2007 Infiniti M45 Consumer Reviews

Most fun sedan I have ever owned

2007 Infiniti M45 4dr Sedan (4.5L 8cyl 5A)

Review

Overall, this is a great sedan. The mileage is rated at 17 city and 23 highway and I have been averaging about 19 combined. I live in Minnesota and we had our first major snowfall yesterday. With rear wheel drive and the all season tires it did not perform well so I am having some snow tires put on. That should make a huge difference.

Favorite Features

Rear view camera, navigation system, acceleration, push botton start, interior materials are very high quality.

Suggested Improvements

The voice activation has difficulty understanding certain words, particularly words that start with "E", but at least it can always be typed in if you are at a stop. Also, maybe add a 6 speed transmission to improve mileage.

M45 Review

Written by: Dan on 09/28/2007

2007 Infiniti M45 Sport 4dr Sedan (4.5L 8cyl 5A)

Review

While this car is complete with everything, the only thing that is in need of improvement is the Sport Rims. The car runs fantastic with every possible feature, DVD, Bluetooth, navigation with voice recognition, etc. However, the roads here in New England make sense for stronger sport rims as they are built too soft and have twice caused major cracking to the wheels which had to be replaced. While this is a not necessarily a flaw, normal driving conditions in New England include potholes, and hindsight is 20/20 and I would have chosen different more durable rims, although the sport rims give a better appearance.

Favorite Features

Rear camera, Bluetooth, smoothness and power, voice navigation.

Suggested Improvements

Forged wheels to be built with more durability, and possibly MPG improvements (lucky if i get 15 MPG).

Review

Being my first sedan since my 1989 Ford SHO, and many Suburban and pickups in between, I spent 1 year researching and dreaming of what I wanted in a sports sedan. The Infiniti M45 Sport has exceeded all my expectations. My only complaints would be the poor fuel mileage (what did I expect in a 335 hp hot rod?), perceived need for a six-speed transmission, and the non-effective high-beam headlights. But these complaints would not deter me from buying this car all over again. I probably should have sprung for the Bose 5.1 surround-sound system, but the regular Bose system is certainly no slouch. Fresh off a mountain romp through the twisties, the smile on my face could very well be permanent!

Favorite Features

Deceivingly smooth and powerful engine. Solid and quiet chassis. Extremely supportive seats. All kinds of techno-features. Way cool nav system. Roomy front and respectful rear seat room. Great handling. More than ample trunk space.

Suggested Improvements

6 speed transmission. "Real" high-beams (HID?). Better fuel mileage (see first suggestion). HID/better fog lamps. Separate control/more powerful sub-woofer.

Best Car in Class

2007 Infiniti M45 Sport 4dr Sedan (4.5L 8cyl 5A)

Review

I bought the M45 sport 2 months ago and can't be happier with the choice I made. This car handles and drives better than the competing 5 series models I drove and leaves most luxury sedans in the dust. It wasn't the value that drove me to buy this car (it is way cheaper than the beamer) but the overall package. Even the much more expensive BMW 550 doesn't deliver the luxury this car delivers, and I prefer the interior of this car. The back seat passengers have more leg-room and can actually adjust their seats. This is the first time my two kids have stopped fighting over the front seat. The younger one actually prefers the back. Overall, could't be happier. Love, love the car.

Favorite Features

Voice control, bluetooth, air-cooled front seats, active rear suspension, the big trunk, the Nav system.

Suggested Improvements

Fuel econ could be better but with the v8 the econ is understandable.

Review

Car is a great mix of luxury and power and sports car all in one. Very comfortable seats, very smooth power. Car really does well in the 40-80 acceleration. 4000 miles and only an oil change. Car handles very well, better than my BMW 530i.

Favorite Features

Engine, seat comfort, real wood interior, active cruise control, stereo system.

Suggested Improvements

Needs 6 speed transmission to get rpms down at freeway speeds - would help gas mileage.

Outstanding Sport Sedan-Best for the US!

Written by: Dave on 07/09/2007

Vehicle

2007 Infiniti M45 Sport 4dr Sedan (4.5L 8cyl 5A)

Review

I test drove BMW 335i and xi, 328xi, and 535i and xi, and although these cars were more aggressive driver's cars than the M45 sport sedan, I purchased the Infiniti. Major deciding points: M45 was priced similarly to the 335xi, but had more power, better features, and much better interior than any of the BMWs. If I were driving in Europe, I would buy the BMW, but in the US, the M45 Sport is a better package and it is cheaper!! By the way, the 328xi and 530xi do not even compete with the M35, let alone the M45. If you are seriously considering any version of the 2007 328 or 2008 530, do yourself a favor and compare it to the M35/45. Infiniti clearly beats these cars!

Favorite Features

4.5 V8. Active steering. Awesome braking system. Navigation system. Adaptive Cruise (didn't think I wanted this, but now I always use it!!). DVD-Audio 5.1 audio system.

Suggested Improvements

Make the back end look more like the G35 sedan. Moisture sensing wipers (not just speed sensing). Parktronic system that audibly tells you when you are close to another vehicle (like Lexus).

Problem with headlights

Review

Everything that you have read about this car is true (it's great), it's hard to believe anyone being disappointed with the M45 Sport. However if you drive this car on the highway at night, you need to know that the design of the headlights is faulty. The high beams are focused so high that they do not illuminate the road in front of the car at all. There is a single adjust for both high and low beam lights so if you take your car to the dealer they will misalign the low beam focus if you complain of the faulty high beams. I drive 70 miles at night on a desert highway to work daily, if you drive your M45 in town this will not be an issue.

Favorite Features

Everything except the headlights.

Suggested Improvements

Fix headlight problem.

Review

I test drove Volvo, Saturn, BMW, Mercedes, Audi and Lexus. None of these other cars are so much fun to drive with such great technology features as the Infiniti. My M45 is fast, easy to drive, comfortable with more leg and head space than Audi, BMW or Mercedes has. What a smooth ride.

Favorite Features

Navigation, Bluetooth, DVD, keyless entry and start, rear camera, adaptive cruise control. Horsepower - SPEED!

Suggested Improvements

Privacy glass windows. Better gas mileage/fuel economy. 20" stock wheels instead of 19".

Review

I've driven BMWs 12 out of the last 20 years. Went to look and prices were out of site. Drove 530, E350/550, GS 450h, Audi A6 then the M45. Drove out loaded advanced tech package, spoiler and rosewood. Car is a dream. Has every luxury item that the Germans nickle and dime you with. Very smooth but powerful acceleration. Quiet comfy interior, great stereo and nav, ac seats are great in florida.

Favorite Features

Stereo, V8 smooth power, handling, comfort, looks, quiet, intelligent cruise control really works, bluetooth phone integration.

Suggested Improvements

Needs a 6 speed AT. 3000 rpm at 80 kills hwy mileage. Need an iPod dock.
