Insurance groups have jumped a little for the latest generation Corsa which launched at the end of 2019. The most affordable models are grouped around 10-12, while the most expensive Corsas are groups 17-19 for manual cars and up to group 22 for automatic models.
Electric-powered Corsa insurance groups are usually around 25, making them a little more expensive to cover than fuel-driven models.
Pre-2019 Corsas have low insurance groups, ranging from 3 for the most affordable models through to 8 for the most expensive, so annual cover shouldn't be too expensive.
