All in a Day#8217;s Work

Equipped a 6.0L V-8 gasoline engine and GM transmission, base models of Silverado start at $36,440. Our came in at $49,629, the lion’s of that premium being the Duramax diesel and $1,200 transmission options. Backed up by a century#8217;s worth of heavy-duty fabrication, would GM#8217;s clean diesel drive ultimate power yet scrubbed when we turned that

And were the EPA ratings of 16/20

Initial Impression: Muscle

Christine: Are trucks getting or am I shrinking already? With no boards on this big boy, was one big abyss to step up and in #8211; a range to be exact. Would it be as of a stretch to drive this big boy for a week?

Scott: It was dark I got home and the truck had already delivered. When I pulled our driveway, my headlights glinted off the silver-tipped tailpipe poking out behind the rear wheel. It me of those big fat plastic bats little kids use to knock wiffle balls. I knew much then and there I was to like the stout Duramax/Allison package installed in this

I remember how much I liked my wiffle bat, but I ruined #8211; cracked it wide smacking a rock #8211; try to be a little easier on this

Look Pure pickup, pure

Chevrolet’s Pure Pickup package is geared towards and ruggedness while still comfort.

While Scott that fond of the previous grill and headlight treatment, he the new styling gave this a more aggressive muscular Both of us liked the overall interior was nicely laid out and and each control was easy to and find. For a truck intended for work, the light tones of the interior would not be our first for a work-a-billy ride, but the backseat for and rear cargo storage are to this truck’s practicality.

Handling-wise, the Silverado proved nimble and precise given its work truck status. not loaded, the ride was choppy and Beware of the shake and shimmy on roads.

In all fairness, the suspension is for a work truck and is really at its during towing and hauling. #8216;im a load and the ride out nicely, so it#8217;s understandable the ride would be stiff this big boy is unladen.

This 6.6L diesel with common rail direct delivery system has less of the and clack#8212;that notorious rattle#8212;inherent in its fuel system predecessors. The engineering in this clean engine reduces that further still, thanks to fuel injectors. The back and passenger seating and comfort is improved with Chevrolet#8217;s foam, seals and spray-on

Fuel-ability: Sweet and smooth

engineering enhancements were to the Duramax diesel to meet clean diesel specifications. A geometry turbocharger provides boost, from initial to its 120,000 rpm ceiling, with no turbo lag. Consistent means more efficient and lower emissions.

Fuel is metered through a redesigned pressure (26,000 psi) rail system featuring precision 7-hole fuel for thorough fuel atomization a larger exhaust gas recirculation cooler reduces NOx gases to the exhaust oxidation catalyst.

GM color-codes the fuel cap green to clean Ultra Low Sulfur (ULSD) or B5 (5% biodiesel) fuel While we fueled up with most new clean diesels are accepting blends of biodiesel.

And enough, the owner#8217;s manual #8220;It is acceptable to use diesel containing up to 5-percent biodiesel but the final blended fuel meet the same specification. and the used for making this must meet the latest of ASTM specification D 6751.#8221; concentrations are not covered by the warranty. And our mileage? 15.7 mpg, hwy/city.

We do feel that are being very conservative their new designs and emission We bet we’ll soon see acceptance of blends–and sure enough, we were writing this General Motors announced the of biodiesel blends up to B20. this will be only for trucks, but we can see GM expanding this to all vehicles.

The Enviro-meter: No smoke, no fumes

The Duramax 6.6L V-8 clean rated at 365 hp and 660 lb-ft of torque.

As is the of clean diesels, forget the black exhaust cough. pre-treatment in an upstream oxidizing exhaust gas passes through the particulate filter (DPF) particulate matter (soot) is and held in a honeycomb cell To keep the system working the DPF goes through periodic regeneration.

The onboard computer fuel injection to allow fuel to enter the filter at intervals where it flares off and increased temperatures that the accumulated soot. The resulting exhaust gas has a 93-percent soot and a 50-percent NOx reduction.

Because of the temperature required to burn off soot in the diesel particulate (DPF), the escaping exhaust gas be cooled. Four slots in the terminator provide airflow, and the exhaust gases create a effect and pull fresh air the terminator cooling the expelled with emissions on par with engines.

The real beauty of the Allison six-speed automatic transmission when it shifts into gears 5 and 6. At 0.71:1 and 0.61:1 this truck goes low gear power to high econo-cruise. At 65 mph in sixth gear, the rides at about 1500 Class-first range selection allows the driver to optimize conditions when towing.

Had we this truck on a highway we would have expected 20 mpg
