New 2014 Honda Accord Hybrid

Recommended Posts

Isn't it strange that the clutch that many of us worried would be a problem in fact is ! The HSH had a kluge of a transmission and has faded in the ratings because of it. Hyundai has sold a bundle of them. Honda probably will also. The eCVT Toyota's and Ford's should behave smoothly at 200 K miles just as new.

There are no HP limitations inherent in the design. You design the planetary gear for whatever torque you need to share and the electric M/G's and electronics are designed likewise. They drive trains with electric and electronic systems like these.

The Fusion is smooth when transitioning between ICE and EV, and does not rev when slowing down, it does take a bit getting used to the steady RPM growl since there are no shift points, but after a while you will never notice it.

Toyota/Ford eCVT hybrids drive most like old Buick Dynaflow cars that essentially were single speed transmissions with a huge double torque converter. They had a lot of loss, the eCVT's do not. If you keep your "go" foot steady, the engine ( ICE ) is steady. If you move the foot, the ICE varies. It is not locked to the wheels. After you drive an eCVT for a while, you realize how archaic the other transmissions are.

Your foot and the go peddle call for a given power which the computer delivers. If you move your foot, the power and rpm will vary accordingly. The most efficient way to drive is with steady pedal pressure. Each time you change the pressure, there is a transient period while the ICE seeks a new operating point. This lessens the ICE efficiency during those brief transients and can use more EV assist which is inefficient. Steady pedal pressure is very hard to learn for some people. It requires a high level of spatial relations ability and concentration to judge speeds and closing rates of vehicles ahead of you. In heavy agressive traffic situations other drivers cut in ahead of you if you give then an inch. The solution is to move to small towns in warm weather states.

For those with a moon roof, putting it in the rear up mode with the right rear window cracked creates a pleasant environment in temperatures from 60 -80 º F. without the HVAC on. It's a little noisier but for short trips and tooling around town it drastically improves mileage. I don't hesitate to push "Auto" and enjoy the excellent HVAC when I don't want to fiddle with the HVAC or windows.
