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.

GM to trim Russian output, raise prices amid currency woes

General Motors is shutting down its factory in Russia's second largest city, St. Petersburg, from the middle of March until the middle of May as the country's currency, the ruble, continues to give economists fits. The ruble's value has plunged due not only to western sanctions, but a precipitous fall in oil prices. We knew these factors were already impacting the auto industry there, as Ford reported in its 2014 earnings statement, and now they're forcing GM to cut production at the factory, shown above, that is responsible for production of the Chevrolet Cruze and Opel Astra. Meanwhile, Automotive News is citing Russian outlet Kommersant as saying that GM has hiked its prices in the country by an average of 20 percent over the past two months. While a GM spokesman confirmed the St. Petersburg plant would be shut down for the two-month span reported by Kommersant and AN, he would not confirm the price increase.

German police Corvette promotes safe aftermarket tuning

The German organization Tune It! Safe! promotes safe, legal vehicle tuning in the country, and it probably doesn't have to worry about anyone breaking the law when this Polizei-themed Chevrolet Corvette is on the scene. The Vette is on display at the Essen Motor Show and is the group's latest police-wrapped tuner car, following models like the Brabus Rocket, Mercedes-Benz CLS, and AC Schnitzer-tuned BMW 123d in years past. Tikt Performance did the tuning this time, and the German company added a full carbon-fiber body kit for the Vette, including a front lip, side sills, rear spoiler, and relatively understated wheel flares. It also installed forged wheels that measure 19-inches in front and 20-inches in back and wrapped them with Hankook Ventus S1 Evo tires. To really let the coupe look the part of a proper Polizei car, the tuners included police lights from Hella and the appropriate blue-and-white wrap. Tikt left the 6.2-liter V8 alone to produce 460 horsepower and 465 pound-feet, and the power routes through a seven-speed manual. Even with the stock performance, this police-themed 'Vette would still look fantastic blasting down the Autobahn with the lights flashing. World premiere at the Essen Motor Show: initiative for safe tuning starts the new campaign year with TIKT Performance Corvette A powerful look for a powerful campaign: TUNE IT! SAFE! presents innovative design and maximum precision Innovative design, maximum precision and unique performance – with an enhanced Corvette, TUNE IT! SAFE! shows that attractive, creative tuning in no way has to conflict with legal requirements. In the new campaign year, the seventh generation of a sports car icon stands as a symbol and shining example of safe automobile tuning and 100 per cent driving fun. The campaign car of the initiative for safe tuning, sponsored by the Federal Ministry of Transport, the Association of Automobile Tuners (VDAT) as well as numerous other organisations and institutions, sees its premiere at the Essen Motor Show (Hall 10, Stand F104). TUNE IT! SAFE! also continues its partnership with premium tyre manufacturer Hankook. Tuning specialist TIKT Performance based in Upper Bavaria is responsible for the innovative conversion of the new TUNE IT! SAFE! police car.
