MotorWeek Retro Review revisits 1984 Corvette

MotorWeek's Retro Reviews are always a great glimpse into the cars of yesteryear. However, the newly uploaded look back at the 1984 Chevrolet Corvette is an absolute treasure trove for any auto history buff. This is a full episode of the show from the '80s, and it's dedicated to all of the details about the newest 'Vette to hit the market at the time. Beyond just the usual drive and an in-depth walk around, one of the major highlights here is a brief look at some on the concepts that eventually resulted in the fourth-generation Corvette of 1984. The C4's shape harkens back to sketches from 1978, and there even shots of early clay models that led the way for the design. MotorWeek also takes a tour through the Bowling Green, KY, factory for a detailed inspection of the entire production process. John Davis repeatedly calls the Corvette "the plastic fantastic" during the episode, and he can't find too much negative to say about being behind the wheel of the then-new coupe. See how it stands up to your own memories in the clip above.

GM Ultium tech can scavenge heat from everywhere, even you

GM likes to give us tidbits about its Ultium platform from time to time, and today it’s telling us about the platformÂ’s ability to capture waste heat from the propulsion system. In addition to capturing from the propulsion system, it can also capture humidity from both inside and outside the vehicle and even from passengersÂ’ body heat. Yes, you, your family and/or your friends are a usable heat source as far as GM EVs are concerned. It then deploys the heat in an advantageous way. If at this point, youÂ’re screaming, "Heat pump!" youÂ’d be right. WeÂ’re talking about an elaborate heat pump system that GM is using for its Ultium-based vehicles. Every Ultium-based GM vehicle gets this system that is covered by 11 patents and four publications. The waste heat it collects is used in a number of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims it can heat the cabin of its Ultium-based vehicles quicker than vehicles with traditional internal combustion engines. Plus, when put to use, GM claims that using the heat pump provides its EVs with up to 10% more range than theyÂ’d have without. Beyond heating the cabin, the heat pump is capable of putting waste heat to use by preheating the battery prior to charging so that you can charge quicker. The system can even cool the propulsion system in preparation for Watts to Freedom (WTF) launch control starts. GM says this was vital in helping the Hummer EV achieve its bonkers 0-60 mph time of about 3 seconds. “Having a ground-up EV architecture gives us the freedom to build in standard features like UltiumÂ’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chain. “This helps us squeeze more efficiency, performance and overall customer benefit out of our EVs.” GM says itÂ’s been developing heat pump technology since the EV1 and its heat pump. This is the modern evolution of that technology, and GM says itÂ’s going to be implemented in every Ultium-based vehicle as a standard feature.

GM to cut production at 5 plants in North America, kill several models

DETROIT/WASHINGTON — General Motors Co said on Monday it will cut production of slow-selling models and slash its North American workforce in the face of a stagnant market for traditional gas-powered sedans, shifting more investment to electric and autonomous vehicles. The announcement is the biggest restructuring in North America for the U.S. No. 1 carmaker since its bankruptcy a decade ago. GM said it will take pre-tax charges of $3 billion to $3.8 billion to pay for the cutbacks, but expects the actions to improve annual free cash flow by $6 billion by the end of 2020. GM plans to halt production next year at three assembly plants: Lordstown, Ohio, Hamtramck, Michigan, and Oshawa, Ontario. The company also plans to stop building several models now assembled at those plants, including the Chevrolet Cruze, the Cadillac CT6 and the Buick LaCrosse, the sources said. Sources said the Chevrolet Volt, Impala and Cadillac XTS would also be discontinued. Signs of the demise of six passenger-car models have been swirling since July. Plants in Baltimore, Maryland, and Warren, Michigan, that assemble powertrain components have no products assigned to them after 2019 and thus are at risk of closure, the company said. It will also close two factories outside North America, but did not identify those plants. The AP reported that 14,700 jobs would be affected. Some 8,100 of those would be white-collar jobs reduced through buyouts or layoffs. The No. 1 U.S. automaker signaled the latest belt-tightening in late October when it offered buyouts to 50,000 salaried employees in North America. The company also said it will cut executive ranks by 25 per cent to "streamline decision making." Some 6,000 factory workers could lose their jobs or be transferred to other plants. Its shares were last up 6.2 percent at $38.16. Tariff 'headwinds' and cost-cutting GM Chief Executive Officer Mary Barra told reporters on Monday the company can reduce annual capital spending by $1.5 billion and increase investment in electric and autonomous vehicles and connected vehicle technology because it has largely completed investing in new generations of trucks and sport utility vehicles. Some 75 percent of its global sales will come from just five vehicle architectures by early in the 2020s. It plans to reduce annual capital spending to $7 billion by 2020 from an average of $8.5 billion a year during the 2017-2019 period.
