Opel Manta B 2.0 S (100 Hp)
Overall Rating
Opel Manta:
The Opel Manta is a car which was built by German manufacturer Opel in two generations from 1970 to 1988. The Manta was a mildly sporting coupé based on the Ascona family car, competing with cars such as the Ford Capri. The Manta remained rear-wheel drive for both generations and also saw certain competition success. Its name comes from the manta ray. The first generation only has a two-door body style, whilst the second generation added a three-door hatchback alongside the two-door variant.
The Manta A was released in September 1970, two months ahead of the then new Opel Ascona on which it was based. A competitor to the Ford Capri, it was a two-door "three-box" coupé, and featured distinctive round tail lights, quite similar to those on the Opel GT and which in fact were used on the GT in 1973, its final model year. It took its name, and a few minor styling cues, from the Manta Ray concept car , which also famously influenced the 1968 Chevrolet Corvette C3. 498,553 Manta As were built from 1970 until 1975....(Read more on Wikipedia)
B Overview:
Opel Manta (B). With 153 Nm of torque, it offers ample pulling power. Weighing only 1020 kg, it’s quite light. Rear‑wheel drive offers dynamic handling and sporty feedback. Acceleration is relatively slow (0–100 km/h in 11 s). The top speed reaches 180 km/h. A two-door car with a fixed roof, known for its sporty design and dynamic performance. Seating for 4 makes it ideal for daily use.
The Opel Manta B was produced before the establishment of Euro NCAP and therefore has no official safety rating. Safety features are basic by modern standards, typical for vehicles of its era.
