Story

1958 Pontiac Bonneville

The 1958 Bonneville joined Pontiac performance with premium full-size equipment. This page keeps its body, engine, transmission, axle, chassis, trim, production, and identity evidence in one model-year record while separating every configuration path.

Engines and drivetrain

The 370-cubic-inch Strato-Streak V8 was offered in model-year-specific output and induction forms. Engine code, carburetion or fuel injection, transmission, axle ratio, cooling, exhaust, dates, and records must agree; added Tri-Power or fuel injection does not establish original delivery.

Chassis and cabin

The 122-inch-wheelbase chassis used power-assisted drum brakes and model-year suspension, steering, wheel, and tire equipment. Paint, brightwork, upholstery, instruments, and controls depended on body and selected equipment.

Identity

Begin with serial, body, trim, title, and ownership records. Reconcile the shell, drivetrain, axle, brakes, suspension, protected finish, cabin, and every dated component. Production totals describe the model family, not a survivor count or one car's authenticity.

Still Researching

  • production The reviewed public records do not provide an audited 1958 split by engine code, transmission, axle, paint, trim, options, plant, destination, or surviving cars.
  • paint colors Reviewed references establish representative factory colors but not a complete body, trim, stripe, special-order, plant, and build-date compatibility matrix.
  • interior Broad cabin equipment is documented, but the complete upholstery color, material, body, option, and production-date matrix is not publicly reconciled.
  • authenticity markers Public model references cannot prove one survivor's born-with shell, drivetrain, chassis components, paint, trim, options, or component dates.
