GM to build outgoing Silverado and Sierra until late 2019

As it has done with previous generations, General Motors is keeping the outgoing versions of its 1500 pickups in production despite the arrival of the all-new 2019 Chevrolet Silverado and 2019 GMC Sierra. The production of the previous, K2 generation models will begin to be wound down gradually, according to Automotive News, starting with crew cabs "early next year," and double and regular cab models following during "the early second half of next year." The old model trucks will continue to be built into "late 2019" based on market demand, GM's spokesperson Kim Carpenter said. The Chevrolet will go by the name Silverado LD, with the GMC Sierra designation still to be announced. Some of the outgoing models are built by sharing the assembly work between two GM plants. Partially finished Silverado and Sierra double cab bodies are shipped from Fort Wayne, Ind., to Oshawa, Ont., where the trucks are completed, including receiving paint. This eases the workload in Fort Wayne, where production of the new T1 generation trucks started in July 2018. In January, the Silao plant in Mexico will take on the duties of building new generation regular cab and crew cab trucks. Carpenter also said that the "Oshawa shuttle," as the shared production is called, has been very successful. As a result, 60,000 more trucks will be built than what the original production forecast initially called for. GM's latest quarterly profits, disclosed last week to be $1 billion, have been far higher than expected and will result in full-year profits far higher than what had been predicted in light of steel tariffs. GM isn't the only truck maker taking a similar multi-generation approach for 2019. Both the outgoing and redesigned Ram 1500 are in production, with the previous generation being dubbed Ram 1500 Classic. Related Video:

2015 Callaway Corvette Z06 gets new supercharger, adds $17K to starting price

Callaway's proud tradition of modifying Chevrolets is about to add a very significant chapter this weekend, as the company prepares to unveil a modified version of the 2015 Corvette Z06. The engine mods are simple, though we expect them to be very potent. That's because Chevy has replaced the factory supercharger with a new "GenThree" unit that's nearly a third larger than what's bolted on in Bowling Green. A new intercooler is also added, along with a new high-flow intake system. Beyond that, the changes are exclusively of the subtle cosmetic variety. There's new badging inside and out, as well as new engine covers, floormats and an underhood plaque. Naturally, there's documentation to verify the Callaway Z06's authenticity, and the comfort that comes with a three-year, 36,000-mile warranty. Callaway has priced the upgrade package at $16,995, in addition to the price of the stock Z06. While we're still waiting to hear official power figures, that seems like a reasonable asking price for what were wagering will be a major increase in power. The Callaway Z06 will debut this weekend at the National Corvette Museum's C7 Bash in Bowling Green, KY. Expect more details following the debut. Scroll down for the official press release.

Here's a sneak peek at the new package. Based on Chevrolet's track-proven Z06, Callaway engineers' no-compromise approach takes this Corvette to an astounding power level. While advertised Callaway horsepower and torque are pending final validation, the Callaway package adds Callaway's new GenThree supercharger system with 32% more displacement than the stock Z06 supercharger, improved manifold design and unique triple-element intercooling system. Callaway engineers recognize that a key contributor to maximizing power is reduction of inlet air temperature. By exposing the supercharger's large plenum area to outside ambient airflow, the design takes advantage of the significant charge air temperature reduction provided by convective cooling. The completely redesigned intercooling system also helps maintain nearly ambient charge air temperature with exceptionally low air restriction.

GM claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.
