Highest speed driven in Prius

jeff716a · 01-30-2007, 09:21 PM

I'm thinking about trading in my 06 gas Civic and getting a Prius, but I want to make sure it can drive as fast as I'd like it to sometimes. I live in Vegas, but drive down to LA once in awhile, and when I'm alone on long straight freeways, I tend to get up into the high 90's. Can a Prius easily and safely reach 100 without shaking or having problems? Also, what is gas consumption like when the electric motor isn't providing anything? Does it basically get the same gas mileage as a Corolla or gas Civic when you're only using the gas engine?

Top speed of an unmodified Prius is between 104-107. Modified, a Prius went 130.794 at Bonneville.

The prius is a full hybrid. The gas engine can not run without the electric motor. It's not simply a booster. they work together.

with cruise control set at 100mph you will get approximatly 25mpg. it's not very hard to reach this speed. The car rides very smooth at this speed. Make sure your tires are calibrated for a high speed alignment.

is it legal to drive that fast? In some parts of Germany, yes!

I don't know about California...

I believe I did 80-85mph a few times. Ride is OK. However, remember that it is not a high-speed car in a sense that suspension and chassis are not designed for high-speed maneurs like BMW or Porsche. But neither is Civic anyway

Stock tires are not good on wet pavement, so either get better ones or don't try 70+ in the rain.

100 mph isn't even safe in a Civic.

I don't know about that. I've seen a Corolla (93-95) do 100mph down the Coquihalla with 5 people on board.

He didn't say people didn't do it, he just said it wasn't safe.

haha true. But that particular Corolla model runs in P175/65R14 tyres with full wheel covers and a 1.6 litre DOHC engine with 100hp and 105lb-ft of torque through a 3-spd auto.

I did 107 mph once. Prius reached this top speed (electronically limited) going up a slight uphill. It was gaining about 1 mph per sec near the limit. When I got to the downhill section, it remained at 107mph. No shaking... smooth and stable... just more wind noise.

As for your second part of the question... when the power is only coming from the ICE (not from battery but may use the 50kW motor thru generator) going up hill and gaining speed, Prius gets about 35 MPG. It depends on how fast you want to accelerate also. I tested out because my previous car (00' Celica - compact 2,450 lbs) gets 34 MPG on highway. I wanted to know how efficient Prius ICE and benchmarked against Celica. Prius did better going up hill AND WHILE gaining speed!! Oh, the best part is the downhill section where Prius can save more gas. Note, Prius is 440 lbs heavier than Celica.

Overall, here is my MPG average:

Spring / Summer with OEM rim/tire: 52 MPG
Summer / Fall with 17" low profile tire: 48 MPG
Winter with OEM rim/tire: 49.9 MPG (winter gas formula also)
