Our verdict

Tested here is the full hybrid Renault Symbioz. The car is positioned in the small SUV class and puts a modest 1,463 kg on the scale. Its operating strategy makes good use of the 230 V (nominal) electric system, resulting in creditable consumption values. The hybrid Symbioz surprises with a high rating score, achieved through robust emissions control, an efficient powertrain and reduced resources usage. The powertrain can be seen as an evolutionary improvement of the one used in the hybrid Dacia Bigster

  • Reduces exhaust pollutants very effectively across all tests. Scores highly for tyre abrasion and uses hybridisation to cut brake wear through regenerative braking.
  • Delivers reasonable consumption values, ranging from a low 4.2 l/100 km in warm conditions to 7.4 l/100 km in the ‑7°C cold start test. Records 6.8/100 km in the Highway Test.
  • Benefits from low fuel consumption and European production but still emits considerable CO2 from fuel combustion. Reaches life cycle emissions of 210 g CO2 eq./km, including 127 g CO2 eq./km from the exhaust.

7.5 10 Clean Air

The Symbioz's exhaust aftertreatment demonstrates high efficiency in reducing the exhaust pollutants. Emissions control is robust and ensures a very good performance across all tests, including ‑7°C cold winter testing, the high-power demand highway cycle and real-world on-road drive. The tyre abrasion score is high, reflecting little pollution, and the strong hybridisation allows significant energy recuperation and reduced reliance on the friction brake, although a pure electric vehicle performs much better in this aspect.

7.0 10 Energy Efficiency

The measured consumption results are only 4.2 l/100 km in the warm test and increase to 7.4 l/100 km in the ‑7°C Winter cold start test and to 6.8 l/100 km in the high speed and power demand Highway Test. It is worth mentioning that hybrids often lose the advantage of the hybrid system in cold weather cold start tests, as the engine needs to keep running to provide heat to the cabin and some components. The real-world mixed test was performed in rain at 18°C and recorded 5.7 l/100 km.

4.7 10 Greenhouse Gases

The low fuel consumption values help the Symbioz score better in this part of the assessment than many other combustion engine cars, but burning fossil fuel nevertheless emits significant CO2 amounts, limiting the achievable score. In the full vehicle life cycle, a total of 210 g CO2‑eq./km are estimated, 127 g CO2‑eq./km of which are direct exhaust GHG emissions. The car is produced in Europe, which benefits the results.
