Maybe some company should just come up with a very basic car with something like 50hp that gets insane gas mileage without being a hybrid?

It's called a Geo Metro.

There are times when accelerating swiftly can get you out of very sticky situations.

IMO, a moderately sized car should have no less than 175-200hp. You won't need it most of the time, but the power will come in handy once in a while.

well i drive a lancer with only 120 hp (maybe a few more, due to intake and exhaust)...but it's a manual, so that makes it better, as someone said

i personally think a car should have around 160hp...just for hills and such.

IMHO, on the other hand, it's not the cars we should be concerned about. it's the REALLY BAD drivers out there. you all know what i mean...the ones that make you wanna hit them just so you can jump out of your car and beat them to a bloody pulp for being so stupid

*shrug*

it would depend on gearing for around the town traffic. for highway speeds you'd have to take into consideration the weight of the car

This seems like a misconception to me. First why does more power make you safer? I have noticed that people who speed off the on ramp into traffic aren't made safer by more speed because they have such poor driving habits. Being too agressive, merging in and out of traffic etc...

And with regards to your horsepower specs... All that matters is the power and torque to weight ratio. A small light car with 90 HP canbe quicker than a midsize car w/ 130 HP.

I bet most of those drivers who do have that much power don't even have the capacity to avoid the accident if the need arises. :D

To be honest no car acccelerates quicker with the gas than when it brakes. So in theory braking would get you out of that situation quicker. My $.02

Is this a serious post or are you poking fun at someone?

There are TONS of good reliable, safe cars out there that frequent the highway that have less than 100 hp and they work just fine.

My ~2500 lb Sentra has 115 crank hp which is probably 90-95 whp, and the 5 speed manual really helps merging on the short NYC on ramps.
I imagine it could get by with a little bit less.

I :heart: the 40-42 MPG though.

Just look at some motorcycles. They have low horsepower in comparison to cars, but they still are more than fast enough.

It's not all power, it's the power/weight ratio.

I had a 1989 Honda Civic that had 70hp. The car was a total POS and broke down whenever it could but while it wouldn't win any races, it did manage to get around.
Curb weight according to Edmunds was 2127lbs so it wasn't all that light either.
Truth be told with the way most people drive 70 hp would be more than enough for them.

I used to have a 75hp car and got around nicely. It even made it to 160 km/h (100 mph) on Autobahn.
Anything less would be painful. I'd say ~100 hp is a good number, which translates to a 1600cc engine (~100 cui).

Hmm, and after this, we see that a standard car in europe has engines in the 1600cc to 2000cc range.
OMG! I see a trend.

I don't think 2/3 of the people who posted in this thread even understand what horsepower is.

0.04hp / lb would be the minimum in the US if you plan to use the freeways in urban areas. I would say you need to be able to get to 60 in under 10 seconds to merge safely on a regular basis without forcing right lane freeway traffic to break hard.

Not having any power to merge onto a 6 lane freeway that has an average speed of 70+ MPH is pretty nerve racking.

I'd be scared to death trying to get the gutless 4cyl AT camry I used to have onto the freeways here in Phoenix.
I've never had any trouble merging in my 4cyl AT Camry. I'm more confident merging with that than I am with a 6cyl AT Grand Cherokee. That's not saying that I don't wish for more power every day, but it's enough to get me onto any freeway I've tried to. I much prefer my g/f's 1.8T Jetta for traveling on busy freeways.

I don't feel safe driving in anything with under 180 hp, prefer 200 and up....

Here in MA drivers are very aggressive and many of them have SUVs and feel they own the road, I prefer smaller sporty cars and enjoy having enough uumph to get out of their way and out manuver them in a hurry....I loved my old mustang with equal length shorty headers into an h pipe and then out into two chamber flow master..that exhaust coupled with the 3.73 gears gave the car enough low end torque and had a sound that would scare the bejesus out of most of the SUV driving soccer moms.

What most people seem to be saying is that they want turbo. More power when you need it, good milage the rest of the time, fun to drive, and only the slightest chance to having your engine spontaneously turn into a bale of scrap metal while you're driving. :)

well according to that, my car has 12.4 hp more than it should. but it's right on the dot is you consider the weight of 2 grown adults

That's why they use the Turbo I4.
