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.

Recharge Wrap-up: 'Racing Extinction' Tesla, Wards praises 3 hybrids

The makers of Racing Extinction used a tricked out Tesla Model S for their movie. The artists and activists used the electric car as a platform to project images from nature in various cities to raise awareness about imperiled wildlife. In addition to a the high-powered projector, the Model S features a electroluminescent paint job that emits light to mimic creatures found in the wild, such as bioluminescent sea life. It also has a thermal imaging camera in the front of the car with a filter to view CO2 emissions. Check it out in the video above, and read more at Ecomento. WardsAuto has named the 2016 Hyundai Sonata Plug-In Hybrid's powertrain to its list of 10 Best Engines. As the first plug-in hybrid to make the list, WardsAuto World Editor-in-Chief Drew Winter praises Hyundai engineers for their "impeccable job blending fuel efficiency with refinement and daily usability." Wards notes the car's smooth transitions between electric and hybrid modes, and a well-connected six-speed automatic transmission. Other electrified vehicles to make the list are the 2016 Chevrolet Volt and 2016 Toyota Prius. Read more from Hyundai, at Green Car Reports. FEV's plug-in hybrid battery pack has gone into vehicle series production. The 10-kWh battery pack, developed by the German development services provider, offers an all-electric range of about 30 miles. FEV says its battery management algorithms are just as important as choosing the right battery hardware. "The core system for the battery development is our own mature battery management system (BMS), now in its third generation, that together with optimized algorithms allows a very reliable and stable control of the battery," says FEV's Dr. Michael Stapelbroek. Read more at Green Car Congress, or in the press release from FEV below. Hybrid Vehicle Goes Into Series Production FEV development competence consists of batteries, controls, as well as complete drive systems FEV has demonstrated competence in the development of alternative drive concepts for almost twenty years. Most recently, yet another plug-in hybrid vehicle has gone into series production with technology provided by the Aachen-based developer. In addition to using an innovative transmission concept which is based on a FEV patent, FEV also developed the battery technology of the plug-in hybrid vehicle to series production readiness.
