Opel decided to find out how far a C-class station wagon with 48-volt hybrid technology can travel on a single tank of fuel, achieving a result comparable to diesel cars — 1200 km.
The Opel Astra Sports Tourer Hybrid is equipped with a powertrain outputting 107 kW (145 hp) and has a fuel tank with a capacity of 52 liters. Opel test drivers set off on a journey of approximately 106 kilometers, which led from Rüsselsheim through Darmstadt to Worms and back to Opel headquarters on the left bank of the Rhine. The Astra Sports Tourer Hybrid completed this route 11 times over two days without visiting any gas stations.
The manufacturer claims that the route included a variety of road types. Test drivers traveled both on highways and on back roads and small rural roads. They reached a maximum speed of 138 km/h, passed through villages at low speeds, and had to stop in traffic jams during morning and daytime peak hours, as well as at construction sites - often in high fuel consumption mode with frequent stops. Thus, the test was conducted in everyday conditions faced by every driver. The average temperature during the test was 23 degrees Celsius.
The Opel Astra Sports Tourer Hybrid used was equipped with numerous additional options, such as a power sliding glass sunroof, which increased weight and therefore fuel consumption.
The final results of the two-day endurance test:
- The Astra Sports Tourer Hybrid covered a total of over 1200 kilometers.
- The average fuel consumption was 4.3 liters per 100 kilometers, which is 0.7 liters per 100 kilometers lower than the official WLTP figures.
- Thanks to a 15.6 kW (21 hp) electric motor and a 48-volt battery, the share of electric driving was just over 28%. In terms of kilometers, the Astra Sports Tourer Hybrid traveled around 345 kilometers during the test purely on electric power.
- The average speed across all highway sections and stops in traffic jams was 61 km/h.
However, the editors of the VOX auto mobil channel on YouTube wanted to learn more and tested the Opel Astra Sports Tourer Hybrid themselves — but not on a fixed “route,” but in a typical long drive for a vacation. Thus, two drivers set off from Munich to Sylt. In total, the editors drove 1154 kilometers across Germany without refueling. Even with two people on board (instead of one as in Opel’s internal test drive), with air conditioning on and an average speed of 78 km/h, they managed to achieve a consumption of 4.8 liters per 100 kilometers.
