Delta II

Delta II was General Motors' global compact car automobile platform, platform, developed by Opel in Germany. It was the successor to the GM Delta platform. Internally, it is simply known as a new ''Global Compact Vehicle Architecture or GCV''.

The platform features a torsion beam (marketed as ''compound crank'') rear suspension with optional Watt's linkage which improves vehicle handling; such configuration is used with the Opel Astra, Buick Verano, Cadillac ELR, Opel Cascada, and higher trim-levels of the American-market Chevrolet Cruze.

This suspension is usually described as semi-independent, meaning that the two wheels can move relative to each other, but their motion is still somewhat inter-linked, to a greater extent than in a true independent rear suspension (IRS). This can mildly compromise the handling and ride quality of the vehicle. For this reason, some manufacturers have changed to different linkage designs. As an example, Volkswagen dropped the torsion beam in favour of a true IRS for the Volkswagen Golf Mk5, possibly in response to the Ford Focus (International), Ford Focus's Control Blade rear suspension.

As noted, certain GM brands and models have continued to use the suspension setup, known variously as twist beam, torsion beam, or compound crank suspension. This is at a cost saving of €100 per car compared to multi-link rear suspension. The version used on the 2009–2015 Opel Astra and the 2011–2016 Buick Verano uses a Watt's linkage at a cost of €20 to address the drawbacks and provide a competitive and cost-effective rear suspension. The Renault Mégane and Citroen C4 also have stayed with the twist beam. The twist beam has been shown to suffer less from bushing wear than a fully independent multi-link suspension, thus resulting in a virtually maintenance-free rear suspension.

GM chose this compact vehicle architecture for its first GM Voltec powertrain, Voltec application, the Chevrolet Volt. Production began in November 2010 with the first examples delivered to retail customers in December 2010.
