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.

Impala SS vs. Marauder: Recalling Detroit’s muscle sedans 

Impala SS vs. Marauder — it was comparo that only really happened in theory. ChevyÂ’s muscle sedan ran from 1994-96, while MercuryÂ’s answer arrived in 2003 and only lasted until 2004. TheyÂ’re linked inextricably, as there were few options for powerful American sedans during that milquetoast period for enthusiasts. The debate was reignited recently among Autoblog editors when a pristine 1996 Chevy Impala SS with just 2,173 miles on the odometer hit the market on Bring a Trailer. Most of the staff favored the Impala for its sinister looks and said that it lived up to its billing as a legit muscle car. Nearly two-thirds of you agree. We ran an unscientific Twitter poll that generated 851 votes, 63.9 percent of which backed the Impala. Muscle sedans, take your pick: — Greg Migliore (@GregMigliore) April 14, 2020 Then and now enthusiasts felt the Impala was a more complete execution with guts. The Marauder, despite coming along later, felt more hacked together, according to prevailing sentiments. Why? On purpose and on paper theyÂ’re similar. The ImpalaÂ’s 5.7-liter LT1 V8 making 260 horsepower and 330 pound-feet of torque was impressive for a two-ton sedan in the mid-Â’90s. The Marauder was actually more powerful — its 4.6-liter V8 was rated at 302 hp and 318 lb-ft. The ImpalaÂ’s engine was also used in the C4 Corvette. The MarauderÂ’s mill was shared with the Mustang Mach 1. You can see why they resonated so deeply with Boomers longing for a bygone era and also captured the attention of coming-of-age Gen Xers. Car and DriverÂ’s staff gave the Marauder a lukewarm review back in ‘03, citing its solid handling and features, yet knocking the sedan for being slow off the line. In a Hemmings article appropriately called “Autopsy” from 2004, the ImpalaÂ’s stronger low-end torque and smooth shifting transmission earned praise, separating it from the more sluggish Mercury. All of this was captured in the carsÂ’ acceleration times, highlighting metrically the differences in their character. The Impala hit 60 miles per hour in 6.5 seconds, while the Marauder was a half-second slower, according to C/D testing. Other sites have them closer together, which reinforces the premise it really was the little things that separated these muscle cars. Both made the most of their genetics, riding on ancient platforms (FordÂ’s Panther and General MotorsÂ’ B-body) that preceded these cars by decades. Both had iconic names.

1983 Motorweek showdown pits Porsche 928S vs. Chevy Camaro Z28

Last month, Motor Trend threw the Camaro Z/28 and Porsche 911 GT3 into the bear pit and let them fight it out. Way back in 1983, MotorWeek had the same idea, comparing the Camaro Z/28 to the Porsche 928S. At the time, the Camaro was America's best selling sports coupe, the 928S was Porsche's top-of-the-line model that also had the highest top speed of any car sold here. And the price differential was even more stark then: $13,600 for the Camaro, $45,000 for the Porsche. That put the Z/28's cast-iron, 5.0-liter V8 with 190 horsepower and 240 pound-feet of torque against the all-aluminum 4.7-liter V8 with 234 hp and 263 lb-ft in the 928S. Even with that and the Camaro being 14 inches longer than the Porsche, the American was a surprising 40 pounds lighter than the German. The show took them to Summit Point Raceway in West Virginia to see how close a relative performance bargain could hang with a the German GT. Both had five-speed manual transmissions, but the high-speed corners and tight sections of Summit Point would test other handling variables, including the "bone-rattling" Camaro's solid rear axle and disc and drum brake setup vis-a-vis the four-wheel disc brakes and independent suspension on the "firm-but-smooth" Porsche. Paradoxically, the larger disparity 22 years ago resulted in a closer result. Check out the video to see how the Summit was won.
