Hopefully you are all getting your news elsewhere by now, but just in case I thought I'd point out that we're in the final stages of the AXP now! Go get some news: Autoblog Green, MSNBC, or the Progressive Automotive X Prize site itself. Be sure to check out the Team Standings. For your edification, here is a list of the teams that remain in contention:

Mainstream Class (Two vehicles, one team)
· Edison2, Very Light Car #97 (Charlottesville, VA), Internal Combustion Engine
· Edison2, Very Light Car #98 (Charlottesville, VA), Internal Combustion Engine

Alternative Class - Tandem (Two vehicles, one team)
· X-Tracer, E-Tracer #72 (Switzerland), Battery Electric
· X-Tracer, E-Tracer #79 (Switzerland), Battery Electric

Alternative Class - Side-by-Side (Five vehicles, five teams)
· Aptera, Aptera 2e (San Diego, CA), Battery Electric
· Li-ion Motors, Wave II (North Carolina),...

For a long time I've been telling myself that I'll get back into this project, that I will update the car pages, research the new teams, etc. But it's finally time to admit that that isn't going to happen. Today I removed the prominent link to the X Prize Cars page from the column to the right of every page. The information therein is now quite old, many of the teams profiled have dropped out, and many others have changed significantly. I've felt for quite awhile that that page was more misleading than helpful, and today I retire it, without much hope that I will renew it before the prize is awarded.

On the up side, the teams page at the auto x prize website is actually not bad. And some other media (like new scientist) have done some decent coverage of the teams.

I'll probably still post stuff here occasionally, and I will post the winners of the prize, but if you're looking for good coverage you'll find the autoblog at xprize.org to be better than mine going forward. There are also occassionally stories on the Auto X Prize at ...

At a press event at the Auto Show in Detroit (pictured), the PIAXP team unveiled the new Competition Timeline, still showing the same September end date. But, in what I had actually come to suspect was going to happen, they have removed all excitement from the prize: there will be no race across Manhattan, no race between Vancouver and Seattle, no race at the Indianapolis Speedway, in fact no public races at all!

What is left in the schedule is some shakedown safety testing, some "closed door" track testing at the Michigan International Speedway (MIS) -- where "speed will be important" (can you hear the excitement) -- and finally some dynamometer testing. The big opportunity for the public will be a one day open house at the MIS in July, although apparently this will focus on the DASH+ high school student competition ("design the dashboard of the future and you can win!"), and only have a few of the PIAXP cars present.

That's not what I signed up for, and I imagine many of the recent big team losses are related to this - surely the teams had inside knowledge on the...

Stuff.tv exclusive: Tesla pulls out of Automotive X Prize, they intend to focus on moving the Model S towards production instead. They will actually still race the Model S in the "Demonstration Division" of the Automotive X Prize, meaning that it will race along side the other cars, but will not have a chance to win the money, or be held to the same standards (esp. regarding MPGe). We can speculate forever about why they withdrew, but you have to wonder if they were measuring their efficiency and realized that to compete they were going to have to drive quite slowly. Being in the demonstration division means they can drive it like a bat out of hell, dusting the other teams, but getting only 50 MPGe. For a company that makes all of it's money to date selling sports cars, it's probably an important PR consideration to always portray your vehicles as fast...

A quick update on the Automotive X Prize. Many more teams have dropped out: Design Judging Complete: Over Half of All Entries Eliminated. This is actually expected: in the final stretch now, many teams are probably realizing that their car just isn't going to be finished, or just isn't working out (and thus won't be competitive). The image above shows the teams map from July (left) and December (right), a visual illustration of how many are gone. The teams page now lists only 42 teams.

In early November, the Automotive X Prize people hosted a three day "team summit" gathering, where teams got a huge download of information and requirements. This information included safety information, background on the Guidelines, help with PR, etc. They now face some stiff deadlines for some deliverables: Team Summit Day #1 - Three Deliverable Periods Begin December 15. Team Summit Day #1 - Teams Get Schooled in Competition PR and Social Media.

Aptera had a big shake up, and won't be shipping cars until late next year (if ever). The founders have all been booted, they are down to 20...

As our teams going through the process know quite well, the guidelines in this first phase have been very strict. We've asked teams to probe their viability before on-road testing begins in the Spring. The priority during this phase is to ensure that all teams understand the criteria, that entered vehicles meet or exceed the criteria, and that teams appear capable of building a production intent vehicle to these standards in time for formal vehicle challenges. No small feat for any company.

Thomas pointed out in a comment to my last post that team numbers continue to fall: I confirm his count, there are only 73 listed now. So clearly the rigorous requirements are having their effect. At one time I considered starting my own AXP team, but it only took me a couple of months of doing some analysis to determine that I didn't have anywhere near enough time, energy or money to properly compete - building a car is expensive hard work, let alone building one which is capable of 100 MPGe and is...

When they originally revealed the official teams, on April 7th, 2009: 111 total, 106 listed and 6 more remain confidential (don't ask me why that totals 112, I just report 'em as I sees em)

Now, August 20th, 2009: 90 listed, meaning a change of 16 from the prior list. Actually 19 teams have vanished, and 3 have suddenly appeared. These three could be name changes (although not simple ones - I already sorted away 4 of those), or it could also be some of the 6 teams revealing themselves.

Among the list of vanished teams: Linc-Volt, Kinetic Vehicles, MDI-ZPM, Physics Lab of Lake Havasu, Myers Motors. In my opinion some of these teams represent real losses - no doubt there are some people who have quite the story to tell about why they dropped out. Others probably realized that their chosen vehicle would never achieve 100 MPGe. Several of the vanished teams are actively continuing their efforts, they just are not focusing on the AXP anymore.

Teams that have appeared: All Power Labs, Apet-X, Porteon. I actually remember Porteon from before, so it's kind of strange that...

MAX Update No. 32: Why We Resigned from the Auto X Prize. I'm sorry to see Kinetic Vehicles leave - they were a great team with a great vehicle. Their reason for leaving?

But lately, this competition has been interfering with our goal for MAX: a high-mileage car you can build on a budget. The final rules have no place for a DIY car, and preparing MAX (even on paper) for factory production -- as in 10,000 cars a year -- has been sucking up our resources like you wouldn't believe. In the last year I have literally spent more hours filling out X Prize Foundation paperwork than I've spent developing MAX, and MAX has suffered for it. Instead of working on streamlining to improve the car's gas mileage, I've been writing business plans and tech documents and getting price quotes, for every single part in the car. Imagine trying to figure out the cost of 20,000 windshield wiper blades to be delivered in five years, etc., etc., etc.

This is evidence that the balance between business plan requirements and automotive engineering is currently on the business plan requirements, and this...
