The interior of the eighth-generation Chevrolet Corvette is full of buttons and lights. One nobody was expecting to find, though, is a glowplug light.

That’s right, a light associated with the startup procedure of a diesel engine can be seen just under the check engine light in the instrument cluster of a 2021 Corvette found by Redditor u/refrigerator_runner.

It’s hard to find many close-up pictures of the area around the instrument panel in the Corvette, against which to compare this photo, but Doug Demuro’s review of the 2020 ‘Vette does show the dash, and it looks like the photo was taken from the warning light strip on the right side of the instrument screen.

The comments section from the post did have a few amusing suggestions as to why the light might be there. One suggested that it might actually be a donut light, while another suggested that maybe it’s evidence that GM is planning a Duramax version of the Corvette with 15,000 lbs of towing capability, which should help get your race tires to the track with ease.

Here’s What GM Told Us About That Diesel Glow Light

However, when we asked Chevrolet, a spokesperson told us that the explanation is much more simple: the light is simply there as a leftover.

“We appreciate the speculation, but that symbol was included as part of our standardization process,” a spokesperson told us in an email. “It is not indicative of any plans to add the feature to Corvette and we plan to remove the icon in the future.”

So, this is definitely not a cleverly hidden feature, although there’s no shortage of those in the C8 Corvette. Between the seats, a speaker features a subtle Corvette logo on the perforated section. The flags are also hidden in the rear window as the shaded dot pattern at the top of the glass. On the front windshield, meanwhile, Zora Arkus-Duntov, the father of the Corvette, can be seen in the lower corner of the glass.

All of which are nice nods to the history of one of the longest-lasting sports cars on earth which might have switched to a mid-engined layout but will, sensibly, not be powered by a diesel engine.
