Given the exposed headlamps, will the radar cross section of the C6 be significantly more? The headlamps act like reflectors, intensifying radar reflection.
Also, has anyone seen the positioning of the radiator? Is the radiator set more vertical now? This would also increase radar cross section.
I don't believe the exposed headlights are any worse radar wise then the older C5 style. However you may be right in worrying about the radiator. It looks like the C6 has a clear radar view to a highly reflective metalic radiator, while the C5's radiator was hidden by more non-reflective plastic (compisite) body work. If the the C6's radiator is also more vertical they it could be even worse. In addition, that open mouth will be a more accurate lazer radar. The older C5 design had no real vertical target and made accurate reading with lazer impossible. (beat a ticket for this very reason - on the stand, the officer couldn't identify what part of the car was his target and couldn't state that he held the target constant during the reading).
Anyway, I'm sure there are plenty of places to mount the V1.
The C5's plastic had nothing to do with its radar signature. Radar passes through the plastic with very little, if any, bounce. The reason that the C5 was so stealthy was because of the radiator's angle.
Of course, those with metallic paint are screwed anyway. The most radar and laser stealthy vehicle was a black C5 with no front plate and the lights down. As long as the C6 has a radiator with the same angle, it should have the same radar sig as the C5. However, the exposed lights will increase its laser signature.
Because of the steeply sloping angle of the front body work of these cars, the body does deflect the laser beam. Want to prove it too yourself? Take a 1/18th model, put it across the room and aim a laser pointer at it and observe the reflection. Therefore the body work in front of the C5’s radiator will deflect some of the laser beam. Since the C6’s path to the radiator is open (i.e. guppy mouth), I think more of the beam will actually strike the metal radiator and therefore make it a better laser target.
What leads you to conclude the exposed headlights (which are actually flared over with plastic covers) will be anymore of a radar target then the plastic body work that covered the headlights on the C5? I can't follow your logic here.

I agree that the position (angle) of the radiator is important to the radar cross section. Exposed headlights reflect light (radar waves) back to the sending unit. As you drive down a street at night, when your headlights illuminate a parked car, your headlights are strongly reflected back to you. The closer to straight on, the stronger the reflection.
Popups, because the headlamp mirror/lens is at a large angle away from straight ahead, will not reflect back as much al the radar signal. I think our plastic cars are transparent to the radar, it is the metal bits that will reflect back. Headlamp reflectors, being parabolic mirrors, produce a strong return signal.
Perhaps someone with a radar gun can do a few tests. If that radiator is vertical, that is, if it reflects radar straight back, then the C6 will be a larger radar target. Just wondering.
If this is the case then are you all forgetting the steal frame, and the engine block and heads? all metal, how bout the alternator and all the other periferals? Also as far as laser is concerned, jamers are leagle for laser.
If this is the case, then are you all forgetting the steel frame, and .....
No, not forgetting about those components, not much you can do about many of them.
However, tilting the radiator may reduce the radar signature by reflecting some of the beam away from the direction of the receiver. (Thus "hiding" the motor, etc. that is behind the radiator.) Headlamps pointed downwards (pop ups in the daytime) will not act as mirrors reflecting the radar beam back at the sender.

The laser beam works best when it hits reflective surfaces. It's a laser. The radiator is black and angled, not exactly the most reflective thing. Thus, the lights and license plate are the best targets. Ask any of the forum police officers, they'll confirm this.

I never concluded that. Where did you get that from? Reread what I posted. I stated that the exposed headlights present more of a laser target, not radar.
Actually, the response/reflection of a laser is more of function of it's wavelength. Certain lasers respond better to "reflective" surfaces, while others don't.
The C5's plastic had nothing to do with its radar signature. Radar passes through the plastic with very little, if any, bounce. The reason that the C5 was so stealthy was because of the radiator's angle.
In Dave MclCelland's book, he says that a 22 degree tilt was chosen for the radiator after testing it in real world conditions with all existing radar guns. This angle seemed to reflect back the least amount of beams.
As far as paint, it doesn't make any difference with laser guns does it? That's just about all they use in so cal now.

It does, to a point. Testing found that a black C5 with the lights down and no front plate (and, I would gather, no fog lights) had the smallest signature for both radar and laser.

Is that really true? I haven't read his book yet (was hoping to get it for christmas....but didn't). I'd be amazed and pleased to discover that they actually put effort into reducing the car's radar signature.

How about GM offering as an option a 25 W pulsed chemical or copper-vapor laser with a steerable beam. That way, when you get hit a by a measly little Class I or Class II laser speed-gun, you can fire back and blind the cop or else melt his face. It's not cost effective to come up with a laser jammer/diffuser (nor could you get enough onboard power to do so)..I assume you were kidding, right?

Thats quite an appauling statement. And would be highly illegal and immoral.
There are legal, low powered, safe laser jammers out there that work.

The reviews I've read say they don't work. Can you point me to a review a devises that work.
You do realize I was joking, right????? You're a EE, right? Do you know that a 25 W Cu vapor laser is powerful enough to burn through steel plate (when the laser is tuned to the 500-ish nm range), when properly tuned and focused....I worked with a variety of lasers for a few years in hydrodynamics research (flow visualize) as well as in-water detection systems. This laser at 25W peak power, also took 50 amps at 480V to drive...I don't think one's going to get that power and current out a 12V or 42V system...it was, i repeat a joke!!!!
As for being immoral, or amoral...when morality is always in the eye of the beholder.
