GM looks to combat high theft rates on SUVs with added tech

The Cadillac Escalade has been at or near the top of most-stolen and insurance-loss lists for more than seven years, until it dropped to number six earlier this year. In 2011 it was fitted with a host of new security features to address its easy-to-override features and that has brought the number of thefts down, but when eight of the ten most stolen rides are large SUVs from General Motors, no one will argue that something else needs to be done.
Thus, GM has fitted this same theft-deterring tech to the 2015 Suburban, Tahoe and Yukon. The Suburban and Tahoe will get the steering lock that the Escalade and Yukon already get, plus bolted-down third-row seats to deter thefts like this, stronger door lock cylinders and shields, and side-cut keys to inhibit picking.
Additional security measures in a Theft Protection Package can be purchased for $395, consisting of sensors on the greenhouse glass and interior, an incline/tilt sensor and added "key control systems" to make it more difficult for the men in black balaclavas to steal what you bought.

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.

No diesels in the running for 2016 Green Car Of The Year

It's a new era for the Green Car Of The Year. In the past, the theme of the award was to take a broad look at alternative powertrains and pick the best among them. "Clean diesels" from the Volkswagen group were often among the finalists and won the award twice. For the 2016 edition - which will be handed out at the LA Auto Show next month - not a single diesel made the list. There's little wonder why. Green Car Journal, which names the winner with a panel of experts, had to strip two VW brand vehicles of their past wins. The 2009 VW Jetta TDI, which won in 2008, and the 2010 Audi A3 TDI, which won in 2010, have both lost their titles now that the world knows about the "defeat devices" that VW installed in many of its TDI vehicles around the world. So, what does that leave us with for 2016? Two plug ins, a hybrid, and two gas vehicles. The two electric vehicle are the Audi A3 e-tron and the Chevy Volt, while the all-new Toyota Prius (which will come with a plug-in version later) is the lone pure hybrid. Rounding out the pack are two efficient gas models: the Hyundai Sonata and the Honda Civic. This is the tenth year for the Green Car Of The Year, and it will be interesting to see if diesels can come back into the award's good graces (for the record, no diesels were among the finalists in 2013, either) in the future. For now, we'd like to know who you think should win. You can read more about the finalists in the press release below and then cast your vote in our poll.
