HI,
I have just been reading the specifications for the new model Toyotas (200 series wagon and the 70 series commercial vehicles).
The LC200 V8 turbo diesel develops 195 Kw (@3400rpm) and 650Nm torque (@1600-2600 rpm).
However in the 70 series the V8 turbo diesel develops 151 kw of power (@3400rpm) and 430 Nm torque (@1200-3200rpm). Also the fuel economy in the 70 series is 11.5l/100km (combined cycle) but 10.3 l/100km (combined cycle) in the LC200 series.
Does any one know if this difference is just a "chip" or some calibration of the engine or are they two distinct (tehnically different) engines albeit with exactly the same displacement (4461 cm3).
I had always assumed thesenew V8 diesels in both models to be identical but obviously they are not.
Can anyone shed any light on this - if its a chip making the difference can you get the better (more power less fuel) chip from the LC200 for the 70 series?

The 70 series motor only has one Turbo whereas the 200 Series has twin turbos.

Thanks Kev,
I didn't pick that up on my specs sheet- I just checked and it says exactly the same for both " direct injection, turbo charged and intercooled".
But that would explain it - the LC200 is a much heavier vehicle but has more power, more torque and uses less fuel than the 70 series engine. Quite amazing in my books.
Cheers,
Glen

Hi Gronk, the figures are based on an international standard to compare vehicles. It will never translate to what the vehicle consumes in real life.

My (or Hers to be precise) LC200 has only done 3000k's so far and I'm getting 12l/100k.

It's hard to resist putting the boot in.

On the LCOOL site, members there are getting as good as 9.8 l/100k on a long run.

I think they will all get as advertised or better after about 20,000ks.

My single turbo TDV8 trayback gets as advertised (24mpg, 11.8 l/100k).

Good to hear, as reports of 18l/100 were maybe from leadfoots or people not doing an honest apprasial..

My first tank full got 15.8l/100km.

I was pretty pleased given it has done under 500km, 90% in traffic and I can't help putting the foot down a bit.

Boy does this thing go well.

I would suggest that the 200 in more aero dynamic thus giving better fuel economy, may also have different gearing than the 7#

When describing the 79 series trayback, troopy etc you can't use the word "aerodynamic" in the sentence unless it's surrounded by the words:

"really crap" (insert "aerodynamic" here) "qualities".

I agree. It's probably detuned to match the gearbox.

The gearbox is from the manual 100 series and the power and torque figures are too.
