Prius Prime Acceleration

I do not think that is ludicrous.

 

The Prime has the best efficiency of any car available.
To achieve this, Toyota likely opted for gearing more conductive to that at the expense of raw acceleration.

People do like an EV's acceleration, even if the Leaf, which has a 0 to 60 around that of the Prime. Because a motor delivers its peak torque right away, the car feels faster than the ICE one they are use too.

 

I'm not buying it to race anyone off the line. Now, THATS ludicrous.
Quiet, comfortable, a great value, and High Tech. That's what appeals to me.
If I wanted a fast car, I'd buy a P90D with the ludicrous option. I prefer not to spend my money that way.

I would be more concern about efficiency of recuperation during braking. Prime is heavy and has big kinetic energy to utilize.
If I am not mistaken MG1 may assists only acceleration but not deceleration due to one-way clutch. Emergency braking typically takes only a few seconds. For maximum efficiency all kinetic energy car obtained during 11-15 sec acceleration should be consumed by battery in say 3-5 sec. This may require much bigger generator, (say 150-200 kW). It means that in case of emergency deceleration <30% of energy can be recuperated by MG2 (or up to 50% is MG1 will be able to assist)
For maximum MPGs deceleration, if possible, shell be done during the same 11-15 sec

 

I don't need ludicrous speed but I need it to be able to get me out of possible bad situations! A sun 10 sec time would have been nicer.

 

11.3 sec empty! put 5 people and 300 lbs of luggage then it really slow ! like 22+ sec . to 60 mph.

 

You think four people + luggage weighs around 3,600 pounds?

 

it is what it is.

 

I drove a G2 (2004), G3 (2015) and G4 (2016) on the same route on the same day. One spot was a full-throttle acceleration up a steep hill from rest.

The G4 was three miles per hour faster at the top than the other two. The Prime has the same drive train but duel motor in Ev and much larger battery storage.

 

Where you come up with 3600 lbs? Prime weight I. At 3,365 lbs 5 people at 175 lbs =875lbs + 300 = 1,175 total weight est. 4,546 lbs .

 

Watch the Video very closely !
As the guy is reviewing the inside of the car,you can clearly see that the battery is very near to depletion !
Even mighty Tesla S/X cuts the power at that stage and no more "ludicrous-mode" is possible .
Also keep in mind that these vehicles had pre-production stage and software may have not been final yet.

 

That's what it would take to double the 0-60 time from 11 seconds to 22 seconds.

 

I agree. With the highways around here, I would sacrifice some economy for some extra acceleration for safety's sake.

 

i haven't ever had an issue with highway acceleration.

 

In Hybrid Mode, there is no 'dual motor drive' the two motors loin together only in EV mode.

The acceleration (in EV) and the recuperation in braking are both limited by the battery capability and not by the motors. The battery peak output power was stated to be 68 kW (compared to 38 kW of the PiP - 83% increase) don't know about regeneration capabilities but it was improved as well..
