Audi has managed to improve the energy efficiency of its electric SUV and to increase the useful capacity of its battery. As a result, the autonomy of the e-tron 55 quattro increases to 436 km on the WLTP cycle, 25 km more than before.

Accusing more than 2.5 t empty, the Audi e-tron 55 quattro is not politically correct despite its electric motor. Its size does not seem adapted to a city use whereas its autonomy makes it difficult for it to evolve on the major axes, without adapted network of recharge.

Conscious of these constraints, Audi has just unveiled a technical update for its trendy pachyderm that inherits some adjustments inaugurated with its Sportback version just presented. First of all, the cooling system has been revised so that it is content with a lower power. According to Audi, this would increase the actual battery life by up to 10%, depending on the outside temperature, without compromising charging performance and battery life.

Another point that has been retouched by engineers Ingolstadt firm, the energy recovery system would rememmass more electricity. In fact, only the mapping of the system has been reviewed. The maximum level of deceleration allowed by this system using the brake pedal is still reported at 0.3g, but the intensity of energy recovery accessible by "freewheeling" via the paddles behind the steering wheel has been increased. According to Audi, these touch-ups favor pedaling by setting the energy recovery to the highest level.

The Audi e-tron 50 and 55 quattro are equipped with two asynchronous electric motors each. From now on, the engine placed on the front axle will be "Almost completely disconnected from the power supply" in normal use to limit the power consumption of the SUV. While Audi has added a propulsion variant of the sports R8 to its range, following the enthusiastic reception of the limited edition RWS (Rear Wheel Series), the German brand does not seem ready to sacrifice the quattro transmission of its SUV electric. A version with a single engine would however lighten the e-tron and would be suitable for many customers. Some versions of the future BMW iX3 could also be free from all-wheel drive.

Hope that the few adjustments made by Audi to offset the insufficient autonomy of the e-tron do not come at the expense of the life of its battery

Finally, if the total capacity of the 95 kWh battery pack of the e-tron 55 quattro does not change, its capacity changes from 84 to 86.5 kWh. With regard to the 50 quattro version, it announces a useful capacity of 64.7 kWh (71 kWh of total capacity). The buffers (Unused buffer zones to limit the wear of the batteries) thus pass to about 9% of the total capacity of the batteries. This remains an important portion when Tesla manages, for example, to offer batteries with a satisfactory lifetime, with buffers which sometimes constitute less than 5% of the total capacity. Let's hope that the few adjustments made by Audi to compensate for the insufficient autonomy of the e-tron do not come at the expense of the life of its battery.

All these changes lead to a WLTP range of 336 km for the Audi e-tron 50 quattro, and 436 km for the 55 quattro version, 25 km more than before. Even with these new edits, the e-tron remains far from the 507 km range WLTP announced by the Tesla Model X Grand Autonomy. In addition, the US SUV enjoys access to the network of Superchargers, which is a unique argument to Tesla. The Audi e-tron 55 quattro is still available from € 83,880, while the Model X is marketed from € 96,700.

Despite developments primarily software, Audi does not plan to upgrade for the e-tron already produced, while some manufacturers finally follow Tesla by making improvements to their cars after marketing. The Californian brand has just authorized higher load powers to certain versions of the Model 3 via a simple remote update (OTA).

New S line pack outside

Audi takes advantage of this update to announce a new S line pack. Like the Mercedes EQC and its AMG line finish, the e-tron S line focuses on sports with expanded air intakes, a spoiler or a specific diffuser. The air suspensions are also reviewed to offer more sporty settings.
