T&E concludes that diesel cars emit more CO2 on a full lifecycle basis than gasoline cars

Green Car Congress

tonnes more CO 2 than an equivalent gasoline car over its lifetime due to a more energy-intensive refining of the diesel fuel; more materials required in the production of heavier and more complex engines; higher emissions from biodiesel blended in the diesel fuel; and longer mileage because fuel is cheaper. mpg US) and 7.1

EPA trends report sees record levels of average new vehicle fuel economy and CO2 emissions for MY 2012; role of new gasoline vehicle technologies

Green Car Congress

EPA projects advanced transmissions (6+ speeds and CVTs), gasoline direct injection (GDI) systems, and turbocharged engines will be installed on at least 15% of all MY 2013 vehicles. The majority of the emissions and fuel savings from current vehicles, EPA noted, is due to new gasoline vehicle technologies. mpg, or 22%.

mpg increase over the previous year and an increase of nearly 5 mpg since 2004. Fuel economy has now increased in eight of the last nine years; average carbon dioxide emissions are also at a record low of 369 g/mile in model year 2013. Since 1975, half of car production has consistently been within several mpg of each other.

EPA annual report on CO2, fuel economy and technology trends finds 2012 heading for all-time best; rapid adoption of new technologies

Green Car Congress

The US Environmental Protection Agency (EPA) released its annual report summarizing key trends in carbon dioxide emissions, fuel economy, and CO 2 - and fuel economy-related technology for gasoline- and diesel-fueled personal vehicles sold in the United States, from model years (MY) 1975 through 2012.

U Toronto team assess the climate trade-off between reduced CO2 and increased Black Carbon from GDI engines

Green Car Congress

The upside of gasoline direct injection (GDI) engines is widely seen as being improved fuel economy coupled with an increase in specific power (especially with turbocharging), enabling significant downsizing. The authors also explored the trade-offs between the fuel penalty of using a gasoline particulate filter and BC reduction efficiency.

Full lifecycle CO2 of new Mercedes C-Class 10% less than outgoing model

Green Car Congress

Over the entire lifecycle of the C 180, the lifecycle analysis yields a primary energy consumption of 521 gigajoules (corresponding to the energy content of around 16,000 liters of gasoline); an environmental input of approx. l/100 km (31 mpg US and 31.8 mpg) at the time of the market launch in 2007 or from between 6.4

Mercedes-Benz C 350 e PHEV can reduce full lifecycle CO2 emissions up to 41% compared to gasoline-engined C 250

Green Car Congress

Compared to the gasoline-engined C 250, the Mercedes-Benz C 350 e plug-in hybrid ( earlier post ) can reduce full life-cycle (manufacture, use over 200,000 km and recycling) CO 2 emissions by some 26% (9.6 liters per 100 kilometres (98 - 112 mpg US), or 55 – 48 g CO 2 /km) and up to 31 kilometres (19 miles) of all-electric driving.
