The phrase
"drag coefficient" refers to the measure of drag or air resistance experienced by an object moving through a fluid (such as air or water). It indicates how easily the fluid flows around the object. A higher
drag coefficient means there is more resistance, while a lower
drag coefficient means the object encounters less resistance as it moves.
Full definition
The car has a wonderfully useful hatchback body, and that body has a shape that gives it the lowest
drag coefficient of any car around.
In short: optimum aerodynamics for the race track and an equally
good drag coefficient for everywhere else.
The incorrect
drag coefficient also affected the ball's spin, which had major implications for its lateral trajectory and speed.
This helps to ensure a considerable level of stability, a
low drag coefficient and enables a high top speed.
It features a coupe - like silhouette
with drag coefficient of 0.25 — «a new best for the SUV segment, where figures are usually considerably over 0.30», as Audi says.
Together, the new hexagonal grille, lower front air intakes and rear bumper are claimed to reduce the coupe's aerodynamic
drag coefficient from 0.33 to 0.32 Cd.
Its rakish windshield and doors that wrap into the roof give it a 33 percent improvement
in drag coefficient a measure of aerodynamic slickness over the 1987 version.
Callaway predicts a minor improvement of the overall
drag coefficient as well as a significant boost in cargo space.
The sleek shape also has outstanding aerodynamic properties for a large sedan, with an
overall drag coefficient of just 0.29 and ensuing benefits to emissions performance.
These Air Curtain, Air Breather and Aero Blade features are supposed to be functional to
improve drag coefficient, which is 0.31 Cd on the xDrive30d.
There's a huge emphasis on cooling, which hinders
drag coefficient by 3 to 4 percent compared with the 6 Series, but ensures it won't overheat.
Factor in a marginally more slippery shape (
drag coefficient drops from 0.25 to 0.24) and the Prius» claimed combined fuel economy improves from 4.7 to 4.5 L / 100 km.
Flexible body panels, front wheel air curtains, external active air flap, rear spoiler and diffuser, side sill mouldings, floor undercover and closed wheel design contribute to a class - leading
drag coefficient figure of just 0.24 Cd.
Most importantly, their sleek aerodynamic shape, closed wheel design, front wheel air curtains, rear spoiler and diffuser, side sill mouldings, floor undercover and front grille active air flap all contribute toward the car's high aerodynamic efficiency, achieving a class -
leading drag coefficient of just 0.24 Cd.
Although top speed will be electronically limited to 250km / h, the AMG coupe will also be slipperier than the sedan, given Benz is claiming a 0.26 Cd
drag coefficient for the mainstream C - Class Coupe, which helps it reduce fuel consumption by an average of no less than 20 per cent.
The Mercedes IAA actually grows in length at speeds above 50mph when extendable flaps emerge from each end to help it achieve a world
record drag coefficient of 0.19.
It's also more aerodynamic than before with the inclusion of an automatic grille shutter, bringing
drag coefficient down to just 0.24 Cd.
Its exterior panels are designed to flex to boost aerodynamics further, which, when combined with various other smart efficiency solutions, produces a class - leading
drag coefficient value of just 0.24.
Its ground breaking design puts the CLA near Chicago, IL at the top spot for the production car with the lowest
drag coefficient while providing four - door functionality.
The low stance, narrow tires and clean shape give the CLA250 a slip - through - the -
air drag coefficient of only 0.23.
The Final Editon is a bold looking thing, with a fixed carbonfibre rear wing inspired by the SLS Black Series and a carbon bonnet, Mercedes claiming that the latter increases downforce over the front axle and improves the car's
drag coefficient rating.
[13] Drag coefficient was lowered, despite growing in overall dimensions to the benefit of interior space.
Above 100 mph, however, a less
favorable drag coefficient of 0.41 (compared with the coupe's 0.33) interrupts the picture, and top speed falls from 199 mph to a still - impressive 187 mph.
The MC12 is slower in acceleration (0 — 100 km / h or 0 — 62 mph in 3.8 s), has a lower top speed of 330 km / h (205 mph) due to engine tuning and
less drag coefficient (due to sharper nose and smoother curves) than the Enzo Ferrari.
Audi increased headroom, shoulder room and legroom both in the front and rear, while also reducing noise and vibrations (the
minimum drag coefficient of 0.24 should help).
«Mobileye's ability to evolve its technology is unfortunately negatively affected by having to support hundreds of models from legacy auto companies, resulting in a very high
engineering drag coefficient,» Musk added.
Both active and passive aerodynamic aids should help the E-Pace get to a
targeted drag coefficient of 0.28, which would make it one of the world's most aerodynamic crossovers, if not the most aerodynamic.
Give a big, heavy car enough power and torque, and providing it has sufficiently tall gearing and a
decent drag coefficient, a high top speed is a given.

Hindered by a ho -
hum drag coefficient of 0.37, the final 15 mph takes a while to materialize, and there's also a fair bit of hunting going on inside the transmission, which keeps the engine far from its 6500 - rpm redline in sixth.
Despite certain flaws, the H2's on - road performance is more impressive than its appalling aerodynamics (a
bricklike drag coefficient of 0.57) and the considerable 6400 - pound curb weight suggest.
Aerodynamic technology features heavily, too, with the car's main air intakes — positioned either side of the front grille and ahead of the rear wheels — opening and closing as required, meaning they can be closed flush under most circumstances to provide a lower, slipperier and more
efficient drag coefficient.
