2006 Infiniti M45 Sport 4dr Sedan (4.5L 8cyl 5A)


Review

Wanted to give a long term persepctive on the M45 (Sport) I have put over trouble free 60k miles on the car. I must say it has surpassed the high expectations I had when I bought it 5 years ago. I had purchased the car after Car & Driver rating it higher than the 5 series. I drove several of the competitors and was sold due to the handling, power, technology, build quality (only Nissan built in Japan in 06) and vale. It price out 15k less than comparable BMW, lexus & Mercedes. The car continues to deliver all the positive traits to this day!


Favorite Features

Handling/ build quality...still as tight as the day I bought it. Strong and smooth V8 that sounds terrific with an Injen intake! Very comfortable highway cruiser for the whole family, the seats are better than my previous Recaros and the other creature comforts are top notch. The suspension, road noise and handling improved greatly with different tires (Hankook V12's!) Reliable, sophisticated vehicle. Definitely the best car i have ever owned!


Suggested Improvements

Fuel economy was advertised as 16/21 and i have consistently got 20 mpg over the life of the car. I am an aggressive driver that put on mostly highway miles. Adaptive cruise control is way too sensitive and the firmware upgrade needs to be done after every battery disconnect.

Review

This newer M45 made a big impact on me after trading in my G35 coupe. The front fascia resembles the Infiniti family tree. The overall styling is modern with a touch of upper level class. The car itself looks great but with the optional aero-kit, it really makes a bold statement. The interior is good but could use better front seat with multi adjustment seat of other cars in the same class. It only offers your basic functions. Good take off from a stand still but runs out of steam after 75mph. Transmission shifts good but could use the 2009 7 speed transmission. Good pricing and good high quality building makes structure solid.


Favorite Features

Style and good lower rpm torque. Easy to use interior controls and very good voice commands. Rear seating is spacious with adults.


Suggested Improvements

Upper rpm hp or torque. After installing a cold air intake and full after market exhaust made a huge improvement by 42hp and 51 lbs of torque by dyno numbers. Front seats could use more adjustments.

2006 Infiniti M45 4dr Sedan (4.5L 8cyl 5A)


Review

06 M45 non-sport journeyman off lease 32k miles. So much fun to drive you just donít want to get out. Powerful and smooth acceleration at all speeds. All controls are easy to operate. Iím 6í4 & fit very well in terms of head and leg room. The M45 was the right combination of power, ride quality and technology goodies for me. The Bose sound system is wonderful. The M45 sport was just too stiff a ride for me. The M35 does not have the same power, only 1 MPG difference anyway. I bought the Infiniti extended warranty (bumper to bumper) till 100k miles or 2014. Infinity also has the best car loaner program. You always get a loaner (g35) no matter how old or out of warranty your infiniti.


Favorite Features

Price. Power & ride quality. Extended warranty and loaner program. This is just a cool powerful luxury sports sedan.


Suggested Improvements

More power (did I hear M50 390 horses)?

Review

Purchased the M45 after owning a BMW 525, then a 2000 740IL. The Tech package of the M is awesome. Love the 3D GPS, voice activated controls, rear backup camera, A/C control seats (could be better), and overall looks. But from the very first oil change, have noticed using oil; not leaking, not smoking, but I have added from 1 to 2 quarts between changes. Also, moonroof leaks in any car wash, have had to have the AC serviced each year. Heated and cooled seats do not compare to the BMW. Ride is noisy, low-profile tires look great, but makes bumpy ride. If battery dies, no way to open the trunk (for jumper cables).


Favorite Features

3D GPS, voice activated controls, sound system, looks, dash lightings, entire tech package, keyless usage, great paint job


Suggested Improvements

Expand 16 gal tank (could reduce size of trunk for bigger gas tank), gas mileage, auto trunk lid open, key access to the trunk for emergencies.

Review

This car is simply amazing. With the luxury and performance combined together, few can match. Infiniti gets it just right. It is packed with luxury options to make it a true luxury car, while the 335hp V8 with firm suspension makes the car a true performer. It is not a sports car for sure, which it should not be, as it is a luxury sedan. This car makes the trip enjoyable no matter drive it fast or slow.


Favorite Features

Pretty much everything.


Suggested Improvements

Maybe fuel economy on the highway with 7 speed - but make sure it is as reliable. Would rather have a reliable 5 instead of a somewhat reliable 7 though.
