Infiniti M56 - Performance. Luxury. Technology.

Infiniti, the upscale division of Nissan, has presented various interpretations of upscale transportation throughout its two decades of existence. The M sedan is today's halo car, with a pleasing blend of performance, luxury and technology. Style and craftsmanship are the mortar between those three bricks.

Just listing the amazing array of features on this midsize BMW/Mercedes/Audi/Lexus competitor would take up more room than I have, so we'll have to look at some representative examples.

Performance is a great place to start. There are two available engines--the 3.7-liter, a 330-horsepower V6 found in the M37 and the mighty 5.6-liter V8, with 420 horsepower and 417 lb.-ft. of torque, that sits beneath the curvaceous hood of the M56. Both engines come mated to a seven-speed automatic. The car comes standard with traditional rear-wheel-drive but you can request the Intelligent All-Wheel-Drive system if you are concerned about traction.

My 2013 M56 was rated at 16 City, 24 Highway, with an average of 19 mpg by the EPA. I accumulated 17.1 mpg--not bad, but premium fuel was running nearly $5.00 a gallon during my test. The 2012 model earned a 6 for Air Pollution and 3 for Greenhouse Gas from the EPA. Big engines have trouble getting a good Greenhouse Gas score, but you can carefully control an engine of any size for low emissions.

Luxury is both a look and a feel. What other motorists see is a bold, curvilinear design that has borrowed something from classic British Jaguars and Bentleys but is comfortably informal too. It's almost prettier than you expect, and it's comforting to look out the windshield at the sensuously proportioned hood. My tester was a Platinum Graphite M56--a formal gray that fits for a car of this caliber.

Luxury is best represented inside, with sublime leather seating, Japanese Ash trim and the long list of amenities that are expected at this price point and market segment. Yes, there's dual-zone climate control, but this car has something even better--Forest Air. As part of the Sport Package (more on this later), it removes odors and then distributes the breeze in an irregular, outdoorsy way. Oddly, when it's  varied like this you are actually more aware of it.

Technology may be the most important ingredient in this super car. A rear-view monitor is nothing that special today, but how about a rear sonar system that detects objects? You have access to the Zagat restaurant guide through the Hard Drive Navigation System, along with traffic and weather information. Rain sensing windshield wipers are no longer a new idea but they fit right in here, along with automatic on-off High Intensity Discharge headlamps.

If you really want technology, though, you have to order the $3,050 Technology package. Here you get a blind spot warning system that tells you, with lights, when someone's next to you where you can't see them in your mirrors. The next step is Blind Spot Intervention, where the rear brakes automatically kick in to guide you away if you try to turn into an occupied lane.

If no-one's there but you need to stay in your lane, the Lane Departure Warning and Lane Departure Prevention systems are there to protect you. Active Trace Control fine tunes engine torque and four wheel braking to keep you poised on curving roads. Forward Collision Warning is part of the braking package that lets you know with flashing lights if you're coming up too quickly on someone in moving traffic. My least favorite part of the Technology Package was the Eco Pedal, which pushes back at you if you drive too vigorously. I'm glad to save gas and the environment, but that's too much nannying.

Further enhancing my tester was the Sport Package ($5,650) that introduced stunning 20-inch wheels to go with lots of "sport" features, such as the Sport front fascia (dark instead of chrome), Sport brakes with four pistons in the front disc and two in the rear. How about Sport seats in front? A Sport-tuned suspension? Four wheel active steering sounds pretty exotic--and Nissan/Infiniti has experimented with it for a while. It just enhances the feeling of agility of this two-ton ride.

Craftsmanship? The pieces fit together perfectly, the materials are top-level and there is such a wealth of things to look at and touch. It's hard to think of anything that could be missing here. The side panels are made of aluminum to save weight, but are hand-inspected to be perfect. You won't get that on a Nissan Sentra.

You'll pay for the privilege of driving an M56. It starts at $61,100, and when you add in the $895 shipping charge you're touching $62K. With the Technology and Sport packages, the bottom line for my car was $70,195.

However, driving a car like this puts you in a different frame of mind. Everything is so lovely, so comfortable and so silent (they even have Active Noise Control, which counteracts engine, road and wind noise). You feel more relaxed in stop-and-go commuting. It feels good to move your eyes and hands over the swirling, exuberant trim and pieces inside. I often found myself feeling the armrest, the steering wheel, the dash, the console.

It's been a long haul for Infiniti--they haven't been the sales star that Lexus has been--but they definitely have found their way today and offer a beautiful alternative to the other upscale four-wheeled choices.

Audi A7 Carries it Off

The new Audi A7, slotted between the midsize A6 and fullsize A8, creates its own identity there. Besides its unique fastback styling, it offers a convenient and spacious liftback--something that some American buyers may find perplexing. Aren't hatchbacks just for cheap econoboxes? Well, no.

The A7 offers all the upscale design and equipment you expect in this segment--you do get your $68,000 worth! The design flows smoothly from front to rear outside and from door to door across the dash inside. The usual high-quality materials and fit-and-finish make the driving environment a joy to occupy.

Audi has smoothed out some of the fussiness on the dash now--the gauges no longer look like teardrops. The lines flow into delicate points on the doors. The doors have their own subtle illumination. The display screen for audio, navigation and car information slips delicately out of the upper dash when you start the car. You can send it back in if you don't want to look at it but it's unobtrusive.

My Moonlight Blue Metallic test car had the Prestige package, which added upsized wheels, navigation, front and rear parking sensors, climate control, BOSE surround sound and lots more. Then, my car had the wheels upsized to 20 inchers! Whew.

The 3.0-liter 310-horsepower supercharged engine sends the car rocketing towards your destination with an EPA average of 22 mpg. I averaged 19.3.

Always a treat, great for carrying big loads, and now, already on its way to the next journalist.

Infiniti M Hybrid - Save Gas in Style

I just stepped out of a week with one of the most luxurious hybrids I've ever driven. Yes, I did spend time with the Lexus LS 600h L a couple of years ago ($112,000) but this new Infiniti M Hybrid coddles while it sips the fuel. An EPA rating of 27 City, 32 Highway (I averaged 25.8 miles per gallon) is excellent--for a 4,200-pound luxury sedan.

The standard M35 without the hybrid is rated at 18 City, 26 Highway, so there's a significant difference in economy. The price is about $6,000 more for the M Hybrid, so it could take quite a while to make up the difference on cost alone.

The M Hybrid uses a powerful 3.5-liter V6 plus an electric motor to generate 360 horsepower (a lot) and 457 lb.-ft. of torque (huge), all through a 7-speed automatic. So, you can at one hand be rolling slowly through a parking lot or in commute traffic using no fuel at all--electric motor only--or be accelerating onto the freeway like a rocket with the engine.

There are simple, understandable graphic displays to understand where the power is coming from and when the battery is being used or charged, so you can monitor your consumption and behavior.

Being the Infiniti flagship, the car is loaded with comforts, starting with the leather-wrapped seats and continuing with silvered Japanese Ash trim (see photo). The design of the car is soft and voluptuous, from the sweep of trim across the doors and twin-cupped "bustier" over the gauges to the Jaguaresque curve of the fenders--visible through the windshield as you drive.

At $67,565, my fully loaded car was much more expensive than anything I'm every likely to buy--you could get two 50-mile-per gallon Prii for that. If you hold off on the extra fancy options you can get it down to $53,700 (base price). But then you'd miss out on the Bose 10-speaker premium audio system and the gorgeous wood.

Now that I'm back in a "normal" Nissan Rogue I remember the way the Infiniti transported me. Now, if it could get 40 mpg...

Acura RL - Honda Goodness--Multiplied

What to make of the Acura RL? A modern descendant of the original Acura Legend, it takes all the goodness of Honda cars--sturdy, reliable, efficient--and stretches them out to luxury proportions and is loaded with every feature you'd ever want.

The pluses are many--from the handsome, tasteful styling (although it is looking a little dated now) to the gorgeous sweep of wood across the dash. The road feel is taut, the steering is communicative and the car drives smaller than it actually is.

Where it loses steam is against the Lexus LS models, which offer V8's (even though you don't really need one) and are just a tweak bigger. The Acura's 3.7-liter V6 offers an even 300 horsepower and an average of 20 mpg (although I got 18.7 in my testing). No problem with that.

Somehow, even though the Acura Legend came first, Toyota has gotten folks to equate Lexus with "top drawer" while the Acura is "very nice." I personally prefer the Acura, but then again, if I were buying an Acura I'd more likely want the TSX wagon or even the TSX sedan with the manual six speed. And I'd probably take a long look at Audis and BMWs too while I was shopping.

But for a luxury car that's big not not too big and luxurious without being ostentatious, it's hard to beat the RL. It's not as popular as some, but you can think of it as a well-kept secret.
