Prius Street Race

This is my 06 vs a couple friends cars. I know some of you will bring the hate so go ahead and bring it on.

Prius is actually not all that slow, it's slow off the line but has good top-end.

I'm so amused. Of course, the trouble is there's not a lot you can do to make it faster - you just stomp it and hope you're faster. With a manual, you can make some slow cars quick (and some quick cars slow) - I beat a decked-out Celica in my '62 VW Beetle.

But that was because he had no idea how to drive.

Oh good god...now somebody's gonna take this to some hot rodding site and they're going to start trolling...been there done that.

I knew it was reasonably quick, I have left RX7s and Nissan Silvias in my wake up to 70km/h going up a slight hill, and I know from the noise they were both trying.
The turbine smoothness of the HSD is deceptive, no jerking no chirping just urging. Constant thrust!

lol... Well that Civic only had 106hp so you were already up on hp and of course we're up on torque as well. 115lb-ft (max) on the Prius... I can't remember how many in that Civic.

What was the battery SOC for each of the race? That'll be nice to know. Also did you have the engine engaged before start?


Also, I'd figured it'll be the other way around, quick off the line and poor top end (given the way the CVT and electric motors work).

It would be interesting to see what one could do to the electric drive piece of the Pri since all attempts to upgrade the gas motor jsut led to better SOC overall.

Little known fact??

You can force the Prius to recharge the battery (although it defeats the principle of being economical since you have to press on gas and brake at the same time). You have to put the car in D and then press down on the brake and the gas and the brakes will hold the car while the engine revs up to respond to the gas pedal input. The best part, the car knows when the battery is getting full and will slowly lower the engine revs until it just finally stops. Although the car might then try to "burn off" some of the extra juice since the car doesn't seem to like having the battery totally full.

There is an initial delay on how quickly the gas motor engages, then the CVT has to turn the gears before the car reaches max RPM (max power).

The prius has effectivly 110hp. For the torque it's hard, the electric motor puts out a lot but because of the reduction gears you don't really see that. I think it has somewhere around 110tq in reality with both motors.

These are the real stats of both cars:

Prius
110hp/110tq
2890lbs

Civic
115hp/110tq
2465lbs

On paper the Civic should absolutely crush the prius, it's got about the same power with a good 400lbs less weight.

When racing I "powerbraked" the prius which revs up the ICE. At the track it has no difference in 1/4 time however it allows me to have a bit better reaction time since I just release the brake rather than push the gas. The CVT is really good on top-end both cars were able to get a car ahead of me or so right off the line, but every time I was able to come around and win.

Some others have commented on this in the past also. This actually slows the car down. The reason is it heats up the inverter and all the electrical components reducing their efficiency. The fact is the car only uses maybe 2-3 bars of battery per race, and usually by the time I've come back up for the next race it's back where it was or better. Basically Force-charging the prius just makes it slower. I tested all of the different ways at the track so I know it just slowed down once I charged it. Full or about 1/4 battery does not make a difference going down the track. When it's in the purple or whatever it does get a lot slower. But it's almost impossible to make it purple while you are sitting like that unless you have the AC running or something.

Ohh.. it's the 2001-2005 Civic.. oops. My mistake. I thought it was a 96-00

I've smoked (not literally) several rice-racer Hondas from the stop light. One guy was revving, so I know he was into it. Of course, I do have the BT plate + Shark fin + Prius side door decals, so my car isn't really stock. That stuff must be good for 20-30 hp at least
