Here’s how tire and wheel choice affects electric vehicle range

Explaining the differences between 17, 18, and 19-inch tiresTires are the only part of a car that touches the road, so it shouldn't be surprising to know that they can impact electric-car range. What is perhaps unexpected is that the size really matters. Putting big wheels on an electric car could put a big dent in available range. In an Engineering Explained video, host Jason Fenske compares different...

Wind-powered transatlantic car carrier could cut carbon emissions by 90%
