Specifications of Audi Q4 e-tron Concept 82 kWh (306 HP) Quattro
General characteristics of Audi Q4 e-tron Concept 82 kWh (306 HP) Quattro
Meet the all-new Audi Q4 e-tron: the all-electric SUV that supports what drives you. Designed to merge performance and practicality, the Q4 e-tron puts luxury electric driving firmly within reach.
Equal parts performance and art. The Q4 e-tron boasts a bold, upright fascia that not only turns heads, but also optimizes performance with improved aerodynamics.
Merging muscular surfacing with sleek design, the aggressive Q4 Sportback e-tron stands strong, but moves with exceptional grace.
The Audi Q4 e-tron is the first Audi model to feature an available augmented reality head-up display. Providing real-time vehicle information directly in your line of sight, the intuitive virtual display seamlessly blends innovative tech into your driving experience.
Rear wheel drive (RWD) models make use of a water-cooled brushless permanently excited synchronous motor positioned along the rear axle, producing up to 150 kW of power and 310 N⋅m (230 lb⋅ft) of torque and revolves at a speed of up to 16,000 rpm. The motor is coupled to a 1-speed transmission with a fixed gear ratio of 13:1 and typically operates with "substantially greater than 90 percent" efficiency.
Motor, transmission and power electronics (DC/AC converter) together form a compact drive unit that weighs around 200 lb.
For the all-wheel drive quattro model, a further asynchronous motor is positioned at the front axle, providing an additional up to 75 kW of power at a speed of 14,000 rpm when required. In most situations, the front motor is not activated in order to increase overall efficiency. Its 1-speed gear is fixed at a ratio of 10:1 while the rear motor in AWD models operates at a ratio of 11.5:1.
During braking, the rear-wheel drive models can recuperate energy up to forces of 0.15 g and up to 0.3 g in the all-wheel drive models, which equates to up to 145 kW of power. When driving, the vehicle by default is set to coast, with recuperation up to 0.15 g being optional.
The motors rotor and stator are produced at the Volkswagen Group Components plant in Salzgitter and are assembled in Kassel, where the 1-speed transmission is built as well. For the Chinese market, the electric drive components are produced in Tianjin.
The battery consists of a liquid-cooled Lithium-Ion battery pack which houses either 10 or 12 modules containing the individual battery cells in an aluminium casing. The smaller battery holds an energy content of 55 kWh, of which 52 kWh are made available, while the larger pack comes in at 82/77 kWh and weights of 770 lb and 1,100 lb, respectively.
Whereas the battery system is assembled at Volkswagen Group plants, the Nickel-Manganese-Cobalt (NMC) battery cells are obtained from suppliers such as LG Energy Solution and CATL. For the Zwickau plant, battery cells pre-assembled into modules at LGs Wroclaw plant are delivered by train to be assembled into batteries in Braunschweig.
If charged at a public DC fast charger at a rate of 125 kW under ideal conditions, Audi claims that the 82/77 kWh battery pack can charge from 5 to 80 percent in 38 minutes.
