2015 Chevy Spark will have lighter, smaller battery

As General Motors gets ready to release the 2015 Chevy Spark EV, it is retooling the Brownstown Battery Assembly to build a new battery system for the chirpy little electric car. The new Spark will lose a few pounds and kWh from its lithium-ion pack, but it will keep all of it's performance specs. The current Spark EV uses a 21-kWh lithium-ion battery pack with bits made by A123 Systems (known as B456 Systems during bankruptcy). For the 2015 model, GM is going to build a 19-kWh battery system in-house that will use 192 LG Chem cells. Losing a bit of energy capacity means that the battery system for the 2015 Spark EV will be 86 pounds lighter but it will keep the EPA-rated 82-mile range and 119 MPGe. The 2015 Spark EV also keeps its $26,685 (plus destination) starting price from the 2014 model. The car will once again qualify for a federal tax credit of up to $7,500. LG Chem also supplies the cells for GM's other plug-in vehicles from its facility in Western Michigan. The Brownstown production line currently builds the battery packs for the Chevy Volt, the Opel Ampera and the Cadillac ELR. You can read our first drive of the 2014 Chevy Spark here. Brownstown Battery Assembly Expands Capabilities Will build battery system for 2015 Chevrolet Spark EV 2014-05-14 DETROIT – General Motors will bring all its electric vehicle battery building capabilities in-house with production of battery systems for the 2015 Chevrolet Spark EV at its battery assembly plant in Brownstown, Mich. "Using our in-house engineering and manufacturing expertise enabled us to deliver a battery system that is more efficient and lighter than the 2014 Spark EV without sacrificing range," said Larry Nitz, executive director of GM global transmission and electrification engineering. "Our successful working relationship with LG Chem has allowed us to deliver a new battery system for the Spark EV that helps us to better leverage our economies of scale." A newly designed battery system features an overall storage capacity of 19 kWh and uses 192 lithium ion cells. The cells are produced at LG Chem's plant in Holland, Mich. The battery system weight of 474 lbs. is 86 pounds lighter than the system in the 2014 Spark EV. The Spark EV battery is built on a dedicated production line at Brownstown, which also manufactures complete battery packs for the Chevrolet Volt, Opel Ampera and Cadillac ELR.

2022 Chevy Silverado HD gains Multi-Flex tailgate as an option

GM is spreading the Multi-Pro Tailgate love around its truck lineup, and the Silverado HD is the latest pickup to gain the option. Just like the 2021 Silverado 1500, Chevy uses the “Multi-Flex” name for it in the HD, eschewing GMCÂ’s “Multi-Pro” branding for the bowtie vehicles. YouÂ’ll be able to option the tailgate on 2022 model year Silverado 2500HD and 3500HD models. ItÂ’ll be available optionally in every trim, so thereÂ’s no need to grab a more expensive trim to gain access to the trick tailgate — youÂ’re also not required to take it in higher trims. Functionality is the same as the standard Silverado and Sierra.  The primary gate opens and closes like any other tailgate out there. ThereÂ’s a primary gate load stopper that allows you to put the gate down and still keep things from flying out the back (it can also be arranged such that the load stopper is at a higher height by using the inner gateÂ’s stopper). The inner gate folds down perpendicular to the ground to allow closer access to the bed. A full-width step is available if you fold both “gates” down and pop out the inner panel. And lastly, the inner gate can be lowered to use it as a small work space. You can watch the short video above to get a quick run through of all the positions, or scroll through the gallery at the top of this post. Besides the tailgate, Chevy says the 2022 Silverado HD is gaining a new Greenstone Metallic exterior paint color. Other changes for 2022 were not detailed at this time, but Chevy says the trucks with this tailgate should be available sometime this summer. Related video:

2015 Chevy Tahoe gets Police Patrol Vehicle treatment

That was fast. Mere days after showing a Police Concept based on the 2015 Tahoe at the SEMA Show, Chevrolet has announced that it will build a PPV model based on the SUV to do battle with the Ford Police Interceptor Utility (Explorer) and Dodge Durango Special Service.
You'll recall that the Tahoe has been police staple for several years, predating both the Explorer and Durango police variants, so the fact that the new model would spawn a police variant is hardly surprising. Like the civilian model, the 2015 PPV benefits from a more efficient 5.3-liter, direct-injection V8 that pumps out 355 horsepower and 383 pound-feet of torque. It also features more high-strength steel, offering better crash protection, on top of optional safety items like lane departure warning, forward collision alert and a Safety Alert Seat.
The press release is rather light on police-specific items, aside from the auxiliary battery, which keeps the myriad of electronics in a modern police car running even when the engine isn't. Lightbars, 17-inch steel wheels on Goodyear Eagle RS-A tires and a push bar round out the mods for the Tahoe PPV. The cabin features a revised center console and room for laptop and other equipment mounts.
