Extrusions provide multiple advantages for cross car beams
- Crash management
- Low vibration structure, particularly important when supporting massive user interface touch screens
- Lower weight than steel or magnesium
- Low tool costs; easy to produce LH / RH models
- Quick to market with short tooling lead time
- Ease of joining and assembly

Tesla Model 3 & Y
Novel design utilizing an aluminum extrusion as the central structure, with over-molded plastic and bolted-on castings in support areas.
Tesla Model S & X
Cadillac CTS V-Sport
Original: Magnesium die casting: 21.6 lbs (9.8 kg)
Redesign: Aluminum extrusion assembly: 14.4 lbs (6.5 kg) = 36% weight reduction
Aluminum Advantages over Magnesium
- 30% higher material stiffness
- Reduced weight by utilizing material where product performance value exists
- Reduced tooling, for LH / RH designs
- Quick, production-like prototypes
- Multi-material; best material in optimal location
- Tight profile tolerances over long length
