Been searching for information about the upcoming Kia Forte/Cerato hatch, and came across this snippet of information:

The Kia Forte 5-door EX comes standard with a 2.0-liter GDI powerplant producing 173 horsepower at 6,500 rpm and 154 lb.-ft. of torque at 4,700 rpm. During durability testing, the engines are run 300 continuous hours at redline under full load then for an additional 20 hours at 10 percent above redline under full load.

That's nearly 2 weeks at redline!

Thanks for the link (I like the wheels)

That's very impressive! It goes to show how much Hyundai and Kia have improved when they're engines are being pushed beyond everyday conditions.

True, but sadly only a partial test. Cold starts & heat / cool cycles do more damage over time, than continuous running. Agreed, that it does test the mechanical operations though.

Makes me ask myself what oil is inside that engine

As a former SAAB entusiast and driver, I have to point out one of the best durabillty tests performed.

When SAAB launched the 9000 in 1986, they invited VW, BMW etc to participate in an endurance test at the Talladega raceway in Alabama.
Of course the other brands turned the invite down.

FIA picked out and sealed 3 standard 2.0 turbos straight from the factory before they were flown to Alabama.

The cars were driven flat out for 20 days and nights, by 31 different drivers, doing 100.000 km/s each.

Now thats durabillity testing.



In 1996 they did it again with the SAAB 900, this time driven by motor journalists.

i wonder how many failures they get??

i doubt many engines love constant rpm and load!

i doubt many engines love constant rpm and load!

I doubt an engine would love anything more than constant RPM and load. If this is the performance expectation, then design can be optimised for efficiency and a very long life. However, as long as normal function includes coping with variable RPM and load, it's a case of 'use or lose it'.

My bad, I missed the comma.

 should have read 'i doubt many, (would have blown up) engines love constant rpm and load'
