Design and Functionality Modifications

To accommodate the new turbo engine, Opel made significant modifications to the Speedster’s structure. The air intake system, positioned transversely between the passenger compartment and rear axle, directs air to the engine, while a custom intercooler draws air through two grilles behind the doors. The front grille was enlarged, providing a sportier look and improved airflow for cooling. Larger bonnet openings also dissipate engine heat effectively, enhancing both performance and aesthetics.
