Driving Dynamics

[kerbe2705]

The Chevy Vega took two years to design and was in production from 1970 through 1977. All told, 2,006,661 of them were produced. In 1971, it was Motor Trend’s “Car of the Year”.

If you watch any of the several excellent “ride-along” videos from journalists who’ve had the chance to experience the Beta prototype you’ll find that every one of them speaks of how balanced and well-planted it seems to be – even though it’s just a test “mule”. Steve Lee says of his experience that if felt like being in a sports car – tight and controlled. I think we’ve nothing to worry about.

Thank you for your reply. It’s comforting to hear of the favorable impressions from those ride-alongs.

My first exposure was when Jay Leno previewed and drove the Alpha prototype for his YouTube channel. What was bothersome was he had nothing to say of the driving dynamics. He said it was comfortable and peppy. I’m more interested in how well it rides and handles.

Oh well. Time will tell.

Seriously: Check out the videos from “Aptera Owners Club” and “Transport Evolved” on YouTube. There’s also a more light-hearted video from “Rich Rebuilds”.

I’ve read that the Polaris Slingshot is similar to a Miata and motorcycle cross. I’d imagine that the Aptera at 2200 lbs and 3.5sec or 5.5sec vs the Miata at 5.8sec and the Slingshot at 5.6sec.

I love my Miata and I can’t wait to add the Aptera to my stable.

You should seek the first opportunity for an Aptera driving experience. As the vehicle roles out of production there should be many opportunities locally with early reservation holders when they get their vehicles and or public showings.

Certainly can’t promise handling like a Porche but I think you will be pleasantly surprised and it will cost a mountain of money less to maintain.

And you will redeem yourself with the Environment😁

From their track testing with beta it looks like they were doing moose (iso double lane change) tests at about 48 mph (I counted frames and another person noticed the speedometer angle vs another shot that showed the number at the same). Apparently the porche macan seems to be failing at the base 43.5mph run due to aggressive anti-roll software. So based on this data point it would appear Aptera may handle better than a porche based on a standardized test 🤣. https://teknikensvarld.expressen.se/nyheter/bil-och-trafik/porsche-macan-behaves-strangely-in-the-moose-test-162276/

Ps: yes I realize most people assume your talking about a porche 911 but I couldn’t find its moose test results. 48 mph would put Aptera ahead of the vast majority of vehicles. The only other porche I could find results for is an 04 996 gt2 which managed 50 mph.

Pss: here is a fun video for 💩 and 🤭s. https://youtu.be/qIN8CyhYREM

Judging from the posts here from long- timers, no one wants to over-promise the dynamic excellence we all hope for with Aptera.

Among the things that should build confidence is the participation of Roush Engineering on the suspension of this vehicle which has been, at least on occasion, referred to as a roadster.

Further, the videos at the test track with the moose maneuver also work to inspire confidence along with the independent reports of the together suspension of the Beta ‘mule.’

Are these guarantees? Nope, but I think it clear the intent of those designing and making the Aptera is to meet a high-bar in this respect.

From my perspective, the difference electrification has already made over their ICE-powered stablemates – think the Volt over its sister model and the Spark EV over the regular Spark. I can state categorically the EV is a wholly different and better beast than than the underpowered, four-banger, especially with the automatic. The vastly improved dynamics come from the location of the vehicle battery and ample increase in power, both elemental aspects of the Aptera.

Yep. Light weight, wide stance, low center of gravity and Roush engineering makes this very promising. If they get it right, I won’t be that surprised, but I’ll be very happy. I have my fingers and toes crossed. Thanks for the input.

I’m hoping it has a tight turning radius. The car is capable of torque vectoring but I doubt they’ll have that out the door put hopefully soon after in an OTA, that should help. I’ve been disappointed in the turning radius in the Model 3, it’s a lot wider than I would expect in a mid sized car. The car with a surprisingly small radius was my old Chrysler 300C, it was a giant sedan but it had a remarkably tight turning radius. It was better in parking garages than my Tesla.

[kerbe2705]

Without a steerable rear wheel I doubt that Aptera will have a very tight turning radius.

[Mike-Mars]

The estimates are that it has a fairly poor turning circle / radius. It should be pointed out that’s just people looking at videos and trying to figure it out from there, not any official numbers, so the actual turning circle may be different to people’s estimates. While I’d really like to see a steerable rear wheel, I don’t think there is any chance of it happening – too heavy / extremely expensive / etc.

[paul-schultz]

Torque vectoring should be an out-the-door feature. It is a feature already available in the Elaphe software which I would think Aptera is using as its base. Elaphe doesn’t just make motors. They also make other major components such as controllers, firmware, etc. to integrate them into an OEM vendor’s vehicle.

[kerbe2705]

Aptera has said that they weren’t planning to use the Elaphe controllers…

[Andrew]

Just here to chime in my hot take on the topic of Aptera’s handling. The basic fundamentals of the Aptera design are a nontrivial benefit to enjoyable handling, not a handicap. Whatever the specifcs, the structure will be very stiff with an exceedingly low center of mass. The intrinsic suspension limitation is basically the most well-known, well-used configuration for a light, sporty feel. A 70/30 weight distro is almost inevitable given the layout. So it is basically my opinion that the team would have to make really naive mistakes for this beast to not handle in a way that is rewarding to drive.

What are my credentials for this opinion? None. I am a good cook. 👌

[kerbe2705]

@Andrew Oudin Being a good cook is an important skill – and so much better than being a bad cook! Your points are well-made, but look at the dates of the earlier comments and you’ll see that they were written during the Alpha and Beta phases of development.

Considering that the single heaviest component of the vehicle – its battery pack – is more-or-less centered between the three wheels, I’m guessing the weight distribution won’t be quite so front-biased as you posit.
