I've been bouncing around here for about two years now and been visiting frequently since the rumors started on the G37 (07 G35 at the time). I am an original 03 coupe owner and expect a black on black 08 G37 6MT to arrive next month.
My dealer gave me a test drive and I though I'd share my experience with everyone here.
Got back from test driving G37 Sports Journey at Alta Infiniti. The car was the Amethyst Graphite with black interior. I didn't think I'd like the colour when I saw the sample, but I was actually looks very impressive in person. The purple is not overwhelming and blends between dark grey and purple.
As stated before, the G37 have a more refined, mature feel. The interior is a real upgrade. While some have complained about headroom, the car feel far bigger to me inside and outside. The flow of the car is more apparent in person that in pics. I would say the changes equate to the changes between the 06 to 07 G35 Sedan which IMO, look sportier and more upscale. The sound system is KNOCKING! A big upgrade from my 03. The bolster on the seat is great.
In terms of drive, this is a far better day to day car. I drove a 6MT and the gearing is much improved. I no longer need to feel out the gears. The car is very compliant and rides like a sedan on day to day driving, then turns to a sports car when you turn it on. It's more refined which is good and bad (I'll talk about the bad below) and definitely firmer with a very linear power band. Power always seems to be available. I rarely if ever downshift. You never seem to run out of power in any gear. In fact, my friend was able to get it up to 150KM (Canada remember) in 4th gear with little effort and in no time. In 6th gear, just step on the pedal and it goes. I also stalled once, because I forgot I was driving stick. The car does not feel fast, but pulls very well. What you need to do is keep your eye on the speedometer to get a sense of how fast your going. Like I said, the car is more refined, so while you'll be doing things that may have been more exhilarating in the G35, they will feel common place in the G37. Not until I thought about it, did I realize what the car was doing.
The noise isolation is so much better. We had the windows down, the music blasting and it took us a while to realize we where doing 80Km in a 40KM zone. It then dawned on me how aware I would usually have been of wind noise, yet there we were focusing of the richness and definition of the music without any thought of the windows being fully wound down.
Ok, the front-end of the car seems high. When I brought my wife over later she kept point to the front fascia's grill and how pronounce it is. I had to show her, that the grill existed on the previous model. I think my black car will hide this fact.
In terms of the ride, as I stated above it is more isolated. It's still a very fun car to drive, it's just more of a mature, refined vehicles. If the 335i is more refined that this, then I definitely do not want it. You seen to loose some of the fun factor. The best way I can put it is, driving the G35 you want to weave in and out of traffic, driving the G37, you know you can, but why bother.
I also found that with the firmer chassis and the 19"s tires the ride was harder. Not uncomfortable, but you definitely felt the feedback in the steering. Where I never felt nervous in my G35, I often felt nervous with the G37. I was never quite sure what the car was going to do. This might be just getting use to the feel, but I didn't have to do this with the G35.
All and all, I would say that the G37 has improved upon the G35 in every way. I have no regrets in upgrading. Probable the best thing I did is sit in the passenger seat and let my wild cousin do his thing. This really allow me to take the time and appreciate what this car can do. My cousin was blow away with all the features of the car and couldn't believe that this was just the Sport Journey.
By the way if you're in the Greater Toronto Area and want to check out the G37, I'd recommend heading to Alta Infiniti and asking for Matt. These guys are great to deal with and I've never had to think twice about doing business with them. They treat you like family and are very professional. Even though they knew I was going to buy, they called me within minutes of getting the car and gave me plenty of time to check it out. I'll post pics shortly
Here are the pics! Sorry their not that great!
I've gotten some great information on this forum and love the enthusiasm. I'm glad to be onboard. If some can let me know how to convert these images to thumbnails, I'll update them.
