Drop-off in performance after 20 years?


Recommended Posts

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.

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.

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.

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?
