Powerful, great handling, luxurious without being soft. I loved it.
What's the difference between 2006 and 2009? In a word, more.
Certainly more power. 280 horses back then have been bumped to 328 now...nearly 50 more.
More gears. The G35 I drove had a six-speed manual. The G37 I handed back a couple of weeks ago had a seven-speed automatic...which bumps EPA estimated fuel economy up to 18 city/25 highway.
More features...including stuff Infiniti was probably just beginning to dream about in early '06...like the Infiniti Studio on Wheels premium audio system by Bose with 24-bit Burr Brown DAC and Driver's Audio Stage with 10 speakers.
That's how they list it on the window sticker. It's part of the Premium Package. All I know is it sounded fabulous. And it includes a 9.3 gigabyte Music Box hard drive so all your CDs can come with you and stay in your house at the same time.
Truth be told, the Infiniti stayed just this side of triggering my "too much tech" alarm...and I have a suspicion that I'd like the $35,750 base G37 AWD (or the $33,250 2-wheel drive) sedan just as much, if not more than I did the $43,015 fully loaded one. But this one is a solid contender in the sport sedan wars...and even if it never becomes the BMW 3-series killer some are hoping for, it will be fun and rewarding to drive it as it tries.
