While I never thought I would say this... there is part of the Chevrolet Cruze that I find simply amazing:
At first glance, the torsion beam rear suspension looks pretty unimpressive, but chassis engineers have incorporated some interesting features. Because the Delta II platform is designed to be sold in markets around the world with various bodystyles, flexibility was needed to tune the suspension for various applications. A typical torsion beam setup has a lateral V-shaped beam joining the trailing arms. The Cruze (and other Delta models including Astra and Volt) has a steel tube with a pinched central section, and GM uses a patented helical welding process at the outer ends to connect the beam and control arms.
The beam itself provides the roll control function of an anti-roll bar. By varying the thickness of the steel in the tube, the engineers can adjust the car's rear roll stiffness. The tube can also be rotated for different vehicles to change the orientation of the pinched section. By doing this, the roll steer effect of the rear axle (the angle of the wheels as they move up and down that affects the handling of the car) can be changed. A Watts link has also been incorporated to help manage the lateral position of the wheels, the first such application with a torsion beam axle in a production car. A lateral link from the rear end of each trailing arm is attached to the central crank mounted to a sub-frame. As lateral loads build, the linkage puts a counter-acting force on the opposite wheel to keep the whole setup centered under the car.

Imagine the fact that in essence you could "TUNE" your beam axle for certain forms of competition...
