The Infiniti M37 mid-size luxury sedan is stylish, very nicely equipped and features more technology than NASA had available when it put Neil Armstrong on the moon.

But sometimes, you can go a little overboard with the technology.

After spending a week behind the wheel, there are a lot of things I really like about the M37.

It is one of the most nicely appointed luxury cars on the market.

It is extremely stylish, has a comfortable cabin with abundant room for five passengers and the materials and craftsmanship are absolutely first class.

Infiniti bills the M37 as a mid-size performance luxury sedan.

Thatís where I take exception.

While an extremely nice vehicle ó and Iíll agree it is an extremely nice luxury vehicle ó I couldnít come close to calling the M37 a performance sedan.

Its performance characteristics arenít bad, but certainly not what I would consider performance level.

As I mentioned before, the M37 is loaded with technology, one feature being Infinitiís Drive Mode Selector that allows the driver to select one of four modes to control throttle and transmission mapping to optimize vehicle performance.

In the Eco mode, I found fuel economy was improved, but performance was what I would expect from a car costing tens of thousands of dollars less.

In the Sport mode, performance was greatly enhanced ó but still not to the level of what I would classify as a performance car, although its fuel economy numbers plummeted to what you would expect from a high-end sports cars.

Which is surprising insomuch as the M37 is powered by a 330 horsepower 3.7-liter V-6 engine and mated to a seven-speed automatic transmission with adaptive shift control.

When you factor in the price (the test vehicle, when equipped with optional packages and features totaled $62,095), I expected better performance and fuel economy.

Available in rear- or all-wheel drive configurations, the Infiniti M Series is available in five models.

In addition to the M37 and M37 AWD, consumers also have the choice of the M56 and M56 AWD powered by a 420-horsepower 5.6-liter V-8 engine, also mated to a seven-speed automatic transmission with adaptive shift control.

An M35h hybrid model is also available.

I would need all the available space in todayís paper to list all of the technological features on the M37. A very short list includes active noise control; blind spot intervention (which provides selective braking if the vehicle approaches an adjacent line while another vehicle is detected in the blind spot area); Forest Air (which helps reduce the intrusion of unpleasant odors into the cabin); Eco Pedal (which provides driver feedback to encourage eco-driving behavior); and enhanced intelligent key (that remembers last used settings for each key).

There is a lot to like about the M37 and a lot of its technology is spot on. Some of the technology, however, should have been left on the shelf.
