A tubular twist beam comprises a tubular body 20 including a U-shaped groove 22, tubular end sections 28, and transition sections 26 therebetween. The width w of the U-shaped groove 22 decreases continuously from each transition section 26 to a center point C of the tubular body 20 and is narrowest at the center point C to shift stress from the transition sections 26 to an area around the center point C. The tubular body 20 also includes depressions 24 along side walls 38 of each transition section 26 to direct stress to the underside of the U-shaped groove 22 and further balance the stress levels along the length of the tubular body 20. Thus, the tubular body 20 can be formed with a reduced thickness t and thus a reduced weight without sacrificing performance.
