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.

2016 Chevy Volt zaps into the Detroit Auto Show with big improvements [w/video]

If you need an example of how quickly the plug-in hybrid market is evolving, just take a quick glance at the 2016 Chevrolet Volt. For its freshly introduced new generation at the 2015 Detroit Auto Show, the sedan sports extra range, better efficiency and a host of other improvements to make the vehicle even easier to live with. A big portion of the model's improvements come from Chevy's second-gen Voltec propulsion system. The updated drive unit is 12 percent more efficient and sheds 100 pounds from the scales. The battery itself also drops 21 pounds, while growing in capacity to 18.3 kilowatt hours. It gives the Volt an electric range of up to 50 miles and offers a total driving distance of over 400 miles. In addition, the new 1.5-liter engine offers estimated 41 miles per gallon fuel economy (with no battery). The significant improvement in specs are certainly respectable, but the vast majority of buyers should notice the latest Volt's evolved styling first. Up front, there's a shiny new nose with a more modern take on Chevy's split grille. From there, the design slows back to a more svelte take rear with the original model's futuristic, square taillights not making the transition. Inside, Chevy simplifies the infotainment system and now offers seating for three in the back. Check it all out in the gallery, above, to see how far the latest model has come. Chevrolet Introduces All-New 2016 Volt New model features expressive, sleek design and delivers 50 miles of EV range DETROIT – Chevrolet today unveiled the all-new 2016 Volt electric car with extended range, showcasing a sleeker, sportier design that offers 50 miles of EV range, greater efficiency and stronger acceleration. The Volt's new, efficient propulsion system will offer a General Motors'-estimated total driving range of more than 400 miles and with regular charging, owners are expected to travel more than 1,000 miles on average between gas fill-ups. "The 2016 Chevrolet Volt provides our owners with a no-compromise electric driving experience," said Alan Batey, president of GM North America. "We believe our engineering prowess combined with data from thousands of customers allows us to deliver the most capable plug-in vehicle in the industry." The 2016 Chevrolet Volt's technology and range advancements are complemented by a design that blends sculpted, muscular proportions with aerodynamic efficiency, and an all-new interior with seating for five and improved functionality.

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.
