Toyota Going 100% Hybrid By 2020

autofan1 writes "Toyota's vice president in charge of powertrain development, Masatami Takimoto, has said cost cutting on the electric motor, battery and inverter were all showing positive results in reducing the costs of hybrid technology and that by the time Toyota's sales goal of one million hybrids annually is reached, it 'expect margins to be equal to gasoline cars.' Takimoto also made the bold claim that by 2020, hybrids will be the standard drivetrain and account for '100 percent' of Toyota's cars as they would be no more expensive to produce than a conventional vehicle."

"What the Japanese don't understand" is a hilarios way to start any sentence about automobiles. There are things that Japan has been getting right for over 20 years that GM still hasn't learned.

0% Zero Emissions

[Doc Ruby]

So Toyota will sell no all-electric or other "zero emissions" cars in 2020? No H2 or fuelcell vehicles? Hybrids are better than simple internal combustion engines, but not good enough. Has Toyota and the car industry just figured out that they can avoid the really big change away from gasoline just by getting us all to go "ooh, hybrids - that's good"?

The real win of hybrids isn't the drivetrain, it's rengenerative braking. Storing kinetic energy rather than dissipating it as heat is an obvious efficiency win, since you're presumably going to stop moving at some point.

Really, the other efficiencies of hybrids are side effects of regenerative braking - once you've got an infrastructure in the car to store kinetic energy and subsequently deliver it to the wheels, you might as well use that infrastructure to improve the running efficiency as much as possible.

Now, it's possible that for current hybrids, the overhead incurred by including that infrastructure outweighs the gains of regenerative braking for some driving profiles, but there's no reason to think that will always be the case, since that's an engineering problem, not a physics one.

Other things equal, vehicles with regenerative braking will always be more fuel-efficient than vehicles without. The challenge is to make other things equal.
