finally, finished reading all pages in this v2 topic. huhuhu...
info regarding comparison between pc and vios performance,
some said pc better and some said vios better. so, i just assume both are about the same, might felt differ due to individual factors.
one more aspect i didnt find anyone discussing it (or maybe i missed it), between vios and PC, which one is more silent in cabin, and which one is better handling at both cornering and highway high speed cruising?

Friend
Safety first, others secondary. Vios has no traction control and no stability control, only 1-2 airbags. Find out yourself how these can save life. Engine performance wise,
Max torque:
Vios = 141Nm
Altis 1.8= 173Nm
PC = 169 Nm
Performance wise, PC is about the same as Ailtis 1.8, provided the battery is sufficiently charged, other wise, it is just like Vios, I.e 1.5 litre engine

You will feel vios powerful because of conventional 4AT super-ect, you will feel PC no power because of e-cvt , CVT just too smooth untill we can't feel any power and feel want to sleep, but in real world no matter 0-100, 110-170kmh , PC is faster and more powerful , the traction battery+motor torque is already 169nm compare to vios maximum torque 145nm.................because of eco car characteristic(pc dont have sport mode) and ecvt, we want full power then have to floor the pedal till end , that time you will feel PC is worth for $$$$ ........because you will get 1.8L car max power but only 16-18km/L low FC

Prius C overall power output is just 99 HP, the 1.5L engine is not the normal otto type engine, it is
Atkinson engine which has better fuel efficiency but come with lower power output, 1.5L Atkinson engine is same as 1.1L normal otto engine output.
What make Prius C pick up faster is the motor, which has 169 N.m torque at very low rpm, this is the main thing that wins most of the petrol car. however, since motor is powered from traction battery, if you want good pick up, traction battery level must be more than half.
My 2 cents on performance of PC vs Vios.
Vios 1.5 L engine, max output 109 PS, max torque 141 Nm. Easy, just engine.
PC is more complicated because the engine and motor interact with each other to produce total performance.
PC's max output
Although PC is using 1.5 L engine, it's running on Atkinson cycle, producing only 73 PS max output, which is way below Vios' max output (+1 to Kiding). Thus, hypothetically, if PC's motor or battery MATI, Vios will definitely outrun PC.
But with combination of the motor with appropriate battery level, the max output rises to 101 PS.
PC's max torque
This is lagi complicated, due to the eCVT compared to Vios' AT. Anyhow, the PC's electric motor generates more torque than Vios' engine - 169 Nm vs 141, not to mention the influence of engine's 111 Nm. Even the PC is heavier, the torque:car weight ratio still beats Vios (+1 to jscyl1980).
So,
PC max torque > Vios
Vios max output > PCWhich means,
PC ACCELERATES faster than Vios (0-100 - 10.7 sec vs >11 sec); eCVT makes NO jerking acceleration, therefore smoother acceleration which leads to MISPERCEPTION of "no power to accelerate" (+1 to jscyl1980).
Vios' top speed higher than PC (this is theoretical, I dare not to experiment on my own in real life), thanks to PC's eCVT, PC's max 2nd motor generator RPM = wheel RPM, that's what some people say PC has 1 gear only.
BY theory, you can make use of PC's excessive max torque to increase the top speed by changing to bigger tyre, but this will sacrifice your acceleration. IF any of you know how to do the calculation, maybe you can switch the tyre size to tune PC to higher top speed and at the same time keeping faster acceleration than a Vios.
Conclusion, as a normal street user, I'll still say PC performs better than Vios because faster acceleration is more practical than top speed.
