Infiniti Q45 Road Test
Infiniti Q45 Front

Silver, large, and implanted with a powerful 340 horsepower V8, Infiniti's Q45 is a bit of a luxury car bargain at $60,000 (US). But, you get what you pay for, and this "bare bones" Infiniti offered only one thing in abundance and that was acceleration. It just wanted to go quickly. Of course, the downside was a real thirst for premium fuel. We were hard pressed to get 20 mpg and in town and that mark could fall to 16 mpg with ease. In other words, if you want to move 4000 pounds of car in well under seven seconds be prepared to pay at the pump.

Mom's view
I was quite comfortable in this Infiniti. The seats were nice and the ride bordered lived up to its luxury label. Our test vehicle had a lot of miles on it and we are glad to report that after 12,000 plus miles of heavy use the car was still quite solid.

It was readily observed that this car loved to ignore the posted speed limit. It wasn't sneaky fast, such as the
supercharged Jaguar which smothers your senses, but more bludgeonly fast. In other words, you have the hammer and you are well aware of the power. The weak spot was the transmission, which had a hick-up or two, but other than that you pretty much were only limited in how swiftly you wanted to go by the fuel remaining in its 21-gallon tank. Coincidentally, despite this less than ecological friendly gas mileage, Infiniti has placed a little leaf on their small, indash monitor. The leaf turns green if you are not accelerating and is drained of its color the faster you travel. Although it was interesting, this is a large, energetic vehicle and driving is not a computer game. I see no benefit for this attractive nuisance.

Infiniti Q45 Side

I liked the a full-size spare, puddle lights under the outside mirrors, and adjustable rear seat head restraints, but most of all the large number of useful standard features made an impact of my value system. You get plenty of safety equipment such as control dual front airbags, front side airbags, curtain side airbags, front-seat active head restraints, antilock brakes, antiskid system, and a tire-pressure monitor.

The other standard issue items were equally impressive with a five speed automatic transmission, dual zone climate controls, interior air filter, power steering, power tilt/telescoping wood/leather-wrapped steering wheel w/radio controls, cruise control, leather upholstery, heated front bucket seats, 10-way power driver seat with power lumbar, a much appreciated 8-way power passenger seat, wood interior trim, heated power mirrors, power windows, power door locks, remote keyless entry, power sunroof, analog clock, outside-temperature indicator, compass, universal garage-door opener, variable-intermittent wipers, superior xenon headlights, and alloy rims. Of all these features, easily the best were the magnificent headlights. They are extraordinary.

Infiniti Q45 Interior

On the other hand, the difficulty in figuring out the climate controls and confusing audio controls was a problem. With time this would not be a problem, but why did Infiniti make the buttons nearly the same size, label them "audio" and "auto," and place them next to each other? I also felt that the voice-activated feature was easy to use. Just a click on the steering wheel mounted button and you could change a number of functions such as the radio station or temperature setting for the driver's side. The driver's mirror also turned downward when you were backing up, which was an interesting feature.

Dad's view
Infiniti builds notable engines and the 4.5-liter V8 is simply magnificent. It has dual overhead camshafts, 32 titanium valves, and continuous variable valve timing. The result is a car that loves to romp, but it doesn't get up on its toes until 6400 rpm, which makes it essential that the transmission cooperates and kick-down rapidly. It doesn't always do this and so we did shift for ourselves on occasion. We found it difficult to more the lever quickly and soon abandoned the notion and accepted the Infiniti for what it was intended, a cruiser. It as also anti-climatic to find the steering is rather dull and there is enough lean in the corners to take some of the joy of spirited driving away. If you are into such adventures, the Infiniti M45 is a probably a better choice with the same engine and a few hundred pounds less weight to tout. But neither car is a canyon runner. We would definitely look into the handling option when buying the Q45.

Infiniti Q45 Engine

Driving such a dominant sedan demands good brakes. The Infiniti has them thanks to brake assist, and electronic brake force distribution features. This is also important because this is a large vehicle with a 113-inch wheelbase, and it takes up over 16 feet of the fast lane. That is a lot of car to stop and it is not nimble.

We test shop cars on a regular basis to get the feel of why and what people are interested in buying. With the Infiniti Q45 the major draw were its unique electronic features and high horsepower rating. But, most of the buyers were drawn to the more agile and affordable
G35 and the FX series that offers the same V8 engine, but with significantly less power, albeit for $20,000 less. No wonder the FX is selling well. But, the overwhelming experience we had at several Infiniti dealers was in a real customer caring attitude. We have experienced that before, for example when Lexus first started selling cars in 1989, but few others measure up. When people ask me why pay more for an Infiniti than a Nissan I ask them to compare the way they are treated and the differences in warranty coverage. The extra money for an Infiniti is worth it. In fact, my brother just picked up a mint I35 for less than a Toyota LE Camry. He is now riding around in a powerful luxury sedan that uses regular gas. So don't overlook the great Infiniti used cars. We have owned an Infiniti ourselves, and found the treatment and vehicle performance wonderful.

There is plenty of room for two in the back, but three would be tight. If they are all golfers forget it unless they want to share clubs, because the trunk has only about 14 cubic feet. The heated and cooled air got to the rear promptly enough, but seated back there you don't feel you are in a luxury car as much as you do in some of the Infiniti's competitors. There are no little touches such as your own radio controls or fold down mirrors.

Infinit Q45 Close Up

The stereo is average with reception being limited. The driver computer is easy to mange, but quite complex to master for some tasks. With time this should not be a problem. An interesting option is available when you order a Premium edition of the Infiniti. It is a rearview monitor camera that works when the car is placed into reverse. We didn't get to test this option, but we know from experience that road dirt can quickly compromise the view.

In front, the cupholders are good, but if you have a tall drink access to the center console requires some dexterity. I liked the foldout door pockets, but they were easy to scuff. There was good storage for the rear passengers.

In truth, this is just not my type of car. I sort of liked its appearance, and the engine was very cooperative, but the ride wasn't to my liking. However, Infiniti has a cure for that if you have the additional funds. You can order an adjustable suspension and I definitely would unless enjoy a Santa sleigh like ride. The Premium edition is also the most interesting version of the Q45. You get the same performance of the Luxury edition, plus 18-inch wheels, heated and cooled front seats, reclining heated rear seats, a nice intelligent cruise control designed to maintain a set following distance from other cars, and the rear vision camera. Also available are the must have satellite radio and run-flat tires.

Infiniti Q45 Rear

Young working female's view
The transmission is not easy to shift by hand, and when left in automatic mode has a habit of upshifting early and downshifting late. Driving on smooth roads is quite relaxing, but there is a floating feel, although surprisingly, the Q does not hesitate to let you know when the road is rough. Cornering is marred by the soft suspension, but the brakes were very good. I had mixed feelings about this Infiniti. I liked its looks and I liked the seats and it was quiet. But parking it was a problem due to it girth and the premium fuel required to make the engine purr made me wince when I filled it up. I probably am not the demographic group Infiniti was looking for anyway, but it would be nice to spark some interest in my age bracket. Perhaps if we had tested the more upscale Premium edition the bells and whistles would have perked my interest.

Infiniti Q45 Stance

Family conference
Damned by faint praise may be the best way to describe the Q45. It does many things well, but nothing splendidly well. Yes, it is quite capable of getting you to work on time, but for the money it should do more especially considering the competition from Audi, BMW, Mercedes, Cadillac, Lexus, and Jaguar. However, if you can get yourself a good deal, the dealer experience and the superior headlights and acceleration make this a clear winner.

Good points: engine, price, customer service, headlights, seats
Needs improvement: gas mileage, dash controls, handling, cargo area
