The new Audi Q8 TFSI e quattro

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 percent of the torque to the front axle and 60 percent to the rear; if needed, it can direct the larger share of power to the axle with better traction. Up to 85 percent can be distributed to the front axle and up to 70 percent to the rear axle.

The new A3 Sportback 40 TFSI e* will be available in Ireland from Q1 2021.
