Audi presents near-production Q8 concept SUV at Detroit

Dynamic, highly efficient and extremely comfortable: Audi is presenting the Audi Q8 concept at the 2017 North American International Auto Show (NAIAS). Serving as a prelude to a production model that will be introduced in 2018, it combines the spaciousness typical of an SUV with the elegant lines of a coupe and will tap into a new segment for Audi by offering an elegant alternative to the classic design of the full-size class. Propulsion is provided by a powerful, yet highly efficient plug-in hybrid with 330 kW of system output and 700 Nm (516.3 lb-ft) of torque. 

At 5.02 metres long, the Audi Q8 concept is an impressive presence in the full-size class. Thanks to a wheelbase of three metres, the show car offers plenty of space for passengers and luggage. Despite the sloping, coupe-like roofline, even the rear-seat passengers enjoy ample head and shoulder room. The control concept uses large touchscreens in the cockpit and is rounded out by an expanded version of the Audi virtual cockpit and a contact-analogue head-up display. The latter uses intelligent augmented reality technology that merges the real and the virtual worlds.

“The Q8 concept is an Audi in peak form. It demonstrates the strengths of our brand in both technology and design while providing a glimpse at a future full-size, production SUV,” said Dietmar Voggenreiter, Member of the Board of Management for Sales and Marketing at AUDI AG.

“With its next-generation display and control solutions, we are enabling customers to experience connectivity in a whole new way.” 

Dynamic lines and digital Matrix laser technology: the front end
The distinguishing feature at the front of the 2.04-metre-wide Audi Q8 concept is the octagonal Singleframe with honeycomb insert. It is sculpted and significantly wider than in today’s Audi production models. Six upright double bars structure the radiator grille while simultaneously emphasising its height. A mask painted in a contrasting colour frames the grille. The outer air inlets have a deep and dynamic appearance like the intakes of a turbine. A distinctive aluminium blade forms the bottom edge of the bumper.

The flat, wedge-shaped headlights of the Audi Q8 concept are integrated progressively into the exterior and connected from a design perspective to the surrounding air inlets. The individual lighting units have glass covers, but the headlights as a whole are open. This creates the impression that they are free in space. The aluminium housing for the headlights carries over the sculpture of the Singleframe. The clear geometry gives the Audi Q8 concept an unmistakable look. An x-shaped, blue laser light signature highlights the digital Matrix laser technology used for the low and high beams. Broken down into more than one million pixels, their light can illuminate the road in high resolution and with precise control. Located below the edge of the bonnet is a narrow LED light guide that emits the light for the dynamic turn signals and the daytime running lights. It wraps around the outside of the headlights, where its ribs create an innovative e-tron signature. All lighting functions are dynamic.

Athletic and powerful: the side view
The silhouette of the Audi technology study also evokes tautness. The doors do not have window frames, thus contributing to the flat roofline. The Audi Q8 concept is 1.70 metres tall. All lines on the body climb upward dynamically toward the rear – the bottom edge of the side window, the shoulders, the dynamic line and the sill lines. The surfaces of the wings, doors and side panels are athletically curved.

The lower section of the doors forms a deep fillet. Other design features are the quattro logo milled below the rear doors and also the exterior mirrors with their multifaceted edges. The doors are opened via touch sensors. As soon as the door detects hand contact, it opens easily and swings to a defined opening angle.

The extremely flat and very wide C-pillar is reminiscent of the Audi Ur-quattro from the 1980s, as are the strongly flared shoulders over the wheels. This places the concept car in a logical line with the show cars of the Audi Prologue series. The balanced proportions of the Audi Q8 concept emphasise the front and rear wheels equally – that too is typical quattro. The strongly accentuated wheel arches feature a double design. The sill region of the doors shines in brushed aluminium for an intriguing contrast to the show car’s Bombay blue paint finish.

Powerful and highly efficient: the drive system

The Audi Q8 concept uses production technologies for the drive system and suspension. Their use in the study demonstrates their importance once again. The plug-in hybrid combines impressive performance with high efficiency. The combustion engine is a 3.0 TFSI producing 333PS and a maximum of 500 Nm (368.8 lb-ft) of torque. The electric motor generates 100 kW of power and 330 Nm (243.4 lb-ft). Together with a decoupler, it is integrated into the eight-speed tiptronic. The complete system produces 330 kW and 700 Nm (516.3 lb-ft) of torque. The Audi Q8 concept accelerates from 0 to 62mph in 5.4 seconds on its way to a top speed of 155mph. According to the standard applicable for plug-in hybrids, it returns up to 122mpg in the NEDC, corresponding to 53 grams CO2 per km.

The lithium-ion battery located in the rear consists of 104 prismatic cells. With a capacity of 17.9 kWh, it enables an electric range of 37 miles, and the total range with the TFSI engine is up to 621 miles. A full charge with 7.2 kW output takes about two and a half hours.

When driving, the hybrid management system controls the operating states of the
Audi Q8 concept intelligently and flexibly. The full-size SUV can boost, coast and recuperate as appropriate for the situation. The predictive efficiency assistant, which in production models supports the driver, provides the hybrid management system with highly detailed information about the near surroundings for this purpose. Route data from the navigation system and Audi connect Car-to-X services are also considered.

The driver controls the Audi drive select system via a prismatic satellite button on the flat-bottomed steering wheel, just like the start-stop system. There is a choice of three driving modes: “EV” mode prioritises electric driving, while in “hybrid” mode the decision regarding the drive type is left largely to the hybrid management system. In “battery hold” mode, it saves the available electric energy for a later time.

High-tech from production models: drivetrain and suspension
In the Audi Q8 concept, the quattro permanent all-wheel drive system delivers the power of the hybrid drive to the road with supreme control. At the cornering limit, it works closely with the wheel-selective torque control.

This minimally brakes the inside wheels, which further enhances dynamics and stability.

The technology study also uses high-end production solutions for its wide-track suspension. The adaptive air suspension sport – an air suspension system with controlled damping – allows a wide range from cushioned cruising to firm and tight handling. In addition, it sets the ground clearance in two levels, with 90 millimetres height difference, to the ideal level in each case. The front and rear suspensions are engineered as lightweight five-link designs.

Audi mounts 305/35-series tyres on the large 11J x 23 wheels. The five intertwining Y spokes project a filigreed, three-dimensional and powerful image. Ceramic brake discs measuring 20 inches in diameter effortlessly decelerate the Audi Q8 concept.
