Weekly Recap: Volvo buys Polestar, makes performance a priority

Volvo is taking its performance business in-house, and the Swedish carmaker announced Tuesday that it bought tuning company Polestar, which has long been known for producing sporty Volvos. The move allows Volvo to ramp up its performance business, and it plans to increase Polestar-branded vehicle sales to 1,000 to 1,500 annually, up from the 750 total projected for this year. The companies have been working together on motorsports projects since 1996. Financial terms of the sale were not released, and Polestar workers will move over to Volvo. Former Polestar owner Christian Dahl will keep control of the Polestar racing team and operate it under a new name. In addition to sales volume, Volvo has ambitious plans for other parts of Polestar, including its aftermarket business. Volvo also said it will use its twin-engine hybrid technology for Polestar models in the future, though specifics and timing were not revealed. Meanwhile, Volvo announced it will offer a run of 265 total Polestars in the United States for the 2016 model year, with S60 and V60s available. "Driving a Volvo Polestar is a special experience. We have decided to bring this experience to more Volvo drivers, placing the full resources of Volvo behind the development of Polestar as the model name for our high performance cars," Volvo CEO Hakan Samuelsson said in a statement. OTHER NEWS & NOTES 2016 Chevy Silverado, GMC Sierra, get nose jobs Automakers tend to refer to light updates as 'facelifts,' and that's exactly what Chevy gave the 2016 Silverado and GMC Sierra. Chevy slightly changed the front end of the truck. Using the one photo released of the new Z71 model as a guide, we can see that the headlights went from a stacked vertical design to single bulbs, and they are set on top of LED running lights. The grille has more body-colored elements instead of shiny metal, and the hood has a new line running down the middle (look really closely). The design theme will be similar across the portfolio, though materials and details will vary, a spokesman said. Some models, like the High Country and LTZ will have more chrome, and the LEDs are only for the upper trims. Chevy also said it will use the eight-speed automatic transmission on more versions of the Silverado, and it updated the MyLink feature to support Android Auto and Apple CarPlay.

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.

Some 2012-13 Chevy Volts may not have enough battery coolant

The 2012 and 2013 model year Chevrolet Volt extended-range plug-in vehicle may have a battery glitch caused by low coolant levels. No recall has been issued and General Motors is taking care of the issue at no cost to drivers. Some of the affected Volts may have lower-than-advisable coolant levels because of some pesky air pockets in the car's cooling circuit. When the coolant levels get too low, the charging system for the battery powering the car's onboard generator (i.e. the Rechargeable Energy Storage System, or the RESS) may be shut down, turning one's Volt into a run-of-the-mill gas-powered car, and a pricey one at that. The Car Connection says GM is advising owners of the '12 and '13 Volts to contact their local Chevy dealer for a free fix. GM representatives didn't immediately respond to a request for comment from AutoblogGreen for more details. We believe this is a separate issue than the one that brought 8,000 Volts back to the dealers for a battery coolant fix, what GM called a "voluntary customer satisfaction effort," a few years ago. General Motors sold 23,094 Chevy Volts last year after selling 23,461 Volts in 2012, so that fix-it list may get fairly lengthy. Check out a GM-Volt.com user thread related to this issue here. *UPDATE: Chevrolet spokesman Randy Fox confirmed in an e-mail to AutoblogGreen that the company issued a service bulletin to dealers that they may need to top off coolant levels on certain Volts because of the issue, and that the vehicle will "return to normal charging operation" once that's done.
