General 1.1 Active Eco

Nissan's method of testing engine durability is to rev the engine constantly at full revs, for 24 hours! :eek: Fiat probably have a similar method being Italian!

Nearly all engines will have been tested to destruction at some point by the manufacture.

Ford done one of their engines, started it from cold, throttle wide open, and just left it, without full cooling capacity, and it ran at full throttle for three and a half weeks before going bang. Now that is one durable engine! (can't remember which one it was though :eek:).

Must have been the 1.2 in the new Ka! ;)
 
ford tested the st 2.5 five cylinder engine (which is actually a volvo lump) for a whole month at full revs until it started to fail and they calculated that it was the equivalent of 140k i think. it was on a 5th gear road test.

the engine was at constant revs though, the most damage comes from the engine changing speed constantly

merc when testing the amg engines simulate the vehicle going around a race track which is probably one of the most abusive enviroments for an engine

rover tested the k series engine at 14,000 rpm for over 2 weeks

from the tests they work out servicing schedules.

and another thing bmw do million mile tests on some of their engines, they did one on a 325i (petrol) where the vehicle is driven constantly for a million miles, they do normal servicing that they would do on the publics cars and when they stripped the engine they found it had wear that was within manufacturer specs

Sounds like marketing speak to me :)

How many times did the k series engine get HGF over that 2 weeks btw? :ROFLMAO:
