Budget hatchbacks head-to-head, sized for solar
The MG4 and the Volkswagen ID.3 are two of Europe's most affordable electric hatchbacks — and here the Chinese-built car has the efficiency edge. The MG4 Extended Range draws 14.5 kWh/100km against the ID.3 Pro S's 15.4 kWh/100km — the ID.3 uses about 6% more energy per 100km. The ID.3 answers with a larger 77 kWh battery (vs the MG4's 64 kWh) and a slightly longer 549km range, but on solar it's consumption, not battery size, that sets how many panels you need.
MG4 and ID.3 are evenly matched here — check the metrics below for the trade-off that matters most to you.

Common Questions
For the same annual mileage the MG4's lower consumption (14.5 vs 15.4 kWh/100km) means it typically needs slightly fewer 400W panels than the ID.3 to cover its charging. VoltSun calculates the exact count for your address and driving habits below.
On the figures in our database the MG4 Extended Range is marginally more efficient at 14.5 kWh/100km versus the ID.3 Pro S's 15.4 kWh/100km — roughly a 6% advantage for the MG4, which is unusual for a car at this price.
Not on its own. The ID.3's 77 kWh pack is larger than the MG4's 64 kWh, but panel count depends on how much energy each car uses per 100km, not on battery capacity. The bigger battery buys range and charging flexibility, not a bigger solar system.
With slightly lower consumption, the MG4 gets a bit more driving out of the same solar array than the ID.3, which usually edges its annual solar-charging cost lower — though the difference between these two is small next to your electricity price and roof size.
