GM trucks get hybrid versions, but you'll probably never see one

A few years ago, General Motors sold hybrid versions of its Chevy Silverado and GMC Sierra pickups. They weren't very good, using GM's old two-mode hybrid system that resulted in only negligible fuel economy gains. But GM's trying again, launching eAssist models of the 2016 Silverado and Sierra that are said to offer 2-mpg improvements in city, highway, and combined fuel economy ratings. Problem is, you probably won't be able to get one. Only 700 eAssist trucks will be made for the 2016 model year – 500 Silverados and 200 Sierras. When you consider that GM moved 824,683 examples of its light-duty pickups in 2015, this small run represents 0.08-percent of all Silverado/Sierra production, and GM says it "will monitor the market closely ... and adjust as appropriate moving forward." But that's not the only limitation. The eAssist trucks will only be sold through California dealers. For the Silverado, eAssist can only be optioned on the 1500 Crew Cab 1LT 2WD model, and for the Sierra, the fuel-saving technology is solely available on the 1500 SLT Crew Cab 2WD model with the SLT Premium Plus package. Granted, in terms of the Sierra, that means you get niceties like LED headlights and taillights, Apple CarPlay and Android Auto, Bose premium audio, heated seats and steering wheel, lane keep assist, and more. In the trucks, eAssist combines a small electric motor and 0.45-kWh battery pack with the pickups' 5.3-liter V8. GM estimates total output of 355 horsepower and 383 pound-feet of torque – no more horsepower than the non-eAssist trucks, but three more pound-feet of torque. GM says the eAssist trucks can tow up to 9,400 pounds, and the battery only adds 100 pounds to the trucks' weight. The electric motor provides 13 hp and 44 lb-ft of torque for a boost of acceleration off the line, or during passing. It also allows the engine to run in four-cylinder mode for longer periods of time. eAssist uses regenerative braking to help power onboard electrical systems, and adds start/stop to the powertrain. Finally, the so-equipped trucks have a six-percent improvement in aerodynamics, thanks to a soft tonneau cover and active grille shutters in the front fascia. Great news is, the eAssist option is relatively inexpensive, only costing $500. But good luck getting your hands on one.

Recharge Wrap-up: Phoenix Cars delivers ZEUS to Navy, Volt saves gas compared to i-MiEV

Phoenix Cars has delivered its first Zero Emissions Utility Shuttle (ZEUS) flatbed truck to the US Navy. The electric flatbed will be used to transport maintenance materials around Naval Base Ventura County Port Hueneme. The Phoenix ZEUS features a 100-mile range, and can charge in just three hours. It also features vehicle-to-grid technology and direct power capability, allowing it to function as a mobile power station. ZEUS customers enjoy an eight-year/300,000-mile battery warranty and round-the-clock technical support from Phoenix. Phoenix launched an electric passenger shuttle last year, and years ago worked on an electric sport utility truck before shifting over to larger vehicles. Read more in the press release from Phoenix Cars. A man found that he used less gas by trading in his Mitsubishi i-MiEV for a Chevrolet Volt. Ben Rich saved fuel in part by using his Volt for road trips rather than needing to rent cars. Rich also found other benefits to driving a Volt, including more comfort, more freedom of movement and less range anxiety. Rich often had to turn off the heat in the winter to eke out precious miles in the Mitsubishi, which he needn't do in the Chevy, though he did have a gripe about the Volt using the gas motor to warm the car.

ChargePoint has tallied over 9 million charging sessions for a total of 65 gigawatt hours of energy. Based on national efficiency averages of three miles per kWh and 23.9 miles per gallon, this has saved 8.2 million gallons of gasoline and 60 million pounds of CO2. This accounts for what ChargePoint calls a "huge environmental impact." Read more in the release from ChargePoint below. The Environmental Impact of ChargePoint Drivers Campbell, Calif.– We all know electric vehicles (EV) have enormous environmental advantages over gas vehicles. Plug-in EVs reduce carbon-based greenhouse gases, improve air quality and reduce our dependence on fossil fuels. EV drivers on the ChargePoint network have had a huge environmental impact. With over 9 million charging sessions delivering 65 gigawatt hours of energy, EV drivers have avoided over 60 million pounds of CO2 and 8.2 million gallons of gasoline, and driven over 196 million gas-free miles. *Based on national averages: EV efficiency of 3 miles per kWh, gas efficiency of 23.9 mpg and a net savings of 0.924 pounds of CO2 per kWh.

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.
