Car aerodynamics and ev,s

And fule consumption and horrible looking evs, not wanting to feed the beast but i had a brain fart the other night about making a non aerodynamic ev more easy on the eye and tolerable to the masses, it could be rammed through if it was built to out conserve power than there aerodynamic counterparts, i was thinking of a big square front, not to high or proud but square and not gangster looking but decent on the eye, with a flat non curving bonnet and wind tunnels in a two piece front steel mesh grill just beside and under the headlights before the radiator to collect air and run some small turbine motors under the hood at open road speed to make a charging loop back to the batteries, and have some built in generators running on the hubs for charging, and have them exempt from the aerodynamic styles on there efficiency.

We could do a kiwi build like the trekka, and sell em overseas, if we could get a turbine built with fins like a cars interior fan motor to spin under the hood.

They would be sitting in a yard for years nobody in their right mind would buy one now .

gunna-1, Jun 27, 8:27am
Why are oldschool fj45 toyota landcruisers still popular then, because they are basic, they will sell, but the trekka idea was just an example of our ability to build something, rubbish them all you like, but new s#!t dosent suit everybody, there would be enough market for them to make a decent dime, with durable vinyl interior, the works, no modern frills at all.

Yeah - I just wonder how many ev's are going to end up being scrapped well before their BDBD (battery die by date) because one electronic system or another that is purely for driver convenience or comfort has proven to elusive or expensive to fix.

That will likely be a reality, but as for desighn, this car was once a failure

Not anymore looking back now, it would cost you a house to buy one now, and with generator technology it could mean less intensive batteries for its opperation.

So no modern frills? And therefore no safety either!
Wouldn’t stand a snowballs chance of getting on to a highway near you.
Pie in the sky nonsense.

gunna-1, Jun 27, 8:56am
No crappy cloth seats or bug eye headlights, they could have crumple zones and airbags built into them without ruining there charm.

cjohnw, Jun 27, 8:57am
It is not only evs that have the full array of convenience and safety features.
You’d be hard pressed to find a new ICE vehicle that doesn’t have just as many electronic driver aids.
Hardly relevant.

wrong, LVVTA register will get it on the road as long as it complies.

bill-robinson, Jun 27, 9:10am
who needs them? how did we live without them? wakey wakey.

cjohnw, Jun 27, 9:14am
Tough luck.
They’re here and modern car manufacturers are not going to do away with features that get them a higher safety rating for their vehicles.
Get used to it.

cjohnw, Jun 27, 9:15am
And it won’t.

The shape of the front of a car has very little effect on aerodynamics in terms of efficiency, apart from its overall frontal area, it's the back that matters, were the spill and drag happens. This is true for all sub supersonic vehicles. Pointy noses are relatively pointless up until you approach mach one.

Think fastback.

Downforce is another matter but we aren't talking formula one here.

As for turbine powered generators, completely pointless, you have to spend energy to drive your generator, no matter how its coupled only to catch a bit of it back minus the loss due to imperfect conversion. There are no perpetual motion machines. This isn't the same as regenerative braking because you are spending more energy in the first place than you would be otherwise to overcome the drag of your turbines. Regenerative braking (the motor being back driven) is only useful during braking to recapture some of the energy that would otherwise be lost as heat via friction braking.

ever been through the system, or are you guessing again?

bill-robinson, Jun 27, 10:10am
shows just how dumb the govt is, and most of the sheeple that get conned by the press releases into turning off the brain.

ronaldo8, Jun 27, 10:15am
looked at the survival stats from old vs new car accidents? we didn't live. wakey wakey

cjohnw, Jun 27, 10:35am
Whatever!
Just you being your usual negative and argumentative self.
Does not interest me in going any further.

Tell all the families of the dead F1 driver's from bygone eras that safety cells wouldn't have helped them!

bill-robinson, Jun 27, 1:10pm
this is about road cars but prove that they would have survived with a safety cell. some would have but not all. they new the risk and took the chance. as well as that the materials that a cell is made from just did not exist for a lot of the accidents.

poppy62, Jun 27, 9:13pm
Well Bill, you're the one recalling the "good' old past that claimed a lot of lives with poorly designed and constructed cars of all types. When was the last time a F1 driver died in a crash? Those old bangers are best left for collectors and Sunday drivers.

gunna-1, Jun 27, 11:37pm
Thats interesting the horrible fronts on newer cars dont serve any purpose, they certainly didnt screw the aesthetics of the 60s fastbacks up, why are they so good at screwing up car designs now.

ronaldo8, Jun 27, 11:48pm
Heh good question, the fickle fates of fashion. Id imagine some of it has to do with how a body slides up a smooth bonnet and over a windshield as opposed to be splattered on a flat grill like a bug.

Which reminds of this one time going down Franklin road in a charger whose brakes I was fixing, boy that guy at the pedestrian crossing could jump, straight over like superman.

No radiator in a EV, That leaves potential for a whole new style of car.

bill-robinson, Jun 28, 6:15am
in the modern plastic truck with outside assistance about 6 years ago i think. still nothing to do with the subject but answered to please
