However, Kia's engineers are targeting a significant reduction in
CO2 tailpipe emissions and fuel consumption and a power increase of between 15 to 20 percent for any model which could be equipped with the new powertrain.
The study used the utility factor (since in pure EV mode there are no tailpipe emissions) and the EPA best estimate of
the CO2 tailpipe emissions produced by these vehicles in real world city and highway operation based on the EPA 5 - cycle label methodology, using a weighted 55 % city / 45 % highway driving.
However, Kia's engineers are targeting a significant reduction in
CO2 tailpipe emissions and a power increase of between 15 to 20 percent for any model which could be equipped with the new powertrain.
Most cars — even hybrids — release tons of
CO2 tailpipe emissions every year.The Nissan LEAF doesn't use a single drop of gas.
Not exact matches
Since carbon dioxide (
CO2) is the natural by - product of the combustion of fuel, the increased standards would also address climate change by reducing
tailpipe emissions of
CO2.
Mazda isn't hedging its bets on electric power just yet, believing that until the worldwide electrical grid is predominantly powered by renewable energy, an electric vehicle's
tailpipe emissions are too far offset by the dirtiness and high
CO2 values of the fossil - fuelled coal, oil, and gas power plants that supply their electricity.
As the need to reduce
emissions increased, more manufacturers sought to design their own hybrid systems and significant gains have been found in cutting harmful
tailpipe gases like
CO2 and NOx.
This ensures all performance parameters remain balanced and consistent * Offers a reduction in
CO2 emissions of up to 70 % (well - to - wheel), a measure of a fuel's net contribution to the atmosphere, not just
tailpipe emissions
Well - to - wheel is a measurement of a fuel's net
CO2 contribution to the atmosphere, not just
tailpipe emissions.
The charts also show a breakdown of total
emissions into
tailpipe emissions at point - of - use (
CO2: 2.15 tonnes, NOx + PMs: 6.3 kilograms), together with upstream
emissions generated during fuel and vehicle production.
Pioneered in the Supersports coupe, this FlexFuel technology offers a reduction of up to 70 per cent in
CO2 emissions on a well - to - wheel basis, a measure of a fuel's net contribution to the atmosphere, not just
tailpipe emissions.
«But legally defining it [
CO2] as a pollutant allows the EPA to e.g. use existing laws to regulate
tailpipe emissions.»
If Congress were to not only eliminate EPA's regulatory authority, but take
CO2 completely out of the Clean Air Act, it would still be up to the courts to decide whether or not that would eliminate state authority over vehicle
tailpipe emissions.
2011 (August) National Program Standards Phase I (Heavy Duty) Sets Medium and Heavy Duty Vehicles fuel efficiency and
tailpipe emissions standards estimated to reduce
CO2 emissions by about 270 million metric tons and save about 530 million barrels of oil over the life of the vehicles built in model years 2014 - 2018.
According to the
Tailpipe Rule,
CO2 emissions due to air conditioner - related loads on automobile engines account for 3.9 % of total passenger car greenhouse gas
emissions, and various technologies could reduce air conditioner - related
CO2 emissions by 10 % to 30 %.51 A 30 % reduction of the 3.9 % of motor vehicle
emissions associated with air conditioner engine load would decrease fuel consumption by only 1.1 %.
These produce more than a third of global
CO2 emissions but it is impractical to capture the gas at source from
tailpipes or flues.
As EPA's
Tailpipe Rule acknowledges (p. 25327), there is a «single pool of technologies... that reduce fuel consumption and thereby reduce
CO2 emissions as well.»
Also, I had read somewhere in this set of websites or their relatives (don't remember where now), that 22 mpg was average, and the «greenhouse gas calculator» implies the average car's
tailpipe emission is 400 g
CO2 / mi (see below / later).
Volkswagen introduced a turbo - diesel hybrid - electric Golf concept car at the Geneva Motor Show, and the specs were impressive: 70 miles per gallon (3.3 liters per 100 kilometers), a 7 - speed direct shift gearbox (DSG) with a twin - clutch, minor modifications to reduce aerodynamic drag,
CO2 emissions of 89 g / km (lower than a Toyota Prius hybrid), and Tier 2 Bin 5
tailpipe emissions.
When compared with the standard hybrid, the plug - in hybrid at 68 miles per gallon (MPG), achieved a 58 - percent increase in gas mileage, a 37 - percent decrease in carbon dioxide (
CO2)
tailpipe emissions, and a 10 - percent reduction in fuel costs.
