The Infiniti M-35 Hybrid: Sometimes a Gas Saver

February 21, 2012


By Roger Witherspoon

 

            I knew it was a hybrid. I just didn’t care.

Saving money in a hybrid is mostly a matter of with fulfillment: you want better mileage, so you drive differently than you normally would. Instead of burning rubber, you take off slowly, allowing the electric motor to accelerate the car at a rate slow enough to allow you to finish your morning cup of tea before reaching the nearest intersection.

On the highway, you avoid the passing lanes and go with the slow flow. If you have to change lanes, you wait till there is an opening rather than hitting the accelerator and jumping into a small, moving slot.  All the while, you are watching a luminous dial by the speedometer giving you a second by second reading of your gasoline miles per gallon – and you really, really like the number to be north of 50. It’s a sensible, safe, self-taught, economic way to drive – but only if you are in the mood to be sensible, safe, and economic.

Which brings this discussion back to a sunny day with a dry, nearly empty highway, and the 2012 Infiniti M-35 hybrid. At the push of a button, the eight-inch, color navigation screen  readily shows you where the power is coming from – the 302-horsepower, V-6 gasoline engine, the 67 horsepower electric motor, or both if you mash the pedal to the floor.  The latter move, of course, defeats the purpose of a gas saving hybrid.

But then, the hybrid combo can be viewed as a gasoline engine enhancer, rather than a gas saver – and the nearly 200 pound-feet of additional torque provided by the electric motor directly to the axels pushes this hybrid, family sedan into the category of a sports car.

So I floored it. The 18-inch rear wheels dug in as the M shot forward, the speedometer hitting 60 in just over five seconds and passing 100 and the quarter mile in just over 13 seconds. And then, since one can’t go too far or fast on the Northeast highways without upsetting the guys with the sirens and guns, it was time to slow down, act responsibly, and enjoy the ride.

One can actually get a speeding ticket while acting responsibly in the M-35 – its electric motor is capable of pushing the car past 60 miles per hour, about twice the norm for most hybrid electric motors. The combined system provides the power of a V-8 engine while sipping gasoline like a more sedate 4-cylinder, Audi A-4. The sedan has an EPA rating of 27 miles per gallon in the city and 32 miles per gallon on the highway – but if you drive for fun the actual mileage is likely to be considerably lower and you’ll just have to grin and pay at the pump.

      There are a number of thoughtful features in the M, beginning with the notion that if you pay $65,000 for a car you want a lot of comfort and amenities in addition to speed. Buyers in this range are looking for more than mere transportation: The car, as an art form, has to have an irresistible, aesthetic appeal. With the M-35, you can start with the sculptured theme of flowing raindrops. The outer shell is wide with a hump over each front wheel, tapering towards the rear as if the car were comprised of a flattened bubble flanked by two stretched raindrops. It is a theme repeated inside, with oak wood grain flowing in gentle curves across the dashboard and around the chrome door handles.

Infiniti’s designers also gave some thought to pedestrians, who might not hear the car coming if it is in electric mode. The biggest danger to pedestrians comes when cars are slowing down to turn, and those who listen but don’t look are particularly threatened by hybrids and plug-in electrics. So the electric motor has a built-in whine which comes on when the car starts, and gets louder as the car drives, cutting off at 15 miles per hour on the assumption that pedestrians aren’t in the middle of fast moving traffic.

The central console is nine inches wide, containing a cup holder designed to securely hold two large cups or water bottles side by side, and a thickly padded arm rest over a deep storage bin. The arm rest is wide enough to be comfortably shared by the driver and passenger, and adds to the spacious feel of the interior.

The wide leather seats are power adjustable, have powered lumbar supports and as expected, the may be heated. The leather-wrapped steering wheel telescopes and tilts, contains fingertip audio, cruise and Bluetooth controls and at the touch of a button is also heated – which is really appreciated at this time of year. The leather padding on the dash and side walls are offset by generous use of wood trim made from Japanese ash.

Like most cars of this era, the M-35 uses an “intelligent” electronic key, which merely has to be inside the vehicle in order for you to start it by pushing the ignition button. But this key is a bit smarter than most. Once you have set your seat, mirrors, climate controls and turned on the audio system to your preferred sounds, the key memorizes it and makes any necessary adjustments as soon as you start the car.

For sound, the M comes with XM satellite radio, as well as a USB port and iPod connections. The Bluetooth, which is easy to set up for cell phones, also serves to provide music from a smartphone or other Bluetooth music system. It has a single disc CD player and surround sound provided by a 16-speaker Bose system. In addition, there is a 9.3 Gigabyte hard drive music box to store 1,000 or so of your favorite jams. The XM satellite system also serves to provide real-time traffic updates for the navigation system, which is both easy to use and see on an 8-inch color pop-up monitor.

The M-35 offers a lot for those interested in a comfortable, fuel efficient, luxury sedan. It also offers a lot for those who are primarily interested in performance sports sedans and consider gas mileage a secondary consideration.

Sometimes, it’s nice to have choices.

Mercedes C-300: The All-Purpose Luxury Car

December 31, 2011

 

By Roger Witherspoon

 

The snow was no problem.

It was only about two inches deep and, at that level, most cars would ignore it. But the temperature kept skipping just above freezing, producing cold rain, and then heading back south, turning the white stuff into a two inch glaze. It was the kind of road conditions made primarily for snow plows, tow trucks, and Jeeps and if I didn’t have to take a low riding, sleek, Mercedes sports sedan out during the middle of this mess I wouldn’t have.

Not that it mattered. With some cars, icy conditions are problematic and the only way to move is by disconnecting the electronic traction control because the continuous, unpredictable, uneven skidding among the tires crashes the wheels’ computer system. That was not a problem here. While the five-spoke, 18-inch aluminum wheels and  all-weather radials looked good on the four-wheel drive Benz, they were also quite functional and treated the ice as just another hard surface.

That was helpful on the Taconic Parkway rolling through the Franklin D. Roosevelt State park behind a fast moving Jeep Cherokee. We entered a slight curve in the highway and the rear of the SUV began to sashay back and forth. The driver, panicking, hit the accelerator in an effort to bull his way through the ice – which was precisely the wrong thing to do. The Jeep did a slow 360 across the three-lane highway and ended up on the shoulder.

            I eased up on the C-300’s accelerator to give the Jeep space to dance across the lanes, and then easily cruised around him and continued on my way. There is a lot to be said for having four-wheel drive, traction control and appropriate tires.

            The new Mercedes Benz C-300 is a four-door sports sedan whose long, sleek, low silhouette is intended to turn heads. But its exterior design, for all its eye-catching details, is always second to its primary function providing safe, sure, extremely comfortable transport in all conditions. In that regard, the Mercedes C-300 is a petty package on a really efficient, versatile, sports sedan that offers a lot for about $48,000.

Under the hood is a relatively small power plant for a sports model, producing just 228 horsepower. But it is mated to a seven speed, automatic transmission which seamlessly gets the most torque out of each gear and effortlessly shifts among them. The quality of the transmission is particularly evident when used in electronic manual mode on an open road. It is not a car for drag racing – the top speed is just 130 miles per hour, and it accelerates from 0 – 60 in just over seven seconds. But except for Saturday night drag racing on certain urban streets, you really don’t use maximum acceleration unless you are already on the road and need to pass something in a hurry or get out of the way. And when it matters, the C-300’s power plant can deliver.

The ability to maneuver on icy terrain is part of a package of road condition safety features Mercedes hopes will steer buyers to its showrooms the same way Volvo cars have traditionally drawn those who view safety and stability as primary features.  In addition to the relatively standard traction and stability controls, Mercedes’ engineers have added capabilities, such as cross wind sensors which actually shift the angle of the car’s chassis to slightly tilt into the wind. The effect of the innovation is particularly noticeable on mountain curves, where you can hear the wind howling down the side of the mountain towards you, only to flow harmlessly over the changed silhouette.

This Mercedes has side radar alerting the driver to the presence of cars on either side when changing lanes – a feature that is becoming common in upscale cars. But Mercedes has changed it from a passive system noting objects in the area, to an active safety system calculating how fast the distance between the cars is closing. The system can do two things: alert the drive to a possible pending collision and, if a crash is imminent, apply safety features such as tightening safety belts, reducing speed, and readying airbags.

            Inside the sedan is what you would expect to find in a luxury car: a powered sunroof and rear window sunscreen; soft, powered, leather seats which are heated in front and can fold in the rear; and a host of electronic gear. The leather-wrapped steering wheel tilts and telescopes, and has fingertip controls for cruise, information, audio, and easy to use Bluetooth. There is a 7-inch pop-up color screen for the navigation and entertainment systems.

For music there is a 6-disc CD player, as well as connections for USB drives, iPods, and MP3 players, as well as a six gigabyte hard drive to carry 1,500 or so of your personal favorites. The music emanates from eight speakers, producing a smooth surround-sound blanket which could lull you to sleep – except there is an alarm which goes off if the car drifts into another lane or onto the shoulder.

Whether one is driving through snowy, seasonal Nor’easters or watching the speedometer hit triple digits while rolling past mountaintop windmills in the Berkshire Mountains in Massachusetts, the C-300 provides quite a ride.
