Audi Declare World First with Mass Manufacturing Three Motor EV Powertrain | Electrical Car Information


Audi is systematically transferring ahead with its e-offensive: The Audi e-tron and the Audi e-tron Sportback have gotten extra agile, sharper and extra dynamic as S fashions.

The three electrical motors, two of that are positioned on the rear axle, collectively present 370 kW of increase energy and 973 Nm (717.6 lb-ft) of torque. This enables the 2 purely electrically pushed fashions to speed up to 100 km/h (62.1 mph) in 4.5 seconds. The clever drive management raises automobile security, and dynamic dealing with particularly, to a brand new degree: Along with the electrical all-wheel drive, there may be the electrical torque vectoring with lively and absolutely variable torque distribution on the rear axle.

The driving expertise of the 2 prototypes for the Audi e-tron S-models can not fail to impress with its degree of dynamism, agility and traction elevated as soon as extra. Within the S gear, each automobiles go from a standstill to 100 km/h (62.1 mph) in 4.5 seconds – nearly seamlessly and almost no noise – propulsion doesn’t finish till 210 km/h (130.5 mph), restricted electronically. Because of a strong cooling system, the drive provides the total increase energy of 370 kW and 973 Nm (717.6 lb-ft) of torque in reproducible type for eight seconds in every case. The nominal values within the D gear with out increase are 320 kW and 808 Nm (596.0 lb-ft).

By way of dealing with, the electrical S fashions can not fail to impress with their excellent agility and traction: They will speed up from a curve as dynamically as a sports activities automotive, their drive character is far more centered on the rear wheels and far more sporty in nature. If the ESC stabilization management is about to “Sport” and the Audi drive choose dynamic dealing with system is about to most efficiency with “Dynamic” mode, the drive structure facilitates a excessive degree of transverse dynamics and, on request, managed drifts as nicely. The driving habits is predictable always, and is characterised by an ultra-high degree of security and reliability.

The drive structure: three electrical motors sooner or later mass manufacturing

The brand new Audi e-tron S fashions would be the first electrical automobiles worldwide with three motors in mass manufacturing. Their drive structure is predicated on the idea with two totally different asynchronous motors (ASM); the e-tron product line was designed in modular type in step with this from the beginning.

The bigger electrical motor, which powers the rear axle within the Audi e-tron 55 fashions, has now been put in on the entrance axle in an tailored design and configured for 124 kW of energy, or 150 kW within the increase.

The smaller electrical motor now works in a modified type within the rear, along with a counterpart that’s similar in design; collectively, they provide 196 kW of energy, or 264 kW within the increase.

Innovation from the quattro pioneer: twin motor with electrical torque vectoring

The drive has been programmed for effectivity in on a regular basis life; in regular driving mode, solely the rear electrical motors work. The entrance drive is unpowered however switches itself on – with the motive force barely noticing – if the motive force wants extra energy. It additionally switches on predictively if the grip declines. It does so when friction values are low and through fast cornering.

The electrical all-wheel drive is complemented by an extra technical innovation within the type of electrical torque vectoring, which brings some great benefits of the standard sport differential into the electrical period. Every one of many rear electrical motors sends the drive forces on to the wheel by way of a transmission; there isn’t any longer a mechanical differential.

40 years following the launch of quattro know-how, Audi is thus elevating the precept of the 4 powered wheels to a totally new degree of know-how. The outcome: extra agile driving and self-steering traits, and thus the next cornering pace.

One additional benefit is the traction. If, throughout acceleration, a rear wheel comes into contact with a street floor with a low friction worth, i.e. if the street floor is roofed in black ice or has a free subsurface, the second might be distributed exactly and rapidly between the 2 motors. The total second is steadily distributed to the wheel with highly effective traction, whereas the wheel with low traction continues transferring with nearly no second.

The 2 prototypes of the e-tron S fashions drive on 20-inch alloy wheels within the 5-V-spokeS design as normal. Totally different wheels as much as 22 inches in measurement can be found on request. To attain an S-typical transverse dynamism, the tire widths within the sizes 20 inches, 21 inches and 22 inches have all been enlarged to 285 mm (11.2 in). Black brake calipers with a purple S rhombus, with six pistons on the entrance in every case, grip the big brake discs (entrance diameter: 400 mm (15.7 in)).

An extra normal function is the sporty progressive steering – its ratio turns into increasingly direct, the additional the motive force turns the steering wheel. The entrance and rear axles have been created as a five-link design. Harmonization of the elastokinematics and of the dampers has additionally been optimized for the S fashions. In an effort to even additional scale back the rolling actions throughout cornering, the stabilizers on each axles have been enlarged.

As much as 150 kW: peak energy, even throughout charging

When the motive force is on the street, the electrical S fashions might be charged with as much as 150 kW of direct present energy (HPC), reminiscent of within the European Ionity community. Which means charging from 5 to 80% solely takes round half an hour. An necessary issue for that is the frilly thermal administration system with a regular warmth pump, which cools and heats the battery, the inside and the electrical motors with 4 circuits. As well as, the Audi fashions may even have the ability to cost with as much as 11 kW of alternating present (AC).

The Audi e-tron Charging Service ensures handy entry to greater than 140,000 public charging factors in 24 European nations on request – with nothing greater than a charging card. Within the first 12 months, Audi covers the fundamental charge for the transit fee, which additionally affords entry to excessive energy charging columns.
