GM can't keep up with most popular pickup orders

With the market for pickup trucks at its best since before the recession, General Motors can't afford any hiccups with the launch of its new 2014 Chevrolet Silverado and GMC Sierra twins, but it sounds like the popularity of V8-powered trucks is causing some supply-chain issues. Bloomberg reports that GM is experiencing a shortage of 5.3-liter V8 engines because an unnamed parts supplier has been unable to keep up with demand. This is leading GM to restrict the number of V8 Silverado and Sierra trucks that Chevrolet and GMC dealers are allowed to order.
Although it's unclear how long it will take to resolve the parts shortage, GM doesn't have much time to sort it out, as a new Ford F-150 looms on the horizon. At launch, GM's fullsize trucks were offered only with a base 4.3-liter V6 and the 5.3-liter V8, but a burlier 6.2-liter V8 will be available soon. Interestingly, at least at the moment, GM truck buyers don't seem as willing to downsize to V6 power as buyers of the F-150, which gets some 42-percent of its sales from trucks equipped with its EcoBoost V6 engine (not including the normally aspirated base V6).
Working out the kinks in the Silverado and Sierra's supply chain couldn't be more important to the health of the company. Full-size pickups are a huge profit driver - in 2012, the trucks were said to make up about two-third of GM's total profits.

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.

GMC Hummer EV fan's Lego build is functional and even has Crab Mode

Lego creates some pretty amazing automotive models, but the Lego hobbyist community sometimes does better. Evidence of that comes to us in this fully-functional GMC Hummer EV Lego Technic model spotted by Road & Track and created by YouTube user Alain B. And while it's a one-off for now, there is the possibility it could become a kit you could bring home. As you can see in the video, the model looks the part with a body that closely matches the real thing. It's an impressively solid body, too, something that's sometimes difficult to achieve with Technic pieces. But that's only the tip of the iceberg. It's also got electric motors and is remote controlled. It has four-wheel-steering that can emulate the Hummer's famous Crab Mode setup. The fully independent suspension can raise for more ground clearance. And on top of all of that, it's even got a fully operational MultiPro tailgate and front trunk. The design is also listed on the Lego Ideas page. This is the site where Lego builders can submit their creations, and if they get enough votes, they'll be considered by the company for becoming a real production kit. You can visit the page at this link to lend your support (it doesn't cost anything). That page also reveals some other neat details, including the fact that it's made of about 2,200 pieces. While enough votes will get the design to be considered by Lego, there are other factors that determine whether it makes production. Some of them include getting the license from General Motors, and other undisclosed reasoning. But Lego has done a number of large, technical and somewhat pricey kits with licensing from other companies. So this seems like a great one for the company.
