Electric range of up to 59 kilometres in the NEDC (47 kilometres in the WLTP cycle), a sporty character, and great everyday usability: Audi is presenting the Q8 with plug-in hybrid drive. The new model closes the last gap in the Q8 range and provides an innovative combination of efficiency and power.
The SUV Coupé is available in two performance versions. The Q8 55 TFSI e quattro achieves a system output of 381HP (280 kW)1. The Q8 60 TFSI e quattroeven achieves a system output of 462HP (340 kW)2.
Audi is continuing its electrification offensive with the Q8 TFSI e quattro: The SUV Coupé is already the seventh model with plug-in hybrid drive that has been newly introduced on the market since mid-2019.
Audi is putting this drive technology completely at the service of the customer: It provides customers with a confident electric driving experience, simple charging management, and a high level of everyday usability.
The strengths of two worlds: a high-octane TFSI and a powerful electric motor
Like every plug-in hybrid, the Audi Q8 TFSI e quattro combines the power of two worlds. Its combustion engine, the 3.0 TFSI, outputs 340 HP (250 kW) and produces 450 Nm of torque 1.2. The V6 complies with the latest Euro 6 AP emissions standard.
The electric motor is a permanently excited synchronous machine (PSM) with a peak output of 100 kW. The compact electric motor is integrated in the housing of the eight-speed tiptronic.
Together with the coupling, which connects the 3.0 TFSI to the drivetrain, it forms what is known as the hybrid module.
The lithium-ion battery is installed under the luggage compartment. It contains 104 pouch cells of the latest generation that are bundled into 13 modules.
Each of these cells with flexible outer skin provides an electrical capacity of 48 Ah, and the battery system has an energy capacity of 17.8 kWh. This is 0.5 kWh more than the battery with which the Q7 TFSI e quattro** was first sold in 2019.
The Q7 is now also fitted with the battery of the latest generation, which has an increased capacity and is also more compact and around 40 kilograms lighter.
Liquid cooling, which forms its own low-temperature circuit, is an important factor for the energy capacity and performance of the battery.
If necessary, it can be connected to the coolant circuit for the air conditioning system or coupled with the second low-temperature circuit, which controls the temperature of the electric engine and power electronics.
It converts the direct current from the battery into three-phase current to power the electric motor. During recuperation, it feeds direct current back to the battery.
The electric motor and the 3.0 TFSI transmit their forces to an eight-speed tiptronic that shifts quickly and comfortably. Its electric oil pump ensures the supply even when the V6 petrol engine is deactivated.
The quattro permanent all-wheel drive system uses a centre differential with purely mechanical regulation. During normal driving operation, it distributes 40% of the torque to the front axle and 60% to the rear; if needed, it can direct the larger share of power to the axle with better traction. Up to 85% can be distributed to the front axle and up to 70% to the rear axle.
Two output levels: 462HP (340 kW) and 381HP (280 kW)
Audi offers the SUV Coupé in two output levels that differ in terms of their boost strategy, for example.
In purely electric operation, the more powerful variant, the Q8 60 TFSI e quattro, achieves a range of up to 56 kilometres in the NEDC and up to 45 kilometres in the WLTP measuring procedure, which determines to which tax category the vehicle is assigned.
The Q8 55 TFSI e quattro achieves an electric range of up to 59 kilometres in the NEDC and up to 47 kilometres in the WLTP. Up to speeds of 135 km/h their electric motors can generate the drive alone.
The Q8 60 TFSI e quattro achieves a system output of 462HP (340 kW) and a system torque of 700 Nm2. When both drives deliver their full performance, it accelerates from zero to 100 km/h in 5.4 seconds.
Top speed is electronically governed at 240 km/h. The Q8 55 TFSI e quattro delivers a system output of 381 HP (280 kW) and 600 Nm of system torque1. It sprints to 100 km/h in 5.8 seconds, and its top speed is also 240 km/h.
Intelligent and efficient: hybrid management and the predictive operating strategy
The hybrid management of the Audi Q8 TFSI e quattro** choses the optimum operating strategy for each journey automatically. The SUV Coupé starts in fully electric “EV” mode.
At low speed, a loudspeaker located in the right front wheel arch outputs the legally prescribed warning sound (AVAS, Acoustic Vehicle Alerting System).
The petrol engine is activated only when the driver depresses the right-hand pedal, known as the “active accelerator pedal,” beyond a specific level of resistance.
If they want to drive on electric power as much as possible, they can select “EV” mode in the central MMI display.
“Hybrid” mode, which is the main operating strategy of the Audi Q8 TFSI e quattro, comprises three operating modes: “Auto,” “Hold,” and “Charge.” In “Auto” mode, the hybrid system selects the optimum drive type automatically: fully electric at low speeds, the TFSI engine at higher speeds, and often a combination of the two.
Information from the immediate environment provided by the MMI is taken into account even when navigation is deactivated. The predictive operating strategy is activated when route guidance is started in the standard MMI navigation plus. Its task is to spread the battery charge over the driving route in an intelligent and efficient way.
In addition, the predictive operating strategy can charge the battery in efficient engine run phases in order to be able to run on fully electric power during ineffective phases later on, such as traffic jams or city traffic.
On the basis of the large amount of data it uses for this purpose, it develops a long-distance journey plan that is constantly updated using the navigation, environmental, and online traffic data.
In “Hold” mode, the operating strategy pursues a different goal: It keeps the battery’s existing state of charge at the current level with minor deviations.
In “Charge” mode, the aim is to charge up the battery as far as possible while driving. This makes sense when the journey ends in an urban area and the last kilometres are to be covered on purely electric power.
With the market introduction of the Q8 TFSI e quattro, its sister model, the Q7 TFSI e quattro** will also include this mode.
Who brakes wins: up to 80 kW recuperation power
The predictive efficiency assist is an important system in the Q8 with plug-in hybrid drive.
When the driver takes their foot off the accelerator pedal, it is decided whether the car switches to freewheeling with deactivated TFSI (“coasting”) or whether it decelerates via the electric motor and thereby recuperates energy.
It can regain up to 25 kW of power just by coasting. In addition, the electric motor performs all brake applications up to 0.3 g – the vast majority in everyday driving.
The hydraulic wheel brakes are activated in addition only in the case of heavier deceleration processes. The transition is virtually imperceptible; the brake pedal always provides excellent feedback and can be modulated precisely.
The Audi Q8 TFSI e quattro** achieves up to 80 kW of recuperation power while braking. When the adaptive cruise assist system (optional) is activated, the predictive efficiency assist becomes active not only during deceleration but also during acceleration.
If it is switched off, it provides the driver with prompts that indicate when it would be sensible to take their foot off the right-hand pedal: The driver feels an impulse in the active accelerator pedal and sees information displayed on the head-up display (optional) and the Audi virtual cockpit (standard).
The Q8 TFSI e quattro can be equipped with many state-of-the-art driver assist systems. One of the most important of these systems is the adaptive cruise assist, which can take over the majority of the operations for accelerating, decelerating, and keeping in the lane for the driver over long distances without relieving them of their responsibility.
A vehicle safety test performed by Europe’s most important committee, the NCAP consortium, focused on level-2 systems: The Q8 achieved the top score in this practical test.
Up to seven driving profiles: the Audi drive select system
The Audi drive select system also comes as standard in the Audi Q8 TFSI e quattro**. It offers a choice of up to seven driving profiles: comfort, efficiency, auto, dynamic, individual, offroad, and allroad (with adaptive air suspension sport, standard in the top-of-the-line version).
Audi drive select accesses the characteristics of the 3.0 TFSI, the tiptronic, the air suspension (optional with the Q8 55 TFSI e quattro**), and power steering, for example. Depending on the settings, the way in which the different suspension systems work together also changes.
For example, if the dynamic profile and the S mode of the tiptronic are activated, the electric motor provides a powerful additional boost as soon as the driver accelerates. When decelerating, freewheeling is blocked in this setting, allowing the drive to always recuperate.
Like all plug-in hybrids from Audi, the Audi Q8 55 TFSI e quattro** and the Q8 60 TFSI e quattro** impress with a high level of everyday usability.
They offer a generous amount of space for five persons, and their luggage compartments with the even loading floor that is easy to load provide a volume of 505 litres even in the base configuration, which increases to 1,625 litres when the rear bench seat is folded down.
Depending on the equipment, they can pull trailers weighing up to 3.5 metric tons (braked, 12% incline). Their quattro drive guarantees decisive advantages in terms of traction.
Extremely convenient: charging at home and on the road
The new plug-in hybrid models come with a charging cable for household and industrial power sockets as standard. With the maximum charging capacity of up to 7.4 kW, an empty battery can be fully charged in around two-and-a-half hours.
With the myAudi app, customers can use customised services from Audi connect on their smartphones. These services allow them to check the battery and range status, start charging processes, program the charge timer, and view the charge and consumption statistics. The charging stations are listed in both the app and the MMI navigation plus.
Another function of the myAudi app is the pre-entry climate control of the interior before starting the journey. Depending on the equipment, the steering wheel and seat heating as well as the seat ventilation can be activated.
In addition to the cable for the garage, the Audi Q8 TFSI e quattro** also includes a mode 3 cable for public charging terminals. Upon request, a charging service owned by Audi, the e-tron Charging Service, grants access to 150,000 AC charging points in Europe with just one card.
The new A3 Sportback 40 TFSI e* will be available in Ireland from Q1 2021.
