2016 Chevy Malibu Hybrid, now with 48 mpg city

The 2016 Chevrolet Malibu is already one of the stars of the 2015 New York Auto Show thanks to a huge improvement in styling, lighter weight and new suite of tech. Now, Chevy is shifting the focus to the available hybrid model and detailing some more of its impressive figures. The 2016 Malibu Hybrid's powertrain consists of a 1.8-liter four-cylinder and a two-motor hybrid system with a 1.5-kilowatt hour lithium ion battery. Chevy's engineers are aiming for EPA fuel economy ratings of 48 miles per gallon city, 45 mpg highway and 47 mpg combined. The setup puts out a total of 182 horsepower, and it can accelerate the sedan to 60 miles per hour in a claimed 7.8 seconds. Also, speeds of up to 55 miles per hour can even be reached under fully electric power. Some of this efficient tech is shared with the latest Volt, including the regenerative braking. For reference, the 2015 Ford Fusion Hybrid carries an EPA rating of 44 mpg city, 41 mpg highway and 42 mpg combined, and its hybrid system puts out a total of 188 hp. There is a wait ahead for buyers looking to park the 2016 Malibu Hybrid in their garage, though. While the standard model should be on sale before the end of the year, the hybrid doesn't arrive in showrooms until the spring of 2016. Malibu Hybrid Estimated to Reach 48 MPG in City Driving New sedan projected to offer segment unsurpassed 47 MPG combined 2015-04-01 NEW YORK –The 2016 Chevrolet Malibu Hybrid, which uses technology from the Chevrolet Volt, will offer a General Motors-estimated 48 mpg city, 45 mpg highway – and 47 mpg combined, unsurpassed in the segment, GM President Dan Ammann announced today. Ammann made the announcement at an International Motoring Press Association breakfast before the 2016 Malibu was to be unveiled at the New York International Auto Show. "Fuel efficiency is important to our customers, especially in the midsize segment and with an estimated 48 mpg city rating, the Malibu Hybrid delivers," Ammann 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. An 80-cell, 1.5 kWh lithium-ion battery pack provides electric power to the Hybrid system. The advanced lithium-ion based chemistry can power the Malibu hybrid at up to 55 miles per hour on electricity alone.

The tricky business of octane, power, and MPG

Given tepid green-car sales numbers this year, consumers in the US aren't making the transition away from internal combustion engines too quickly. Regulations are still mandating cleaner emissions, though. In addition to downsizing and turbocharging, there's growing consideration about moving to higher-octane fuel to improve overall efficiency. In a new report, engineers at FCA, Ford and General Motors Powertrain are showing that it could work, too. The major advantage to higher-octane fuel is that it supports higher compression ratios. That in turn can lead to more power from burning the same amount of gas. "Higher ethanol content is one available option for increasing the octane ratings of gasoline and would provide additional engine efficiency benefits for part and full load operation," the researchers write in the study's abstract. The authors even think it could be possible to update some modern vehicles' engine calibration to be optimized for the better gas. While the benefits are there, we still have a long way to go before higher-octane fuel becomes a national standard. According to Green Car Congress, 87 percent of the gas sold in the US is regular grade 87-octane. Meanwhile, premium 91-93 octane makes up just 10 percent. The various grades of fuel illuminate even more annoyances with the current system. For example, Ford generally recommends 93-octane for EcoBoost engines, and the power outputs that the company publishes are based on using it. However according to Green Car Reports, such premium gas is very difficult to find in some regions of the US, especially along the West Coast. The powertrains still run on lesser grades but with lower power output. The researchers' discussion of possibly increasing ethanol in gas also comes during a heated debate on the substance. The current administration is pushing for less of the corn-based fuel in the coming years. Although, several presidential hopefuls might be favor of reversing that course.
