Generation I

The first generation of modern small GM 60° V6 engines featured an iron block and heads with inline valves. This "clean sheet" design was introduced in 1980 and versions were produced through 1995. Two different blocks with minor differences were developed: * A

It was built from 1991 to 1997. From 1991 to 1993, it used tuned multiport fuel injection, made at 5200 rpm and of torque at 4000 rpm. From 1994 to 1997, it used sequential port fuel injection, making at 5200 rpm and of torque at 4000 rpm. In 1996, the heads were redesigned for better flow, as well as now making the engine an interference design and adapting the engine for federally mandated OBDII emissions. Output for the 1996-1997 LQ1 is and . It had four valves per cylinder. The engine substituted the standard camshaft for a chain driven intermediate shaft, which drives four overhead cams via a cogged belt. Adapting the 60°pushrod block for the LQ1's overhead cams significantly increased packaged engine height. Bore was increased to , and the engine's stroke was retained. Only a few interchangeable parts are use between this DOHC engine and other members of the 60° family, primarily the connecting rods and crankshaft. The heads and intake manifolds were redesigned for the 1996 model year, incorporating a larger throttle body and plenum area, slightly longer intake runners, cloverleaf combustion chambers, and larger "pill"-shaped exhaust ports. Camshafts and cam timing were also revised for the new, higher-rpm powerband. Optional from 1991 to 1993 was a Getrag 284 five-speed manual
