-tron Charging Service
The compact charging system is also part of the standard equipment of the new Audi plug-in hybrids. It comprises cables for the domestic and industrial sockets and a control panel.
As an option, Audi supplies the wall-holder clip and a mode 3 cable for public charging stations. At a charge connector with an output of 7.2 kW, a full charge of the battery takes a good two hours.

While on the go, customers can charge the new plug-in hybrid models conveniently. A charging service owned by Audi, the e-tron Charging Service, grants access to a large number of public charging stations in 16 European countries on request. Preparations are being made to introduce this in other countries. Just one card is sufficient to begin charging with numerous providers. Customers have to register one time on the myAudi portal and conclude a charging contract that is subject to a fee. Invoicing always takes place at the end of the month using the stored method of payment.

At the market launch of the Audi e-tron*, Audi customers can supply their house and their garage with eco-electricity, generated free of CO2 emissions, from the “Volkswagen Naturstrom” brand. It is generated 100% from renewable sources, such as hydroelectric power plants, and its origin is certified by TÜV every year. In addition, if necessary, Audi supports customers in getting them in contact with an electrician for implementing a suitable charging solution in their own garage.

 

Charge Management from the Couch: The myAudi app
The myAudi app is also a practical tool for dealing with the vehicle. The app brings services from the Audi connect portfolio to the customer’s smartphone. Using the app, the customer can remotely check the battery and range status, start the charging process, program the charge timer and view the charge and consumption statistics.

Another function of the myAudi app is the pre-entry climate control even before setting off. It is made possible because the compressor of the air conditioning and the auxiliary heater in the vehicle work on a high-voltage basis. The customer can determine exactly how the interior should be heated or cooled while the vehicle is parked or the battery is being charged. Depending on the respective vehicle equipment, heating of the steering wheel, seats, mirror, windshield and rear window as well as the seat ventilation can be activated via the pre-entry climate control. Rapid start of the climate components is also possible when unlocking the vehicle with the key.

The Gran Turismo among the plug-in hybrids:
Audi A7 Sportback 55 TFSI e quattro

 

  • 367 hp system output, 500 Nm (368.8 lb-ft) of torque and quattro drive
  • Electric range of over 40 km (24.9 mi), electric-only driving at up to 135 km/h (83.9 mph)
  • Sportily equipped: S line, privacy glazing and sport suspension
  • Convenient charging with the Audi e-tron Charging Service and myAudi app

Audi is systematically pursuing its electrification strategy and is now offering its large four-door coupe as a powerful and efficient PHEV. Intelligent drive management with a predictive operating strategy enables high electric range, low fuel consumption and dynamic performance. The new Audi A7 Sportback 55 TFSI e quattro combines all of that with a system output of 270 kW (367 PS) (combined fuel consumption in l/100 km*: 2.1 – 1.9 (112.0 – 123.8 US mpg); combined electrical consumption in kWh/100 km*: 18.1 – 17.5; combined CO2 emissions in g/km*: 48 – 44 (77.2 – 70.8 g/mi)). A comprehensive list of standard equipment with S line exterior package and sport suspension round out the sporty look.

 

* Angaben zu den Kraftstoff-/Stromverbräuchen und CO2-Emissionen bei Spannbreiten in Abhängigkeit vom verwendeten Reifen-/Rädersatz sowie von der gewählten Ausstattung.

The drivetrain of the new plug-in hybrid Audi A7 Sportback 55 TFSI e quattro comprises a turbocharged 2-liter, four-cylinder gasoline engine with an output of 185 kW (252 PS) and 370 Nm (272.9 lb-ft) of torque and an electric motor (combined fuel consumption in l/100 km*: 2.1 – 1.9 (112.0 – 123.8 US mpg); combined electrical consumption in kWh/100 km*: 18.1 – 17.5; combined CO2 emissions in g/km*: 48 – 44 (77.2 – 70.8 g/mi)). The permanently excited synchronous motor (PSM) has a peak output of 105 kW and peak torque of 350 Nm (258.1 lb-ft). Together with the separating clutch, it is integrated into the seven-speed S tronic, which uses ultra technology to transfer the drive torque to a quattro ultra drivetrain. Total system output is 270 kW (367 PS); the maximum torque of 500 Nm (368.8 lb-ft) is already available at just 1,250 rpm. The A7 PHEV accelerates from 0 to 100 km/h (62.1 mph) in 5.7 seconds and reaches a top speed of 250 km/h (155.3 mph). As a company car, the plug-in hybrid model is subject to a lower tax rate in Germany because its electric range in the WLTP cycle is more than 40 kilometers (24.9 mi). The A7 Sportback can drive at up to 135 km/h (83.9 mph) in electric-only mode, making emissions-free highway driving easy. 

Comprising 104 pouch cells, the lithium-ion battery stores 14.1 kWh of energy at a rated voltage of 381 volts beneath the luggage compartment floor. For optimal temperature control, its cooling loop is connected to both the coolant loop for the climate control system and the low-temperature cooling loop into which the electric motor and power electronics are also integrated.

The lithium-ion battery is integrated into the rear of the vehicle below the luggage compartment floor in such as way that there is no step in the luggage compartment. Maximum usable stowage capacity with the rear seat folded down is thus 1,235 liters (43.6 cu ft).

quattro all-wheel drive in a plug-in hybrid

Typically Audi, the A7 Sportback 55 TFSI e** is also equipped with quattro all-wheel drive with ultra technology. The rear axle is activated lightning fast and predictively as needed. Recuperation of electrical energy is always via the front axle. The quattro all-wheel drive concept and the overall concept of the A7 PHEV thus stand equally for performance and efficiency. With the four-door Gran Turismo, Audi is the only premium manufacturer in the direct competitive environment to offer a plug-in hybrid with all-wheel drive.

Easy operation with three driving modes

The drive concept of the A7 Sportback 55 TFSI e quattro is designed so that customers can do the most of their daily driving electrically. Whether with zero local emissions in the city or with high range on long trips. The combination of electric motor and internal combustion engine provides for a sportily dynamic driving experience. With its three different driving modes, the plug-in hybrid is easy to operate in everyday use.

The A7 PHEV starts by default in EV mode. This means the car is driven exclusively electrically as long as the driver does not depress the accelerator past a variable, perceptible pressure point. EV mode is the base setting each time the vehicle is started. In the second driving mode, Battery Hold mode, the drive management system holds battery capacity at the current level so that a defined distance can later be covered fully electrically, for instance.

The Hybrid mode is activated either automatically together with route guidance in the navigation system or by the driver using the operating mode button. In this mode, the A7 PHEV uses the interplay between the electric motor and the internal combustion engine to complete as many driving segments as possible electrically so that overall fuel consumption at the end of the trip is as low as possible. For instance, stop-and-go traffic in cities can be driven electrically for the most part. Depending on the situation, the system chooses between freewheeling with the engine switched off and coasting recuperation. Up to 35 kW of power can be recovered with the latter. The electric motor is responsible for all light braking up to 0.1 g, i.e. the majority of braking in everyday driving. A maximum of 80 kW of electrical energy are generated via braking recuperation at a deceleration of up to 0.2 g.

Predictive operating strategy and predictive efficiency assist

For maximum efficiency the A7 uses predictive drive management – the predictive operating strategy. It uses information from the predictive efficiency assist also found in other Audi mid- and full-size class models to control the electric motor, lithium-ion battery and the internal combustion engine.

If route guidance is active in the MMI navigation system, the predictive operating strategy controls the drivetrain so that the last urban section of the route can be driven exclusively electrically and the Audi A7 PHEV arrives at the destination with the drive battery nearly empty. If the A7 Sportback TFSI e approaches a town, the drive management charges the battery so that the last urban section can be driven electrically. The driver can thus use all of the electric energy to drive with zero local emissions upon entering a town.

Drive management is controlled on the basis of a large amount of data. The predictive operating strategy uses two types of data, near field and route information, for rough and precision planning of the route. The rough planning is based on online traffic information, distance to the destination, the route profile of the chosen route, precise information about immediate surroundings from the navigation data, such as speed limits, types of roads, 
uphill and downhill slopes and the latest data from the onboard sensors. The drive controller’s rough planning is therefore based primarily on route information along the driven route, such as traffic flow, topography and road type. Precision planning, with which the A7 manages the drive controller in the current driving situation, is performed by the predictive efficiency assistant (PEA) found in other Audi mid- and large-size class models.

The predictive efficiency assistant adjusts coasting recuperation behavior to the driving situation at hand. It uses the predictable route data from the navigation database and monitors the distance to the vehicle ahead using signals from the camera and radar. Depending on the situation, the system chooses predictively between freewheeling with the engine switched off and coasting recuperation, i.e. the recovery of kinetic energy and its conversion into electrical energy. When the adaptive cruise control (ACC) is active, the PEA supports the driver by automatically braking and accelerating with the aim of enhancing efficiency and comfort.

A haptic pulse from the active accelerator pedal and an optical signal in the driver information system display as well as the optional head-up display provide additional support for the greatest possible efficiency. The active accelerator pedal has both a haptic pressure point that signals the end of electric-only driving and haptic feedback that signals the driver to take their foot off of the accelerator.

Convenient: fast charging in a short time

The charging system compact comes standard with the Audi A7 Sportback 55 TFSI e quattro**. A Mode 3 cable with Type 2 plug for use at public charging terminals is available as an option. The charging system compact comprises cables for household and industrial outlets plus a control unit. The system features an LED status display and safety functions such as temperature and residual current monitoring. Audi offers the clip wall mount, a lockable holder for the charging system, as an option.

A full charge at a three-phase CEE industrial outlet with 400 volts and 16 amperes per phase takes just approximately 2.5 hours. The vehicle charges with a maximum of 7.4 kW. Even a 230 volt household outlet can recharge an empty battery fully and conveniently overnight in approximately seven hours. Convenient recharging is also possible on the road. The proprietary Audi e-tron Charging Service provides access to more than 100,000 charging points in Europe. A single card is sufficient to start charging, regardless of the provider.

A constant eye on the state of charge: the myAudi app

The myAudi app allows customers to use the services from the Audi connect portfolio on their smartphones, which is particularly practical with electrified models. The app can be used to check the battery and range status, start the charging process, program the charge timer and view the charge and consumption statistics. Furthermore, the route planners in both the app and the MMI navigation in the car show charging stations.

Another function of the myAudi app is pre-entry climate control before setting off. The air conditioning compressor and the auxiliary heater in the car are electrically powered. The customer can determine exactly how the interior should be heated or cooled while the battery is being charged. Depending on the optional equipment chosen, the same applies to the seat and steering wheel heating, heating of the windshield, rear window and mirrors, and the seat cooling.

Clever thermal management

The air conditioning works together with a highly efficient heat pump, enabling the car to make good use of the waste heat from the electric drive train. This is particularly economical and not only enables the interior to be heated or cooled quickly, but also a high electric range even at particularly high or low outdoor temperatures.

Sporty appearance and comprehensively equipped

The Audi A7 Sportback 55 TFSI e** not only scores points against its direct competitors with sporty performance, but also with a correspondingly dynamic appearance package and comprehensive list of standard equipment. The standard S line exterior package combined with the black styling package and the privacy glazing underscore the sporty overall impression of the four-door Gran Turismo even when standing still.

HD Matrix LED headlights, sport seats, four-zone automatic air conditioning, convenience key, Audi virtual cockpit, PHEV-specific displays, 19-inch, multi-spoke wheels and red brake calipers front and rear are standard.

Orders are now being accepted for the Audi A7 Sportback 55 TFSI e quattro** at a base price in Germany of 77.850 euros. Market introduction begins in the third quarter of 2019.

 

Fuel consumption of the models named above:
Audi A7 Sportback 55 TFSI e quattro: Combined fuel consumption in l/100 km*: 2.1 – 1.9 (112.0 – 123.8 US mpg); Combined electrical consumption in kWh/100 km*: 18.1 – 17.5; Combined CO2 emissions in g/km*: 48 – 44 (77.2 – 70.8 g/mi).
