Ram might kill two birds with one stone by offering a common aftermarket accessory that also improves the truck's ...

Aerodynamic drag reduction remains a pivotal area in automotive design, balancing fuel efficiency with performance and safety. Advances in computational fluid dynamics (CFD) modelling, experimental ...

Why is your EV so efficient on paper, but loses range at high speeds or in winter? We walk through the physics of drag, ...

AAs surprising as it may seem, this is a typical road load power required relationship to vehicle speed. As rolling resistance and aerodynamic loading increase, so does the amount of power required to ...

Utility Trailer Manufacturing has introduced the Utility Aerodynamic Tail, designed to improve fuel efficiency. When paired with low rolling resistant tires and configured on a Utility dry van or ...

Philip Gelderblom has been writing professionally since the '90s. He has written mainly content on a freelance basis, including about cars, future cars, EVs, hybrids and hydrogen cars, self-driving ...

These resistant forces result from friction in mechanical components of the train and the aerodynamic drag of the moving train. As the average traveling speeds of trains have increased, aerodynamics ...

Scientists in Europe researching aerodynamic forces have opened up some interesting new avenues of study inspired by fish scales. This new understanding of the flow patterns over the surface of the ...

Adding aerodynamic devices to smooth airflow over the vehicle at highway speeds is a (relatively) cheap and easy way for fleets to improve fuel economy in long-haul tractor-trailer applications. But ...

Late Model Racecraft, out of Houston, Texas, recently had just such an opportunity to harness the air- and brain-power of GM's world-class wind tunnel facility-properly known as the Aero Lab-for a ...
