Car engines don't really last that long. If you assume that a car travels at an average speed of 25mph (probably about right these days.) then 25000 miles equates to 1000 hours of running. 100,000 miles equates to about 4000 hours. There are about 9000 hours in a year, so 100k is less than 6 months continuous running.
The top-of-the-line model was renamed the Q7 TDI Premium Plus, which was only available with the 3.0L TDI clean diesel engine. The Q7 Hybrid, which is a plug-in hybrid version of the Q7, was unveiled at the 2009 Frankfurt Motor Show. How Long Does the Audi Q7 Last? So how long does the Audi Q7 last?
While offering authentic sports car performance, the Audi TT features a high-style interior and seamless integration of high-tech. It was the new century, and Audi wanted to wow North American customers. The new TT was introduced, a tiny and attractive sports vehicle with a 180-horsepower turbocharged engine.
The third and final reason why diesel engines will last longer than gasoline engines is in how they are used. A diesel engine will push about 1300-1600 RPMs vs. a gasoline powered engine will do 2500-3500 RPMs. That means a gas engine is doing roughly two times the amount of revolutions per minute than a diesel engine.
The BMW X5 can last on average between 150,000 to 200,000 miles, this is dependant on responsible use, conservative driving and proper maintenance. Based on driving 15,000 miles per year this equates to 10 -13 years of service before breaking down or requiring expensive repairs.
2. Diesel Fuel. Another reason diesel engines last longer than gas engines is due to the fuel that they burn. Diesel fuel is a type of distillate fuel that is essentially produced from crude oil, which gives diesel engines slower cylinder wear than gasoline engines. This gives diesel fuel lubrication properties that extend the overall lifespan
The Audi 3.0t engine in that car is very well designed and a great performer. It made Ward's 10 best engine's list for 5 years straight (2010-2014) until Audi's diesel scam surfaced (not related) where Ward's pulled ALL Audi motors from their review.X1e0q.
