The way of the electrification is to be undertaken by Audi continues with the sports models, the e-tron S-and e-tron S Sportback. Two Suv electric high performance, characterized by technology and innovation, capable of taking from 0 to 100 km/h in 4.5 seconds and reach maximum speed of 210 km/h.
To push the cars are three electric motors that deliver a maximum output in the boost mode, “S”, of 503 Hp with a torque of 973 Nm, while in the mode “D” of the transmission values amounted, respectively, to 435 Hp and 808 Nm.
The e-tron and e-tron S Sportback are the first electric cars in the world made in large series to have three asynchronous electric motors: the larger, which drives the rear axle on the e-tron 55 the Four, is mounted on the front axle thanks to the media changed, and offers a power output of 168 Hp (204 Hp in boost mode).
The smallest engine, adapted than that of the e-tron 55 the Four, he is now working at the rear, flanked by a second unit “twin” and will deliver a total of 266 Hp (359 Hp in boost mode).
in the name of efficiency, under normal conditions, are activated the rear thrusters while the front motor intervenes when it is necessary a greater boost in sporty driving, or, proactively, if the adhesion should decrease because of the road surface slippery.
“The all-wheel drive Quattro power is accompanied by a technical innovation – the experts – the torque vectoring electric, which distributes torque between the rear wheels bringing the benefits guaranteed by the “classic” differential, a sporty Audi in the era of zero-emission mobility.
Each of the motors at the rear axle transmits the thrust through a system of gears to the wheel closest. In so doing, the differential mechanical is no longer necessary. 40 years after the introduction of the Quattro, Audi is evolving their 4WD bringing it to a technical level that is unprecedented.
The function torque vectoring and electrical, and the consequent distribution of the thrust between the rear wheels, is activated in a few milliseconds, while managing torque values are considerably high.
Accelerating with the decision on the exit of the curve, is transmitted to the rear wheel outer up to 220 Nm of torque more than what is directed to the inner wheel.
An operation that takes place with a time four times faster than a mechanical system and the transmissions of torque significantly higher.
The new e-tron S-and e-tron S Sportback can be recharged with alternating current (AC), standard up to 11 kW, or in direct current (DC) with outputs of up to 150 kW in less than half an hour allows you to get 80% of autonomy.
The look of the two models, the e-tron S is characterized by the grid single frame octagonal and the lower edge of the Led headlamps with four horizontal segments that the function of the daytime running lights add to the signature bright.
The bumper by the specific design, integrating the insert of the extractor to the entire width, while the wheel arches of the S models are wider than 23 mm compared to those of the e-tron 55 Quattro and e-tron Sportback 55 Four and the finish alluminium look extends to the front splitter, inserts of the doors, the puller and the single frame.
In the cockpit, dominated by the dark tones and the board, divided into horizontal levels, creates a unique arch wrap-around, called a “wrap-around”, which extends up to the door trim, while the display mirror rear-view outside the virtual (optional) connect perfectly to the eyelid of the virtual cockpit oriented to the driver.
standard equipment includes sports seats, electrically adjustable and leather/Alcantara, the selector of the transmission, the slats door sill and the steering wheel are then embellished by the logo S.
Always a standard are alloy wheels 20” 5-spoke V-design specific, and the front brake calipers, six-piston calipers acting on discs internally vented, from 400 mm diameter at the front end.
also noteworthy is the presence of steering the progressive with sport settings, able to adapt the gear ratio in function of the steering angle, and adjust the servo assistance in relation to speed. (m.r.)
