The Opel Omega DTM (Deutsche Tourenwagen Meisterschaft) 1991 was a quintessential representation of Opel's commitment to dominating the competitive world of touring car racing during the early 1990s.

Inside the cockpit, the focus was on optimizing driver comfort and control. The interior was stripped down to reduce weight, featuring a roll cage for safety and a minimalist dashboard with essential instruments and controls. A specially designed racing seat with harnesses provided the driver with secure seating during intense maneuvers, while ergonomic considerations ensured that controls were within easy reach, allowing drivers to focus entirely on the race.

The Opel Omega DTM 1991 was characterized by its sleek and aerodynamically optimized exterior design, tailored specifically for high-speed racing. The body featured a wide and aggressive stance, with flared wheel arches accommodating large racing wheels and tires. The front end was distinguished by a prominent splitter and air intakes designed to optimize airflow and cooling, while the rear boasted a large wing for enhanced downforce and stability at high speeds. The overall design emphasized both form and function, ensuring maximum performance on the racetrack.
