In these days when carjackings and home invasions are very much in the news, perhaps Infiniti’s M sedans are the perfect cars for those who are truly well off.

Although handsome, they’re cars that don’t advertise your wealth.

Much as doctors in decades past drove Buicks instead of Cadillacs, Infiniti’s flagship sedans aren’t as blatant a statement of wealth as some of the high-end vehicles from Mercedes-Benz, Lexus and BMW.

They don’t scream, “Look at me, I’ve made it!”

The M cars come in two versions: the M35, powered by a potent 3.5-litre V6, can even be ordered with all-wheel drive; the M45 packs a bigger punch, with a 4.5-litre V8 under the hood capable of rocketing it from 0-100 km/h in less than 6.0 seconds. Harnessing the V8’s 325 horses is a smooth five-speed automatic with manual shift mode.

Our test car was the M45 Sport and there were no options included in its $73,400 price. Other than the M35’s available all-wheel drive, I can’t think of anything this car could have, but doesn’t.

Standard equipment includes power everything and many functions that are fully automatic including climate control, headlamps and windshield wipers. A transmitter in the fob means no key is needed to either open the doors or start the ignition.

There’s even four-wheel steering to go with a sport-tuned suspension. Although handling is not as crisp as you’d find in a smaller sporting sedan, few four-door cars can match it for flat-out acceleration. Stab the gas pedal at any speed and you’re rewarded with a neck-snapping burst of 91-octane fuelled energy.

The M45 has been called a high-tech powerhouse, which is true. And while I love the power, I can live without some of the electronic gadgetry that overloads the car and overwhelms your senses.

Take the Lane Departure Warning system (LDW). At speeds above 72 km/h it beeps if a wheel touches a painted line on the road. While the LDW default mode is “on,” mercifully it can be turned off via a switch to the left of the steering wheel.

Likewise, the laser cruise control can be turned off by a button on the steering wheel. This system helps maintain a set distance between you and the vehicle in front. While fun to play with for a while, I find the operation of all such systems to be herky-jerky and an excuse not to pay enough attention to your driving.

One feature I did like was the heated and cooled power driver’s seat that slides back, while the wheel tilts up, to allow for easy exits.

When the car is turned on, the seat and wheel automatically remember where they had been and return to one of two preferred positions.

I also like the big screen that’s part of the DVD-based navigation system — not for the nav, which I seldom use, but for the rearview camera. When the transmission is in reverse, the left outside mirror tilts down, the camera turns on and anything in your path as you back up is clearly displayed so you don’t crunch it with those big 19-in. tires.

How much technology is too much? Well, by my count there are 107 buttons, dials, knobs and switches for the driver and front passenger to worry about. Set in the centre of all these complicated controls is an anachronistic analogue clock.

Most of the useable space in the bin under the centre armrest is taken up by a DVD player so those riding in back can watch movies or whatever. These days, I guess, anything’s preferable to talking to your fellow passengers or — horrors — looking out the window at the passing scenery.

For a luxury vehicle, the M45 does not have the quietest of cabins. Although you can hardly hear the V8, even under hard acceleration, there’s lots of road noise transmitted by the low-profile Bridgestone Potenzas. And those tires contribute to a somewhat choppy ride.

The individual front seats are wonderful, and the 308 watt, 14-speaker Bose “surround sound” audio system is a treat for the ears.

But I find the non-reclining rear seat a little too hard and too upright. Although it can seat three abreast it’s better for two. A centre armrest folds down, then flips open to reveal cupholders and a storage bin. A lockable pass-through is perfect for skis and the like.

The M45 comes with all the latest passive safety devices – dual stage front airbags, side airbags for the front seats, side curtain airbags for both rows, pre-crash seatbelts, ABS and traction control, xenon headlamps with adaptive front lighting that turns with the front wheels and a tire pressure monitoring system.

Although this body style has been around since 2005, there currently is no crash test data available for the 2007 M45.

Given its rather subdued styling and explosive power, this may be the ultimate stealth car.
