It utilizes the fuel needed efficiently without waste because of the new GHE engine series, automatic transmission, a built-in fuel coach and a more aerodynamic cab which reduces the coefficient of drag (CD) more significantly by 5 percent.

When the car is not running hot, there is a plastic louvred window behind the grille that closes off that aperture to force air around the car, rather than through it, which reduces the coefficient of drag and makes the car very slippery as it cuts through the air.
These changes are designed to reduce the coefficient of drag "Prius", which for a conventional car is 0.25, and reduce fuel consumption.
Its sleek sheet metal doesn't only give it heft and beauty but serve to lower the crossover's coefficient of drag. Inside the fifth Lexus SUV line's cabin are accoutrements that defy its "entry-level" label.
Mitsubishi also says that the slanted nose and the gradually inclined roof add to the efficiency of aerodynamics, and this reduces the coefficient of drag by 7 percent.
Altima has also improved in its coefficient of drag - to 0.26 Cd from the previous 0.29 Cd (currently similar to the GT-R).
NACA = National Advisory Committed For Aeronautics [C.sub.1] = coefficient of lift [C.sub.d] = coefficient of drag [V.sub.r] = Resultant wind velocity (m/s) [F.sub.L] = Lift Force [F.sub.D] = Drag Force [F.sub.R] = Resultant force (N) [rho] = density of air (kg/[m.sup.3]) c = chord length (m) [lambda] = tip speed ratio [V.sub.0] = velocity of wind (m/s) r = radius of blade (m) [??] = angular velocity of blade
As is expected, the Ioniq Hybrid and the Plug-in Hybrid have plenty of things in common, though it is worth noting that the fundamental vehicles for all three are the same, and all have an impressive coefficient of drag of just 0.24.
Altima has also improved in its coefficient of drag -- to 0.26 Cd from the previous 0.29 Cd* (currently similar to the GT-R).
Here, [[xi].sub.1] is the maximum deficit velocity rate inside the wake from the first vehicle; a is a coefficient (a =1.05); [C.sub.D1] is the coefficient of drag of the first vehicle; b is a coefficient (b =0.2); [x.sub.12] is the distance between the first and second vehicles [m]; [A.sub.f1] is the frontal projected area of the first vehicle [[m.sup.2]]; [U.sub.2,min] /[U.sub.1] is the ratio between the center-line velocity received by the second vehicle and the main flow received by the first vehicle; and [DRR.sub.2] (Drag Reduction Rate) is the aerodynamic drag reduction rate for the second vehicle.
You can see the styling for yourself but what you can't see is a coefficient of drag of 0.23 that makes the new E-Class one of the slipperiest saloons in the world.
