The Aptera Forum
What about it? All wheel drive & fast acting motor control it should do well. It will be exciting to see it in action
My question more on the ability for the Aptera to keep Passengers warm in cold weather conditions.
I currently have an Outlander PHEV and with Temps below -7'C I need to force the ICE to run, in order to get more heat into the cab. Granted it is an SUV so that there is more space to heat.
@acamara the body of the aptera is insulating. We don't know how much power the electric resistive heat will be. They want to have a heated ventilated seat option.
Maybe use wheel motor heat?
I ordered a FWD model, because my experience with FWD has been great in rain and snow, as well as on sandy pavement and loose gravel. I'm tempted to switch to the 3-wheel drive option, but my experience with 4WD has not been good, and the increased cost is about 10%.
The problem with some traditional four-wheel drive or all wheel drive systems is that they have a rear wheel bias so the rear end can get loose. Shouldn't be true for this with complete computer control.
@Daniel Watkins There is still the increased un-sprung weight and overall weight, increased components and complexity. The original appeal to me is less, not more. For me, I think the FWD option is where I want to be.
From line 65 of Aptera's FAQ Spreadsheet: "The Aptera will have a full climate control system capable down to -20 and up to 125 degrees Fahrenheit, and with our sandwich core composites body offering great insulation and a nice heater, it’s very comfortable driving in the winter."
That sounds great, because we don't want to sacrifice a lot of range, just to be comfortable. Once again, efficiency is key. Really looking forward to this!
Just saw a great interview with Nathan Armstrong on youtube: https://www.youtube.com/watch?v=IJ5sU2r-xxw&ab_channel=HoustonElectricAutoAssociation
That made me wonder if the AWD option could increase control or increase regen.
Perhaps the use of a heatpump will help instead of electric resistive.
I am afraid that heat pumps are not that effient at -20'F or lower.
Around 0' if is not
You are right. But where I live (San Diego, CA) it would work OK.
I am living in Austria and we have got a lot of Snow every year.Whats about this option?
I am little bit concerned about three wheel design in harsh winter driving conditions. When you are driving winter back roads with only two tire tracks, you have between them big hump of snow/ice. I wonder what driving experience would be? Hard to handle, does it snake around much?
This is a major concern for me as well- I am curious as to how the shrouded wheels will work in deep snow (especially as I look outside tonight here in the Midwest US tonight and we're in blizzard-like conditions)
Apparently the wheel shrouds unclip very easily, to leave at home when there's snow, or they may even fit inside the car's hatch. Personally I'd prefer these curb-proof hot-rod-look fenders year-round, since Aptera's current offerings have a minimum of 625% of my US avg range needs. They could also be quick-release AND have dual mounting heights for "street" & snow/mud:
I'm really glad to hear this, because even a few inches of snow would clog those shrouds in a flash.
I think Aptera's flexible wheel wells would be better in snow than the steel wheel wells in normal cars.
I am used to front-wheel drive vehicles. To me, they seem to handle well in the snow. My question is, how does a front-wheel drive Aptera compare in handling to other front-wheel cars in the snow? I currently drive a Mitsubishi Mirage. It seems to do better than I had anticipated and it has traction control. What would I expect from the front-wheel drive Aptera?
Aptera's Elaphe motor specs show traction correction every 1/32nd of tire revolution iirc (please correct me if I'm wrong). That would be much better than my Fiat 500e which Norwegian drivers say is great on ice. It feels to me like mine spins at least 1/2 tire spin before the computer kicks in.
