Opel GT I 1.1 SR (67 Hp)
Overall Rating
Opel GT:
The Opel GT is a front-engine, rear-drive two-seat sports car manufactured and marketed by Opel in two generations separated by a 34-year hiatus.
The first generation Opel GT debuted as a styling exercise in 1965 at the Paris and Frankfurt motor shows. The production vehicle used mechanical components from the contemporary Opel Kadett B and two-door hard top bodywork by French contractor Brissonneau & Lotz. The styling of the GT was often cited as similar to the 1968 Chevrolet Corvette which went on sale in September 1967....(Read more on Wikipedia)
I Overview:
Opel GT (I). With 84 Nm of torque, it offers ample pulling power. Weighing only 853 kg, it’s quite light. Rear‑wheel drive offers dynamic handling and sporty feedback. The top speed reaches 155 km/h. A two-door car with a fixed roof, known for its sporty design and dynamic performance. Seating for 2 makes it ideal for daily use.
The Opel GT I predates modern crash testing standards like Euro NCAP, which began in 1997. As a vehicle from the late 1960s, it lacks contemporary safety features and structural rigidity, offering minimal occupant protection by today's standards.
1.1 SR (67 Hp) Verdict:
Performance Verdict
The 1.1 SR engine provides modest performance, suitable for relaxed cruising and city driving rather than spirited acceleration. Its 67 Hp is sufficient for the lightweight chassis but won't excite enthusiasts.
Fuel Economy
Given its small displacement and carburettor setup, fuel economy would be reasonable for the era, though not exceptional by modern standards. Expect moderate consumption.
Pros and Cons:
Pros:
- • Stunning, timeless design often compared to the Corvette.
- • Engaging driving dynamics, especially with the 1.9L engine.
- • Relatively lightweight and agile.
- • Strong classic car appeal and community support.
- • Simple, robust mechanicals for easier maintenance.
Cons:
- • Limited interior space and practicality (2-seater, small trunk).
- • Lack of modern safety features.
- • Rust can be a significant issue on unrestored examples.
- • Base 1.1 SR engine can feel underpowered.
- • Fixed headlights can be a quirky maintenance point.
