1970 Chevy Camaro gets 650-hp crate engine for SEMA

The latest edition of the Chevrolet Performance catalog arrives at the 2015 SEMA Show, and to demonstrate the insane creations that are possible with it, the company has a seriously powerful machine in tow. This custom 1970 Camaro RS boasts the new LT4 crate engine that makes a staggering 650 horsepower and 650 pound-feet of torque. The offering gives hot rod builders the ability to put the Corvette Z06's 6.2-liter supercharged V8 into any project where they can make the mill fit. This Hyper Blue Metallic Camaro should offer neck-snapping performance with its massively powerful engine and a T-56 Super Magnum six-speed manual gearbox. Chevy's show car is about more than just packing copious horsepower into a classic shape, though. The builders also overhaul the suspension with coilovers at the front and rear, in addition to a four-link setup at the back. Behind the 19-inch aluminum wheels, the coupe has Z06-based brakes at both ends. For better visibility, it wears LED headlights and taillights. Plus, the interior gets custom gauges and a six-point roll cage. With pieces like titanium intake valves and forged aluminum pistons, the LT4 crate engine comes ready to offer serious performance, but Chevy also gives builders a few options to fit their application. The mill is available with either wet- or dry-sump lubrication. Depending on the version, there are kits to fit front-end accessories, air conditioning, and power steering, as well. The new Chevy Performance catalog features other high-performance components like Z06-based parts for the standard Stingray and an array of performance upgrades for the 2016 Camaro, including suspension lowering kits, brake upgrades, and more. We look forward to seeing this vast collection of goodies at SEMA this year.

GM finds steering flaw, decides it doesn't warrant a recall

Guess what? General Motors is back in the spotlight for not recalling something. This time, though, not only does the company have an argument against a recall campaign, but its position is supported by the National Highway Traffic Safety Administration. According to The New York Times, over 50 owners of GM vehicles have reported instances of stuck or seized steering after driving long distances without moving the wheel. One owner complained to NHTSA that the "locked" steering of their 2013 Buick Verano caused a collision with a concrete barrier in a construction zone. Along with the 2013 to 2014 model year Verano sedans, Chevrolet Cruze and Malibu sedans are also affected. Considering the popularity of those models, GM needs to have a reason for not issuing a recall, right? "Based on a very low rate of occurrence – ranging from less than one half to less than two incidents per thousand vehicles – and the fact that the condition is remedied when the wheel is turned, GM determined this was not a safety issue," spokesman Alan Adler told The Times. The company has, however, issued a technical service bulletin for owners that complain of the problem. The fix is nothing more than a software update that is covered for 10 years or 150,000 miles from new. NHTSA cited GM's actions, along with descriptions of the problems from customers, in its decision not to issue a recall, with spokeswoman Catherine Howden saying, "the symptoms described would be a brief, perceptible change in steering feel that has little to no effect on the driver's ability to safely steer the vehicle." "When terms like 'notchy,' 'stick,' 'slip' or 'feel' are used, it does not indicate a meaningful increase in steering effort," Howden told The Times via email. What do you think? Is GM in the wrong here? Should there be a recall, or is the issue so limited as to not warrant one? Have your say in Comments.

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.
