What makes a car more reliable than another?

810 views

On Reddit you always see people saying that old Toyotas are unkillable, or that Lexuses (Lexi?) have a really long life span.

I understand that different cars have different engines and parts, but why should a 1991 Camry have a longer lifespan than my 2013 Fiat Panda?
Besides, there isn’t a different engine on each distinct car make, is it?

Also, I was often told that cars tend to break after 200,000 km. But some guys manage to pull records like the “million miles Lexus” while some cars catch on fire at 30,000km.

Last point: sports car. I often read that people don’t use them not to get miles on the odometer. Do they have a shorter lifespan?

In terms of engine shape, I’ve got a Toyota landcruiser fj80 with almost 250000 miles on it. Part of the reason it’s lasted so long is because it’s using an online 6 I stead of a v-shaped engine. Inline engines tend to have less engine vi ration and it makes them last longer. V-shaped engines require a lot of engineering to balance them to keep them from vibrating so much. There’s a science garage video you could watch on inline 6 vs v6.
