Camaro chief: 'rock-star' 4-cylinder set for Mustang fight

It was inevitable, the 2016 Chevy Camaro had to have a four-cylinder engine. The archrival Ford Mustang packs a spunky 2.3-liter EcoBoost four-banger, and everyone from BMW to Subaru uses four-cylinders to great effect to power their sports cars. Now it's Chevy's turn. Again. The Camaro ran the infamous Iron Duke four-cylinder with 88 to 92 horsepower in the 1980s. It was a fuel-economy play at a time when performance was not a priority. After the 1970s muscle-car era, output even for the V8s didn't top 200 hp again until the mid-'80s. Thankfully for enthusiasts, things have changed dramatically in the last 30 years. The gen six Camaro will offer a 2.0-liter inline four-cylinder with 275 horsepower. It's the standard engine, slotting below the 335-hp V6 and the 455-hp V8. But don't mistake the new I4 for an Iron Duke encore. Camaro chief engineer Al Oppenheiser called it a "rock star" and said cars equipped with it feel lighter than V6 models. The four-cylinder (295 pound-feet at 3,000-4,500 rpm) also summons more torque in quicker fashion than the V6 (284 lb-ft at 5,300 rpm). Chevy expects the Camaro to hit 60 miles per hour in "well under six seconds," according to press materials. The Mustang EcoBoost (310 hp, 320 lb-ft) clocks times in the low to mid five-second range. "We're not doing it just so we have one," Oppenheiser said. "We're not doing it because like in gen three you're forced to do it because of fuel economy. We're doing it because it belongs in the car. It has a distinct character." Speaking with Autoblog recently at the Detroit Grand Prix racecourse on Belle Isle, Oppenheiser said he expects the I4 to attract a younger crowd to the Camaro and will put up stiff competition against the V6 for sales. "I've read blogs where younger folks won't buy a Camaro because it doesn't have a 2.0-liter turbo or a turbocharged four-cylinder," he said. "So we're going to excite them." While we talked a lot about four-cylinder engines, Oppenheiser also elaborated on the V6 (It's pretty damn good, too. We drove it.) and the new Alpha platform that the Camaro borrowed from Cadillac. Here's the rest of our edited conversation. Autoblog: Talk a little bit about the four-cylinder – the first turbo four-cylinder ever for Camaro. Do you have any idea what the take rate's going to be? Al Oppenheiser: I think it's going to surprise a lot of people. It's actually a fun car to drive. It's got a really good balance of turbo noise and exhaust note.

Chevy Bolt EV's battery shows big improvements over Spark's

Plug-in vehicle battery technology moves fast, and all you need to do to see this in action is to take a look at the new 60-kWh lithium-ion pack inside the 2017 Chevy Bolt EV. Well, you need to do that and then compare it to the battery packs inside of GM's other plug-in vehicles. And you don't even to go as far back as the EV1 to see progress. Let's start with what we know about the new Bolt's pack. It is supposed to drive the Bolt EV over 200 miles on a full charge. It weighs 960 pounds and is made up of 288 cells. Chevy's other all-electric car, the limited-availability Spark EV, had a 19-kWh pack and offered 82 miles of range. It had 192 cells and weighed 474 pounds. So, in the few years since the Spark EV was released, GM engineers have figured out how to get three times the energy capacity and almost two-and-a-half times more range out of a pack that weighs only about twice as much. And that doesn't even get to the price drops. GM has figured out how to get 3x the energy capacity and almost 2.5 times more range out of a pack that weighs only twice as much. Speaking of those 288 cells, that number might sound familiar to regular readers because that's exactly how many are in the new Chevy Volt. But the packs in the Volt and the Bolt are entirely different beasts. For one thing, while the Volt cells are made by LG Chem in Holland, MI, LG Chem will make the Bolt's cells in South Korea. The cell chemistries are also different. We spoke with GM engineer Tim Grewe (again) and while he declined to answer some of our Bolt battery pack questions until more details are unveiled at the SAE World Congress in April, he was able to explain a few things. "The cell inside the Chevy Bolt EV was specifically designed for EV range so it's up on energy," he said. "That's a different cell chemistry than on the extended range Chevy Volt, which is a smaller pack, smaller energy but more power per cell. We work with all of those vehicle requirements and customer demands and we say how do we meet this and we change the chemistry to make it all work." Comparing the 60 kWh in the Bolt and the 18.4-kWh pack in the Volt is really one of those apples to oranges issues, he said. "If you look at the Volt battery pack, how it went from where it was and where it's up to, from 38 miles to 50 miles, that was basic, overall industry improvement. Now, the 18 [kWh] to the 60 [kWh] is extended range vs. EV.

New Takata problem results in recall of 414 GM vehicles

An airbag-inflator rupture discovered by Takata during testing has resulted in a new recall affecting 414 vehicles from General Motors, including 395 of them in the US. This latest campaign covers 2015 model-year examples of the Buick LaCrosse, Cadillac XTS, Chevrolet Camaro, Equinox, Malibu, and GMC Terrain. There are no reported breaks in any of these vehicles on the road, and the company estimates only one percent of them actually have the faulty parts. According to documents submitted to the National Highway Traffic Safety Administration (as a PDF), one side-airbag inflator failed a cold test at -40 Fahrenheit "releasing high pressure gas and propelling the separated components apart." The supplier told GM about the failure the next day. In these vehicles, the safety device might not only burst but the bag could inflate incorrectly, as well. GM and Takata say that a cause is not yet known, but they are "conducting an investigation." GM will begin notifying affected owners via overnight mail on Oct. 19. Dealers will replace the side airbag modules on all of the affected vehicles with new components outside of the suspect lot. All of the removed parts will also be collected for further study. Takata's faulty front airbag inflators have resulted in a serious scandal for the supplier. Initial figures indicated 34 million US vehicles are need of repair, though more recent figures have knocked that down to 23.4 million bad parts in 19.2 million automobiles. GM was already among the dozen automakers with models to fix, and some of its pickups were affected, along with the Saab 9-2X and Pontiac Vibe. GM Statement: General Motors is recalling 395 cars and crossovers in the U.S. because one of the front seat side air bags inflators may be defective. In the event of a deployment, the air bag's inflator may rupture and the air bag may not properly inflate. The rupture could cause metal fragments to strike the vehicle occupants, potentially resulting in serious injury or death. GM is unaware of any incidents involving vehicles with these components, which were part of a lot in which one inflator failed acceptance testing at the supplier. Dealers will replace the side air bag module or modules in affected vehicles. Including Canada, Mexico and exports, the total population of the recall is 414, GM estimates 1 percent of the recalled vehicles may have the defect.
