Opel Commodore B 2.8 GS (130 Hp)
Overall Rating
Opel Commodore:
The Opel Commodore is an executive car produced by Opel from 1967 to 1986. It is the six-cylinder variant of the Rekord with styling differences. The Commodore nameplate was used by Opel from 1967 to 1982 in Europe and to 1986 in South Africa. The Commodore nameplate was adopted by Holden in Australia, where it continued until 2020. The last generation was sold in the United Kingdom primarily as the Vauxhall Viceroy although Opel-badged models were also sold there, and the Chevrolet Commodore in South Africa from 1978 to 1982, when it was renamed the Opel Commodore....(Read more on Wikipedia)
B Overview:
Opel Commodore (B). With 206 Nm of torque, it offers ample pulling power. Weighing only 1215 kg, it’s quite light. Rear‑wheel drive offers dynamic handling and sporty feedback. Acceleration is relatively slow (0–100 km/h in 11.5 s). The top speed reaches 180 km/h. A four-door car with a separate trunk, ideal for families and daily commuting. Seating for 5 makes it ideal for daily use.
Euro NCAP testing did not exist during the production years of the Opel Commodore B (1972-1974), so no official rating is available. Safety features were rudimentary by modern standards.
2.8 GS (130 Hp) Verdict:
Performance Verdict
Provides a strong balance of power and drivability, offering a noticeable performance upgrade over the base 2.5L engine, suitable for varied driving.
Fuel Economy
Fuel efficiency is moderate, aligning with other larger displacement carburetted engines of the early 70s, not a primary selling point.
