Coefficient of
Drag), low NVH, increased fuel efficiency and stability of the car at high speed.
The last order of business is the RX's new rear spoiler, which was added to help lower the crossover's
Coefficient of
drag (Cd)
while also containing the AM / FM radio and antenna and high - mount stop lamp and concealing the rear wiper.
The addition of Quattro all - wheel - drive decreases city, highway, and overall fuel economy by 1 or 2 mpg in each category, but thanks to a reduced overall weight and a lower
drag coefficient, the 2017 A4 gets better average mileage all around than the outgoing model
while also producing more power and torque.
Aerodynamic Form and Function Although the new PHEV boasts the same bold styling as the redesigned Optima, it offers distinctive design features and exterior elements that differentiate it from the gas - powered models in the Optima range,
while also achieving the segment's lowest
coefficient of
drag, tied with the Tesla Model S at 0.24 Cd.
Aerodynamic Form and Function Although the new Hybrid boasts the same bold styling as the redesigned 2016 Optima, it offers distinctive design features and exterior elements that differentiate it from the gas - powered models in the Optima range,
while also achieving a
coefficient of
drag that is among the lowest in the segment at 0.24 Cd.
A unitized structure that mixes high - strength steel and lightweight aluminum makes for an extremely rigid platform that allows the base Audi Q3 model to weigh in at just over 3,300 pounds,
while stylish but purposefully contoured bodywork coupled with wind - cheating underbody fairings yields a
coefficient of
drag of just 0.32.
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).
Although exterior dimensions and wheelbase on the Gen II Q7 have decreased marginally, this all - new iteration puts a more sophisticated visual spin on the SUV formula
while imparting an even sleeker character that brings an impressively low 0.32
coefficient of
drag.
While the body design has not changed, Hyundai says small tweaks to the exterior over the regular gas - powered Sonata give the Hybrids a
coefficient of
drag of 0.24.
The
drag coefficient stands at a Cd of 0.24 for the petrol and diesel variants
while the hybrid improves on that by going even lower with a Cd figure of 0.23.
All these features ensure a low
drag coefficient and maximum downforce —
while guaranteeing effective cooling of thermally highly stressed components.
A flatter bonnet with extra contour lines helps the new A5 achieve a class - leading aerodynamic
drag coefficient of just 0.25 Cd,
while Audi's trademark single - frame grille is lower and wider, further adding aggression.
The Bolt has a
drag coefficient of 0.32,
while the new Toyota Prius has a
drag coefficient of 0.24.
The bumper aids a
coefficient of
drag as low as 0.29 Cd
while short overhangs, and a strong shoulder - line, move to accentuate larger wheel - arch openings over bigger 19 - and 20 - inch alloy wheels (all with run - flat tyres).
Crisper creases and a more aggressive attitude are pretty much the norm here, all
while keeping that
drag coefficient as low as possible.
The company says function was a top priority, along with aesthetics — the goal was to improve handling by further increasing downforce,

Attention was given to make sure the Legend was quiet, so Honda used computer simulation using NASTRAN, a stress analysis program created by NASA, helping the car achieve a
drag coefficient of 0.32 and an interior noise level of 63 dB (measured
while the vehicle was travelling at 100 km / h (62.1 mph) using a manual transmission in 5th gear), and by using triple seals around the tops of door openings.
Specifically, according to RMI analyst Mike Simpson, «Wind tunnel testing of a Prevost H5 - 60 articulated bus demonstrates a

while maintaining similar cargo volume and exemplifying gap seals required for such streamlining.
Note that the Model S won over the Prius because
while they had the same
drag area, the Tesla had a lower
coefficient of
drag and a larger frontal area, so it did better starting from a disadvantaged position (smaller frontal areas offer less resistance to incoming air, all else being equal).
