2007 Nissan
Altima Road Test
It's not often in the automotive world that a sequel to a great
car is actually better than the original. However, the mandate given by
Carlos Ghosn, head of Nissan and Renault, was just that. Make the new Nissan Altima for 2007 better in
every way than the stunning 2002 Altima. Tall order, but the designers and
engineers assigned to this project proved to be up to the task.
When you walk around the car, you can see the similarities to the original design, but the new car
seems cleaner and more flowing. The more I look at it the more the word,
"inspired" comes to mind. This new Altima is simply beautiful from every
angle.
The
interior of the previous model needed some work. Oh, it was roomy and
comfortable, but quality of the materials and the fit and finish were not up to
par with the competition. This was one area that Nissan knew they needed
improvement in.
Well, I can tell you that the interior of the new Altima
certainly is better. New soft-touch surfaces on many interior panels along with
sharper, easier to read "Fine Vision Gauges" give the Altima interior
a more upscale look and feel.
The steering wheel is now adjustable for reach and height with a
single lever action. Front seat cushions have been
lengthened by 15 mm and rear seat legroom has been increased by 3.1 inches.
The fit and finish throughout the interior is first rate and gives the feeling
of a car costing thousands more.
The excellent Nissan-Infiniti GPS navigation system is an
available option on more models now. For 2007, the navigation system also includes Real-Time Nav-Traffic.
Nav-Traffic allows you to receive up-to-the-minute traffic information
superimposed right on the map display. It will also tell you where any traffic
tie-ups are located due to accidents, construction, or just plain too many
cars on the road.
This information is provided by
an XM radio signal, so you will also
need to subscribe to the XM Nav Traffic service which costs around 10 bucks a
month. Nav Traffic information is currently available in many major
metropolitan areas in the US. Check with your Nissan dealer to see if your
area is covered.
If you commute to work by car, this service is worth every
penny. You won't have to keep your radio on a station that has traffic
reports if you would rather listen to music.
If you want to know about the traffic, just look at the map screen. If the
road is green, traffic is moving at the speed limit. If it is yellow,
traffic has slowed down. If it is orange, expect stop and go delays.
Icons on the map screen show you where there are any accidents. Different
icons show road construction areas. No, there are no icons that show where
police radar is hiding. Mr. Ghosn? Are you listening? People
will pay big for that feature.
The system also includes a jack for your ipod as well as Bluetooth so
that you can link it to your Bluetooth compatible phone and make or receive
calls hands-free using the audio speakers and microphone built into the car.
For those who are not familiar with GPS navigation, you will be happy to know
that there are no subscription costs involved. A GPS navigation system
displays a map on the screen and gives you turn-by-turn instructions to help you
reach any destination in the US and much of Canada.
The 2007 Altima is built on an all new "D" platform that has been
engineered to be more rigid with improved crash worthiness. There is a new
front sub frame and revised suspension system that places the front drive axles parallel
to the ground for near zero torque steer. The rear suspension is also improved with increased use of
aluminum for less unsprung weight.
Unsprung what??
Let
me explain what is meant by "unsprung weight". Most of the weight of a
motor vehicle is being supported by the springs at each corner of the car. This is referred to as
sprung weight. The weight that is not supported by the springs, the wheels
and tires, brakes, control arms and axles, rest their weight directly on the road
surface. Because of this, they are always reacting to the uneven road
surface by moving up and down.
When a wheel hits a bump in the road at
speed, it is accelerated up against spring pressure at great speed. If the unsprung weight is
heavy, the wheel is going to want to continue going up because of inertia.
If this is allowed to happen, the tire can leave the ground and you
momentarily lose traction on that wheel. The lighter we can make
the unsprung mass, the less susceptible the tire will be to bouncing over a bump.
This will improve traction, especially when driving on rough patches of roadway,
and it will also improve ride quality.
As
with previous Altima models, two engine choices are available: The 2.5 liter 4 cylinder engine has been improved with
100 newly designed parts (which make up 20% of the engine). These changes
are designed to make the engine smoother and quieter as well as improve both
power and fuel efficiency. The 4 cylinder engine has 175 horsepower and is
rated at 26 miles per gallon in city driving and 34 mpg on the highway.
The superb 3.5 liter V6, found in everything from the Nissan 350Z
sports car to
the Infiniti M35 luxury cruiser, has also been considerably revised, with more power (270
horsepower) and has a wonderfully rich exhaust note. This silky smooth engine is mounted
lower in the frame for improved center of gravity and has 6 mounting points
instead of the previous four. Gas mileage for the V6 with automatic
transmission is rated at 22 mpg, city and 28 mpg, highway (21 city & 29 hwy for
the 6 speed manual)
Both engines now
breath through dual exhausts and are each available with either a 6 speed manual
or the continuously variable automatic unit that has done so well in the Nissan Murano.
.This continuously variable transmission will allow
the Altima to get improved fuel economy and smoother performance. With
this type of automatic, you will never feel any shifting, just a smooth flow of power
from a standing start to highway speeds. If you like the idea of shifting
gears, the transmission selector has a manual mode where you can hold a gear and
shift up and down at will. Since this is a continuously variable automatic, these are
not real gears, they are actually simulated by the computer.
Not sure what I'm talking about? Let me explain how
a continuously variable transmission (CVT) works.
A CVT has no forward gears or complex
clutches and bands. Instead, there are two tapered pulleys with a
steel belt connecting them. These pulleys can change their effective diameter
through a signal from the computer. If the pulley halves are squeezed
together making them narrower, the diameter in effect, increases causing the belt to
move to the outer edge. At the same time, the other pulley would spread
out causing the diameter to decrease. Changes in the two pulleys are
always coordinated to keep the belt taut.
If the smaller pulley is being turned by the engine (the drive
pulley), the steal belt would turn the larger pulley (the driven pulley) more
slowly. If the diameters change, the speed of the driven pulley will also
change. By allowing the computer to control the diameters of the two
pulleys, the transmission ratio will smoothly and gradually change from low
"gear" to high "gear"
This
design eliminates the need for a 4 speed, five speed or even a six speed
transmission, instead allowing for an infinite number of "speeds". The net
effect is better fuel economy (at light throttle, the engine rpm is always at
the optimal point for maximum fuel efficiency), and better performance (the engine can
stay in its sweet spot for maximum horsepower delivery)
The parking brake is activated through two different methods,
depending on which transmission you opt for. If you have the 6 speed
manual, you get a hand brake lever on the center console. This allows you
to hold the parking brake on a hill while your right foot is on the clutch.
With the CVT automatic, the parking brake is engaged using a foot pedal, which
clears space on the console and makes it less cluttered.
I had a chance to sample a V6 Altima 3.5 SE, the sport model of
the bunch. We drove along the highways and winding mountain roads that
snake around the San Francisco Bay Area and came away with the impression that
Nissan achieved every goal they had on their list and then some. This car
has a secure, stable feel at any speeds we were able to achieve. Steering
felt crisp, but not overly sensitive, the ride was firm, but comfortable and
performance from the combination of V6 and CVT automatic was stellar. I
have driven many cars in the $40,000 to $50,000 price range that were not as good
as this one.
I kept trying to induce torque steer with little success.
Backing away from a front-wheel drive car because of torque steer is no
longer a valid excuse. On the twisting mountain roads, I had to keep
reminding myself that this was FWD. Unless I pushed the Altima to its
limits, I simply couldn't tell. Cornering was flat and controlled
without a major impact on ride quality.
At the limit, the tires cried "Uncle", they simply were not up
to the type of driving I was subjecting them to. That is fine for this
type of car, since one person in a hundred would regularly subject this type of
passenger car to the kind of punishment we were dishing out. You can easily replace the
original equipment rubber for performance tires and have it all, but you would
seriously compromise ride quality and quiet. Nissan chose the tires for the
Altima SE correctly and most drivers will be happy with them.
There are 5 Altima models to choose from:. 3 models that come with the 2.5 liter 4 cylinder
engine and 2 with the V6. The 4 cylinder models are the 2.5 base model, the 2.5 S with more standard
equipment and more available options, and the 2.5 SL which is nicely equipped
with leather and other standard features.
The new Altima 3.5 SE is the driver's car of the bunch, but if
you appreciate ride comfort over sports car like handling, you will be happier
with the 3.5 SL.
In early 2007, Nissan will add a Hybrid model to the
mix. It will have the 2.5 liter 4 coupled to a Toyota derived hybrid system
similar to the one in the Camry Hybrid. The Altima Hybrid is expected to
get 41 miles per gallon in city driving and 36 miles per gallon on the highway.
The Hybrid will only be available at first in 8 states. These are the
states that have adapted the more stringent California emissions regulations.
They include: California, New York, Massachusetts, Connecticut, Vermont, Rhode
Island, Maine and New Jersey. We will have additional information on this
car as soon as it is available.
Altima can be optioned well for those who were looking for a
more upscale car, but love the Altima styling. It can be equipped with
luxury options like Intelligent Key
and push-button start, dual-zone automatic air conditioning, GPS navigation with Nav Traffic,
HID xenon headlights, and a Bose sound system with in-dash 6 CD changer and 9
speakers.
The advantage of going with the Altima, aside from the gorgeous
styling, is now you can have your luxury sport sedan and still have enough
change left over for a deluxe European vacation for the family.
