Full-size class efficiency: the Audi Q8 TFSI e quattro
The Q8 with plug-in hybrid drive is an important addition to the Q8 range. The SUV coupé is available for sale in two output levels that differ in terms of their boost strategy. The Q8 55 TFSI e quattro (combined fuel consumption in l/100 km (US mpg): 2.8–2.6 (84.0–90.5); combined electric power consumption in kWh/100 km (62.1 mi): 22.9–21.9; combined CO2 emissions in g/km (g/mi): 63–59 (101.4–95.0)) delivers a system output of 280 kW (381 PS) and 600 Nm (442.5 lb-ft) of system torque, and the Q8 60 TFSI e quattro (combined fuel consumption in l/100 km (US mpg): 2.8–2.7 (84.0–87.1); combined electric power consumption in kWh/100 km (62.1 mi): 22.9–22.6; combined CO2 emissions in g/km (g/mi): 63–62 (101.4–99.8)) even delivers 340 kW (462 PS) and 700 Nm (516.3 lb-ft) of system torque that is generated by the software. The V6 combustion engine, a 3.0 TFSI, outputs 250 kW (340 PS) and 450 Nm (331.9 lb-ft) of torque in both models. A PSM with 100 kW of power and 400 Nm (295.0 lb-ft) of torque serves as the electric motor. The Q8 55 TFSI e quattro (combined fuel consumption in l/100 km (US mpg)*: 2.8–2.6 (84.0–90.5); combined electric power consumption in kWh/100 km (62.1 mi): 22.9–21.9; combined CO2 emissions in g/km (g/mi): 63–59 (101.4–95.0)) accelerates from a standstill to 100 km/h (62.1 mph) in 5.8 seconds and reaches an electronically limited top speed of 240 km/h (149.1 mph). The Q8 60 TFSI e quattro combined fuel consumption in l/100 km (US mpg): 2.8–2.7 (84.0–87.1); combined electric power consumption in kWh/100 km (62.1 mi): 22.9–22.6; combined CO2 emissions in g/km (g/mi): 63–62 (101.4–99.8)) completes the standard sprint in just 5.4 seconds, and its top speed is also 240 km/h (149.1 mph).
The lithium-ion battery contains 104 prismatic cells of the latest generation that are distributed across 13 modules. The battery system provides 17.9 kWh of energy and can be fully recharged with the maximum possible capacity of 7.4 kW in around two-and-a-half hours. The new battery is now also installed in the sister model, the Q7 TFSI e.
The Q8 55 TFSI e quattro covers up to 59 kilometers (36.7 mi) on electricity alone in the NEDC. In the WLTP measuring procedure, which determines to which tax category the vehicle is assigned, it covers up to 47 kilometers (29.2 mi). The Q8 60 TFSI e quattro achieves an electric range of up to 56 kilometers (34.8 mi) in the NEDC (45 kilometers (28.0 mi) in the WLTP). Up to speeds of 135 km/h (83.9 mph) the electric motor can generate the drive alone; while braking, it generates up to 80 kW of recuperation power.
The power of the two engines flows through a quickly and smoothly shifting eight-speed tiptronic to the quattro permanent all-wheel drive. Its core is a center differential that works entirely mechanically. 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.
Like all plug-in hybrid models from Audi, the Audi Q8 55 TFSI e quattro and the 60 TFSI e quattro offer a high level of everyday usability. They offer a generous amount of space for five persons, and their luggage compartments provide a volume of 505 liters (17.8 cu ft) even in the base configuration, which increases to 1,625 liters (57.4 cu ft) when the rear bench seat is folded down. Depending on the how they are equipped, they can pull trailers weighing up to 3.5 metric tons (7,716.2 lb) (braked, 12 percent incline). Their quattro drive guarantees decisive advantages in terms of traction, both with and without a trailer.
