    Ford Notifies Mach-E Reservers of Order Completion “In The Next Few Days”

    Just got my email a few minutes ago. Oh man, between this and the Bronco reveal in a few weeks, Ford is really singing a siren song to my wallet ...

    Rear Spoiler - functional or aesthetic?

    I was seconds away from correcting you on titanium vs steel stiffness until I remembered that the moon is an oblate spheroid.

    Rear Spoiler - functional or aesthetic?

    Somebody needs to call Debra Hands, the Aerodynamic Supervisor for the Mach E, and see what she says. https://www.ford.com/mach-e/2021/media-kit/

    Concerned about lack of marketing from Ford

    Marketing is usually handled by outside firms, but they need information and access and, well, things that require groups of people and traveling. The information we HAVE seen is about how the engineers are taking the cars home to keep doing software development and validation, how Ford is...

    Rear Spoiler - functional or aesthetic?

    I've been removing an old tree stump behind my house with an axe. Chipping away a bit at a time whenever I get a chance. Is it an exercise in futility? Maybe. Is it great exercise? Absolutely. Since they wanted more interior volume, they brought the roof line up, made the rear glass more...

    For once I completely agree.

    Rear Spoiler - functional or aesthetic?

    I'm bored, so, why not. The vehicles pictured were examples of form drag, not examples of rooftop spoilers (both of them had deck lid spoilers, by the way ... one with positive angle and one with negative angle). Many, if not ALL, of the vehicles discussed so far have some kind of spoiler at...

    Rear Spoiler - functional or aesthetic?

    Great information - form drag is the term I was looking for (guess I should have read your page 1 post a little closer ?). I'm a mechanical engineer who never did particularly well in fluid dynamics but I've been reading up on racecar aerodynamics with the goal of designing a lower-drag body for...

    Rear Spoiler - functional or aesthetic?

    Spoilers with positive angle will direct air flow upwards to reduce lift and maybe net downforce depending on the setup, at the penalty of a larger wake resulting in higher drag. For example, the spoiler on Lightning McQueen. Another example would be Porsche's deployable decklid spoiler...

    Rear Spoiler - functional or aesthetic?

    From my armchair aerodynamicist's perspective, the Mach E's rear spoilers (roof and sides) are both functional AND aesthetic. Functionally, the roof spoiler probably helps reduce lift a little bit at the rear by preventing too much air flow turning downwards, in conjunction with what looks...
