Gen 4 prius horsepower explanation.

[I frequently own station wagons with as little as 70 HP. (and have no electric motors)]

Gen 4 has a 98 HP engine and a 27 HP motor. Since they are never at their peak at the same time, the total is 121 HP.

Your Gen 3 has 110 HP total

The Prius c has 98 HP total.

 

Jim,
I believe that the electric motor is actually 50 HP but the battery can't put out more than 27 HP. My AWDe also has a 7 HP motor on the rear axle

I don't know how Toyota comes up with the 121HP rating. The peak engine and motor power probably never occur at the same time.

The hybrid system in the Gen 4 Prius is rated at 72kW (96HP) for the engine and 53kW for the motor (71HP) with the Li-ion battery being able to supply up to 30kW (40HP).

The battery power has been gradually increasing with each generation (20kW - Gen2, 25kW - Gen 3, 30kW - Gen4).

The MG2 motor power actually decreased with the Gen 4 but is now able to support higher road speeds with the engine stopped than previous generations due to its higher rev limit.

This is from document SAE_2016-01-1163 published by Totota in 2016. Gen 4 is P610, Gen 3 is P410)

I suspect you're right. That's why TOYOTA won't post a TORQUE figure on Hybrids - because it's never going to replicate.

 

Correct: all fourth-generation Prius cars use the 2ZR-FXE gasoline engine (1.798 L displacement) and P610 hybrid transaxle and have the same hybrid system combined output, which Toyota quotes as 90 kW (121 or 122 HP). There are three major variations, with basic model codes ZVW50 (Ni-MH battery, 2WD), ZVW51 (Li-ion battery, 2WD), and ZVW55 (Ni-MH battery, AWD-e with the Q510 rear traction motor).

Only the ZVW50 and (starting 2019) the ZVW55 have been built for sale in Europe as new cars, but there are a few PriusChat users in Europe who have ZVW51 models exported from the U.S. or Japan.

The former: they’re quoting the engine output only.

 

My first thought

Concerning Gen4 Prius horsepower, that is correct, there is no 98 horsepower Gen4 prius available. The 98 horsepower Gen3 Prius was called Prius Aqua in Europe and Prius C in US.
For Gen4 Toyota has released a Yaris Hybrid with a 1.5 liter gas engine and total 98 HP...... Toyota Yaris Hybrid 2020 review | Carbuyer.
EU Gen4 equivalent 2020 Yaris Hybrid is slight difference from EU Gen3 2012-2016 Prius Aqua.

All really confusing

It doesn't really matter what HP the ad states as long as it's a non AWD Gen 4 they're all the same.

 

I think it was 138hp. So says the 2013 Product Information sheet I downloaded from Toyota's website.

Not that power matters much anyway; I would argue that consumers generally should compare torque figures, since that will actually tell you the maximum tractive force the car can produce. Since power is a time derivative of energy, it's hard for the average consumer to wrap their head around what power figures mean; they just figure that more is better.

 

You really don't need to know this to understand power. Someone who exercises has more power than someone who doesn't. Your dad probably has more power than your mom and would probably win in a fight. More is obviously better if you want to accelerate quickly. You don't need to really internalize how much power 150 HP is to know that all things equal, if the vehicle was rated at 200 HP instead, it'd feel noticeably faster.

 

Horsepower correlates well with top speed, torque correlates better to 0 - 40

 

If Dad is big,strong, and sedentary, and can clean a 300 lb barbell and then go open a beer can, and Mom can stack twenty 15# feed bags in the same interval, that's equal power.

Even getting away from cars, it's possible get mixed up about (the equivalents of) torque and power.

 

I don't know what it is, but my 2019 is zipppier than the HP and torque numbers suggest.
