The USPS needs 180,000 new delivery vehicles, automakers gearing up to bid

Winning the New York City Taxi of Tomorrow tender was a huge prize for Nissan, even though the company is still working through the process of claiming its prize. The United States Postal Service has begun the process to take bids for a new delivery vehicle to replace the all-too-familiar Grumman Long Life Vehicle, and that will be a much larger plum for the automaker who wins it, perhaps worth more than six billion dollars. The Grumman LLV is an aluminum body covering a Chevrolet S-10 pickup chassis and General Motors' Iron Duke four-cylinder engine. The USPS bought them from 1987 to 1994, and the 163,000 of them still in service are a monumental drain on postal resources: they get roughly ten miles to the gallon instead of the quoted 16 mpg, drink up more than $530 million in fuel each year, and their constant repair needs like the balky sliding door and leaky windshields have led the service to increase the annual maintenance budget from $100 million to $500 million. A seat belt is about as modern as it gets for safety technology, and the USPS says that assuming things stay the same, it can't afford to run them beyond 2017. Last year it put out two triage requests for proposals seeking 10,000 new chassis and drivetrains for the Grumman and 10,000 new vehicles. The LLV is also too small for the modern mail system in which package delivery is growing and letter delivery is declining. The service says it doesn't have a fixed idea of the ideal "next-generation delivery vehicles," but it listed a number of requirements in its initial request and is open to any proposal. Carriers have some suggestions, though, saying they want better cupholders, sun visors that they can stuff letters behind, a driver's compartment free of slits that can swallow mail, and a backup camera. The request for information sent to automakers pegs the tender at 180,000 vehicles that would cost between $25,000 and $35,000 apiece, and it will hold a conference on February 18 to answer questions about the contract. GM is the only domestic maker to avow an interest, while Ford and Fiat-Chrysler have remained cagey. Yet with a possible $6.3 billion up for grabs and some new vans for sale that would be advertised on every block in the country, we have a feeling everyone will be listening closely come February 18. We also have a feeling the LeMons series is going to be flooded with Grummans come 2017. News Source: Wall Street Journal, Automotive News - sub.

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.

2015 Chevy Impala Bi-fuel burns CNG, starts at $37,385*

Currently, the only natural-gas-powered passenger car offered for sale by an OEM in the US is the Honda Civic Natural Gas. Starting this fall, that long-running CNG car will be joined by a CNG-burning 2015 Chevy Impala for both fleet and retail customers. General Motors announced today that the car will start at $37,385, plus an $825 destination charge. That comes to $38,210 before taxes and options. Those options include two trim lines, the base LS and the upper-level LT. Chevy doesn't break out the details in the press release announcing the price, but you can see the trim details for the standard gas-powered 2014 Impala here. Exact information on the 2015 models is not available just yet, but GM spokesman Chad Lyons told AutoblogGreen that the equipment that you see listed on the site for 2014 is "almost exactly the same" as what will be available for 2015. The 2015 Impala gets around 19 city mpg on CNG, but official EPA numbers are not yet available. That means the LS will come with 18-inch aluminum wheels, electric variable-assist power steering, projector-beam headlamps, and 10 air bags. The LT adds an eight-inch touch screen with MyLink, premium Cloth interior and dual-zone automatic climate controls. The cost for this upgrade is unspecified. For CNG purposes, we can ignore the numerical prefix used for the gas-powered LT trims, since that denominates the engine type, and all the CNG models use a 3.6-liter engine with hardened valves and valve seats that can better handle natural gas. The trunk capacity also drops from 18.8 cubic feet to 10 cu .ft. in order to fit in the CNG tank that holds the equivalent of 7.8 gallons of gas. That amount of CNG should move you 150 city miles, which is around 19 mpg, but official EPA numbers are not yet available. With the addition of the gasoline on board, the overall range is 500 city miles. The car burns CNG when available and switches to gas with "no interruption" either when the tank is empty or when the driver selects the gas tank. Find more details in the press release below. GM says the CNG Impala will will be available nationwide this fall. CNG is a growing fuel in the US, thanks in part to fracking. The Civic Natural Gas, which starts at $26,640, is growing towards a nationwide availability. Next year, for example, the Shell Eco-marathon Americas in Detroit will allow CNG for the first time.
