Thread: Toyota announced big Landcruiser spec change & price drops in USA

While it can and often is said there is no replacement for displacement and I do agree with that statement displacement in itself has nothing to do with longevity.
It is entirely possible to design a 2.8l diesel to produce 80%of 500nm (most marine/stationary engines are rated at 80% max output 100%dutycycle) to last 500,000km or a million km if you like but it's efficiency will be worse and emissions will be worse with its bigger bearing surfaces,thicker rings,heavier pistons stronger block and head etc.
At the end of the day manufactures no longer want to produce an engine or vehicle that will last 30 or 40 years.
What meets the market and the Regulations is fuel efficient low emissions vehicles which is why we have the smaller more efficient engines with low tension rings etc etc
They don't wear out because they are small capacity they wear out because that is their design life.
It wasn't that long ago we we driving Pommy and American shit that made about 6-8 hp out of 2L and needed a valve grind every 30 thou and rings and bearings every 60 and you don't get much more under stressed than that.

If I had cash In hand to buy a new land cruiser tomorrow I would buy the v8.
It can easily be tuned to make 700nm and still last 500,000.....I wouldn't say the same for the hilux motor.

Tho if they wanted to they could build one.
