2011-14 Audi A4 Quattro VS 2013 Infiniti G37s Sedan

[ClutchMaster0X9]

Hello everyone! New to the forum!
Recently I've been highly interested in buying a second car to build. Currently my daily is a modified 07 Ford Focus with some tasteful bolt ons and tune. Very fun to drive, easy to maintain, easy to build (easy being used very loosely). I've been searching car after car to find my next potential build and daily. Narrowed it down to two great vehicles.

I'm more biased towards the 13' A4 Quattro because I always wanted an Audi since a kid, the history of the company and the engineering that goes into each vehicle. Its amazing. But....., the G37s has the power I want to build off of, they're built like tanks and has one of the best built v6s some would say.

I want reliability, power, performance, looks, and a great platform to build on.
The A4 only concerns me with its maintenance costs. Of course its not as powerful as the G37s but I really want the A4 I just dont want to shell out a lot of $$$ on maintenance rather than upgrades. Also I dont know if I can afford to maintain the car for long term usage sense I plan on owning the car for years to come. What do you guys think? Share your thoughts and opinions...

A4 is already turbo - G37s is not. If you buy a newish B8.5 and get a tune, downpipe and intercooler you would be in the ballpark of the same hp. With a turbo upgrage i.e. K04 or better yet a big turbo than you would be quicker. Quattro is hard to beat as far as awd. Maintenance isnt so bad, just do it yourself as theres diys for most basic maintenance. Audi Interior Is much better imo. I guess it comes down to price, what you want to do with it, is it your only car if you choose to heavily mod, or just somethingquick and reliable.

It's not directly comparable, but I previously had a first generation G35 sedan and it completely turned me off of Infiniti for a good while - talk about maintenance costs and headaches, holy shit. I had to replace cam position sensors every 4-7 months like clockwork. Passenger power seat stopped working, it would only go forward not backwards so anytime someone adjusted it, that became the new permanent position. Eventually no one could sit in it. CD player ate CD's. Center console shift lock broke, ended up needing to carry a small flathead just to shift out of park every day. The ignition eventually stopped turning the car off, I had to carry a plastic bag and cover the intake to starve the engine of air. Occasionally, for unknown reasons, some faint smoke would seep up from behind the gauge cluster. Replaced 4 thermostats. The dash creaked and cracked to no end. The driver side HID ballast went bad and needed to be replaced consistently.

Im sure they've gotten better since then though.

Nicely put and I'm looking at preowned for each one just cause I could care less about new right now. I'm 22. And I can get either car preowned around the same amount, $19,500 - $23,000 with generous mileage. Im looking for a second car to modify to be a great daily but also track ready for weekends. I'll still have my Focus regardless, im keeping it, been in my life for 9 years. I can DIY for maintenance but I'm kinda nervous. Do the B8s have a lot of mechanical issues? At my local meets everybody tells me they have a ton of issues but you cant always believe what people say, especially since they never owned one.

Gesshhh man, its crazy cause a lot of the nissan guys say the cars are built really well at least for the V6. 370z and G coupes and sedan owners say they rarely had issues....... or they could be trying to sell me on the car. Lol . Either way sorry you went through that. What do think about stock platform performance for the B8? A4 Quattro definitely isn't a S4 but would a first time Audi owner enjoy?

Yeah, I'm 110% sure my experience is an outlier to the rest of the pool. I even entertained the idea of a new Q50S when I was shopping for my Audi, but it reminded me so much of the G35 (even being 10 year newer) that I quickly took it off my list. It drove, handled, felt, and sounded just like the G35 and I thought that a 2014 Q50 should not remind me of a 2004 G35, it should be more refined after a decade later. It wasn't, but take my notes with a grain of salt, it's just my personal opinion.

The fit and finish of the Audi is light years ahead of Infiniti, hands down. Performance wise - stock for stock the G37 outperforms easily (though, that can be flipped pretty easily with a tune and an HFC).

As for reliability, if a B8.5 2013+ Quattro is in your budget you will likely have very minimal maintenance costs - they're solid. I've only ever needed regular oil changes and scheduled maintenance (spark plugs, cabin filter, air filter, etc) on mine in the 2.5 years I've owned it.

Our family has both a 2013 A4 and G37x.

Reliability - G37. Mechanically it’s been bullet proof. Most reliable car my family has ever owned period. A4 had some warranty work done, but other than that has been very reliable too. Long term, there is no question the Audi will cost more to maintain.

Performance - Power delivery is completely different. G37 has +100hp, but both cars make similar torque. Difference is the A4 makes its peak torque at 1500rpm while the G37 at 5000rpm. So the A4 feels much quicker in daily driving whereas the G37 must be revved out to feel fast. The G37 is faster if you’re wide open at high RPM, but the rest of the time it actually feels slower. Handling is sort of reversed. The A4 actually handles better at the limit, but the G37 has more direct steering feedback making it feel more connected in casual driving.

Platform for Mods – The G37, being a NA V6 with 330hp, doesn’t have a lot of room for improvement with simple bolt on mods. The A4 on the other hand can be significantly improved with a tune, exhaust, intercooler, etc. An A4 with a few simple mods will walk a G37. Modified turbo motors are just more fun. They provide a lot more useable torque. Makes the car feel very quick and responsive in the mid-range where you do a majority of your driving.

Quality – There’s just no question the A4 is on a different level. From the interior materials, fit & finish, thunk of the doors, etc…the A4 feels like truly premium car while the G37 feels like an upgraded Nissan.

I totally agree with this. I test drove their 2015 model and was totally dissapointed. Although Infinity has a lot more power it does not feel that way. If feels slow and not as powerful. Everyday driving is where it is for me, and Audi totally won due to torque.

So only when you step on it and get in the higher rpm range is when the Infiniti show its power? Definitely need that low end responsiveness

So any model before the B8.5 had a lot of maintenance issues? I read on here that the 2013 and 14 had a issue with the electronic steering? Was there a recall on that? Or just certain cars had it? And buying the B8.5 should I get the Audi Care service too?

So the B8.5 isn't fragile right? Its crazy so many people think Audis are soo fragile and delicate that you cant be aggressive with them lol

I think a lot of that stigma is still hanging around from the older B5's, who's natural habitat was being paraded around on the back of flatbeds.

[Project Quattro]

Regarding the electric power steering issues, as far as I can tell they were pretty uncommon. It was suggested that I add them to the Buyer's Guide, but I don't recall seeing anyone on here actually report that it happened to them. I would echo what was said above... A 2013 or newer car shouldn't bury you with maintenance or issues.

Okay gotcha, what about the burning oil topic as well? Does the 2013+ models have that issue or is that also uncommon as well?

B8.5s, 2013+, seem to be immune from this issue.

Lmao but I still loved my b5 to death. 110k and I only towed her once or twice! Go Audi and never look back!

[subzero05]

toos up really. I've had a G37 and loved it. nice power curve and mechanically sound. I do actually enjoy driving the audi better however and there are a lot of parts for it to build upon.
