Helping to fuel the rumors of a possible C7 Corvette ZR1 is the news that General Motors has filed a trademark application for the “LT5” name with the United States Patent and Trademark Office. The Trademark Application dated on September 19, 2016 specifies the name will be used for “Engines for automobiles, sport utility vehicles, trucks and vans”.
In addition to the trademark application for “LT5”, General Motors has submitted a new application for the “LTX” trademark that will also be used for automobile engines.
This is the second time that General Motors has submitted the trademark applications for “LT5” and “LTX”. The previous applications were filed in April 2013.
GM has to show that the names they are filing for are for real-world products or services. Trademark applicants have three years to submit a “Statement of Use” document to the USPTO attesting to those uses. It’s believed that GM ran out of time on the original applications and the new applications restart the clock.
It’s worth noting that General Motors also submitted a trademark application for ZR1 back in May 2016 to be used for “motor land vehicles, namely, automobiles”.
It’s been rumored that GM is working on a new engine for the C8 Corvette that would make in the neighborhood of 750 hp. However, the speculation is, and this all speculation, the engine may first see production as the LT5 V8 for the C7 Corvette ZR1. Whether it will be a newly-designed engine or a variant of the Z06’s LT4 also remains a mystery.
