why do cars have so much horsepower?

Not open for further replies.
My guess is that every manufacturer could offer a 200hp V6 engine, but if you drive it in the same fashion as the 300hp version, your fuel economy would essentially be the same. And if given choice, how many customers would choose the 200hp version if they could have the 300hp version for the same money?
 
Careful what you wish for. There are plenty of small cars available today that just barely scrape 100hp, but does anybody commenting on too much HP have one?

OP seem to be ignorant that the car he has, had one of the more powerful engines at the time in the segment, and had more HP than a lot of V8s from the 80s.

By some replies, it seems like "too much HP" really means "more than what my current ride has" because we all know we make the best decisions and it is others that are foolish.
 
I only read the first 20 or so posts in this thread. The answer is actually pretty simple. Horsepower has been selling new cars for over 100 years. Doesn't matter the reason why. More horsepower means more sales which means more $$$$$$ for the automaker.

I like my underpowered cars pretty good. I dream of owning a Mercedes 240D and riding down the interstate at the legal minimum of 45 MPH, puffing out giant clouds of black smoke. No radio. Just listening to that engine. Actually, my truck does a prettt good job at that.
Most people are in such a hurry and drive like homicidal maniacs in their overpowered egomobiles.

Know what's better than both? Driving a fast car fast.

Know what's better than that? Riding a fast Motorcycle fast.

But why do bikes have so much horsepower?

:screwy:
 
I can say that my Club Sport made me a better driver in that with a low powered car simply you can't afford to make any mistakes on the track. Blow a corner and it will cost you for the rest of the lap- at least. Horsepower covers a multitude of sins.
 
Why not? The cars of today are much more efficient than those old boats. I was watching Motorweek Retro reviews on Youtube today and oddly was watching some old wagon reviews from the 80's. Roughly comparable to today's smaller CUV's. Somehow the Colt Wagon and K wagon came to mind. Right around 100 hp and 23-27 MPG on the highway. 0-60 in 10-12 second, 1/4 mile in 18 secs.

I just did a little under a week in a 17 Escape 1.5, AWD. Safer, more creature comforts, 179 hp and got 26 MPG on a long highway cruise, 23 in mixed driving. Not sure about 0-60 but it felt adequate.

I'll take the more power for the same economy any day.

- the 5.0L S62 made 394HP @ 6,600RPM and 369lb-ft of torque at 3,800RPM.

So not only did the S62 make more torque, it made it at a lower RPM.

Some dyno images (poached from the web) to illustrate:



Those numbers are for the pre-'01 LS1. The '01 and later made a max torque of 375 ft lbs, and 300 ft lbs at just 1000 rpm...and the car only weighed 3200 lbs, which made for some fun driving...
The old "real" SBC 350 made some Kick Butte Montana bottem end - I never felt that on the new engines. I know, Ive built more than a few flavours of SBC in the late seventies and early eighties.



AFAIC SBC is dead.

I see you slow dolts on the road - 99% of you.

I'm the guy blowing past you with my wholly inadequate 170 HP 3700LB vehicle.

105MPH on the interstate middle lane today and 35 mph exit at 90MPH.

Brakes seemed a bit toasty when I pulled into my space at work

Yeah you need more HP. And you will do WHAT with it? Nothing.

I was wondering why all those Rogues and Crosstreks were blowing by me at HPDEs.
Good to know!

I'm not seeing those numbers. I see 350HP and 365lb-ft for the post '01 engine

The S62 made north of 300lb-ft just off idle IIRC, BMW used to have a nice dyno graph that showed that but I can't seem to find it.

Regardless, the point is that the DOHC VCT 400HP S62 provided more power than the LS1 stock-for-stock, and did so over a broader power band. Now of course nothing is stopping those technologies from being put on bigger engines either, and reaping the same benefits. My 6.4L has VCT, despite being a pushrod engine.

VCT allows one to move the power band around, fattening the middle so you have a more generous area where performance is near peak. This creates a better driving experience, as it prevents the engine from feeling "peaky" and you always feel like there's tons on tap.

Of course there are limits, you aren't going to make a 1L perform like a 7L, but technology can improve a smaller engine so that it behaves as good or better than one that's lower tech but a bit larger in displacement.


AGREED to most of the above.

But, what did the 'sacred' S62 weigh fully 'dressed' vs. the same for an LSx (not to mention the effect of that valve train on CoG
wink.gif
)?

Most people are in such a hurry and drive like homicidal maniacs in their overpowered egomobiles.


I had a 1980 59 HP 200D that would and did do 135 kmh (80 mph) all day long. No black smoke and all the way on the floor for 600km each way every weekend and on 0w30 A3/B4 to boot.

It was mostly aluminum so I imagine the weight penalty wasn't as bad as it looked, like with a Modular, LOL, but yeah, I'm sure it was heavier, and it also took up a lot more space!

Yeah, I've done 90 in a 240D automatic before. I just took a while.
I guess I want one that is worn out and runs too rich.

I would rather have old size engine and better mileage. what next 350 HP in the same car?
crazy


Because...its fun.
