The Volkswagen ID.3 Neo introduces a more efficient traction system, along with a restyling that includes significant cosmetic changes and the addition of a new LFP battery and an optimized electric motor. The compact electric car continues to use the MEB platform, which is specifically designed for fully electric vehicles. The top version retains its NMC battery with a capacity of 79 kWh, while entry-level models now feature LFP batteries with 50 and 58 kWh. The 58 kWh version is paired with a rear electric motor called APP350, capable of delivering 140 kW (190 hp) and 350 Nm of torque. This motor is equipped with a silicon carbide inverter, a high-end component typically found in premium 800 V electric vehicles, which helps reduce energy consumption. According to the WLTP cycle, the new Volkswagen ID.3 Neo promises a minimum consumption of 13.9 kWh per 100 km, an improvement over the previous ID.3 Pro model, which had a consumption of 15.3 kWh per 100 km. In the best conditions, the car aims for a maximum WLTP autonomy of 492 km, with a test model achieving 478 km at 14.4 kWh per 100 km. Additional data includes a peak power of 190 hp (140 kW), a net power of 95 hp (70 kW) in certain configurations, an in-service weight of 1,817 kg, and a power-to-weight ratio of 10.0 kg per horsepower. The car supports AC charging at 11 kW and DC charging at 105 kW, allowing it to charge from 10% to 80% in 26 minutes. In mixed driving conditions, the Volkswagen ID.3 Neo has an average final consumption of 14.5 kWh per 100 km, translating into a theoretical total autonomy of nearly 400 km, which is 17% less than the WLTP value. On a 500 km highway route from Lyon to Paris via the A6, the car consumed 19.5 kWh per 100 km, which would provide a theoretical autonomy of 300 km, or 210 km from 80% to 10% charge. The aesthetic changes do not significantly improve aerodynamics, with the car having a drag coefficient (Cx) slightly higher than 0.26 and a frontal area (SCx) of nearly 0.63 m². This affects consumption at high speeds, with consumption at 110 and 130 km/h being 16.4 and 20.4 kWh per 100 km, respectively. The Volkswagen ID.3 Neo includes an Eco mode that limits battery power to just over 100 kW, caps the maximum speed at 130 km/h (128 km/h on GPS), and reduces air conditioning effort. In this mode, a minimum consumption of 9.9 kWh per 100 km was achieved. Although the car loses 10 kW of power (from 204 hp to 190 hp), it retains 350 Nm of torque. The LFP battery slightly increases the total weight (1,817 kg compared to 1,740 kg), which slightly affects performance. However, the difference is minimal, with a 0-100 km/h acceleration time of 7.7 seconds and a 400 m D.A. time of 15.7 seconds. In Eco mode, the car cannot reach 130 km/h on GPS, but it still accelerates as quickly as a vehicle with a better power-to-weight ratio. The Neo is also more durable and less fatigued at the end of the charge thanks to its LFP battery, with good energy recovery even when nearly depleted. The car's braking and energy recovery performance is among the best, with a stop from 130 km/h in 60 meters. It offers four regenerative braking modes, with the B mode (One-pedal) allowing for adjustable levels of energy recovery via the touchscreen. The car's performance on fast charging stations and during long trips remains to be seen.
