I have no clue of how much torque my car has. I know it has 187 horsepower, but that's about it. This article says I have an electric motor capable of 296 torques, but with the synergy system only 199 torques.
2.4L Inline-4 cylinder 2AZ-FXE Atkinson cycle gasoline engine with 147 horsepower and 138 lb-ft of torque
650V electric traction motor with 296 lb-ft of torque
NiMH 245V traction battery with a maximum output of 40 horsepower Hybrid Synergy Drive system with 187 net HP and 199 net lb-ft of torqe"
Does 187 hp give you enough "pep" to merge onto throughways or whatever they're called back east? Does the car do OK on hills? If so, what's the concern about torque?

I find the power to be adequate for those situations.Would love the power of the 3.5L but it's ok.

yes. but you have to be not afraid to use that power.
Oh, I have no hesitation summoning power when I need it -- like when I'm driving my 268 hp, 6-cylinder '07 RAV4. It'll out-run nearly anything on the road from a standing start and reaches the speed limit (and beyond) very quickly when merging onto our freeways. But mostly I hold that power in reserve and try to accelerate smoothly while keeping the tach at no more than 2000 rpms, so as not to waste gas.
I drove on the Interstate in upstate NY enroute to Vermont decades ago and I recall that the road was called a "throughway." But as I say, that was decades ago, so my recollection is fuzzy now.
aptos, then buy yourself 07 Accord Hybrid with V6. you will have around 260 ponies as is, plus hybrid drive that is said to be superiorly smooth to HSD. not a record breaker on mpg, does around 30, but that's much more than Camry.
I was all hoofed up to buy 08 model, but they discontinued hybrid Accords as of that year. unfortunately, i do not fit well into 07 model. it's much better in 08, but bummer...
but hey, for a TopGear type you sound, simply get QX45 or Cayenne... cuz that uphill race i did, dropped mpg by 5 miles to a gallon in 10 seconds. so, if you'll drive it like you mean it, it'll be around 28 average anyway...
Ukrkoz:
You cannot just combine the peak output torque of each motor and call it a total. Doesn't work that way.
Partly because the peak values occur at differing RPMs
Partly because of the "transmission" the two motors do not put power to the wheels at a 1:1 ratio, meaning one motor helps more than the other.
Partly because maximum power output for the electric motor is limited to the current that can be provided by the battery
And finally because some of that current is used in MG1 not to move the vehicle, but to provide the resistance that makes the Engine and MG2 turn at the correct RPMs for the current road speed. This is lost in heat energy. It's not much of an inefficiency, but for any electric motor, it's there.
Daniel: Toyota doesn't publish any official torque specifications for the combine hybrid powertrain because of the complex interactions at work. The only way I know of is to do it the old fashioned way, take a car (with a fully charged battery) onto a Chassis Dyno, and measure the output at the wheels. Then you'll get a torque output at the wheels.
Problem with doing it this way is you'll exhaust the battery fairly quickly. Probably before the run is even over. But it'd give us an instantaneous starting number.
Does anyone know of a Dyno run that has been done on these cars?
kytann, you are mostly right. with due respect, though, you also do not know how much of combined torque and hp does HSD put out at hard to the floor acceleration. i agree with you, simple combination of the two is probably a simplistic approach. but that's the one that is touted everywhere. indeed, until it's dyno-d - it is an idle discussion, as everyone else says that power/torque are combined, no one says to what extent. Toyota will be the last one to dis-vale this.
keep in mind. ICE has ALWAYS had max torque/power at high end rpms. look at the specs above. 190 torque AT 4500 RPM. the curves for ICE and MG highest torque match. of course, this is an idle assumption either, due to variables that you mentioned. we do not know, they do not say.
i bet ya ton of money, the very moment someone dynos TCH and put up some decent numbers, everyone else will go out there, step on it - and fry many HSDs. 100 000 miles warranty, he-he...
also, here's food for thought:
Most HSD systems have batteries that are sized for maximal boost during a single acceleration from zero to the top speed of the vehicle; if there is more demand, the battery can be completely exhausted, so that this extra torque boost is not available. Then the system reverts to just the power available from the engine. This is a big difference in performance: an early-model Prius can achieve over 90 mph on a 6 degree upward slope, but after about 2,000 feet of altitude climb the battery is exhausted and the car can only achieve 55–60 mph on the same slope (until the battery is recharged by driving under less demanding circumstances).
and i am living proof to this, as i got mine from 60 to 110mph in a heartbeat on 6 grade. i KNOW that motor picks up, i can HEAR and FEEL it. it is not supercharger, or turbo, but it is a very formidable boost, combined with very well designed IVVT engine. this car is THE ONLY car we own, that i dare to pass others with, on a 9% uphill, serpentine, on my way back. and we have 3.0 IVVT V6, 5.3 Vortec V8. no match.
As to the torque, if you still think your car has 300+ ft-lbs, I challenge you to go for a test drive in a different vehicle with a reall 300+ ft-lbs of torque. Like a Mustang, and floor that engine. Night and Day difference.
no point. just specs. finally located them in single sheet.
actually, I am grateful you brought this up, Kytann. Thank you.
I rest ashamed. "combined" does not always means 2+2=4.
I agree with you that it is virtually impossible to say anything about numbers for this car performance, due to unknown high end torque. Toyota refuses to speculate. torque is torque, but it's OK.
Fellow who started this thread wants to put CAI on his Camry. CAIs, even if they work, are high rpm end devices. Camry sounds like low low end hp/high high end torque. I think, the only real way for him to improve low end performance is supercharger. They pick up right away.
Kytann, thank you once again.
