Ummm, many cars using LEDs still use projector lenses. Corolla, Accord, Porsches, Accuras, Mercedes, etc etc.

Did I say HIDs? Nope, question was regarding the lenses, not the light source.

Looks ridiculous with big unlit projector lenses in the middle of a split light array.

waht?

HID = high intensity discharge which are tungsten electrodes encased in xenon filled bulbs. Can be used in reflector based light assemblies or in projector lense assemblies

LED = light emitting diodes which can also be used in reflector based assemblies or projector lense assemblies.

Was just wondering whether the projector lenses of the refresh were headlights or high beams only. Appears they are high beams only which means they're never lit unless highs are on. Looks weird because typically projectors are used as the main lights when equipped regardless of HIDs or LEDs.

they turn on at night

This is the El-Cheapo refresh. Very little actual content. Fascia change costs are minimal (plastic).

Side stamping press changes? Not gonna do it.

Make the new tailights fill the old gap so we can keep costs low and profit high.

Headlamps are over a million in tooling, taillamps if LED would be up there as well.

New front and rear fascia? Another couple of million up front for fascia and grille and another 3/4 to a million for the rear fascia.


Still far from "cheap"

And Buick. My Lacrosse has steerable projector beam headlamps.



And to be clear, the decision to not change the ZL1 look up front was made over 2 years ago. It is not remotely possible they are responding the SS/LT reveal.

They will sell just as many ZL1s whether it has the fascia changed or not. It's not why people buy that car. So no reason to change and as pointed out, it needs as much airflow as possible.

Absolutely NOT what I am saying...

I made the note about the bumper change only because that’s what was done by GM to integrate the design.

However, they spent time and money to totally redesign the tail lights. Design and engineering time and costs. Investment in totally new injection dies; probably a new supplier.

They could’ve integrated the tail light better with the tail light design.


@waterman, that’s, bud!

There are likely two key reasons why the front of the ZL1 was not changed. As Number 3 pointed out, the decision to NOT change it was made long before anyone without a GM ID badge plus high security clearance ever saw the SS front fascia. The main reason to NOT change it is that a lot of engineering man-hours go into even a modest refresh. So if a low volume, high performance variant has a unique fascia, the engineering work to refresh it is going to slot in BEHIND the work to refresh higher volume variants.

Because of how important cooling and aero is to the performance of the ZL1, having a winning solution in hand means you have time to work on the refresh, if you refresh it at all. It took work to integrate the flowtie into the SS fascia, as much as you all "love" it. To do similar work at the same time for ZL1, which didn't need the work, could have meant something else didn't make timing in the mainstream models.

Gunkk nailed the 2nd key reason why ZL1 maintained current fascia, so I'll shut up and let his words speak....

The ZL1 is a low production numbers car. To change the fascia is at Least several million in tooling and engineering. No payback... wait till gen 7....

What a dumb article... as mentioned here 5th gen ZL1 refresh also just got the new rearend


Also take a look at Ford. GT350 is also keeping it's old design compared to the 18 refresh - even the new GT500 will keep the 2015 styled headlight and not the refresh.


Engineering a good airflow is just too complex to refresh the highend models completely - also they are already in a niche market for performance enthusiasts for way more money, so don't fall into the 3 year fatigue cycle like the base models
