GM experimented with aluminum engines starting in the early 1950s.

Unfortunately, the great expense of the aluminum engine led to its cancellation after the 1963 model year.

Problems associated with its innovative aluminum engine led to the model's discontinuation after seven model years in 1977.

Somewhere on that mostly aluminum engine block was the man's name engraved in Japanese symbols.

The industry had fooled around for a couple of decades with aluminum engines.

Each of the auto companies at one time or another had an aluminum engine, GM most recently in the early 1960s.

And each in turn rejected their aluminum engines primarily because they cost too much to build.

So aluminum engines for smaller cars were generally rejected.

The heat distortion problems of aluminum engines have never been fully solved.

The cars are powered by a 1.9-liter, four-cylinder aluminum engine.
