A cabriolet, van, and crossover/SUV are on the menu

Tesla Motors CEO Elon Musk has nearly succeeded in bringing his company public, despite personal financial issues that have prevented him from pouring more venture capital into the firm.  The initial public offering was announced in late January, but is on the verge of completion -- possibly coming as soon as next week.

This will be the first major IPO of an American automaker since Ford Motor Co. went public in 1956.  It comes at a time when Tesla is phasing out the first generation of its high-end luxury roadster, and preparing to sell an entry-luxury sedan, the Model S.  Tesla also recently received $50M USD from Toyota to help it develop electric vehicles.

One of the biggest dangers of an IPO is underpricing.  Many IPOs have been underpriced over the last several decades, leading to companies missing out on a large amount of vital revenue.  To help prevent that Tesla is holding its Road Show, going before heads of top Wall Street investment institutions to try to convince them how much the company is really worth.

In a slide #19 of an impressive Road Show presentation delivered by Musk, he reveals a trio of upcoming all-electric vehicles.  The first up is a hot new cabriolet (hard-top) design.  The model seems like a direct response to Fisker's Karma S "Sunset" convertible.

Also incoming are a van and SUV/crossover.  Both have a lot of curves and look kind of bulbous.  Whether you love or hate the designs, you have to admit, they would stand out in a parking lot.

Musk also revealed other intriguing tidbits in the presentation.  Among them, Tesla Motors will be adopting liquid cooling for the high power electronics used in its electrical vehicles.  Liquid cooling, commonly used in gaming and high performance computing, can be even more effective than forced convection and could allow for higher performance and longer ranges.

Tesla also plans to liquid cool its motors, starting with the Model S.

The full Road Show video can be watched here.

Tesla plans on offering 11.1 million shares of stock.  It is hoping to sell them at a price between $14-$16 USD, raising a target total of around $167M USD

Remember the skateboard?

This looks exactly like the proposed common drivetrain (they called it the skateboard) GM showed off five or six years ago and then did nothing with it.

Thats really neat, nice to see a startup company that is going to go places in the future ( if it catches on ).

Sadly the electric vehicle has existed since 1910! The only thing we need now is research and development for new battery technologies that can store 100x the voltages in the same performance package, similar to CPU die shrinking. Then we will have EV's that coult possibly have 1000 mile ranges on a single charge. But i think technology like that will never be available even if it does exist because i don't think it would agree with corporations pocket books since 99% of all products (yes even your vehicles) are produced with planned obselence in mind. Pity.

Nah. They'll release them, it will just be at a cost that most DTers won't pay (more than $20k USD).

By 100x the voltages, I think you mean 100x the charge. That is just not going to be possible. It takes protons to keep electrons from flying off, and that means heavy metal electrodes or else very large sizes.

So it may not be possible to create a small light weight battery, but even a dense heavy battery would be OK. Hey, they work in cars now. The problem is that the charging cycle of current batteries is way too long. A Tesla with only a 100 mile range would be bearable if it could be charged in less than 5 minutes. But a 100 mile range with an 8 hour charge cycle is just not a feasible replacement for many people.

It doesn't work for the people complaining either cause they haven't bought any. But these people are MORE than happy to spend the money of the people that CAN buy them.

But can't things like Carbon Nanotubes store more protons like little carbon nanotube bags they are trying to develope? I believe even in the 1950's / 60's they even thought about putting small nucliar reactors on vehicles. Talk about being innovative. unlimited range, cool! But have an accident and have a meltdown.

Also I wish i could remember the name of the company that developed a battery that charges to full capacity in under 40 seconds. A regular AA or D battery. Being able to charge a full Lithium battery pack in under 40 minutes would be great.

True, however, that was a fuel cell powered car.

That's what I was thinking, wonder if GM is going to hit them with a patent lawsuit.

Liquid cooled electronics?

I can understand the motor being liquid cooled, but what part of the electronics require cooling? Most circuitry can get by with passive cooling and when you resort to watercooling, it generally means components are on the bleeding edge and likely to fail if the watercooling system fails.

They are throwing around a lot of current from those batteries. Until we get the superconductor thing worked out, that equals heat. I suspect it's for the motor controls circuits.

Probably the IGBT's (Insulated Gate Bipolar Transistor) which do the conversion from the high voltage/current DC from the battery to AC used by the motors and vice versa. Electric vehicles, while very efficient compared to gas, are still not perfectly efficient (I hear around 80% from battery to wheel) so there will be a lot of waste heat from the power electronics.

Exactly. There's a big difference between a small, limited duty cycle motor/controller in a hybrid and a continuous duty cycle motor/controller in these vehicles. My company has developed a number of large current brushless DC motors for aerospace applications, and that alone is a task, not even considering the battery problem.

The people who think people who are trying to keep this technology down need to take off their tin-foil hats and realize that we're pouring billions into this and we still don't have a product that works for most people, and it's doubtful that most of the billions we're pouring in are really doing much except helping guys like Musk fly around in his private jet. Fundamentally, the best product we can make, which is expensive even with large federal subsidies, isn't good enough. Sure, a 100 mile car works for commuting to the office and home for many, but most of us take trips on the weekends well over 100 miles, which means only one of these vehicles per household in the best situation. Even considering a 2 car family, if your wife takes the internal combustion vehicle somewhere, you're now tethered to your house. Realistically, it just isn't even close to being there for most people.

Right now they're toys.

I looked into using a DC motor to do a conversion in my old Ranger. That thing would make a lot of heat also since you are stepping the voltage up from 12V in the batteries to near 500V at the motor. The resistive circuits for that will get quite hot along with the motor itself.

"Tesla Reveals Three New Upcoming Vehicles in Preparation for IPO"

Jason, this was one of the worst title's I've seen you write.

#1. Telsa didn't reveal any new models or vehicles. They made some sketchs! At least they had a concept "CUV" recently... but the other models? I haven't heard of any plans, concepts, models, etc. A sketch is not a model reveal

#2. The IPO business makes absolutely no sense. No faster way to mess up your IPO than making major changes during the process.

Please change the title... here's a fast one

Musk is going through a difficult divorce and its likely that a chunk of this could end up in her pocket.
