Re: CNET editors' hybrid car buying guide
Only got through the 1st few sections, but some very baisc errors:
"Just about all hybrids use regenerative braking, a system with generators placed on each wheel to send electricity to the battery pack when the brake pedal is pushed... that hitting the brakes is actually good for the car, as opposed to the generally wasted energy from braking in a gasoline-only car."
1) A false impression that there are windings on the wheels or brakes themselves. All regen comes from running the motor(s) as generators. The motor is nestled up with the transmission, NOT the wheels. Only the HH/400h have additional motors on the (rear only) wheels (do they even participate in regen? I thought they were traction only).
2) Braking is still never 'good' for the car- its still better to coast, using all your built-up kinetic energy in the most efficient manner: actively moving the piece of steel down the road. ALL other energy exchanges (ie storage) are less efficient.
...and I'll ignore the HAH snub in the reviews
