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.

Next-generation Chevrolet Colorado breaks cover in new spy photos

The next-generation Chevrolet Colorado broke cover in this fresh set of spy photos this week, giving us a glimpse of what to expect when GM's compact trucks are replaced in what is expected to be either 2023 or 2024.  Thanks to its still-extensive camouflage, this prototype doesn't give away a ton about the new Colorado's styling, but in profile, it appears as though the swoopy, upswept rear cab line might become a thing of the past. We wouldn't be surprised to see the new Colorado adopt a more angular, squared-off look more akin to that of its big brother, the half-ton Silverado. The Silverado is also expected to donate what may be the new Colorado's only powertrain. Taking a cue from Ford, Chevy is expected to offer the next-gen Colorado with just a turbocharged four-cylinder engine — the new corporate 2.7T in this instance. The large, 310-horsepower four-pot can easily take over for the 3.6L V6 currently available in the GM twins and one-up the 270-hp Ranger to boot. This would mark the end of both a V6 and diesel option being offered in GM's midsize trucks, and tracks with the company's slow, silent effort to eliminate lower-margin models. We say "trucks" because, well, whatever happens with Chevy is likely to translate to GMC. The Canyon will be due for replacement at the same time, and will likely carry on as a re-skin of Chevy's offering. We're not yet certain exactly when Chevrolet will start selling the next-gen Colorado, but given the reasonably complete state of this prototype, we expect it won't be long now. Rumors suggest it could hit the market in 2023 as a 2024 model.  Related Video: The Best Midsize Pickup: Ranger vs Gladiator vs Tacoma vs Colorado

Pics Aplenty: Meet the 2014 Chevrolet Silverado and GMC Sierra [w/poll]

Today was a pretty big day for General Motors, debuting the all-new Chevrolet Silverado and GMC Sierra light-duty pickup trucks ahead of their official showcase at the 2013 Detroit Auto Show. And now that the dust has settled at GM's big reveal event, we've had a chance to snap dozens of photos of the new pickup pair from every angle.
We already told you the important bits earlier today (click here in case you missed it), but let's recap. Under the hood are three new engines - a 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 (you know, a version of the small-block that'll also be found under the hood of the C7 Corvette), all mated to six-speed automatic transmissions. The 2014 model year marks the return of the Z71 off-road package with Rancho shocks, front tow hooks and beefier underbody protection. Inside, there's a host of new technology and a greater focus on better quality and refinement.
Some of the nitty-gritty specifics (like engine output numbers and fuel economy) have yet to be revealed, and since we haven't driven the finished products yet, it's hard to say how these trucks will fare against rivals like the Ram 1500 and Ford F-150. For now, we can only judge these two books by their covers, and while we do like the designs of the new trucks, we Autoblog staffers are torn on exactly which one looks best.
