It's a timeless design that has aged well, and its aerodynamic cleanliness ensures stability and
low wind noise at speed.
Such breakthroughs reflect a variety of factors, notably including more advanced aerodynamic designs that not only reduce wind resistance but
also lower wind noise.
Until the first test we can not confirm but having in mind exceptional
low wind noise in S - Class saloon, this declaration can not be a hazardous afirmation.
Observations during the trip: Pleasant ride on both smooth and patchy roads;
extremely low wind noise; fast - acting climate control; height of seats excellent for forward viewing and overall comfort; and easy - to - use voice controls.
This aerodynamic performance contributes to
impressively low wind noise, aids fuel consumption and strong high - speed stability and, of course, is vital in ensuring ideal handling balance through optimising drag and lift forces.
To
lower wind noise in the cabin, aerodynamics have also been improved to 0.33 Cd, a 0.02 lower coefficient of drag (Cd) than the former model
The sunroof has
low wind noise and doesn't leak.
On the motorway the PHV delivers a supple ride and
low wind noise, but around town the stiffer suspension results in more bumps and jolts being felt — although it's more controlled than the Kia.
With a Cx of only 0.27 for S 500 4Matic Coupe with 18 inch wheels thanks to an optimized aerodynamics (optimized underbody panelling concept, suspension lowered with 10 mm, sealing around headlamps, wheel spoilers with optimum flow ahead), Mercedes claim that S Class Coupe has
the lowest wind noise in the world.
The insulating layer of the softtop, the sealing concept of the doors and the double glazing together with the lowest Cd value of 0.29 for this segment are crucial for
the low wind noise in the interior.
The convertible model has a thick, well - insulated soft top with an electrically retractable glass window; overall its coefficient of drag is almost as good as the coupe's, which should result in
low wind noise.
Factor in
low wind noise and a smooth engine that loses its diesel clatter when warm, and the X3 is a relaxing long - distance cruiser.
The flush - mounted windshield is raked aggressively,
lowering wind noise and improving fuel efficiency simultaneously.
The virtual exterior mirrors will help reduce the e-tron's width by 150 mm and will contribute to cutting
the low wind noise.
