Chrysler has a legacy of innovation, especially when it comes to engine design. While some of their creations became icons, others faded into obscurity. These forgotten concept engines, each with its own unique story, showcase the brand’s bold attempts to push the boundaries of automotive engineering.A279 DOHC V8The A279 DOHC V8 engine was a remarkable attempt by Chrysler to enter the high-performance market in the late 1980s. This engine featured dual overhead cams and promised improved horsepower and efficiency. However, financial constraints and shifting market demands meant that the A279 never made it beyond the concept stage.A-864 Hemi Six-PackThe A-864 Hemi Six-Pack was a high-performance engine concept developed during Chrysler’s muscle car era. It featured three two-barrel carburetors and was designed to maximize power output. Despite its promising design, the A-864 was overshadowed by other Hemi engines that were more cost-effective to produce.PRV V6 TurboThe PRV V6 Turbo was a collaborative effort between Peugeot, Renault, and Volvo, with Chrysler exploring its potential use. This engine promised a unique blend of European engineering and American performance. Despite its potential, the project was eventually abandoned due to logistical and financial challenges.A-925 HEMI V10The A-925 HEMI V10 was another ambitious concept that aimed to expand the Hemi engine family. Designed for trucks and performance vehicles, this engine boasted impressive torque and power. However, the high production costs and changing market trends led to its discontinuation before it could be fully developed.L-Head Inline 6The L-Head Inline 6 was a staple in Chrysler’s lineup during the early 20th century. Known for its simplicity and reliability, this engine was eventually phased out as more advanced designs became prevalent. Despite its humble nature, the L-Head remains a significant part of Chrysler’s engineering history.Slant-4The Slant-4 engine was essentially a shortened version of the famous Slant-6. It was aimed at providing a compact yet robust powerplant for smaller vehicles. However, the Slant-4 never gained traction in the market, largely due to the success of its six-cylinder counterpart and the evolving automotive landscape.
