A test drive of the Renault Twingo revealed its potential for low energy consumption under ideal conditions. The vehicle was tested on a carefully prepared urban circuit, with optimal weather and maximum concentration aimed at assessing its full potential. The Twingo's one-pedal driving system and regenerative braking showed promising results in traffic, though its efficiency was observed to diminish beyond 50 km/h. The test included a journey to Strasbourg via the N4, highlighting the Twingo's measured energy consumption even at stabilized speeds with cruise control. The test aimed to explore the Twingo's energy consumption limits, with an initial intuition suggesting it could reach very low levels. However, achieving these "best conditions" proved challenging, particularly in finding a suitable circuit in Strasbourg, which lacks a closed ring road. A 12.2 km loop was created using large boulevards surrounding the city center. The test began at 5:00 am with a temperature of 23°C, though weather forecasts indicated a high probability of rain or thunderstorms. During the test, the Twingo's energy consumption dropped significantly, reaching 6.6 kWh/100 km after the second lap. However, as the temperature cooled to 18°C and rain began, the energy consumption increased slightly, reaching 6.8 kWh/100 km by the 100 km mark. Factors such as traffic, waiting at red lights, and the presence of trams, buses, pedestrians, and cyclists affected the results. The Twingo's optional 18-inch wheels and Techno trim were noted to increase energy consumption by 0.3 kWh/100 km and 0.1 kWh/100 km, respectively, compared to the base model. An average of 6.8 kWh/100 km was considered excellent, providing a theoretical range of over 400 km from the Twingo's 27.5 kW battery. The test also included a comparison with the Seat Mii Electric, which achieved an average of 5.8 kWh/100 km under similar conditions. The results highlight the Twingo's efficiency in urban settings, though its performance may vary outside urban limits. The reliability of the on-board computer's figures remains a consideration.
