We would never get to know from the certificates, whether they were tested last year with the THEN prevailing standards or this year using current standards.

(Pssst.. If both BSIII and BSIV Innova were to be tested according to the new BSIV standards, then the BSIII Variant has an FE lesser than the BSIV Variant by about 0.06 kmpl.)

Need to wait for actual owner reports.

Hi,
Where can I get the BS IV Std FE data for both BS III and BS IV models

Agree,
I am not trying to say one way or the other. All I am saying is that adding an intercooler does not mean you will automatically get higher mpg. Especially when there are multiple conflicting effects involved, the turbo has to face

A. Additional resistance because of the intercooler headloss
B. Cooler air from the intercooler reduces downstream backpressure (and hence decreased resistance)


A and B Are conflicting in nature and after taking into account the change in piping to accomodate the intercooler as well as maybe a different overall exhaust design, there are too many variables to say one way or the other.

Appearing in 2001, the 2KD-FTV is the 2nd generation of the KD series of engine with a smaller 2.5 L displacement.

The displacement of this engine is based on the previous 2 L engine. Bore remains the same 92 mm but stroke is increased to 93.8 mm. Like the 1KD-FTV, it also has 16 valves and is a DOHC engine with a turbocharger and intercooler.

It produces 102 hp (75 kW) at 3400 rpm and 191.7 ft·lbf (260 N·m) of torque at 1600-3600 rpm without an intercooler or 120 hp (88 kW) at 3400 rpm and 239.85 ft·lbf (325 N·m) of torque at 1600-3600 rpm for the intercooled version.

However, Toyota Thailand has added a new variation of engine with variable nozzle turbo (VNT) installed and intercooled. Thus increase the horsepower to 144 hp (106kW) at 3400 rpm and torque of 343 Nm at 1600-2800rpm.

Compression ratio is 18.5:1. Redline of this engine is 4400 RPM. This engine also uses D-4D Common Rail (Common rail direct fuel injection ) technology.

Now lets start drooling..

Why is Toyota hiding the revised power figures for BS4 version? Waiting for Aria to be launched!!

[karpusv]

I do not think the objective would be to hide the FE figures. Its just that different standard yielded different FE values. And they just stuck to it. There probably is no point in trying to say that the BSIII variant has an FE of xx.xx kmpl with BSIII standards and yy.yy kmpl with BSIV standards.

That would lead to a lot of confusion among customers who bought vehicles last year and this year.

Ideal way to handle is to let the prevailing figures remain. As and when ne figures come in for ne technology, just declare those.

from what u posted earlier, the innova didnt have 260nm of torque but 200nm.

The automatics have a different tourque(260nm) but a smaller power band.

see Toyota - Innova

but the auto isnt available in india hence i corrected him.
