Dacia Bigster vs Mercedes-Benz GLB: the crossover of new models

  • Autocar describes the two-engine test of Dacia Bigster, including with a 612-litre/1977 litres luggage capacity.
  • Material from Autocar also suggests that, although the engine power is not enough, the two-engine test is more about the time of the journey.
  • Top Gear rounds up the Mercedes-Benz GLB with a similar form factor, with 250+ to 350 4Matic variants, as well as WLTP electric range of 349 to 379 miles and a 10-80% charge in 22 minutes on a 350kW post.

For more details on the Autocar and Top Gear follow-up.

In the two-engine test of the Dacia Bigster, published by Autocar on 3 August 2026, the author focuses on the price, complete with the characteristics of its 1.8-litre hybrid powertrain, as well as on the expected electric range. The material, meanwhile, notes that the Bigster version currently stands at a standard price of £30,000, while the price of the test car is £30,000 with a surcharge.

In the test, it says that the 106bhp and 129lb ft petrol engine develops, while the electric motor (running on a 1.4kWh battery) provides an additional 50bhp and 151lb ft. Based on the figures, the 0-62mph sprint takes 9.4 seconds, and the car’s acceleration is described as follows: for the petrol engine, it is expected to accelerate first, while for the electric motor — twice.

Another block from Autocar focuses on the luggage capacity. It states that the boot capacity is 612 litres, which is scaled down to 1977 litres, and also notes the practicality of the car’s luggage for storing bags. In its Journey, which is described in detail, the 3D-printed 6-inch audio system is attached to the doors.

Whereas the author wants to focus on what the function and driving of the new model are like. In particular, the material suggests that the problem with the car is the inability to accelerate; it also describes a journey on the 1674, 1975, 3186, 4927, 7245, 9825, 10,341 and 11,328 miles from Swansea to the Atwell-Wilson Motor Museum in Calne, from there to Goodwood and from there to North Yorkshire Moors. The author notes the new figures for the test stages, namely 1674, 1975, 3186, 4927, 7245, 9825, 10,341 and 11,328.

Meanwhile, Top Gear published a review of the Mercedes-Benz GLB, a model that uses a similar crossover layout with an electric motor and a mild hybrid petrol setup. The material also notes that the GLB is driven by a 10cm front end, and that the car is fitted with a standard engine.

Top Gear also provides the following comparison: RWD single motor with a name 250+ and twin motor AWD with a name 350 4Matic. In terms of layout, the 4Matic version can be equipped with a mass of up to two tonnes, while the vehicle itself is 4.73m long. The material adds that the boot has 540 litres of usable space, which is where the rear seats do not fold, and also that there is a frunk, and a storage compartment for two airline overhead locker wheelie cases.

As for practicality on the move, Top Gear notes the figures for the electric versions: for the 250+ variant, power is 268bhp and the 0-62mph time is 7.4 seconds; for the 350 4Matic, power is 349bhp and the 0-62mph time is 5.5 seconds. The material also states that the GLB uses an 85kWh battery and, depending on the trim, has an official WLTP electric range of 349 to 379 miles; it also adds that charging from 10-80 per cent takes 22 minutes on a 350kW charger.

In addition, Top Gear notes that the model comes with an 800V system: it says that the GLB can start charging at a speed of up to 400 volts (or less than 130kW), without any converter from £800. The material also states that, in testing, the 20-inch wheels achieve 3.3 mi/kWh, which translates to 280 miles, while the in-house test with a 3.6 mi/kWh figure delivers just over 300 miles.

Overall, the material points to the practical characteristics of the models in question: Autocar focuses on the two-engine test of the Dacia Bigster and its verified range on the road, while Top Gear compares the Mercedes-Benz GLB with the same crossover layout, including with the practical range.
