GM will recall more than 3.3 million vehicles in China for suspension defect

BEIJING (Reuters) - General Motors' joint venture in China, Shanghai GM, will recall more than 3.3 million Buick, Chevrolet and Cadillac vehicles stating Oct. 20 because of a defect with the suspension system, China's market regulator said on Saturday. GM Shanghai said in a text message to Reuters that the suspension arm may be deformed under extreme operating conditions, but there are no known casualties related to the issue. The recall includes cars produced between 2013 and 2018, the State Administration for Market Regulation said in a statement. GM will contact those affected and repair the vehicles free of charge, it said.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

Indian tuner turns Chevy Optra into Mustang 'Eleanor' replica

If you are a big fan of automotive oddities, this may come as a little treat. If you are a Shelby or Mustang diehard, prepare to have your sensibilities violated.
The master fabricators at BigDaddyCustoms are the minds behind what you see above. At first, it appears to be a slightly misshapen custom Mustang, modeled after "Eleanor" from Gone In 60 Seconds, but upon further examination, something appears to be amiss. In fact, the custom shop, based in India, has created an Eleanor replica grafted upon a lowly Chevrolet Optra. While it may take a second for the Optra to ring a bell, you should recognize its badge-engineered sibling, the Daewoo Lacetti, used on Top Gear.
We don't know what star would opt for the Reasonably Priced Car in Shelby's clothing, but it's clearly someone more concerned with the aesthetic than the performance credentials of this automotive mash-up.
