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, Pilot will build EVgo fast chargers at 500 truck stops across U.S.

All of our maps showing electric vehicle charging stations across the U.S. are going to need an update. Today, General Motors, Pilot and EVgo announced plans to work together on a nationwide DC fast charging network. The plan calls for 2,000 charging stalls that can deliver up to 350 kW to be installed at up to 500 Pilot and Flying J travel centers in the U.S. The goal is to have DC fast chargers available in 50-mile intervals across the country. The new charging stations will feature GM's "Ultium Charge 360" branding and "Pilot Flying J" logos but will not be limited to drivers of GM EVs. The plugs will use CCS connectors and be available to anyone. GM EV owners can take advantage of benefits, including the ability to make exclusive reservations, get discounts on charging costs and streamline the charging process with Plug and Charge and in-vehicle apps that can provide real-time charger availability. The first installation phase will take place in 2023, and "the bulk of the installations" should be completed by 2025, EVgo CEO Kathy Zoi said during a conference call with reporters announcing the plan. "We're gonna get going immediately and commence all of that engineering and planning stuff," she said. "We've got a pretty orderly plan." Pilot CEO Shameek Konar said the company expects the new EV charging stations to coexist with the current fuel infrastructure. "An average Pilot Flying J location is about 10 acres," Konar said. "This will be in addition to all of our gas pumps. The way I think about it is, this is a new source of energy that is going to coexist with gas for quite some time. We can debate how long, but we need to serve both groups of customers." Installing DC fast chargers at hundreds of Pilot's travel centers — aka truck stops — means there should be food, drinks, restrooms, WiFi and even showers available while you wait for an EV to charge. Pilot recently announced its “New Horizons” plan that will invest $1 billion in upgrading Pilot travel centers with more premium amenities, including expanded seating and lounge areas. While the exact amount of time it will take to charge an EV using these new stations will vary on the EV and its current state of charge, most EVs can refill from a low state of charge to around 80 percent in 20-30 minutes on a fast charger. The new stations are future-proofed to deliver up to 350 kW, a charge rate that few EVs today can handle.

Camaro spy shots show subtly different grille, front fascia

It looks like there some changes in store for the Chevrolet Camaro - the only thing is that we just don't know what Chevy has up its sleeve. Looking at these spy shots, we'd initially be inclined to think that there is just a minor facelift or a new special edition, but upon closer inspection, there are a few oddities about this car that definitely have us intrigued.
The most obvious difference on this prototype is the slightly restyled front fascia with a smaller lower air inlet and the two-bar grille. Then we get to some of the car's mysterious details. For starters, this fascia has the SS vent above the grille, but it looks to be blocked off. Granted this could just be a one-off piece used for testing. What really piqued our interest was at the rear of the car where it has quad exhaust outlets that are used on the ZL1. Could this be the LS7-powered Camaro that we reported on back in December?
At this point, your guess is as good as ours as to what we're looking at here, so let us know in the comments what you think this could be.
