best torque car

[normality78]

Let's do some survey.

1. Which car got the best torque produce under 1.6cc classification?

2. Which car model got the best torque design inlet manifold?

How to classified? Max torque must be hit before 4000rpm. NO TURBO. ONLY NA

So far to my own reckon is Kelisa 1.0l EJ-DE and Myvi 1.3l K3-VE got the best design inlet manifold

Toyota Vios 1.5l VVTi.

issit the comparison is based on spec? then perhaps we should standardize a rpm of max torque if really want to compare.

 

[normality78]

ok. in this case, lets split into 2 catergory thn. i've re-edit my post. check it out

Why can't we just take the max torque?

 

[zan]

you include NA and forced induction? how about diesel? u want specific statistic based on malaysia market cars?

old waja with 4G18 has good torque output characteristics, my 2 cents

 

[normality78]

why cant just take the max torque? coz there is no point having max torque at not pratical power band

 

[normality78]

well it doesnt only need to be msia market car.

was checking around for numbers when i saw a stock vios which has 196Nm of torque at 4400rpm

lucky Thai people.

anyways back to the topic, i guess the vios gets the cake then.

hmmm i would agree. i drove a vios and its powerful at low rpm. however, im not good with numbers.

just my 2 cents.

I assume we are only talking about stock cars, no?

Stock cars have practical torque bands so taking maximum torque is not an issue. We aren't talking about highly tuned machines here, right?

1/10 scale remote control car with a .21 engine and a 3 speed.
:)

On a power to weight ratio sense, awesome. 0 - 100km/h, also awesome.

:)

 

[normality78]

yup, we r talking about stock car. why not max torque like what i explained earlier on? simple. Car A can develop X amount of torque but at only 6800rpm. Car B can generate lower X amount of torque but it can reach its max Y torque at 3800rpm.

If to compare, no doubt A have higher torque output but at the 3800rpm, it may have much lower torque output thn B.

that's why i only limited till certain rpm coz those r normal power band usage on street

 

[si|verfish]

Ok then.

For under 1.6 litres, my bet still goes for the Vios 1.5 VVTi.

 

[BLaCkHoWLiNG]

normality's car has the most torque!

 

[arrowhead]

wow i got smoked by a vios at the traffic light earlier :shocked: they are powerful :shocked:

 

[zan]

to me, nothing beats sheer capacity power. bigger cc, bigger torque output.

i search wikipedia and

1. Waja 1.6 Campro (S4PH engine) produce 155Nm at 4,000rpm.

2. Toyota Vios 1.5 (1NZ-FE engine) produce 142Nm at 4,200rpm

but i do think Vios is more driveable and feel more power due to VVTI @ flatter torque across rev range

 

[zan]

on the other hand, Civic's screaming B16B VTEC from EK9 Type-R produce the most out of its NA 1.6litre engine. 160Nm but happening at a highly 7500rpm.

wonderful horsepower perhaps with 185bhp@8500rpm

 

[zan]

how to design a basic engine with good torque characteristics?

1. long strokes @ undersquare engine (oversquare if your want high power output)
2. 2 or 3 valves per cylinder (4 or 5 valves are more to high output)
3. in-line engines. Vee engines is a no-no!!

still, a modern engine like 6A10 1.6 V6 from Mitsubishi is capable of putting out 147Nm @ 4,500rpm.

 

[zan]

the best data i can find is from a Citroen 1.6 turbodiesel engine which produced 240Nm. it was used in the ZX, the Xsara and currently the C4 and C4 Picasso

however, this engine is out of threadstarter scope but somehow we can make it a benchmark. any engine below 1600cc able to beat that figure?
