1930 Chevy Universal Series AD Sedan

In 1930, Chevrolet ushered in a new era of automotive excellence with the introduction of the Series AD, replacing the previous AC models in their lineup. This new series represented a significant evolution in Chevrolet’s design and engineering, offering improved performance, comfort, and style to drivers across the country.

At the heart of the Series AD was the new “stovebolt” 194 cubic inches (3.2 L) six-cylinder engine, which had been carried over from the Series AC models but underwent significant enhancements. With larger intake valves, smaller exhaust valves, and a new manifold, the power output of the engine was raised from 46 hp (34 kW) to 50 hp (37 kW). This increase in power translated to improved acceleration, responsiveness, and overall performance, making the Series AD a formidable contender in its class.

In addition to the upgraded engine, Chevrolet made several other notable improvements to the Series AD. One of the most significant changes was the inclusion of hydraulic shock absorbers in the suspension system. This upgrade provided a smoother, more comfortable ride, especially over rough or uneven terrain, enhancing the overall driving experience for passengers.

Another noteworthy change was the relocation of the fuel gauge from the fuel tank to the dash panel. This adjustment made it easier for drivers to monitor their fuel levels while driving, improving convenience and safety on the road. Additionally, Chevrolet introduced an angled, non-glare windshield, which helped to reduce glare and improve visibility for drivers in various lighting conditions.

Inside the cabin, the Series AD featured new instrument gauges with circular shapes and black faces, adding a touch of sophistication to the dashboard. These gauges not only provided essential information to the driver but also added to the overall aesthetic appeal of the interior.

Externally, the Series AD showcased a new set of wheels, with smaller 19″ wheels using wire spokes becoming standard. However, Chevrolet also offered hickory spoke wheels as an optional feature, allowing customers to customize their vehicles to suit their preferences.

Overall, the Chevrolet Series AD represented a significant leap forward for the automotive industry, offering drivers a combination of performance, comfort, and style that was unmatched in its class. With its upgraded engine, improved suspension, and thoughtful design enhancements, the Series AD set a new standard for excellence in automotive engineering, solidifying Chevrolet’s reputation as a leader in the industry.
