GM 6.2L V8 claims most powerful light-duty truck engine title

General Motors has officially captured the horsepower crown for mainstream pickup trucks with its 6.2-liter V8. The big mill, available in both the Chevrolet Silverado and GMC Sierra, comes to market with 420 horsepower and 460 pound-feet of torque, handily outdoing its two cross-town competitors, Ram (5.7-liter V8, 395 ponies and 407 lb-ft) and Ford (6.2-liter V8, 411 hp and 434 lb-ft).
The new GM 6.2 will take a bit of an investment, though. Those that want the extra thrust will need to go with either the LTZ or High Country trims from the Chevy, or the SLT and Denali trims from GMC, which are the two highest trim levels for the respective vehicles. Trim levels aside, if you're in the business of towing, GM has you covered. Optioned with the 6.2-liter V8 and the Max Trailering Package, owners will be able to pull 12,000 pounds, a hugely impressive figure.
We still aren't certain as to what sort of economy the new engine will get, but it'll probably be a bad bet for the fuel conscious. As for availability, expect to see the 6.2-liter trucks in showrooms later in the fall.

Watch Evo pick its 2015 Car of the Year in this epic video

With just a few days left in 2015, it's the perfect time to check out Evo's annual Car of the Year test to determine the greatest performance vehicle of the last 12 months. The writers' picks for the 11 finalists spanned a breadth of engaging models and included: Peugeot 208 GTi by Peugeot Sport, Lamborghini Aventador SV, Seat Leon Cupra Sub8, McLaren 675LT, Porsche 991 GT3 RS, Porsche Cayman GT4, Honda Civic Type R, Ferrari 488 GTB, Chevrolet Camaro Z/28, Lotus Evora 400, and Mercedes-AMG GT S. For the venue to test the mettle of these performance machines, Evo stuck close to home this year and visited the twisting roads at the beautiful north coast of Scotland. Racing brothers Marino and Dario Franchitti also came along for the ride to provide two more voices in the competitive challenge to determine a winner. Evo's video explains why each model deserves to be among such rarified company but doesn't gloss over their faults either. There can be only one winner, though. We don't want to spoil it, so check out the clip for magnificent views of these performance machines through the Scottish countryside.

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.
