This is a good day to be in Detroit, especially if you like to go topless.

Porsche unveiled its 2012 911 Carrera Cabriolet today at the Detroit Auto Show, demonstrating its ongoing commitment to creating some of the sleekest, sportiest cars on the road today. Sharing the same updates given to the Carrera and the Carrera S for the new year, this beauty looks fantastic with the top down – as if it were made for the open road on a sunny day. (Which, technically, I guess it was!) The top offers smooth, superbly easy retraction with a touch of a button below the gear selector, but it can also be dropped through the use of the remote key fob. It’s a beauty to behold, but as we all know – even with global warming, that top has to come back up at some point.

And that’s where the Cabriolet truly distinguishes itself. While most convertibles lose their sleekness once the cloth top returns, the Carrera Cabriolet is designed to incorporate the car’s innate sleekness into the design of the convertible top. Gone is the boxy, bulky look that makes us keep those convertibles hidden in cooler months; the sleek new design integrates the look of a hard-top into the easy grace of a lightweight fabric top. In fact, the Cabriolet’s soft-top arch is so well designed that it looks almost as good with the top up as with the top down.

Almost.

Not that anyone was complaining about the luxury of its current and/or previous models, but now Bentley has announced plans for a new and improved car.

The British automaker has announced that, beginning in 2009, the Flying Spur lineup will be joined by its most powerful four-door to date – the Bentley Continental Flying Spur Speed. Combining the cabin comforts of the Flying Spur with the driving performance of the highly acclaimed Contintental GT Speed, this latest addition is a 12-cylinder powerhouse with 600 horsepower that will top out at around 200 miles an hour, besting the Flying Spur’s top number of 195. It will also outperform the standard Spur in the 0-60 showdown, hitting the mark in 4.5 seconds, which shaves .4 seconds off the standard Flying Spur’s 0-60 performance. (Good to know if you’re in a hurry.)

Bentley has lowered the ride height, which will help the car hit its full velocity potential on the open road, and the Speed also boasts a reworked chassis that provides tauter handling and better steering response. With so many racing elements incorporated, designers also gave the car improved agility and body control … and then added thicker anti-roll bars to both the front and back of the car. Not that you’ll need them, of course – but it’s good to know they’re there.

As expected, this car isn’t designed just for superior performance, but for ultimate style and elegance as well. It has the familiar Bentley curves and styling cues, but subtle design shifts make the Flying Spur Speed stand out on the road. The dark-tinted radiator and air intake grilles are designed to emphasize the performance offered by this beauty, and it also sports wide exhaust pipes and unique multi-spoke alloy wheels – which are available either in bright silver or darkened tungsten. Bentley has also supersized the 19-inch tires offered on the Spur to 20-inch Pirelli P-Zeroes.

Like the rest of the car, the Speed’s interior also shows a darker side of Bentley, but it works exceptionally well. With expected but well-executed touches such as the gear lever in knurled chrome and hide, it is as beautiful as anything Bentley has ever put on the road. Carrying out its dark side, even the engine cover is black.

Around town, you’ll be getting about 10 miles to the gallon, although on the highway you can expect to squeeze out around 17 mpg.

Bentley’s official word on the Flying Spur Speed, according to Dr. Ulrich Eichhorn from their Board of Engineering, is that it “advances its Bentley performance credentials while delivering outstanding refinement and comfort through our unique application of advanced technology and traditional craftsmanship.”

Translation? This car has the performance power to blow other cars off the road…and the stylng elegance to knock your socks off in the process.

OK, the answer to that question may seem obvious, but you might be surprised.

According to a recent poll, called the Challenge X Survey, about 88 percent of women said they would be more likely to stop and strike up a conversation with guys who are driving the latest fuel-efficient car as opposed to someone cruising around in a hot new sports car. What’s more, about 80 percent of car buyers here in the U.S. say they would rather spend quality time at a party talking to someone in a fuel-efficient auto rather than an exotic sports model.

This kind of information could cause quite a stir among males planning a mid-life crisis – in the past, they’ve been able to buy a Corvette (or some other life-affirming symbol of their manly power) and call it good. But in light of this new information, what’s a guy to do?

Does this mean that they’ll be trading their Hummers for Hondas? They just might, once they discover that more and more women are turning their attention toward cars that are green instead of admiring those fast, mean machines. What’s more, most respondents in the 18-to-43-year-old category said they consider it a fashion faux pas to buy a car that’s not environmentally friendly.

This, of course, poses questions for those tooling around in the kinds of cars that would only be green if you painted them. What does it mean for their future? That remains to be seen.

Until automakers start producing hybrid and electric vehicles that are as sleek and sporty as their gas-guzzling counterparts, auto enthusiasts are in a challenging position. Yes, I want to save the polar bears … but I’m also infatuated with the Bentley Continental. Fortunately, several automakers are trying to follow in the footsteps of the California-based Tesla Motors and give us some sexy yet environmentally friendly cars. Honestly, it just can’t happen soon enough.

A few years ago, a guy (who drove a minivan) tried to convince me that the car you drive has nothing to do with who you are. But we all know that it says as much about you as the music you listen to, the clothes you choose to wear and the style of home you live in. That’s not a shallow indictment of an individual’s strengths and shortcomings, but rather an outward indication of what matters is most important to them.

Perhaps what this survey is saying is that it really is what’s inside – or in this case, under the hood – that counts. What we need now are more cars that take that inner beauty and look as good on the outside as they do under the hood.

Apparently, Tom Cruise was right on the money when he uttered those much-quoted words: “Porsche. There is no substitute.” (Risky Business, 1983.)

According to a survey released earlier this month by New York City-based Luxury Institute, wealthy U.S. consumers still see Porsche as the world’s most prestigious luxury automotive brand. The poll was part of the 2008 Luxury Brand Status Index survey, and asked the opinions of 1,642 Americans with an average net worth of $3.7 million.

Porsche might have led the pack, but was followed closely by Lexus and Mercedes. Surprisingly, no Italian brands made the survey’s top 12. Other brands that did make the cut with consumers were (listed alphabetically) Acura, Audi, BMW, Cadillac, Infiniti, Jaguar, Land Rover, Lincoln and Volvo.
