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 Chevrolet Camaro First Drive [w/video]

The Autoblog gang was downright stoked to learn the 2016 Chevy Camaro was next on our test-car docket. Then we found out it was the V6 model. Buzzkill. We were hoping for the snorting V8, or at least the spunky new turbo four-cylinder. The V6? Meh. We've been driving V6 Camaros for, like, six years. It's what you buy if you can't afford anything better, or so say horsepower snobs as they wrinkle their noses and cut their coffee with 93 octane. But after a week with the six-pot Camaro, we'll admit it: we were wrong. The all-new 3.6-liter V6 is strong, sounds good, and is damn fun to drive. Its 335 horsepower and 284 pound-feet of torque appear modest by modern standards, but they power the Camaro to 60 miles per hour in 5.1 seconds with the automatic, or in the case of our manual-equipped test car, 5.2 seconds. That's almost half a second quicker than the new turbo four-cylinder model. Yes, it has the same displacement as the old V6. No, it's not the same engine. Upon closer inspection, the V6's potency shouldn't come as a surprise. This engine is from General Motors' newest family of dual-overhead cam powerplants that launched in the Cadillac CTS and ATS. Yes, it has the same displacement as the old V6. No, it's not the same engine. Don't be fooled, and don't underestimate it at stoplights. The strapping V6 is unsuspectingly good, but it's just one of many improvements for the sixth-generation Camaro. Chevy's coupe is lighter, faster, and more modern looking inside and out. It starts with a rear-wheel-drive chassis donated from the Cadillac ATS, though about 70 percent of the components are unique to the Camaro. The 2016 model is about two inches shorter in length (thanks to a shorter wheelbase) and about an inch has been removed from height and width compared to the 2015 model. These lighter underpinnings jumpstarted the Camaro's weight-loss plan, and thanks to extensive use of aluminum, the V6 with the new eight-speed automatic transmission weighs 3,435 pounds – 294 less than its predecessor (the manual-transmission V6 Camaro weighs 3,448 pounds). The V8, meanwhile, sheds 223 pounds. One by one, these elements would merely enhance how the Camaro drives, but taken collectively, they invigorate the new model. It feels much more confident and agile in all circumstances. Put simply, it's a sportier car.

CNG-powered Chevy Sonic, Cruze headed your way

The value proposition for a Crazy Diamond Performance CNG ride was a little bit better before gas prices took a dive in the past month. Still, the Michigan-based company, which converts some of Chevrolet's compact vehicles to run on compressed natural gas, received approval late last month from the US Environmental Protection Agency (EPA) for two of its conversion models. And CNG is still pretty cheap. Crazy Diamond will start selling CNG versions of both the Chevrolet Cruze and Chevrolet Sonic. The startup will target fleet operators looking to cut both refueling costs and their carbon footprint. CNG can be found in much of the country in the low $2 range, while the average CO2 emissions are about 25 percent less than those of similar gas-powered vehicles. Average gas prices have tumbled by more than 30 cents a gallon in the last month, according to AAA, but they're still at close to $3. The two models will be able to go almost 300 miles on a full tank of CNG. Crazy Diamond said this summer that it would start selling converted a CNG-powered Cruze that delivers 130 horsepower for as low as $26,000. The turbocharged version goes for about $28,000. Take a look at Crazy Diamond Performance's celebratory press release below. Crazy Diamond Performance recieves EPA approval on its CNG Cruze and Sonic CDP receives EPA approval for its Mono-Fuel CNG Cruze and Sonic. Shelby Township, Michigan, October 30, 2014– Crazy Diamond Performance (CDP) receives EPA approval on its Mono-Fuel Compressed Natural Gas (CNG) Chevrolet Cruze and Chevrolet Sonic. Crazy Diamond Performance has received EPA approval on two new mono-fuel small passenger vehicles, the CNG Chevrolet Cruze and CNG Chevrolet Sonic. These new mono-fuel CNG platforms are the first of a series of small and fuel efficient vehicles coming from CDP, where cost, low emissions and reduced fuel consumption is important for not only fleet owners, but to the general public as well. "Soon to be available, are the 1.8L and 1.4L Cruze and Sonic CNG retrofit systems. These two vehicles represent a change in the status quo, with an OEM level integration of the fuel system and its components" states Michelle Fern, Executive Vice President CDP Inc. These vehicles provide flexibility for fleets looking to purchase a domestic small mono-fuel passenger sedan, but have not had an option until now. There are significant emissions benefits over its gasoline counterpart, with an average reduction in Carbon Dioxide (CO2) of 25%.
