Modern cars are heavier than ever before. Even small family cars now weigh hundreds of kilograms more than their equivalents from 20 or 30 years ago.
In this video, we explain why modern cars are getting heavier, looking at the main factors driving weight increases across the industry. That includes safety regulations, structural requirements, comfort features, infotainment systems, and the impact of electrification and hybrid technology.
We also explore how extra weight affects fuel efficiency, electric range, performance, braking, tyre wear, and running costs, and whether heavier cars are actually safer or better to live with.
This explainer breaks down where the weight comes from, why manufacturers are struggling to reduce it, and what it means for buyers choosing their next car.
