Ingolstadt / Audi’s two new models are truly electrifying. The auto giant makes a comeback in the e-car segment with Audi e-tron S and the new Audi e-tron S Sportback. The fully electric drive S models use two electric motors on the rear drive and one on the front drive. Vehicle safety and dynamic handling is raised to a new level. In the electric all-wheel drive vehicles, the rear axle is equipped with electric torque vectoring with fully variable and active torque distribution.
The new S models which have three electric motors are the world’s first mass produced electric cars. The modular construction principle determines the drive layout: The Audi e-tron 55 front axle has an upgraded version of the electric motor that is installed in the rear axle. The front and the rear electric motors in the e-tron 55 which are structurally identical but with some modifications operate in sync. 86 kWh of the 95 kWh gross energy capacity of the high-voltage battery is usable. In the WLTP cycle with one battery charge, the Audi e-tron S achieves a range upto 364 km (226.2 miles) and the Audi e-tron S Sportback does upto 370 km (229.9 miles).
The driving dynamics are delivered in a new dimension in the new Audi e-tron S and the new Audi e-tron Sportback. In S gear, they provide their full boost performance for eight seconds – 370 kW of power and 973 Nm (717.6 lb-ft) of torque (Audi e-tron S: combined electric power consumption in kWh/100 km (62.1 mi): 28.4-26.8 (WLTP); 28.2 (NEDC); combined CO2 emissions in g/km: 0; Audi e-tron S Sportback: combined electric power consumption in kWh/100 km (62.1 mi): 28.1-26.4 (WLTP); 27.6-27.5 (NEDC); combined CO2 emissions in g/km: 0). The standard sprint takes just 4.5 seconds and acceleration ends at 210 km/h (130.5 mph).
In normal driving mode, only the rear electric motors operate to improve efficiency in both the Audi e-tron S and the Audi e-tron S Sportback. If the driver wants more performance before the traction subsides, then only does the front electric motor comes into action. Electric torque vectoring enhances the all-wheel electric drive: Via a single speed transmission, the drive torques are sent directly to the respective wheels by each of the rear electric motors. Very high drive torques can be managed by need-based regulation that take just milliseconds.
