2007 Chevrolet Silverado 3500: What's New

Vehicle Overview
The Silverado 1500 underwent a major redesign for 2007 — but its arrival late in 2006 means there are actually two different vehicles with the 2007 designation: the new generation detailed here, and the previous generation, which now has the Classic name added to it.

The truck’s major changes include exterior restyling, vastly improved interior quality, roomier cabins, higher maximum towing and payload capacities and improved gas mileage.

As before, the Silverado shares a platform with the Tahoe and Suburban full-size SUVs. These models were the first on this all-new platform, making their 2007-model debut earlier in 2006. General Motors has tried to share the best attributes among these different models — and the sister trucks from the GMC brand — while keeping them distinct. Even for one model, the varieties are a lot to wade through: The Silverado comes in regular, extended and Crew Cab body styles and offers short, standard and long cargo box lengths; there are eight powertrain combinations, five suspension packages and three trim levels. Of course there’s also rear- or four-wheel drive. Heavy-duty versions (2500 and up) hit dealerships in early 2007.

Exterior
The most obvious difference in the new Silverado is a departure from the eyebrow-looking headlights of the previous model and a move toward more conventional stacked headlights flanking an enormous grille. The windshield is more swept back, yet the nose is taller and more squared off. The end result is better aerodynamics, which plays a part in the improved fuel economy.

The official trim levels are WT (work truck), LT and LTZ. There’s also LS, but it is now an exterior styling option package. The Z71 Off Road package also has some exterior changes along with its suspension mods. The LT has chrome bumpers and the LTZ’s are body-colored. Unlike the Tahoe, which blends its bumper into the front end, the Silverado’s remains a separate entity. Wheels range from 17 to 20 inches in diameter.

The cargo bed lengths are 5 feet 8 inches, 6 feet 6 inches and 8 feet. Not all lengths are available with all cab styles and powertrains, though.

Interior
After years of promising higher-quality interiors, GM finally started to deliver in the new Tahoe. That quality now appears in the Silverado too — especially in the LTZ trim level — in the form of less-plasticky plastics and lower shine. The mouse-fur ceiling liner has been replaced by classier, woven fabric. The WT and LT trim levels share an altogether different but also improved interior design.

In addition to added front-seat legroom, headroom and hip room, Chevy made the interiors seem roomier by moving the dashboards down and forward a few inches. Storage capacity has grown thanks to a double glove compartment (in the WT and LT) and even-larger center storage consoles. Even the optional 40/20/40-split front seat offers a lockable bin in the center seat and another in its backrest/armrest. (Not really a bench, this configuration is like two bucket seats with a small seat between them that converts into a center armrest/console.)

Chevrolet says the rear seats are more supportive and offer more legroom in both extended and Crew Cabs. The crews have split rear seats that raise to provide more storage space. They’re optional in extended cabs, which now have Nissan Titan-style access doors, which open 170 degrees. They also have power windows in the higher trim levels.

Under the Hood
Powertrain changes aren’t dramatic in this generation. There are still 4.3-liter V-6 and 4.8-, 5.3- and 6.0-liter V-8 engines paired with a four-speed automatic transmission. The 5.3-liter engine includes fuel-saving cylinder-deactivation technology and is flexible — capable of running on E85 ethanol and/or gasoline. The 6.0-liter grants the maximum towing capacity of 10,500 pounds — which was the “segment’s best” until Ford announced that its 2007 F-150 will match it (“Nyah-nyah”). This capability also requires one of five suspension choices called NHT. The other four Z-based suspension names (like Z71) are for a smooth ride, enhanced (but not maximum) trailer towing and handling, offroad capability and street performance.

More interesting than the powertrains are Chevy’s moves toward other, more-refined systems that have been finding their way into SUVs and other trucks: Coil springs have replaced torsion bars in the front suspension, and the recirculating-ball steering has given way to the lighter, simpler and more precise rack-and-pinion design.

Safety
Antilock brakes are standard on all models. The StabiliTrak electronic stability system is standard on Crew Cabs and optional on extended cabs but not available on regular cabs. In addition to the required airbag complement, side curtain airbags are optional for all three body styles. They deploy along all the side windows in the event of a side impact or a rollover. Chevrolet says the front seat belt pretensioners are designed to cinch the belts in a rear-end collision as well as a frontal impact, intended to prevent occupants from flopping around and being injured.

The Silverado comes with OnStar, with the first year of Safe & Sound service free. This plan includes automatic OnStar notification in the event of a collision, stolen vehicle tracking and remote door unlocking should you lock your keys in the truck.

2500HD
The new trucks get new engines as well. The standard engine is a 6.0-liter V-8 that produces 353 hp and 373 pounds-feet of torque. A 6.6-liter turbo-diesel is optional; it makes 365 hp and 660 pounds-feet of torque. Both engines are mated to a six-speed automatic transmission.

The trucks are offered in regular, extended and crew cab configurations, with two cargo box lengths. GM says it has redesigned the tailgate to lessen its mass and make it easier to use and remove.

Both the interior and exterior have been redesigned to make Silverado HDs look different from their milder cousins. Differences include larger door-pull handles, plus a new grille, hood and front fenders. Back to top

3500
New Silverado 3500 trucks also get new engines. Standard is a 6.0-liter V-8 that produces 353 hp and 373 pounds-feet of torque. A 6.6-liter turbo-diesel is optional; it makes 365 hp and 660 pounds-feet of torque. Both engines are mated to a six-speed automatic transmission.

Dual rear wheels and an 8-foot cargo box are available on 3500 models. The trucks are offered in regular, extended and crew cab configurations, with two cargo box lengths. GM says it has redesigned the tailgate to lessen its mass and make it easier to use and remove.

Silverado Classic
While a redesigned Silverado pickup truck is gracing showrooms as an all-new 2007 model, the old Silverado lives on as the 2007 Silverado Classic.

Trim levels include a standard Silverado Classic 1500, as well as the heavy-duty Silverado Classic 1500HD, 2500HD and 3500. A hybrid version is also available, though its electric motor does not assist in driving duties as traditional hybrids’ do. A collection of cab sizes, drivetrains and trim levels mean Silverado Classic shoppers have many varieties to choose from.

A 195-hp, 4.3-liter V-6 is standard, but most buyers select one of the V-8s: a 285-hp 4.8-liter or a 295-hp 5.3-liter. A higher-output version of the 5.3-liter V-8 yields 310 hp. The SS version gets a high-output 6.0-liter V-8 that pumps out 345 hp and 380 pounds-feet of torque. Silverado Classics use either a four-speed automatic transmission or a five-speed manual. Antilock brakes are standard. Front airbags include a passenger-sensing system. Side airbags and an electronic stability system are not offered. Back to top
