Audi A6 e-tron
Audi has just unveiled its new A6 e-tron concept sedan at the Shanghai Auto show which may become an alternative fuel powertrain benchmark for the next few years. This model is the forerunner of several electrically powered models from Audi that use the new and innovative Premium Platform Electric (PPE). A production version will follow, because the model is already 90 percent ready for production.
The Audi A6 e-tron concept is 4.96 meters long, 4.96 meters wide and 1.44 meters high. This means that the model has typical A6 dimensions.
Engine And Battery Of Audi A6 e-tron
Like all future PPE models, the A6 e-tron concept features 800-volt charging technology. This means that charging with 270 kW is possible. Ten minutes of charging is then sufficient for more than 300 kilometers extra range. The 100 kWh battery pack of the A6 e-tron concept can be charged from 5-80% in less than 25 minutes. Depending on the selected configuration which includes battery pack, powertrain and system power, the Audi A6 e-tron concept has a range of up to 700 kilometers as per the Worldwide Harmonized Light-Duty Vehicles Test Procedure (WLTP). Even the future base model accelerates from 0-100 km / hr in less than 7 seconds.
The top version takes less than 4 seconds to do this. It features dual electric motors for a combined output of 350 kW and 800 Nm of torque. The study model has a multi-link suspension at the front and rear in combination with air suspension and damper control and is also featured with a Cw value of only 0.22. This strong aerodynamic value contributes to perfect aerodynamics and, in line with this, low energy consumption, which translates into a wide range. The compact virtual exterior mirrors further improve the aerodynamics.
Exterior Design Of Audi A6 e-tron
In terms of design, the A6 e-tron is a sportback. This means a long sloping rear roofline that merges directly into the tailgate. The car also gets a long hood and a signature octagonal grille that is fully closed up. Large air intakes flank the grille and sleek angular headlamps sit directly above these. At the rear, Audi has used a new generation of OLED elements to light connect the tail lamps. This is capable of some very cool looking 3D effects which may be customizable. The Matrix LED headlights can even project video games onto a wall thanks to the high resolution.
Players control the game via smartphone, or play a game Audi created specifically for the Audi A6 e-tron concept. The paintwork of the study model is called Heliosilver and can reflect a significant amount of the sun’s radiation. This reduces the heating of the interior and thus the energy consumption of the air conditioning. It rides on a set of 22-inch wheels. Three high-res LED projectors are incorporated into both sides of the body. These provide dynamic lighting effects when boarding and alighting, for example by welcoming passengers in their own language. Visual effects of these projectors can also, for example, warn cyclists about a car door being opened.
Manufacturing And Release Of Audi A6 e-tron
The production A6 e-tron will join the range in early 2023, a few months after Audi’s first PPE model, the Q6 e-tron SUV. It will sit alongside the current A6, running parallel to its model cycles. This is a similar structure to the one Mercedes is employing with its EQ range, with distinctive bespoke EV models due to sit alongside its legacy model lines. Prices will start from ₹ 36 lakhs and models based on the PPE platform will be available worldwide and will be manufactured both in Europe and in Audi’s exclusive PPE factory for China, in Changchun. Audi also plans D-segment and B-segment cars on the same platform, and perhaps even SUVs.
What Is PPE?
The basis of the PPE is a battery module placed between the shafts. As a result, the platform can be used for models with high ground clearance, such as SUVs, and models with a lower-oriented architecture, such as the A6 e-tron concept. In addition, the size of the battery pack and wheelbase of the platform are flexible.
PPE will have almost no limits to its modularity, according to Audi’s engineers, with the ability to move key hard points such as the scuttle height, dash-to-axle ratio, wheelbases, and track widths to accommodate models of all shapes and sizes. This platform also enables ‘electric quattro’ all-wheel drive with fully variable power distribution.
PPE leverages the benefits of electric drive in a familiar configuration. It consists of a large battery, low to the floor of the vehicle, placed between the axles inorder to maintain low center of gravity chassis endurance. It also illuminates the entire setup by removing the need for a large engine up front and a transmission tunnel to bring the power to the rear.
