It's A Drag: Does Wind-Tunnel-Vision Kill Car Design?

Do you think that cars have lost their soul? Nina Tortosa, General Motors aerodynamicist for the Voltec/E-Flex programs, says that cars look more and more alike because “we all have to abide by the same laws of physics. It doesn’t matter if we don’t like them,” Nina Tortosa told WardsAuto.

Mere mortals have to contend with two certainties – death and taxes. Car designers are faced with a third one: Cd, or the drag coefficient.


When I was in advertising, countless engineers tried to explain the drag coefficient (a.k.a. “Cw-Beiwert” – we were in Germany) to me, until one found an ingenious solution: “You want a low one.”

They also told me the secret why the final car never looks like that flashy design study. The wind tunnel, or now rather the drag simulator is the big equalizer. “It’s a drag,” complained one designer to me, “those damned aerodynamics kill all my ideas.”

Joe Dehner, chief of Dodge and Ram Design at Chrysler, had the same experience: “We, as designers in the late ’80s and early ’90s, were in an organic phase, but aerodynamicists didn’t want organic lines,” he told WardsAuto. “We would take it to the wind tunnel and they would put corners on (it), and (we) would say, ‘You’re ruining my design.’”

    I don't know what the Italia's CD is, but I suspect it's good, and it's still sporting homewrecker good-looks. The obvious solution is to make everything mid-engine. Problem solved. I will post my forwarding address for royalty checks later this afternoon.

  • Kwik_Shift_Pro4X Style wise I'll give Volvo props for making boxy sporty. I would love one like this, but too much money pit potential.
  • Jbltg Nope.
  • ChristianWimmer This would be pretty cool - if it kept the cool front end of the standard/AMG G-Class models. The front ends of current Mercedes’ EVs just look lame.
  • Master Baiter The new Model 3 Performance is actually tempting, in spite of the crappy ergonomics. 0-60 in under 3 seconds, which is faster than a C8 Corvette, plus it has a back seat and two trunks. And comparable in weight to a BMW M3.
  • SCE to AUX The Commies have landed.
