When he writes, "we produce 98% of the natural gas we use", I suspect he means that the natural gas comes from wells in the US rather than foreign imports like oil.

Both GM and Ford have also announced production versions of CNG powered HD pickups. But the big news is in heavy duty trucks. Navistar has committed 1/3 of it's output to CNG fueled trucks because of demand from customers due to cost savings over diesel.

The sticker on my Silverado says "Made in Indiana".

All vehicles in the US have had hardened valve seats since the '70s when the move was made to unleaded gasoline.

Chesapeake Energy and 3M are partnering to develop new CNG tanks for vehicles that are lighter, more space efficient, and much lower in cost.

Yes, running silently is a big advantage though this would most likely be used for "silent watch" verses vehicle movement. Of course, this benefit is gained with the disadvantage of increased weight, cost and volume requirements for the batteries and associated support systems. As with all designs, you try to reach…

Fuel economy has always been an important requirement in the design of military vehicles. Reducing the logistics burden of fuel supply is only one benefit of better fuel economy. Volume and weight of onboard fuel, as well as vehicle range and availability are just, if not even more important.

Actually, I think a full time ride would be better because she'd get experience faster. But I think Daytona, along with Talladega, is the worst place to learn, because plate racing is just much more demanding of the driver. But, of course, she's at Daytona only because of the PR value.

Huh? Damn that Stewart-Haas for setting up Danica's car to be the only one in the field with "lift throttle oversteer". Good thing none of the other cars in the field experienced this condition.

Do you get the idea Waltrip has a wicked crush on her?

No bad, but this is my all time favorite.

I'm surprised this wasn't included. Nobody, especially Ford, expected something like this in 1969.

I have a hard time choosing between the 67-68 STP turbines and the 67-70 Chaparrals.

Speaking of Murilee, his Project Car Hell column has been appearing on Autoweek's web site. Here's the latest from last Friday.

Andretti, one of my favorite drivers, never won the 24hrs of LeMans though he competed there many times. He also won 3 Indy Car championships under USAC.
