First, let’s take a look back in history. The first time GM used the moniker was back in 1969.
The ZR-1 moniker (with a hyphen) first appeared on the C3 Corvette from 1969 through 1970. This hyphenated version of the name also appeared from 1990 to 1995 on the LT5-powered version of the car.
It disappeared for a while, but then returned without the hyphen from 2009 to 2013 with a supercharged LS9 boasting 638 horsepower. The original version of the name, ZR-1, still has a live trademark, but the story is a bit different for ZR1. The trademark for ZR1 was filed back in 1989, but was cancelled later in 2001.
The Z06 came out in 2014, but that didn’t kill rumors that an even more amazing Corvette, possibly with a mid-engine configuration, was still in the works. There’s no way to know for sure what GM has in mind with its trademark filings, but a new ‘Vette is a pretty good guess. Let’s hope it turns out to be right.
