2011 Infiniti M56 x 4dr Sedan AWD (5.6L 8cyl 7A)


Review

I have been driving BMW 550i since 2006 (first release of 550i). I cant deny I had a lot of fun and appreciation toward my Beemer. But I did not notice any subtaintial improvement from the model 2006 to 2008, even the HP remained the same between 2006-2008, this year they did man up to 400 HP...but the price also jump to almost 1.5 times. So I took a look at Audi, Lexus, Acura and eventually ended showing up in infiniti showroom. I was not really thrilled about exterior but the performance of the car is outstanding. The comfort seating, smooth driving and the 420 hp did blow me away. The navigation system, rear view camera, and the gear mode changing are excellent...

2011 Infiniti M56 4dr Sedan (5.6L 8cyl 7A)


Review

Had an E550 that i liked a lot-but it was not very sporty. The interior is much nicer than the e550. the performance is about the same. i love the change but have nothing bad to say about the E550. Also like the larger feel of the infinity.I think the E550 is more expensive when you consider option for option.


Best Features

keyless start and beautiful interior, power


Worst Features

trunk should have power assist

2011 Infiniti M56 4dr Sedan (5.6L 8cyl 7A)


Review

I'm happy with just about everything on and in the car except the transmission is jerky and undecided as to what gear it should be in at slow speeds. Between 20 - 40 mph, the gears shift up and down over 1K rpm because the computer can't figure out what gear to be in. The car actually jerks back and forth. Infiniti knows about this and is working on it.


Best Features

nice sound system, maybe a few more features needed in the storing and playing of CD's


Worst Features

Keyless entry, you need to physically push the door handle button, the 'Blind Spot System' has blind spot and lane changing on the same button that can't be reached while you're diving - they should be in the Set Up on the screen.

2011 Infiniti M56 4dr Sedan (5.6L 8cyl 7A)


Review

Have owned many luxury and sports luxury cars. This one is my first Infiniti and the most fun to drive. Excellent power although acceleration is not a smooth as competitors. Excellent ownership experience so far despite some hick-ups.


Best Features

Powerful acceleration. 420 horses. Beautiful interior. Great radio with speakers everywhere.


Worst Features

Lane departure system is annoying. Need to turn it off each time I start her up. Excessive dirt on rear bumper (white car) above dual exhaust pipes that has already required 2 trips to dealer to clean with a special solvent that is clearly an exhaust design flaw and is in need of a fix

2011 Infiniti M56 4dr Sedan (5.6L 8cyl 7A)


Review

Infiniti has gone to great lengths refining many aspects of the M for 2011 but there are still many things that need improvement. While I enjoy my M56 a lot, there are features that worked better on my '08 M45 (such as XM NavTraffic, which is a disaster on the M56 and every other 2010+ Infiniti model). And there are features that are completely backwards, like the armrest button you press OUT to fold the side mirrors IN, and the song selection button you press UP to switch to the next song DOWN on the list. Doors lock automatically at 15mph and you can't do anything about it. And there is so little ability to customize the warning/intervention systems that one is inclined to leave them off!


Best Features

Blind-Spot Warning/Intervention; no more legal challenge from the navigation system every time you turn on your car; gorgeous interior; more-powerful engine with better gas mileage than M45; Forest Air; ventilated front seats; comfy front seats with Deluxe Touring Package; Malbec Black exterior.


Worst Features

The Around-View Monitor found on the FX, EX, and QX is the most egregious omission from the M. (The BMW 550i has it!) There isn't any form of visual/audible distance warning for the front end and four corners, which is ridiculous. Also, add a Valet Mode, and enable Bluetooth Call Waiting/Caller ID.
