Carmakers Continue to Consolidate

TM and HMC seem to be the only automakers safe to invest in with US listings.

Is Toyota Losing Ground in the Electric Vehicles Race?

The race is for a plug hybrid vehicle. Most people average less than 40 miles a day on their vehicle, but may need to make trips of up to 400 miles on occasion. The long trips necessitate having liquid fueled engine, but the short trips can be handled with an affordable battery (if it can handle a large number of charge/discharge cycles). The hybrid feature is needed to increase the milage of city with its frequent stops by using regenerative braking.

A neighbor has converted his Prius to a plug-in Hybrid and uses a solar array in his back yard to charge it.

Latest on Hybrids: Toyota Yaris for U.S.

A hybrid minivan would be a market leader.

Why the Electric Car Mileage Debate Is Meaningless

Nuclear power plants don't take up any more space than coal plants.

Mini nuclear power plants are being designed that can be placed in remote areas such as Alaska to give economical & reliable power.

Why the Electric Car Mileage Debate Is Meaningless

That ~48% efficiency is a peak fuel efficiency which in a vehicle operating at different speeds and acceleration can be appreciably lowered. I think that plug hybrids should be based on diesel engines but the first one is always a challenge.

Coal, nuclear fuel, and natural gas are priced much lower than diesel fuel which makes a plug hybrid more economical for that first 40 miles or so.

Cash for Clunkers May Cost Up to $45,354 Per Vehicle

I bought a vehicle this year before the trade in program was instituted. So, I missed out on the deal.
The program will take the old clunkers off the road which should be a good thing because the clunkers aren't as safe and use more gas.
Deals like the trade in program are just going to give the dealers more profit.
The deal applies to imports as well as domestic makes. It would be better to have the deal only apply to domestic makes.

Why the Government Is Keeping GM Alive

I owned GM stock until I found out that they hadn't fully funded their pension plan. In the mean time they were paying dividends although they didn't have enough equity to cover their debts.

GM, Ford, and Chrysler weren't on an equal tax basis with foreign manufacturers which could have been partially alleviated by a value added tax.

GM shouldn't have been pushing blue sky hydrogen technology when hybrid technology was shown to work in a cost effective manner.

Six Cars That Represent the Future of Driving

Regenerative braking is what makes the current hybrids attractive. Any future vehicle will have to have regenerative braking with a battery pack and electric drive motors.
Hydrogen is expensive to produce, dangerous, and has a short driving range. Fuel cells(expensive!) are are a better way to convert hydrogen to power than an IC engine.
Plug in power add on to a hybrid vehicle would work for me, but for vehicles that need to travel hundreds of miles per day, that might not be suitable add-on.
Compressed methane would work for large trucks, but passenger vehicles need something more like propane which is much cheaper than gasoline.
Ethanol has delivery problems that could be improved by converting it to ETBE.
Reducing vehicle size can reduce energy consumption, but that might require a second vehicle that can haul more people, cargo, and trailer.

Half of U.S. Consumers Delaying New Car Purchases

I am delaying partly because a hybrid model I want isn't available locally that isn't overloaded with expensive options.

How To Save the Big 3 Automakers

There are many factors that have and are destroying manufacturing in North America. A value-added tax to replace part of the current corporate taxes would reduce the subsidy to foreign manufacturers. A reasonable health care system would reduce health care costs for current and retired employees. If the value-added tax were to be extended to oil, manufacturers would have a more predictable market for vehicles with lower fuel consumption.

The switch to defined contribution pensions, such as 401ks will help since the companies won't be gambling away all of their obligations to employees.

Companies that are in financial trouble shouldn't be paying dividends.

Are Hybrid Vehicles Worth the Price?

Since depreciation is the main expense and hybrids have minimal depreciation, it makes sense to get one now if one can be found that isn't way above MSRP.

Chrysler's Rebadging Plan: Strategic Blunder for Nissan?

If Chrysler can't deliver a hybrid minivan they should just go out of business.
