Drop-off in performance after 20 years?

[Gorodish]

My LS400 is 20 at the end of March.  I wanted to see whether there was a reduction in performance over the years - so I downloaded a GPS based 0-60 timer to my phone....and did a couple of standing starts on the (nearly) flat where I join the A55 every morning.

Result - 6.9 seconds.  Which is (I think) what it did straight from the factory.

So - no deterioration. 

Childish - yes.  Impressive - very!!

Next - 155mph test!!!

Interesting...you have Mk3 or 4?

The 0-60 time is always quoted based on Mk 3 not the quicker Mk4. 

Any takers on this? By the time the 4 came out it was competing with other V8s like the S type and it is a tiny bit quicker.

[Gorodish]

Mk4.  Not in PWR setting.  Maybe I'l try that tomorrow!  Like I said - childish - but that smooth as silk V8 revving to 5k + in each gear is addictive.

Mine seems to to be a lot quicker than that

I don’t think it’s childish...it’s what manufacturers test and sell on and motoring press et al report on.

Given Lexus engineering I doubt there is a power decline.

It’s best and safer to have a time keeper with a sat nav for accuracy.

6.9s is the 0-62 mph time so you are a couple of tenths slower

Take care of that old lady! Mine will be 20 years old this month.

Yep so that’s 6.6 to 60?

In all fairness sports mode is needed and ok conditions with proper timing.

Given diesel emission figures I think all figures from cars are sus.

I now have serious supercharger envy!!  Lovely job Steve!

This is why the LS is the best - it's the gift that keeps on giving!

 

I don't think there has ever been a superior engine management set up - so clean that it gives that performance , economy, invariable stumble free running and keeps on doing it year on year.

Aren't we lucky?
