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.

GM claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.

GM puts 3 million miles on hydrogen fuel cell test fleet

Have General Motors' hydrogen fuel-cell vehicles emitted enough water vapor over the past six-plus years to equal the steam coming out of Old Faithful? Not exactly, but GM has released a few figures related to the Project Driveway initiative it began in 2007. The numbers are impressive, if not quite of the geyser-spouting variety. In all, the General converted 119 Chevrolet Equinox SUVs to run on hydrogen, and those vehicles have just collectively surpassed the 3 million mile mark. And if you were waiting for us to tell you that the distance equals a half-dozen round trips between the earth and the moon, well, there you go. The better news is that the SUVs have combined to save almost 158,000 gallons worth of gas, and some of the vehicles have more than 120,000 miles on them. More than 5,000 drivers have participated in the project. GM reached that landmark about 10 months after it announced that it was working with Honda to accelerate the development of hydrogen fuel-cell powertrain technology. The two companies estimated last summer that it may have something to sell to the public as soon as 2020. For now, you can check out General Motors' press release below. GM Fuel Cell Fleet Tops 3 Million Miles Chevrolet Equinox fuel cell vehicles driven in real world reach milestone DETROIT – General Motors' fleet of fuel cell vehicles recently passed 3 million miles of hydrogen-powered, real-world driving. Some individual vehicles have accumulated more than 120,000 miles. By GM's estimate, using hydrogen to power these vehicles, the fleet has avoided 157,894 gallons of gasoline consumption. This specially equipped fleet of Chevrolet Equinox Fuel Cell vehicles are part of GM's 119-vehicle Project Driveway program, which launched in 2007. Since then, more than 5,000 drivers have provided feedback on the functionality and drivability of fuel cell technology. "Hydrogen fuel cell technology is an important part of GM's advanced propulsion portfolio and we continue to make substantial progress in furthering this technology," said Charlie Freese, executive director of GM's global fuel cell engineering activities. "These vehicles have operated through seven full winters and a wide range of environmental conditions, proving that fuel cells can meet the demands of real-world drivers." Last year, GM announced two fuel cell-related collaborations.
