The Q50 microsite is not specific. The videos for other Infiniti models say laser...but who knows if they are correct. The text doesn't say.

Laser was used on older Japanese cars (Lexus/Infiniti including my QX56), other used radar. Now I thought everyone uses radar which is less affected by dirt or bad weather.

Does anyone know if the Q50 is radar or laser?

How do you know?
Sinecure is a sales rep at Infiniti and knows his stuff! He's been VERY forthcoming as well as clearing up misconceptions and giving us insider information that is not confidential. If he says Radar, I'd believe him.

So I've never had intelligent cruise or lane departure. I was just wondering - if for example you needed to swerve to avoid something in front of you in the freeway (like swerve to the shoulder or something like that if you don't think you can break in time), would these systems prevent you from doing so?

Laser was the previous generation system. The new system uses radar and input from the forward-facing camera. I believe there are 3 radar systems in the vehicle. The big ugly one is hidden behind a lower grille panel beneath the turn signal up front. The other two are in the rear quarter panels (or somewhere in the rear) and provide the blind spot warnings and assistance.

I remember specifically asking about these during the car's debut at 2 local dealerships here, when you could sit and stare but not drive. The 2 corporate experts they had on hand knew everything in detail. My question started out as "what's the deal with the lower fascia panels not matching", below the turn signals.

Pretty fascinating nerd reading over here.

Which panels?

cruise control

How does the adaptive cruise control actually work? In the new TV commercial, there seems to be a sound alarm and a picture alarm on the dashboard; then the driver steps on the brake. The point of the commercial is that it can see beyond the vehicle in front of you. How does it do that?

I was under the impression that the adaptive cruise control automatically controlled the distance between cars. Are there two types of controls - warning alarm for cars down the road and automatic for the car right in front of you?

The system discourages behaviors.

I recently went to swerve to the right to go around a car stopped in traffic.

The car applied the brakes, pushed back on the gas pedal and I believe made it harder to turn the steering wheel as if I was changing lanes without signalling

The ad is highlighting the Forward Collision Warning and Intervention system. That is not adaptive cruise control.

The car "sees" the vehicle beyond the one in front of your car by bouncing the radar signal off the ground directly beneath the car in front of you.

Here's my crappy 5 minute MS Paint version.

That is where the radar is on my QX56 and not the best location. Most 2014 models have it in the center of the front grille. MB and Cadillac have different front grille emblems, the one with radar looking like a flat disk with the MB star or Cadillac crest on it. I'm a bit surprised they mounted it that low.

This what the system looks like on a Mercedes E-class or S-class:



Note, the LED headlights don't seem to adaptive highbeams, which apparently made it to the US on MB and Audi models directly. BMW seems to have included the technology, but the owner needs to have the electronics reconfigured with 'coding' to get the feature to work (at least that worked with 2013 7-series models). The A4/S5/3-series class of vehicles generally doesn't have LEDs nor adaptive headlights.
