Speaking to Sun Motors, Tom Banks, a car insurance expert at Go.Compare, explained that the model of the car is just one of many factors insurers consider.

He said: “When an insurer offers you a quote for your car insurance, they take into account a whole range of factors – your age, the area you live in, and where your car is parked can all affect the price, as well as the type of car you drive.
“Generally speaking, more powerful, sporty cars with larger engines are more expensive to insure, while cars with smaller engines are typically more affordable to insure and run.
“While it’s unlikely to be cost-effective to change your car solely to lower your insurance premium, if you’re in the market for a new car anyway, it’s definitely worth researching how much different models cost to insure.
“And if you’re not planning to buy a new car but your premiums have increased, there are certain steps you can take to try to reduce the cost of insuring your vehicle.”
Go.Compare car insurance top tips
- Pay annually: Paying monthly for your car insurance could cost you more - insurers view this as a loan and add interest, making it more expensive over the year. So if you can afford to, pay it all in one go.
- Consider the cover type: While you might think that opting for less cover is cheaper, this isn’t always the case. Our data shows that third-party-only policies cost an average of £588, £138 more than comprehensive policies (£450).
- Job descriptions matter: If there are multiple titles you can use to describe your profession accurately, try them all out, as your car insurance premium could vary depending on which you use - but remember to always be truthful and accurate with your insurer.
- Time when you buy: Our data shows that you can make some serious savings if you shop in advance of your renewal date. In fact, it could cost you 30% more if you leave it to the day your policy is due for renewal.
