GM Trademarks LT5 and LTX Engine Names

GM Trademarks LT5 and LTX Engine Names

The LT nameplate has a long and storied performance history for Corvette and General Motors. Looks like a new chapter could well be added by the seventh generation of the ?Vette.

The LT1, of course, was a small block powerhouse for the Corvette from 1970 to 1972, and the name reappeared in the early 1990s for a motor used in the C4 Corvette, Camaro SS, and Pontiac Trans Am. Then there was the LT4, a high-performance rendition of the LT1, that came along for C4 Corvette Grand Sports, SLP Pontiac Firehawks, and SLP Camaro SS.

The LT name that stands above them all, however, is the LT5, the monster motor created by Lotus for the C4 Corvette ZR1 that featured a double overhead cam design and four valves per cylinder.

With the LT1 set to reappear as the base engine in the 2014 Corvette Stingray, it’s only natural to assume that GM might well be creating a new LT5 for its highest-performance vehicle, especially after gmauthority.com reported this week that the company has reapplied for the LT5 trademark, described as ?engines for automobiles, sport utility vehicles, trucks and vans.?

GM also reapplied for the LTX trademark. Gmauthority.com points out that could just be the umbrella name for the entire LT-engine family, but the website says ?we like to think ?LTX? could be the name of some range-topping motor in the works, as X is so-often tied to something extreme. Perhaps a crate motor, like the current LSX engine.?

The site also notes that a thread on Corvette Forum foresees the return of the LT4 name on a motor to be used in the new generation Camaro in 2015. They also pointed out that GM has refiled for the L88 name, which of course was used for the super rare high-performance engine in the 1960s.

All in all, looks like the good folks at GM still have plenty of performance tricks up their sleeves, just waiting to be revealed to enthusiasts over the next few years.
