Vehicles of this platform generally carry the letter "A" in the fourth character of their VINs. Delta generally uses an independent suspension on the front and twist-beam type on the rear. The Ecotec engine is widely used, as are 4- and 6-speed automatic and 5-speed manual transmissions.

Delta II

Delta II was

' global compact car 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,

dropped the torsion beam in favour of a true IRS for the Volkswagen Golf Mk5, possibly in response to the 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 The Buick Verano () is a compact car manufactured by SAIC-GM for the GM's Buick brand since 2010. It debuted at the North American International Auto Show on January 10, 2011, during a preview of Buick's then upcoming 2012 model. It is the firs ...

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 Voltec application, the Chevrolet Volt. Production began in November 2010 with the first examples delivered to retail customers in December 2010.

D2XX/D2UX

General Motors introduced its new global platform named D2XX flexible platform in August 2012. The new platform was mainly engineered by GM's former German subsidiary

in Rüsselsheim. According to GM, the company invested US$220 million for the all-new D2XX platform. The platform was developed for compact vehicle architecture, replacing both Delta II and the midsize crossover GM Theta platform. Vehicles that use the new platform included: * 2015–2023 Chevrolet Cruze * 2015–2022 Opel Astra K * 2016–2019 Chevrolet Volt * 2018–2024 Chevrolet Equinox * 2018–2024 GMC Terrain * 2019–2023 Chevrolet Orlando * 2014–2020 Buick Envision File:2017 Chevrolet Cruze LT front 5.26.18.jpg, Chevrolet Cruze File:2018 Holden Astra (BL) LS sedan (2018-05-02) 01.jpg, Holden Astra Sedan File:Opel Astra 1.6 CDTI ecoFLEX Edition (K) – Frontansicht, 13.

GM-PATAC K

In 2015, Pan Asia Technical Automotive Center (PATAC), GM's joint development center with SAIC, revealed their own simplified variant of D2XX, known as the "GM-PATAC K" platform (rather than "K" so as to distinguish it from the former GM K platforms). The following vehicles use this variant of the platform, none of which are sold in the United States: * 2015–2023 Buick Excelle GT * 2016–2021 Chevrolet Cavalier * 2017–2023 Buick GL6 * 2019–present Chevrolet Monza * 2017–present Roewe i5/Ei5 File:2018 Buick Excelle GT front.jpg, Buick Excelle GT File:2016 Chevrolet Cavalier, front 8.13.18.jpg, Chevrolet Cavalier File:Chevrolet Monza IMG001.jpg, Chevrolet Monza File:Buick GL6 2 China 2018-03-20.jpg, Buick GL6
