Defined Dynamics – the design of the Audi Q4 e-tron Sportback concept
Philipp Römers, Audi Designer, exclusively reveals the design secrets behind new concept car.
The design of the e-tron GT enables sophisticated aerodynamics. Its low drag coefficient of 0.24 increases efficiency and ensures a greater range. Air inlets in the lower area of the front, controllable cooling air inlets, the rear spoiler and the smooth underbody allow the flow to lie close to the vehicle and ensure that it is cleanly detached at the rear

The new GLC is immediately recognisable as a member of the Mercedes-Benz SUV family. Standard equipment includes the AVANTGARDE exterior with Chrome package including chrome window surrounds and a new, chrome-look simulated underguard. This adds striking design features and enhances the unique proportions of the vehicle. One of the defining design highlights of the GLC is the redesigned front end, with headlamps that connect directly to the radiator grille to emphasise the vehicle’s width, and the new radiator grille as part of the standard AVANTGARDE exterior, which now has a chrome surround and a sporty louvre in matt grey with chrome trim. The AMG Line has a radiator grille with Mercedes-Benz pattern. The body design is characterised by a full, spanned surface design enriched with precisely shaped edges in the sides. These emphasise the proportions, accentuate the muscular wheel arches and create a balance between elegance and off-road performance. Wheel arch liners in the vehicle colour are available from the AMG Line upwards for the first time. These accentuate the sportiness of the AMG Line, as optional equipment in conjunction with mixed tyres. Also available as an optional extra are easy-entry running boards and, from the AMG Line upwards, a Night package.
The technological progress in the area of aerodynamics is particularly apparent. It is the first time that a suspended rear wing has been fitted on a Porsche series production car. Its swan-neck mounting is used in a similar form in the GT racing car 911 RSR and the one-make cup racing car 911 GT3 Cup. Since two aluminium brackets now hold the wing element from above, the airflow can pass undisturbed across the underside, which is aerodynamically more sensitive. This new design led to a reduction in the flow losses and not only increased the downforce, but also resulted in well-balanced negative lift conditions together with many other detailed measures. “We developed the aerodynamics of the new 911 GT3 in around 700 simulations. We spent more than 160 hours fine-tuning the car in the wind tunnel,” explains aerodynamics engineer Mathias Roll.
