C7 Corvette turbo with 1,000 horsepower promised from Hennessey

If you can't wait for the next-generation Chevrolet Corvette ZR1, Hennessey says they will have you covered. The Texas-based company has announced it will offer a spate of upgrades for the 2014 Corvette ranging from a range of bolt-on options all the way up to a 1,000-horsepower, twin-turbo system. Buyers can start with a cold air intake, cat-back exhaust or stainless steel long-tube headers, but Hennessey says it will also offer up three stages of forced induction mayhem should those bits and baubles not provide enough thrust.
Those choices start with a supercharger system good for up to 700 hp, though Hennessey will gladly ditch the blower in favor of two turbos. Doing so will spin the crank to the tune of 800 horsepower all the way up to a certifiably ludicrous 1,000 ponies. There's no word on how much these tricks will cost you - or when they will be available, as we're guessing they haven't gotten their hands on the car yet - but you can head over to the Hennessey site to drop them a line if you're curious.

GM recalling 250,000 SUVs over door electronics

After a door-fire investigation that dates back to February, the National Highway Traffic Safety Administration has officially announced a recall today that affects around 250,000 General Motors SUVs for a faulty driver's door module. The recall applies to the Buick Rainier, Chevrolet Trailblazer, GMC Envoy, Isuzu Ascender and Saab 9-7X from the 2006 and 2007 model years, as well as the 2006 Chevrolet Trailblazer EXT and GMC Envoy XL for vehicles sold and/or registered in the Snow Belt.
Road salt use in these midwestern and northern states can lead to corrosion of the driver's door module on these GMT360 and GMT370 vehicles, which allows water to come in contact with the circuit board. If shorted out, the vehicle's power door locks and power windows will not work, and could possibly lead to overheating and, in some circumstances, a fire. No official word on how many total vehicles caught on fire, but back in June, 28 fires had been reported to the government agency. A fix for the problem is still being worked out, but all affected vehicle owners will be notified by GM.

GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.
