The front grille of a vehicle is used to direct air through the radiator. In a streamlined design the air flows around the vehicle rather than through; however, the grille of a vehicle redirects airflow from around the vehicle to through the vehicle, which then increases the drag. In order to reduce this impact a grille block is often used.
Some pathways to reduce the carbon emissions of road vehicles have been considerably studied. [5] Energy use and emissions vary largely between modes, causing environmentalists to call for a transition from air and road to rail and human-powered transport , and increase transport electrification and energy efficiency .
Vehicles as mild hybrids have a parameter for the threshold speed on which the vehicle is to switch from electric propulsion to the internal combustion engine. Introducing a higher speed as a parameter can reduce emissions and increase fuel efficiency (although it may increase strain on the battery). [2] Pluginization of hybrid or electric ...

Automakers would need to meet a new test simulating a head-to-hood impact and reduce the risks of serious-to-fatal head injuries in impacts at vehicle speeds of up to 25 mph (40 km/h), which ...
Aerodynamics is a significant element of vehicle design, including road cars and trucks where the main goal is to reduce the vehicle drag coefficient, and racing cars, where in addition to reducing drag the goal is also to increase the overall level of downforce. [21]
While Trump hasn’t backed his promise to reduce the cost of car insurance by 50 percent with any specific policy aims, his statements on the auto industry emphasize a goal of reducing costs for ...
The two main factors that impact drag are the frontal area of the vehicle and the drag coefficient. The drag coefficient is a unit-less value that denotes how much an object resists movement through a fluid such as water or air. A potential complication of altering a vehicle's aerodynamics is that it may cause the vehicle to get too much lift.
