Of course, If I were Honda I would be working on a 4cyl Accord hybrid also.
I second that.

37.4mpg is very close to 37.3mpg of Road&Track's RoadTest
 
Pacific coast highway: 46.5mpg
Rush hours: 32.3mpg
Mountaineering/high-speed fwy: 38.3mpg
 
BTW,
 0-60mph 7.3s
 1/4mile 15.6s
 
Compared with Camry SE v6: 26.3mpg
0-60 6.1s, 1/4mile 14.6

"It will be embarassing for Honda if HAH gets less combined MPG than Ford Escape Hybrid"
 
It turns out to be true (2 years later). See the real world mpg for 2WD from http://www.greenhybrid.com/compare/mileage/
 
Accord 2WD Auto Hybird - 29 mpg (ULEV)
Escape 2WD eCVT Hybrid - 31 mpg (AT-PZEV)
 
The SUV that is cleaner than a family car. A full hybrid vs. mild hybrid.

"Based on HSD 1.91% power efficiency value, I can estimate that 4 cylinder Camry hybrid can perform like an Accord V6 with 240hp ICE if and only if, Camry hybrid Atkinson cycle ICE outputs 126hp(240/1.91) and electric motors are proportional in power(about 96KW) of the Prius."
 
Toyota even out-did my estimates. TCH ICE makes 147 hp and MG2 makes 105 kW.
 
-----------------------------------------------------------
"Camry hybrid with 4 cylinder engine can have performance of an Accord V6 with fuel economy of a Honda Civic!"
 
It turns out 0-60 for TCH is 7.3 sec vs. Accord V6 7.0 sec and get better fuel economy than the Civic EX Auto (last gen Civic 32/37 mpg, as I made this statement almost 2 years ago).
 
We have yet to see 30-50, 50-70, and top gear acceleartion numbers.
 
TCH peaks power at 192 hp and Accord EX V6 peaks at 240 hp. Peak power say little about car's performance with the introduction of full hybrids.

Please.
 
2 vehicles with equal weight. One has 253hp the other has 155hp. One goes 0-60mph in 6.1. One goes 0-60mph in 8.9.
 
Which one should get better fuel economy? It is a surprise that the numbers are so close.
 
A performance mild hybrid versus a slow full hybrid that weigh the same. Which should get better gas mileage? Obvious to some; a surprise to others.

It is because the HSD system requires the engine to run all the time, even when the traction battery is fully charged! What a waste!

Would the electric motors sustain running at 75 MPH without ICE for two minutes or so while the battery drained?

How do you define "run"? Prius' ICE will always run above 42 mph because how the PSD was arranged. It does not mean the gas is consuming all the time. There are times when I go downhill 70 mph and get 99.99 mpg. For Camry, it might be different since it has additional planetary gearset as a Speed Reduction Unit.
 
If the ICE is on when the battery is full (not really full, only 80%) then only the ICE is powering the car. Otherwise, HSD can use both MGs to consume the battery. HSD can use the battery at any moment on demand. It usually have the battery SOC of about 60% so when you slow down, regen brake can fill it up.

Run means the MG1 always genrated electricty at highway speed whether it is neede or not. If not needed then is converts the MG2 into a motor an power it which then powers the wheels. It is more efficient at highways speeds for the ICE to drive the wheels dircetly without going through a couple of conversions ICE>MG1>MG> wheels. No conversion is 100% efficient and it is like throwing away energy. That is why Honda's IMA systme can achieve better highway than city mileage and the HSD system can not: "highway inefficiency".

P.S.- If you will look back this has already been discussed ad infinitum and you were actaully in the discussions already so I am curious as to your questions ?
