Mixed materials 2019 Audi Q8 14.4% hot-formed steel, has a lot of aluminum

Last month, Audi announced the 2019 Q8, an all-new SUV built on a white steel and aluminum body.

The exterior of the Q8, which goes on sale in the US in the fourth quarter, is made entirely of aluminum except for a steel lid, based on an Audi chart on the company’s global media site.

“The side panel as well as the large areas of the floor, rear wheel covers and roof are made of aluminum panels, just like the frameless doors, front fenders and tailgate,” Audi wrote in a press release on Monday. “They make up 23.7 percent of the body in white.”

The chassis in white is made of 14.4 percent hot-formed steel (often high-strength steel), primarily in the driver and passenger side door rings and transmission tunnel.

Audi writes in a more detailed look at the “(hot-formed steel parts) are used for the lower section of the fender, side sills, longitudinal rear members, B-pillars and the front area of ​​the roof frame.” the body. “In some areas, Audi uses specially designed and variable wall thicknesses of between one and two millimeters well. (0.04 and 0.1 inch). These specially designed vacuums combine light weight with high strength.

Another 15 percent is cast aluminum, including suspension strut towers, sill joints and longitudinal members.

“2.4 percent is due to the aluminum profiles that make up the front sections of the longitudinal members,” Audi wrote.

The beams for the bumper and inside the doors are also aluminum, including the beams for the inner door stiffeners.

The Q8 weighs in at 4,728.9 pounds with a mild hybrid powertrain configuration, according to Audi. That’s lighter than the current-generation Audi Q7, which is 2.6 inches taller but 1.1 inches thinner.

“With its high level of rigidity, the Audi Q8 chassis provides the basis for the best workmanship, is excellent for background noise and has precise sporty handling,” wrote Audi. “Designed with the Audi Space Frame concept, it incorporates many lightweight aluminum and hot-formed steel components.”

Audi also reports that it has come up with a new way to handle torsion rings that allows OEMs to “remove the C-shaft without sacrificing comfort or safety.”

“Incorporated into both the front and rear ends, they are the basis for the precise handling of the SUV coupe, whether driving fast and agile on-road or when driving off-road,” Audi wrote. “…in a head-on collision, the forces are absorbed by the three planes of pressure on the front end. Strengthening the longitudinal members have variable wall thicknesses, which results in a controlled deformation.”

It is likely that only many of these design elements will be replaced.

Other external items to note for repairers:

• The ‘frameless’ doors in particular could receive optional acoustic glass, according to Audi. The OEM also offers a dual-windshield standard – and will offer an optional version that can be heated if the customer desires it.

• The electric opening and closing of the tailgate is standard, and the option of “foot gesture” operation is also available. An electric boot lid can also be purchased as an option. “Guided on the rails, they automatically retract when the tailgate is opened and extend again when closed,” Audi wrote.

• Both versions of the headlights use LEDs, with the optional HD Matrix version consisting of 24 individual LEDs.

“With regard to the HD matrix LED technology, the headlights and taillights not only feature the dynamic turn signal, but are also impressively tuned into the scene during locking and unlocking,” Audi wrote. “Their harmonious interaction gives the SUV a dynamic character. Q8 owners can use the myAudi app on their smartphone to activate and experience various lighting functions from the outside – a unique feature in the competitive field.”

For painters:

• An optional colored visor can link the “single-frame” front end design to the headlights.

• The Q8 has 12 color options, including “Dragon Orange and Galaxy Blue” as two new colors.

• Accessories can be painted in body color or “Scandium Gray” in optional packages, and “In the exterior S line package, a matte gray finish increases the effect of the monocoque, blade, sill bezel and window vent.”

Other highlights that may be of interest to collision handlers:

It’s no surprise for a high-end luxury car, to have suspension and chassis It can be quite fancy and will likely require some calibration and special care from crash repairers.

• For example, the optional all-wheel steering can turn the rear wheels by 5 degrees and adjust to steering either in the opposite direction or in the same direction as the front wheel depending on the vehicle’s speed. Another suspension option can be adjusted to four positions, raising the vehicle’s height by up to 3.5 inches.

• “Electronic Chassis Platform” notes the angle of the car and displays it to the driver. Hill Descent Control provides automatic braking assistance at gradients greater than 6 percent and acts as a cruise control for speeds up to 18.6 mph while the driver focuses on rough terrain.

• Convertible Hydraulic Bearings connect the front axle subframe to the engine to reduce vibration.

It is also not surprising that there are a lot of high-end luxury cars Advanced driver assistance safety technology over here.

• Audi offers four ADAS packages. The “Tour” option features “Adaptive Speed ​​Assist, which comfortably provides longitudinal and lateral control in all speed ranges” – maintaining a safe distance from other vehicles and within the vehicle lane as well as “observing the speed limit”. This package also “automatically adapts to the current speed limit, reducing speed before cornering, and during turns and roundabouts.”

• Another system that detects driver inactivity and warns him to be alert. If the driver doesn’t, the SUV “automatically stops it in its own lane” (hopefully to stop) and activates the Audi pre-sense process, which includes pre-tightening the seat belts.

• Another package in the Q8 that can identify front and rear traffic and automatically brake for frontal threats. (It appears to hit the brakes to warn the driver of a threat from behind but doesn’t really apply the automatic brakes to rear traffic.)

And get a load of Advance Aspect, which is part of this city package:

The Audi pre-sensing side reacts in the event of a side collision. It uses data from the radar sensors that Intersection Assist uses to calculate the probability of an accident involving approaching traffic from the side. The system can detect the danger of side collisions at speeds up to approx. 60 km/h (37.3 mph) and apply protective measures to help protect occupants. These include: activating the hazard lights, tightening the seat belts (reversible), improving the seating position, activating the closing operation for the roof and optional panoramic glass windows.

In the event of an imminent side impact collision at speeds of more than 25 km/h (15.5 mph), the suspension actuators in the optional Audi AI active suspension system raise the body on the compromised side by up to 80 mm (3.1 in) within half a second. So the other car collides with the car in a more shock-resistant area. The side sills and the floor structure absorb a large part of the impact forces. Cabin deformation and loads affecting occupants, particularly the thorax and abdomen, are reduced by up to 50 percent compared to a side impact with the suspension not raised. (emphasis on us).

It will be necessary for the repairman to restore functionality on this system due to the increased safety available.

“The systems in the Park plus Assist package, which will be added to the range later, support the driver while maneuvering,” Audi also wrote. “Maneuverability assist helps in the face of imminent collisions with small steering impulses and independent braking at a standstill, for example when poles are detected in a multi-storey car park. Rim warning protects against damaging the rims while parking. Numerous images from surrounding cameras allow precise maneuvering down up to a centimeter and provides a view of the traffic and a detailed view of the wheels.”

• Audi also offers Trailer Assist, which can steer the Q8 and the trailer in the back.

• All Audi ADAS systems are governed by a “tablet-sized computer installed under the driver’s seat – the central driver assistance console (zFAS). It continuously calculates a differentiated model of the surroundings. This centralized eco-model enables the assistance systems to accurately and timely interact with objects, such as Starting the braking. Navigation also becomes very precise, because the fusion of sensor data locates the driver’s car down to the selected lane.”

Repairers will encounter a slew of sensory equipment depending on the Q8’s options, including the notable self-cleaning addition on the front of the car.

“Depending on the options selected, zFAS receives data to do this from up to five radar sensors, six cameras, twelve ultrasonic sensors and a laser scanner,” Audi wrote. Installed in the left section of the monocoqueThe latter covers a field of about 80 metres (262.5 ft) In length and wide opening angle 145 degrees. In the field, it detects objects with sharp lines, even in the dark. In bad weather, the cover plate is automatically cleaned and heated.(The emphasis is on us.)
