Chevy Malibu will become 45-mpg strong hybrid with next update

Come next year there'll be no more mild hybrid pretensions for the Chevrolet Malibu - the next-generation sedan will borrow technology from the 2016 Volt and get a proper hybrid powertrain. A 1.8-liter four-cylinder engine gets help from a two-motor drive unit adapted from the Volt for 182 system horsepower, the motor drive powered by an 80-cell, 1.5-kWh lithium-ion battery. Chevrolet says that when combined with features like grille shutters and a lower ride height, it expects the Malibu Hybrid will post a combined fuel economy rating of more than 45 miles per gallon, which would best the hybrid trims of the Ford Fusion, Toyota Camry and Hyundai Sonata. Electric power alone can power the car up to 55 miles per hour, and The Bowtie's first use of exhaust gas heat recovery will help maintain high hybrid performance in cold weather and be used to heat the engine and cabin. The Malibu Hybrid should go on sale in the Spring of next year, for now there's a press release below. Chevrolet Malibu Hybrid Derives Technology from Volt GM estimates combined fuel economy ratings to exceed 45 mpg DETROIT, 2015-03-25 – Chevrolet's recent production announcement of its all-electric vehicle based on the Bolt EV concept, as well as the introduction of the 2016 Chevrolet Volt, will be joined by a strong hybrid version of the next-generation Malibu. Using technology from the 2016 Chevrolet Volt propulsion system, Malibu Hybrid will offer an estimated combined fuel economy rating exceeding 45 mpg, higher than the combined mileage ratings of the Ford Fusion, Toyota Camry and Hyundai Sonata hybrid variants. "The 2016 Malibu Hybrid will offer impressive fuel economy, exceptional driving characteristics and gorgeous styling," said Jesse Ortega, Chevrolet Malibu chief engineer. "Besides leveraging innovation from the Chevrolet Volt, the Malibu Hybrid also has unique features that help improve aerodynamics, like upper and lower grille air shutters to improve airflow and a reduced ride height, all of which help reduce fuel consumption," Ortega said. An all-new direct-injection 1.8L 4-cylinder engine mated to a two-motor drive unit slightly modified from the 2016 Chevrolet Volt drive unit powers the Malibu Hybrid. The drive unit provides additional power to assist the engine during acceleration, for 182 horsepower (136 kW) of total system power.

How GM engineers are using diaper 'snow' to keep you warm

Testing how snow affects General Motors' vehicles isn't really a problem right now for the company's engineers, but in the dog days of summer the process isn't exactly easy. The only real option is for them to book time at the automaker's climatic wind tunnel. However, a flash of brilliance from an engineer allows snow to be simulated regardless of the temperature outside, and the discovery is all because of his daughter's wet diaper. The realization came to GM Thermal Systems engineer Nicholas Jahn while he was swimming with his daughter and noticed how her diaper ballooned in size in the water. He found out the substance that makes this possible is called sodium polyacrylate. When the material gets wet it grows and forms fluffy flakes that are a close imitation of snow. Best of all, the stuff can be prepared easily any time of the year, and it's reusable. The engineering team uses the material to test the effectiveness of the heating systems of GM's vehicles. They spread the sodium polyacrylate over the inlets at the base of the windshield to obstruct the airflow and then crank the heater. After some time, they can see how much is being sucked into the system and design more efficient systems in the future. See how the process works in the video above and read about the diaper discovery in GM's press release below. Diapers Change Chevy Cruze Winter Warm-up Time GM validation engineer uses diaper material "snow" to reduce frigid drives 2015-01-06 DETROIT – An item commonly found on an infant's changing table is helping General Motors' engineers simulate snow year round, ensuring heating systems in cars like the 2015 Chevrolet Cruze can quickly and efficiently warm its interior. Packed snow can prevent air from entering the inlet panel at the bottom of the windshield, obstructing the flow of air into the heating system and reducing the amount of air it can push out. This can lead to less efficient warming of the car's interior and windshield defrosting. "The last thing anyone wants to do when it's freezing cold out is scrape their windshield," said Nicholas Jahn, GM Vehicle Thermal Systems engineer. "The testing we perform on the Chevrolet Cruze with the diaper material allows us to maximize the car's heating capabilities." Ironically, Jahn stumbled upon his diaper-based testing method in the middle of summer. During a swim with his daughter, he noticed her diaper multiplied in size when it came into contact with water.

GM tinkering with Silverado, Sierra model mix amidst strong early sales

Variety, as they say, is the spice of life. That's a lesson that is currently being taught to General Motors, because despite a strong showing from its 2014 Chevrolet Silverado and GMC Sierra, the General's pickup sales still can't best those of cross-town rival Ford.
With 59,163 trucks moved, GM fell just over 1,000 units short of toppling Ford, and one of the main reasons for that, according to GM's chief sales analyst, was due to a lack of variety in the engines and body styles available on dealer lots. "We are still over-weighted toward crew-cab V8 trucks. Our light-duty mix will moderate over time as our launch progresses," said Kurt McNeil.
Loading dealers with the popular combination of the 5.3-liter V8 and the four-door, Crew Cab body style was intentional during the truck's launch, but as supplies of leftover 2013 models, which are being sold at heavy incentives, are beginning to wane, both budget-conscious and high-dollar buyers are looking elsewhere instead of at the volume model pickups.
