Overview & Reviews

Following last year's redesign, the Infiniti M45 gets only minor tweaks for 2007. A 10-way power-adjustable passenger seat has been added to the standard features list, along with a compass and a HomeLink remote transmitter. The car's Technology and Journey packages have been revised, and a new Advanced Package has been added. New SAE engine rating procedures have also resulted in lower power figures for the V8, but actual performance is unaffected.

• Explosive power from a smooth V8, roomy cabin, sharp steering, responsive handling, long list of luxury features.

• Some mediocre interior trim, center stack controls can be a challenge to decipher.

  Most fun sedan I have ever owned - 2007 Infiniti M45
  By Jim Cahill - August 7 - 9:36 pm

  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.

  Best car Ive ever owned - 2007 Infiniti M45
  By mike8231985 - July 9 - 5:08 pm

  I had a Mercedes E-class prior to this and was ready for something more sporty. Im in my 20s, and I think the E-Class is geared towards older people who just want comfort. The M45 is for people who like to drive hard and get thrills from speed and performance. I never thought a sedan would be as much fun/more fun as my BMW 330ci. Reliability is amazing and part of the reason I decided against buying another German car. The Infiniti fits my personality a lot better than the stuffy E-class.

  Outstanding Sport Sedan-Best for the US! - 2007 Infiniti M45
  By Dave - June 10 - 7:43 am

  I test drove BMW 335i and xi, 328xi, and 535i and xi, and although these cars were more aggressive drivers 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!

  M35 - Great Car for Non-Soccer Phase - 2007 Infiniti M45
  By fagnaml - April 29 - 9:06 am

  We purchased an M35 for our new "non-soccer parents" phase of our life (were in our late 40s). After ~6 weeks of driving we are extremely pleased with the comfort and performance (not surprising considering our last vehicle was a Toyota Sienna minivan). The disappointment is the mileage is at the low end of its rating (were getting ~20 mpg when gas is >$3/gallon!). We test drove the Lexus GS 350, Mercedes E350 and Acura RL. The M has the comfort and peformance we wanted.

  My M45 - 2007 Infiniti M45
  By Matt Johnson - February 1 - 7:40 am

  Only negative with sport model is that you will DEFINITELY need snow tires for any kind of winter driving.
