Horsepower vs Torque

[20santafe14]

What is better, high ps but lower torque or low ps but higher torque?

[uls]

city driving you'd prefer more torque

[Egan101]

A good balance between the two will be much better. The key though is at what RPM will the max power and torque will be reached.

[yebo]

torque.

kaya hindi ako bumibili ng honda. taas nga ng rated hp e nasa 7000 rpm naman. sa normal driving 1000-2000 rpm walang kalatoy-latoy. yung civic ng friend ko konting incline lang need pa paabutin ng 3000+ rpm para maka-akyat. sa humps lang nga e 3000 rpm na hahaha! baklitang kotse!

If the torque is 190nm/4300rpm better than 187nm/3600?

[TopEngine]

Power HP = Torque (ft-lb) x RPM / 5252

from this formula alone, Power is dependent of Torque. Now, for example in order to get a 200 HP

If RPM = 6000, Torque = (200HP x 5252)/6000 = 175 ft-lb, it means it is with higher RPM to get that 200 HP
If RPM = 5000, Torque = (200HP x 5252)/5000 = 210 ft-lb, it means it is with lower RPM to get that 200 HP

high HP, low Torque; it means you need a high RPM, just imagine if you have very low torque so you need very high RPM
low HP, high Torque; it means a lower RPM which more fuel-efficient

Higher torque in lower rpm is better. The older Focus TDCi really had good torque figures for a compact car, 320Nm at 2500rpm.

Diesel = torque
gas = hp

Kung same engine displacement, alin matipid, diesel diba.

kaya hindi ako bumibili ng honda. taas nga ng rated hp e nasa 7000 rpm naman. sa normal driving 1000-2000 rpm walang kalatoy-latoy. yung civic ng friend ko konting incline lang need pa paabutin ng 3000+ rpm para maka-akyat. sa humps lang nga e 3000 rpm na hahaha! baklitang kotse!

Maybe the older Civics, City, or Jazz but not the bigger Hondas. Not all Honda's are the same. My old Honda can be rev-happy if I floor the gas but I definitely have enough torque at 2000 rpm. The newer Hondas with the R-series and K-series engines are well-suited enough for the daily commute.

+1 on this!
Yung sa kibigan ko na civic, kapag aatras lang sa hindi ganun ka flat surface(medyo maalon na terrain) Kelangan pa paabutin ng 1000 rpm mahigit.

Depends on the overall tech of the engine, I guess. You have to factor in Direct Injection, Turbo, Compression Ratio. Dami.

Those paper specs are rarely indicative of real-world performance.

Case in point - Vios 1.3 vs City 1.3.

Vios: 85 hp * 6000 / 122 nm * 4400
City: 100 hp * 6000 / 128 nm * 4800

The City makes much more power and a little more peak torque (at a slightly higher rpm). Based on this, it's easy to say that the City will have better performance.

However, anyone who's driven both would say that the Vios feels much peppier in city driving, and even at highway driving (80-120 kph) it doesn't feel breathless. The City on the other hand, takes a lot of revving to get into the powerband. It likes to be shifted at at least 2500 rpm to feel alive.

Horsepower sells cars.
Torque wins races.

[jhnkvn]

Depends on the RPM graph.

"VTEC kicked in yooooooo!!"

[Egan101]

The 1.3L i-VTEC engines that Honda puts on the City and Jazz needs the extra pressure on the gas pedal to make it run at an acceptable cruise. Even the 1.5L still lacks the extra pull when needed at low rpm.

If you want the extra torque, go get yourself a bigger engine. There is no replacement for displacement, unless you go the turbo path.

Even with turbos, displacement matters because larger displacements inherently generate more torque.

Comparing the 3.0V Fort and the 2.2L Ranger, though the Ranger has higher torque (375 Nm vs 343 Nm), the Fort has much more low-end grunt due to the annoying turbo lag of the Ranger.

Too many things to consider...

Which is why an in-depth test drive is best. Some cars aren't fast but feel fast, some cars are fast on paper but aren't in real life..etc etc

It boils down to your needs and preferences. Drag racers and open highway speeders will always go for hp (yo!) but these will get whipped on a mountain road and a technical track by the car with a good dose of low end torque. In most cases, it's the balance between the two that most people prefer nowadays. Test drive lang katapat niyan.

Back in the 1990s and early 2000s, Honda's were referred to as torqueless wonders (taas ng hp pero sobrang bitin sa low end); at least with the newer models, it's less evident already.
