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: Long Beach ePrix, London's new electric buses

London will put 51 new electric buses into service. With the addition of these buses, two more routes (in addition to one already in operation) will be all-electric. Transport for London plans to have all of central London's 300 single-decker buses running on electricity or hydrogen by 2020. "The expansion of London's electric bus fleet demonstrates our commitment to reducing emissions from public transport in London," says Deputy Mayor of London for Environment and Energy, Matthew Pencharz. "The Ultra Low Emission Zone that will be introduced in 2020 is the most ambitious measure of its kind taken to tackle air pollution anywhere in the world, and it will transform our bus fleet into a cleaner, greener and more pleasant way of travelling for Londoners."

Along with 10 Cruze vehicles, one 2015 Volt has been recalled because of a tie rod that might not have been tightened to the steering gear correctly, which could lead to a loss of steering control. Chevrolet will replace the steering gear assembly, supplied by Robert Bosch Automotive Steering, for free. There have been no reported injuries from this issue. Read more at Detroit News. The Formula E Long Beach ePrix will take place on April 2, 2016. For the second season of the electric racing series, Long Beach is the only confirmed US host, as the spot on the calendar previously held by Miami still remains to be determined. More than 20,000 fans attended the inaugural Long Beach ePrix earlier this year, where Nelson Piquet, Jr. took first place before going on to win the Drivers' Championship. "It's extremely exciting to welcome the ePrix back to Long Beach for a second year," says Long Beach Mayor Robert Garcia, "and we are hopeful that this demonstration of innovation, sustainability, and cutting edge technology will return to our city year after year."
