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 looks to combat high theft rates on SUVs with added tech

The Cadillac Escalade has been at or near the top of most-stolen and insurance-loss lists for more than seven years, until it dropped to number six earlier this year. In 2011 it was fitted with a host of new security features to address its easy-to-override features and that has brought the number of thefts down, but when eight of the ten most stolen rides are large SUVs from General Motors, no one will argue that something else needs to be done.
Thus, GM has fitted this same theft-deterring tech to the 2015 Suburban, Tahoe and Yukon. The Suburban and Tahoe will get the steering lock that the Escalade and Yukon already get, plus bolted-down third-row seats to deter thefts like this, stronger door lock cylinders and shields, and side-cut keys to inhibit picking.
Additional security measures in a Theft Protection Package can be purchased for $395, consisting of sensors on the greenhouse glass and interior, an incline/tilt sensor and added "key control systems" to make it more difficult for the men in black balaclavas to steal what you bought.

Chevrolet SS previewed by Holden VF Commodore SS V show car

It won't be long before we see the official, production-ready Chevrolet SS sedan (hint: it will be revealed this weekend). And to tide us over until all of the official details are released about the US-spec version, we have this: the Holden VF Commodore SS V show car, a performance-oriented brother to the Calais V that debuted earlier in the week.
What we really want to know about the SS V is what lies underhood, but General Motors' Australian arm is keeping that under wraps until the Chevy model breaks cover this weekend. Nevertheless, it's obvious that the SS V will be a serious performer, with all sorts of aggressive cues driving that home on the car's exterior. Take a look at those 20-inch billet aluminum wheels that hide big Brembo brake calipers up front, the sculpted hood and front fascia, the wide air intakes with LED running lights and the quad exhaust pipes out back. It's like the Pontiac G8 GXP never even left us.
Inside, there's a sporty-looking interior with aluminum accents that mix in with black leather and suede surfaces, all tied together in the middle with an eight-inch MyLink touchscreen infotainment system. It looks great, and again, while we don't know anything regarding powertrain details, it makes us oh-so happy to see a manual shifter smack dab in the middle of the center console.
