HyBoost concept achieving close to Prius-level CO2 emissions; aggressive downsizing with advanced boosting and micro-hybrid system

Green Car Congress

HyBoost achieves this by combining aggressive 50% downsizing of the engine with an electric supercharger for transient low-speed performance, and a micro-hybrid stop-start and energy recuperation systems, Boggs said.

Study finds technology cost of achieving European 2020 LDV CO2 targets more than offset by resultant fuel savings

Green Car Congress

A report published by Cambridge Econometrics and Ricardo-AEA concludes that overall, the cost of technologies required to meet proposed European 2020 CO 2 regulations for vehicles (95 g/km for cars and 147 g/km for vans) will be more than offset by the resultant fuel savings.

ICCT: decline in diesel sales will have negligible impact on attainment of European CO2 emission standards

Green Car Congress

The ICCT projects that a decline in diesel shares down to 15% in 2025 would not interfere with meeting EU CO 2 standards and would actually decrease costs of meeting CO 2 standards.17. VW Golf) market segments are, on average, similarly priced (±1%), but hybrid electric vehicles have approximately 20% lower CO 2 emissions.

Ricardo: achieving light-duty diesel RDE NOx compliance in urban driving is possible, at a price

Green Car Congress

Future RDE emissions legislation and fleet average CO 2 targets represent a challenge for automakers wishing to provide cost-effective light duty diesel vehicles. Solutions were also tested on an engine dyno, providing steady-state test results to help understand the mechanisms involved, and provide input data for the simulation.

National Research Council Study Finds That Available Technologies Can Result in Significant Fuel Savings for Passenger Vehicles Over the Next 15 Years, But at Higher Purchase Prices for Consumers

Green Car Congress

Among the findings were: Adopting the full combination of improved technologies in medium and large cars and pickup trucks with spark-ignition engines could reduce fuel consumption by 29% at an additional cost of $2,200 to the consumer. For example, the report notes the promise of cylinder deactivation, turbocharging and downsizing.

Survey finds big shift in UK buyers’ attitude to diesel; more concern over running costs than environment

Green Car Congress

More than 84% of car buyers surveyed are also worried about possible legislation changes that may affect the cost of ownership of diesel cars in the future, such as the retail price, fuel duty and vehicle road tax. There appears to have been a dramatic shift in the petrol and diesel sales seesaw.

OEMs shifting towards onboard chargers > 6 kW for EVs; lower output chargers to remain dominant through 2020

Green Car Congress

All suppliers are working on downsizing the charger by 10% to 15% by decreasing its weight and volume and increasing the power density. Suppliers must, however, begin to manufacture DC-DC converters and PFCs themselves, as these components account for the maximum cost of onboard chargers and contribute to higher prices.
