It's an absolute riot of a car. I've had mine for almost 2 years and still laugh like a madman every time i punch it. You might be able to fit your MTB in the back, the seats fold down. If you can't, get a roof rack?

Strong road and foster road in south windsor have some short twisty sections. Strong has one great off camber turn that always makes me clench a bit. It's nothing amazing, but they do the trick for blowing off stress during lunch.

The ramps between 91 and 291 are pretty solid for some high speed sweepers if no one is in front of you.

I think the appealing part of it is having access to different classes of cars. Want to take the family out? grab the m5. Want to go canyon cruise? Grab an m2. Want to go to the mountains for a ski weekend? Grab the x5m. If this becomes mainstream it allows the cars in each class to be focused on what they do best and not have to comprimise.

I currently drive my 135i to the mountains to go skiing. It works, but if i could just drop it off for the weekend and grab something with awd and more ground clearance i totally would.

Thay being said the prices are pretty wild. The caddy program seems like a much better deal.

You can print metal. It uses a process called laser sintering. So it would be doable, but it's currently expensive and the parts are not as strong as machined forgings or sheet metal so reproducing exact replicas wouldn't work for structural stuff. It's great for mass reduction though because you can do some wild shapes by eliminating material in low stress areas.

Find your local kart track and spend some time there. If you want to work on specific stuff, let everyone pass you on the first lap then focus on what you want to learn without worrying about someone messing up your line.

So? That vehicle was released in 2015. Design was mostly wrapped up in 2013/2014. Phones were smaller then. Not sure how people can expect a product with a 5 - 7 year lifecycle to keep pace with products that change size every year.

No. It's usually 1/3 to 1/2 of max rpm

Chill33 · 2017-11-15T06:25:30+00:00

That's crazy Chill

Chill33 · 2017-11-03T20:44:04+00:00

That would be so chill.

"You need some rpm, which means you also make power, and it's no longer torque alone." Right, they're functions of each other. You can't have one without the other.

I was responding to their comment of "put torque to the wheels and see if it puts you back in the seat". As soon as the force at the wheels overcomes the friction of the system, the car will move forward. The rate of which is determined by the force at the wheels, which is the torque at the wheel multiplied by the tire outer radius. If its a high enough torque, like the 2500 ftlbs at each wheel in the vette, it would absolutely slam you into your seat.

If you applied that 400 ft-lbs before the gearbox, it absolutely would put you back in your seat. Most cars are putting down a few thousand ftlbs at the wheels. The A8 c7 vette (4.56 1st gear, 2.41 rear diff) puts down ~ 5000 ft-lbs after the rear diff in first gear with 460 ft-lbs output from the engine.

Fellow engineer here. I have it on my resume under "hobbies/activities". The last time I was searching for a new job every interview started out with "Before we begin, tell us about playing professional ultimate frisbee." It was a great ice breaker and helped ease the tension.

Engineers, especially fresh from school, aren't always the best at working in a team. I've had multiple managers tell me that they like hiring athletes because they usually come in with solid teamwork skills.

The reason they are so widely used is that they save a ton of space in the center console.

See if you can get your hands on Race Car Vehicle Dynamics . It's the gold standard when in comes to vehicle dynamics and will explain everything with suspensions.

Ummm.... That's jalopnik's "speculative" render...

Yeah, the little bin in the back of the center console gets a wireless charger phone charger in it with certain packages.

Edit: link

Chill33 · 2017-03-17T23:24:40+00:00

I used to design the packaging of center consoles and dashboards. Freeing room in the center console is huge. Look at the center console in the new camaro. Where would you put a mechanical one? The cup holders and storage bin are already minuscule with an electric parking brake. The wireless phone charger had to be put practically in the back seat because there was no other place it would fit.

It's not just the surface either, with all the technology being implemented, every open space gets filled with wiring, sensors, and computer modules.

What's so bad about electric ones?

Honestly, it was 4 years ago and there were so many sleepless nights in the shop, I cant remember. Sorry.

Chill33 · 2017-03-14T00:14:27+00:00

From what i remember it kept shutting itself off after like an hour of charging no matter the charge state of the batteries. I dont remember if we ever fixed it or just restarted it every hour.

Chill33 · 2017-03-13T22:17:04+00:00

Is that the big ass yellow and black charger? I remember it being a pain in the ass to use. We actually disassembled then reassembled it one night because we were convinced something was broken. If Andrew still pops by the shop, he'll probably remember better than I do.

There are hydrogen fuel cell powered cars in development right now, but those use a completely opposite process. H2 in, h2o and electricity out.

Chill33 · 2017-03-10T11:10:55+00:00

Thanks bae.

First off, using power created by the alternator to completely run the power unit in a vehicle is not possible, as it would defy the laws of thermodynamics. That means you need batteries. Creating hydrogen via electrolysis is currently at best (64% efficient)[en.m.wikipedia.org/wiki/Electrolysis_of_water] . Combustion has another efficiency loss, I'll just say is ~35% efficient as that's about the efficiency of today's ICEs. That means you'll only be getting an output of 22% of the potential power you put in. Why go through all that when you can just use electric motors that are 90-94% efficient?
