That's what I always thought but at the same time I've heard they will start to seize at around 8-10 years depedning on the driver. My mechanic friend told me that and he is in love with Chevy and a foreign hater so he really is just a biased opinion but it doesn't hurt to ask. I've never driven or know anyone who has an Audi so I'm skeptical about the cars. Anyone know anything about em.
The fact of the matter is that die-hard Chevy guys (and pretty much most American car fanatics) have absolutely no faith in imports, four-cylinders, turbocharging, variable valve timing, or pretty much any modern technology used to replace anything from the OG musclecar days. As a side note, a woman who worked in my building was apparently a big Camaro fan, and upon finding out that I was into cars, she stopped by my desk and asked me about cars. I mentioned that I had heard that the upcoming Camaros were going to get four-cylinders as the base motors (as opposed to a V-6), and she immediately scoffed at that and said, "No four-cylinder belongs in ANY Camaro." But little did she know that the turbocharged four-cylinder (a GM product itself) in question is the same 260 hp, 260 lb.-ft unit that powers GM's Pontiac Solstice GXP and Saturn Sky Redline sports convertibles... numbers that not only surpass (by far) every six-cylinder to ever be in a Camaro but also even the V-8s to power the third-gen Camaros up until 1992. Even the LT1 that powered the original fourth-gen Camaros wasn't too far ahead of the new four-cylinder, which is roughly a third the size of that motor while only having a 15 hp deficit.
So what I'm getting at is that such American gearheads usually don't have much to back up their claims and beliefs, which are based on what may have been the truth over 20 years ago. I don't know too much about the durability of Audi turbos, but my mom drove a 1985 Mercedes 300D Turbo Diesel (a German product like Audi) for 20 years before selling it, and it was still running just fine on the original turbo. I'm sure that the turbo on a German car isn't a huge thing to worry about.
