Next Corvette ZR1 to get 700 horsepower?

Word has it General Motors may offer as much as 700 horsepower in the C7 Corvette ZR1. Motor Trend reports the next Corvette Z06 will continue to rely on its naturally aspirated 7.0-liter V8 engine for thrust, but the lump will deliver substantially more power. How much more? MT says the engine could deliver up to 600 ponies. That's a jump of 95 horsepower over the current Z06, though no figures have been finalized as of yet. Right now, GM is reportedly waiting to see what sort of grunt it can glean from the next ZR1.
The automaker has already made it clear it will resurrect the LT5 name for the new supercharged V8, and if GM is already pulling 600 from the Z06, the big dog ZR1 would theoretically offer 700 horsepower. Either way, the range-topping Corvette will be suitably insulated from its less potent siblings. Stay tuned. We aren't likely to see the Z06 for at least a year, with the ZR1 trailing along at some point there after.

Feds open investigation into Chevy Express, Ford Freestar rust issues

'Tis the season... for road salt. And with that, comes rust. And what does rust bring? Well, for Ford and General Motors, a National Highway Traffic Safety Administration investigation. According to The Detroit News, NHTSA is looking into potential recalls issues with Chevrolet Express vans and Ford Freestar minivans.
The feds have received five complaints that rust has caused leaking fuel filler pipes on 2003 Express vans. Separately, seven complaints have been filed over excessive rust in the rear wheel wells of 2004 Ford Freestar and Mercury Monterey minivans. The Freestar and Monterey went out of production in 2007. Neither issue has resulted in any crashes or injuries, according to the report.

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.
