2015 Chevrolet Colorado

The 2015 Chevrolet Colorado is a true midsize pickup truck that competes against the Nissan Frontier and Toyota Tacoma. With the addition of the new Colorado, General Motors is the only automaker to offer truck buyers the choice between a midsize, full-size, and a heavy-duty pickup.

2015 Chevrolet Colorado

At launch, there will be two engines powering the Colorado a 2.5-liter I-4, with an estimated 193 hp and 184 lb-ft of torque, and a 3.6-liter V-6, with an estimated 302 hp and 270 lb-ft. We have seen these engines in other GM products (Impala, Malibu, Equinox), but they have been re-tuned here for truck applications, with more bottom-end torque.

Both have direct injection and variable valve timing, and both will be backed by a six-speed automatic. Chevrolet hasn’t announced fuel economy estimates yet, but the truck will use active aero grille shutters, which will help improve mpg numbers.

By late 2015, a third unit will join the Chevrolet Colorado range a 2.8-liter Duramax four-cylinder diesel.

2015 Chevrolet Colorado comes only in extended- or crew-cab configurations, both offered with rear-wheel or four-wheel drive.

It will be produced in Wentzville, which starts cranking them out in time for a spring arrival. No pricing yet, but around $20,000 to start is a good guess.

2015 Chevrolet Silverado HD

General Motors has unveiled its latest version of the Chevy Silverado 2500 and 3500 HD pickup trucks. Although the suspension, frame and powertrains are effectively untouched, there are some significant changes that will be appreciated by heavy-duty truck shoppers. Here are some of the most notable changes:

Like the redesigned 2014 Silverado 1500, the 2015 Silverado HD got three completely redesigned cab configurations. Each was engineered to make them more aerodynamically “slippery,” stronger in case of a catastrophic crash or rollover, and better able to accommodate thicker door and window seals to create a quieter cabin. The biggest change to the lineup, as with the light duties, is in the Double-Cab structure, which used to be the extended cab.

Engineers have now eliminated the swing-out rear passenger doors in favor of traditional front-hinged doors. The addition of B-pillars also makes the overall cab structure stronger and safer. Additionally, the crew-cab models have newly sized front and rear doors to allow for better legroom for both front and rear passengers.

Probably the biggest improvement in the heavy-duty trucks comes in the form of a vastly superior interior gauge, center stack and console layout. Although there’s a great deal of similarity to the light-duty GM trucks, there are some small differences in switches and gauge styles. The 2015 pickups will offer GM’s new MyLink system with a larger, smartphone-like console screen, along with an info-packed driver screen centered between the speedometer and tachometer. There are tons of storage spaces hidden in the doors and wedged in the center console (when so equipped) and in the dash, all close at hand. One new feature we’re happy to see is the new integrated trailer brake controller, though it’s oddly positioned to the left of the steering wheel, high on the dash. The setup is within easy reach and well within the driver’s line of sight.

Although nothing has been done to the mechanicals of the suspension or frame, there are some new ratings numbers you should know about. The configuration with the highest maximum payload (likely to be the two-wheel-drive gas engine regular cab long bed) has been bumped up to a segment-leading 7,374 pounds (up from 7,222). Additionally, these new trucks have had their maximum conventional towing (meaning hitched to the rear bumper) number increase from 18,000 pounds to 19,600 pounds, which is also segment-leading. Finally, the maximum fifth-wheel gooseneck rating for the Silverado HD (likely a regular cab, 2WD Duramax long bed) has been increased from 22,500 pounds to 23,200 pounds, which isn’t close to the segment leader.

We’ve already mentioned that 2015 HDs will offer an integrated brake controller, but it’s worth noting Chevy and GMC will have StabiliTrak and trailer sway control as standard features for all 3500 models. In addition, software engineers made the grade braking features much more aggressive on both six-speed transmissions, gas or diesel. Add to this, when equipped, a more sharply tuned diesel exhaust brake and you can see why the Duramax could make a great choice for those hauling and towing heavy loads through mountain passes. We thought the previous model had it pretty well dialed in, but GM engineers tell us it’s even more capable and controlled now.

As noted, many of the exterior changes were motivated by a unique collaboration between designers and engineers as they figured out a way to meld the new light-duty look and design language onto the bigger work truck while addressing many nasty aero problems. As you might expect, special attention was paid to the truck’s front, keeping gaps as tight as possible, and then paying close attention to where they wanted the extra airflow to be directed. Hoods, headlights and taillights were completely remolded to give the truck a taller look from the outside without obstructing too much of the driver’s or passenger’s visibility. Design changes also help vastly improve interior noise levels by decreasing the amount of wind noise…

2015 GMC Sierra HD

2015 GMC Sierra HD

There’s really no better setting to reveal a new pickup truck than Texas. Specifically, the Texas State Fair. And that’s just what GMC did with revealing the new, highly revised 2015 GMC Sierra 2500 and 3500 HD trucks — vehicles that we refer to as “brutes in suits”.

With these new power tools comes reworked sheetmetal that provides improved aerodynamics, while a slew of user-friendly features make work easier, and a quieter, more thought-out cabin with more technology and higher-quality materials gives us gains in overall refinement. But for you number buffs, here’s the important stuff:

The 2015 GMC Sierra 3500 HD delivers a best-in-class payload rating of 7,374 pounds – and the highest conventional tow rating of 19,600 pounds (with a factory-installed, frame-mounted box-tube hitch), while the maximum fifth-wheel rating comes at 23,200 pounds. These are all improvements over the outgoing ratings of 21,700 pounds from the fifth wheel, 17,000 pounds of hitch towing, and 6,635 pounds of max payload.

It’s important to note that the updated line of 2015 GMC HD trucks still utilize the GMT900 frame and not the K2xx frame that the 2014 Sierra 1500 introduced — much like how the frames of the outgoing models kept with the GMT800 frame until the 2011 model year. We await a chassis refresh of sorts in the coming years.

The 2015 GMC HD trucks also keep with the same 6.0L V8 and the proven 6.6L Duramax diesel and Allison Transmission powertrains. Though because this is the case, GMC can continue to offer a bi-fuel option that pairs the gas engine with a compressed natural gas system, just as with the outgoing HD model.

The 2015 Sierra HD models will be available with 6’6” and 8’ box lengths that are said to be stronger, more durable, easier to use and offer greater cargo flexibility with features like the integrated CornerStep rear bumper, a trickle-down from the all-new 2014 Sierra 1500. The Double Cab body style also replaces the less practical extended cab variant.

Also integrated into the new HD Sierra trucks is the new interior layout from the 2014 Sierra 1500, which means it’s more intuitive than before, with the GMC IntelliLink infotainment system front and center, and the row of toggle-switches that control features like Lane Departure Warning and Rear Park Assist.

The 2015 Sierra HD line will also offer the Z71 off-road suspension package on SLE and SLT models, which adds  35mm deflective disk twin-tube shock absorbers, off-road jounce bumpers, 33mm front stabilizer bar and a skid plate package. The Denali HD model also comes back, for those who desire glamour to go with their grit…
