Demand for fuel-efficient trucks has never been higher in our current climate of sustainability and spend reduction. Since aerodynamic truck design has a critical impact on fuel efficiency, it’s... -
Tesla has stated that with the new Model 3 electric car, it wants to reduce the drag coefficient to an incredibly slippery 0.21 CD (210 counts), down from 0.24 on the Model S. But the maker also... -
The mystique of the wind tunnel as the ultimate place to perfect a car’s aerodynamics is blinding some makers to the superior abilities of digital simulation. Retiring head of design at GM... -
Emissions testing just got a whole lot more complicated than it already was for manufacturers – but it really doesn’t need to be. The latest complication originates in Europe, where... -
The disparity between published test figures and real-world fuel economy has long been a topic of discussion, and in Europe, the average gap between the two has reportedly risen to 40%. The current... -
Noise is a duality. On one hand, it can be soothing, inspirational, even emotional, like Beethoven’s 5th Symphony, or the fine-tuned thunderstorm of a Jaguar F-Type R (see Jalopnik article... -
