You know, Bob, that thought has crossed my mind a couple of times. I think back to walking through the one on display at the '03 NYAS with you and Juice, and I think the Sprinter would make a great mobile office or race team vehicle. You could also load it up with servers, routers, other IT equipment etc. and make it a mobile disaster recovery site. I wonder what its towing capacity is like.

I'm a generalist hockey fan but do like fast-tempo teams. I liked the way Calgary and Tampa played all the way in, but I have to admit to favoring Tampa now. ducks for cover ;-) either team certainly deserves it and hasn't had an easy ride in.

NY (Nassau Veteran's Memorial Coliseum) 6/10 to 6/13
Boston (Gillette Stadium) 6/17 to 6/20
Philadelphia (Philadelphia Park - Home of Smarty Jones - a Triple Crown winner tomorrow?) 6/23 to 6/27
Cleveland (I-X Center) 7/8 to 7/11
You've seen the vehicles at the auto show. Now experience over 100 of the hottest new cars, trucks and SUVs on the planet from behind the wheel at the AutoShow in Motion. Test drive the exciting General Motors family of vehicles and then compare them with Honda, Ford, Toyota, BMW, Chrysler, Lexus, Dodge, Mercedes and more too numerous to name.
One minute you're stepping on the accelerator of a Corvette down a speed course, the next you're taking a HUMMER H2 off-roading. If the vehicle can do it, we're going to prove it!
And you can do it all with no pressure to buy, so there's nothing to slow you down. The only thing we want you to do is drive what you like and have a great time doing it. AutoShow in Motion – The world's only auto show where we hand you the keys.

VW's new V10 turbo diesel uses an alloy block, with plasma coated cylinder walls! That's got to be a first for diesels...
The weight-saving aluminum cylinder block enables another important new technology to be introduced—plasma coating of the cylinder walls. This process, developed by Volkswagen and used here for the first time on a production diesel engine, creates a surface layer in the cylinders with a thickness of a few tenths of a millimeter—a few thousandths of an inch—and makes the cylinder walls permanently resistant to deformation and wear

7.5 sick? I don't think so; not for a diesel. Pricey? No question, which unfortunately will mean very few units will be sold here.
Bob
btw, he meant "sick" in a positive way. LOL

They're probably nikasil like most other aluminum blocks have used since the 80s. Maybe it's some new metallurgy based on that.

I think all they do is superheat gas (to 30000 F) with an electric arc, and then use it to deposit coatings (ceramics, metal, etc) on parts (which remain relatively cool in comparison). Pretty neat idea.

It's a metal. Too much friction for carbon or ceramic.

Here's a good article that discusses some of the materials used in the cylinder liners.
http://www.iom3.org/divisions/automotive/news3.htm
"Various materials can be used to produce the coating, especially iron-carbon alloys with various chemical compositions. As the coatings are generally applied using the APS method (Atmospheric Plasma Spray), the coating attains a certain degree of oxidation that has positive effects, since the correct type of oxides are formed if the oxygen content is correctly optimised.
The oxides FeO (Wustite) and Fe3O4 (Magnatite) are to be seen as solid lubricants that improve the tribological properties of the coating and it’s machinability.
It is also possible to apply non-corrosive coatings of iron-based alloys by adding chrome and molybdenum. These coatings are resistant to sulphuric and formic acid when used in internal combustion engines. Adding fine particles of tribologically functional ceramics can reinforce the materials, which increases the compression strength and abrasion resistance and reduces the tendency to scuffing. These MMC coatings have already been tested and are especially suited for high performance petrol or diesel engines."
here's the industry leader in coatings:

besides, a lot of those Tampa players are Canadians. I'm sure when they bring the cup home for their 2 days, the locals won't mind seeing it.

A lot of carmakers are now eying China. I don't ever recall seeing so much press coverage on the Beijing Motor Show.

Ford gave the press a sample to drive around NY at the auto show and it averaged excellent mileage, not bad with press wags behind the wheel.
Toyota has pledged to maintain their leadership. It's a nice green halo to have, people tend to forget that the V8 in the Tundra, LX, and RX is one of the dirtiest engines built today.

And think of it from the mfgrs standpoint: Land, resources, labor - all at rock bottom prices. Emission standards, environmental impact statements? Forgetaboutit.... We spent a week in Nanchang (Jiangxi Province). One of several steel and car mfg centers of 3 million or so. A city jammed with new cars.... China is the place to be!

Plasma has been defined by some as the 4th state of matter. Take a gas and dissociate it into reaction crazy ionic components either thru the use of an RF field, or impact energy transfer (phonons - basically sound energy). The reaction frenzy either creates etching of the target material (the engine block), or deposition of a coating, depending on the choice of gas, tuning of energy to fuel the reaction, directionality of fields, partial pressure in the chamber, etc.
Fun stuff.....
