The Batten RE engine was designed by Rudy Sayn and Andy Schwartz of Batten Heads in Detroit, and followed the restrictions set out by Oldsmobile. The engine's cylinder head, block, and sump are all of aluminum alloy, with the sump also able to handle structural loads. The RE also has an unusual coolant distribution manifold. The RE's designers retained the valve angles and sizes, pent-roof combustion chambers, dual chain-driven camshafts, and stock piston crown shapes of the production Quad&nbsp;4.<ref name="hrm-apr1987b"/>

The RE is a [[Cylinder (engine)#Sleeve|wet sleeve]] design, with four cast iron cylinder liners attached to an upper cylinder block deck plate. With a bore of {{cvt|3.5|in|mm|0}} and a stroke of {{cvt|3.1|in|mm|0}}, the engine displaced {{cvt|1955|cc|cuin|2}}.<ref name="hrm-apr1987b"/>

The electronic fuel injection system came from Rochester Products, while Delco Electronics provided the engine's high-voltage ignition system. The RE was fitted with a single turbocharger from [[Garrett AiResearch]].<ref name="hrm-apr1987b"/>

Output estimates for the Batten RE engine range from {{cvt|750| to |900|hp|kW}}. A Batten RE engine powered the short-tail Aerotech car.<ref name="oo-aerotech"/>
