Active Speed Lips

Become active

With our Active Speed Lips, we have specifically further developed the idea of passive stowage lips. Our solution is equipped with a drive that automatically extends the aerodynamically effective elements at higher speeds. At slower speeds, the stacking lips remain hidden. This prevents damage and the component protects itself.

With the wind at the side

Active Speed Lips are made for high-performance vehicles: a large frontal area of the tires offers many possibilities for aerodynamic optimizations. This applies to SUVs, for example. When activated, the stacking lips guide the airflow around the tires and clear the way for efficient driving. At the same time, the air resistance of the underbody components is considerably reduced.  

For powerful mobility

The improved aerodynamics save energy and noticeably extend the range of combustion engines and electric vehicles. Different drive modes and a flexible design make the Active Speed Lips interesting for all larger vehicle types.

The most important highlights

• Maximum fuel economy and range improvement for passenger cars, including sedans, coupes, station wagons and compact/medium class SUVs without Air Dam (AAD).
• Aerodynamic effect from CD = -15 to 30 points, depending on body style and tire size
• Improvement of fuel consumption by about 0.15 to 0.20 mpg (combined cycle)
• Enables compliance with legal requirements for truck classification
• Flexible design
  • Several mechatronic drive strategies
  • Optimized for the respective vehicle model
• Impact resistant materials

Your customer benefit through our Active Speed Lips

Optimized aerodynamics

• Less pressure on resistance-inducing underbody components and tires
• Optimal form factor for every application
• Aerodynamic effect from CD = -15 to 30 points, depending on body style and tire size
• Fuel savings of approximately 0,15 to 0,20 mpg (combined cycle)

Adjustable ground clearance

• When retracted, requested ground clearance and slope angel are maintained and off-road mobility and aesthetics will be improved.
• Optimal aerodynamic adaptation of the system to higher speeds
• Rotating or linear drive concepts allow different installation methods for different aerodynamic strategies

Impact protection

• Impact resistant materials provide durability even in the most demanding conditions
