Hi all, I'm doing some research for my mom. She has a BMW 545i and is considering going to an 06-08 A6. Anyway, I'm just curious of common problems. Also I know with BMW that their 6 cylinder engines are generally worse on fuel economy than their 8 cylinder engines. As for the Audi which engine would you recommend aiming for? Remember she doesn't care for speed, just cruising. However, I would prefer the engine that is the least problematic and best in all around economy. All advice would be appreciated.

Thanks.

 

Most of the time, the V6 is less problematic, just because there is less components to brake and better in all around economy. High performance engine usually have higher maintenance. If you buy a 06 A6, make sure it has all the MMI software updated.

 

Not to knock BMW as I am a fan of both makes, the A6 is so much nicer inside and out. The BMW has a performance advantage due to RWD setup IMO. However, most of us don't drive these cars at 10/10ths. I am jealous of your mom I would go with the V6 with quattro if it were me spending my money. If I were spending my Mom's money, I would only be satisfied with an all new S6. And if it was your Mom's money, I would only want an R8 black with carbon Fiber blades.

I drove a brand new A6 3.2 ages ago when I was browsing and it was quick enough for me. I really liked the interior a lot better than the BMW and I thought the exterior was much better styled than the Bangle designed E60. I'm a huge BMW fan but I honestly prefer the older ones over the newer ones. She used to have an awd E46 and it was great, she actually liked it better than her 5 series and it didn't get stuck in the snow all the time. Lately I've been really into Audis especially since I'm really into VWs. If it were up to me, I'd choose the S5 or an RS4 but this needs to be practical. When I drove the A6 last year I was really impressed with the smoother ride than the 5 and it didn't have the stupid I Drive system. Plus I found it had more space and all around it was more comfortable.

Thanks, that link was useful.
