S5 cab vs MB E550
This thread is old but still wanted to reply to the thread as lot of people search for the same question looking for some insight( I was one of them) and now I would like to share my experience.
I am a 30 yr old- love good cars(who doesn't?? right...)
I had a '08 BMW 335i convertible- absolutely loved the car.
When time came to change- I looked into 2 convertible options(performance being top priority)-2013 Audi S5 and 2013 E550.
I got biased by online reviews and wasn't considering E550 in beginning- went straight to Audi dealership. Tried the S5. My impression- interiors:good, looks:good ( not as pretty as BMW) and most importantly the drive/performance:good. The way I put it- it came pretty close to 335i. But for a $70+K car, I was expecting better.
And then I thought, let me try E550. Looks- better than audi(I still think BMW is the prettiest- I may be biased though). Interiors: better than audi.
Performance: On regular/Eco mode- it sounds powerful and controlled, but you switch to Sports mode and it's a beast.For such a heavy car, I was surprised it felt lot different and faster than the 335.
Handling: none of the cars come even close to BMW.
Also, one of the things what I like in my cars is at what RPM does the torque kicks in- it makes all the difference in driving. For eg. if u try a 420 HP Camaro SS with a 0-60 time better than 335i(300HP), the torque kicks in @ more than 3200 RPM(I do not know the exact no.).What does that mean- if you drive on a dragstrip- it might be fun, but on a day to day driving, a lower RPM torque of BMW( @ 1800RPM) is much more fun !!
S5's torque kicks in @ 2800 RPM whereas E550 kicks in @ 1600RPM.
So as soon as you press on the accelerator, you feel the 'kick'. That was a huge factor for me to choose the benz over audi.
In conclusion, E550 cab is way better option than S5 if performance is high on your priority.Looks are subjective though !
