GM confirms 2015 Silverado, Sierra to get 8-speed automatic

When viewed alongside the next Ford F-150 and the Ram 1500, there is one thing that seems to be missing from the Chevrolet Silverado and GMC Sierra. Where the F-150 will rely on turbocharging and aluminum architecture and the Ram sports an eight-speed automatic and an air suspension, the General Motors twins lack a big, calling-card feature. They're very good, very refined trucks, but one could argue that they're not terribly innovative.
And while it might not be as flashy a feature as air suspension or a lightweight skin, the Silverado and Sierra will get their own eight-speed automatic for 2015, a transmission that will be paired with the company's Ecotec3 6.2-liter V8. The new cogswapper will also find its way into the GMC Yukon Denali, but for now, there's no indication why the Cadillac Escalade, Suburban, Tahoe and standard Yukon are being left out.
According to GM, the new gearbox is about the same size and weight as the current Hydra-Matic 6L80 six-speed. By the time the new powertrain combination enters production late this year, the EPA will almost certainly have gotten around to certifying the vehicles' fuel efficiency. Until then, feel free to speculate. The current Silverado with the 6.2 and six-speed auto returns 14 miles per gallon in the city and 20 on the highway. How much do you think the eight-speed will improve those figures? Scroll down for the official press blast from General Motors, and then head into Comments.

Chevy Colorado and GMC Canyon get trim levels reworked again

GM Authority reports that GM has fiddled with trim packages on the Chevrolet Colorado and GMC Canyon for the 2021 model year, eliminating the base trims on both pickups and implementing small price changes. When the new model year goes on sale, the Chevy will lose the rear-wheel drive Base Extended Cab with the automatic transmission that starts at $22,395 after a $1,095 destination charge. The new entry-level is going to be the Work Truck model with the extended cab in rear-wheel drive, starting at $26,595 assuming the destination charge holds steady. That represents a $4,200 jump over the base 2020 model. MSRPs for the entire Work Truck lineup, from base to the Crew Cab Long Box, rise by $400. Elsewhere in the Colorado line, the four Z71 trims go down by $100, while the two ZR2 trims increase by the same amount. Only the six LT trims don't see any change.  The GMC side is a bit more involved due to previously announced changes. The 2020 Canyon comes in SL, Base Canyon, SLE, SLT, All Terrain, and Denali steps. Last month, GM Authority reported the 2021 Canyon would give all that up for the new names Elevation Standard, Elevation, AT4, and Denali. Since the SL base model retires in 2021, the Elevation Standard takes over at the entry level. Unlike on the Colorado, which sheds one trim, the Canyon lineup gets pared from 20 total combinations of trims, cab sizes, and bed lengths, to 14 total combinations. But like the Colorado, due to the loss of the cheapest configuration, the least expensive 2021 Canyon becomes $4,200 more expensive than in 2020, assuming the destination price remains the same. What's more, the 2021 Elevation Standard pricing adds $700 or $800 to the prices of the 2020 Canyon base and SLE models. There are more increases up the range. The 2021 Elevation trim replaces a combination of SLE and SLT models, bumping prices up by up to $900. In 2020, the least expensive All Terrain model is the Extended Cab Cloth for $37,695. For next year, the least expensive AT4 trim is the Crew Cab Short Box for $39,295. Like-for-like, though, the AT4 represents a $300 premium over the 2020 All Terrain Crew Cab Short Box. Three Denali trims will still stand at the top of the heap, each one going up by $400 in 2021. Until GM details the equipment changes, we won't know how the new pricing equates to value.

2019 GMC Sierra revealed with CarbonPro bed and new diesel engine

It's only March, and it's already been one hell of a year for trucks. January's Detroit Auto Show saw the reveals of the 2019 Ram 1500, 2019 Ford Ranger and the 2019 Chevy Silverado. The Chicago Auto Show brought new versions of the Toyota Tacoma and Toyota Tundra TRD Pro. Today, we finally got our first look at the Silverado's twin, the 2019 GMC Sierra. The truck features new styling, a new diesel engine and — on the Sierra Denali — a carbon fiber bed. As with every new full-size truck, the Sierra is larger than the outgoing model in almost every dimension, though exact dimensions haven't been revealed. For reference, though, the Chevy Silverado's bed is 7-inches wider than before. The new Sierra grille is more upright than before and features new C-shaped lighting. The Denali gets LED headlights, tail lights and fog lights. Both SLT and Denali trims get unique 22-inch wheels. As we saw in spy photos, the Sierra's interior is mostly just a copy of the Silverado's with some chrome accents sprinkled throughout. If you like the current truck interiors, you'll be pleased with the new model. Those hoping for a wholesale change will be left wanting. The big improvements inside include a full-color heads-up display, trailer hitch assist apps and cameras, and the rear-camera mirror found in models like the Chevy Traverse and Cadillac CT6. Safety and convenience features include a surround-view camera, blind-spot monitoring, pedestrian detection and low-speed automatic braking. Like the Silverado, there's been a significant effort to cut weight in the new Sierra. The 2019 model loses as much as 360 pounds compared to the current truck. It uses aluminum for the doors, hood and tailgate. Steel is still used for the fenders, roof and standard cargo box. The Denali, however, gets the real surprise here. Available only on the top-tier trim, the bed box will be constructed of carbon fiber rather than steel, saving 62 pounds. Carbon fiber only replaces the steel inner panels and floor. GMC says the carbon fiber will also help scratch and corrosion resistance. SLT and Denali models also get a new MultiPro tailgate. This is unique to the Sierra and separate from the Silverado's power assist unit. A new feature that helps one get into and out of the bed using an assist handle. The tailgate step has a maximum weight capacity of 375 pounds. There multiple positions that allow customers to extend the bed, or drop the center vertically to gain easier access to the back.
