DETROIT (AP) -- General Motors is giving its big pickups a much-needed makeover.
The company unveiled new versions of its top-selling Chevrolet Silverado and GMC Sierra on Thursday, aiming to get them to showrooms by late spring or early summer.
The timing is good. Truck sales are growing after a five-year slump. And the new pickups replace models that were last revamped in 2007. That means GM dealers are offering pickups that are dated compared with newer Fords and Chryslers — and it is hurting sales.
GM says the 2014 trucks should put the company back in front. The trucks look a little more aggressive and aerodynamic. They will have quieter cabs, and updated steering, suspensions and brakes, GM says.
Gas mileage and pricing of the trucks was not released, although GM North American President Mark Reuss says customers will be surprised by the prices. He says the trucks are 200 pounds lighter than Ford and Chrysler competitors, which will help boost gas mileage.
The trucks should close the gap with Ford's F-150 and Chrysler's revamped Ram, especially if the engines are more powerful and efficient, says Jeff Schuster, senior vice president of forecasting for LMC Automotive, a Detroit-area industry consulting firm.
"The focus that they really put into these trucks, I think, gets them there," he said.
He was impressed by GM's attention to detail. For example, there's a step built into the rear bumper to gain access to the bed. And the doors fit into recesses in the body to make the trucks quieter.
GM offers three revamped engines: a 262-horsepower, 4.3-liter V-6 that GM says can tow a substantial trailer; a 325-horsepower, 5.3-liter V-8 that will get better mileage than the 22 mpg the current model gets on highways; and a 6.2-liter V-8 with 376 horsepower.
GM, which has been building Chevy trucks for 95 years, says the new models should hit the market at a good time.
Pickups are starting to sell again. The housing industry, which has a direct relationship to pickup sales, is strengthening and should be in even better shape when the weather improves this spring. Finally, the average age of a pickup in the U.S. is 10.4 years, GM says. More people will need to replace their aging vehicles.
GM needs to jump on those trends. It is having a tough time selling its current trucks against Ford's F-150 and Chrysler's Ram.
Full-size GM pickup sales fell 8 percent last month while competitors saw increases. At the end of November, GM had enough trucks on dealer lots to supply them for 139 days of sales. A 60-day supply is considered optimal.
Reuss says GM raised incentives to match competitors, and sales in early December are strong. The company didn't offer big deals last month and it hurt.
Reuss says GM intends to outsell Ford's F-Series, which is the top-selling vehicle in America, but he wouldn't put a time frame on reaching the goal.
About one in every 10 GM trucks sold this year came with a V-6 engine, and the rest with bigger V-8s. Reuss says he doesn't expect that to change much even though about 50 percent of Ford F-150s have the smaller engines to get better gas mileage.
GM plans to introduce new big SUVs and midsize pickup trucks in 2014, Reuss says. Also, the Silverado and Sierra will be updated more frequently.
The GMC and Chevy trucks, which are essentially the same vehicle, also will get six-speed automatic transmissions on all models, which should improve gas mileage. Some models now have older four-speed transmissions that aren't as efficient. The Sierra, though, is aimed at more upscale buyers who want luxury and practicality.
All three new engines have efficient direct fuel injection, and GM says they can switch seamlessly to run on only four cylinders to use less gas. The engines will have more torque and power than the older models.
