GM applies for LT5, LTX trademarks... are new small block variants coming?

Recently discovered General Motors trademark applications for LT4, LT5, LT88 and LTX have observers wondering what kind of high-performance offerings could be on their way. A new LT4 would mark a return of the engine designation first used on the Corvette Grand Sport, SLP Pontiac Firehawk and SLP Chevrolet Camaro SS from 1996 and 1997. Supposition at Corvette Forum - which provided advance intel on the C7 like these leaked images - believes a new LT4 could go into the high-performance trim of the next-gen, 2015 Camaro that would be more powerful than the 580-horsepower Camaro ZL1.
Seeing an LT5 again would also be déjà vu - in its former life it was a 5.7-liter V8 for the C4 Corvette ZR-1 from 1990-1994 designed by Lotus, producing from 370 hp to 405 hp. A mix of rumor and hope is that the new LT5 will be a supercharged evolution of the 6.2-liter LT1 (pictured) placed in the new C7 Corvette, and that it will go into the C7 version of the ZR1 pumping out something like 700 hp.
The LTX trademark is, as with that last letter, a complete mystery. If the "X" isn't a generic way to denote the whole LT family, it's wondered if it LTX could refer to a crate motor offering like the LSX.

Artist imagines eerie world where cars have no wheels

The wheel ranks right up there with the telescope and four-slice toaster in the pantheon of inventions that have moved humankind forward. But what if a circle in three dimensions had never occurred to anyone, and we all had just moved on without it? Perhaps we'd be driving around in Lucas Motors Landspeeders with anti-gravity engines. Or maybe we'd have the same cars we do today, just without wheels.
That's the thought experiment that seems to have led French photographer Renaud Marion to create his six-image series called Air Drive. The shots depict cars throughout many eras of motoring that look normal except for one thing: they have no wheels. The models used include a Jaguar XK120, Cadillac DeVille (shown above), Chevrolet El Camino and Camaro, and Mercedes-Benz SL and 300 roadsters.
Perhaps one day when our future becomes our past, you'll be able to walk the street and see with your own eyes the rust and patina of age on our nation's fleet of floating cars. Until then, Monsieur Marion's photographs will have to do.
