Naravno, realno koliko i svaciji fabricki podaci o potrosnjiMilos_kg napisao:Jesu li ove potrosnje realne?
Grad ~5l, na otvorenom ~3.5, prosek ~4
A onda dodas 50% i dobijes nesto sto ces mozda nekada imati, ako pricamo o gradskoj voznji, koja je, ako se dobro secam, propisana na do 19 km/h
Evo i zasto veze sa zivotom ti podaci nemaju:
In the European Union, passenger vehicles are commonly tested using two drive cycles, and corresponding fuel economies are reported as 'urban' and 'extra-urban', in litres per 100 km and (in the UK) in miles per imperial gallon.
The urban economy is measured using the test cycle known as ECE-15, first introduced in 1970 by EC Directive 70/220/EWG and finalized by EEC Directive 90/C81/01 in 1999. It simulates a 4,052 m (2.518 mile) urban trip at an average speed of 18.7 km/h (11.6 mph) and at a maximum speed of 50 km/h (31 mph).
The extra-urban driving cycle or EUDC lasts 400 seconds (6 minutes 40 seconds) at an average speed 62.6 km/h (39 mph) and a top speed of 120 km/h (74.6 mph).[40]
EU fuel consumption numbers are often considerably lower than corresponding US EPA test results for the same vehicle. For example, the 2011 Honda CR-Z with a six-speed manual transmission is rated 6.1/4.4 L/100 km in Europe[41] and 7.6/6.4 L/100 km (31/37 mpg ) in the United States.[42]
In the European Union advertising has to show Carbon dioxide (CO2)-emission and fuel consumption data in a clear way as described in the UK Statutory Instrument 2004 No 1661.[43] Since September 2005 a colour-coded "Green Rating" sticker has been available in the UK, which rates fuel economy by CO2 emissions: A: <= 100 g/km, B: 100–120, C: 121–150, D: 151–165, E: 166–185, F: 186–225, and G: 226+. Depending on the type of fuel used, for gasoline A corresponds to about 4.1 L/100 km (69 mpg-imp; 57 mpg-US) and G about 9.5 L/100 km (30 mpg-imp; 25 mpg-US).[44] Ireland has a very similar label, but the ranges are slightly different, with A: <= 120 g/km, B: 121–140, C: 141–155, D: 156–170, E: 171–190, F: 191–225, and G: 226+.[45]
In the UK the ASA (Advertising standards agency) have claimed that fuel consumption figures are misleading. Often the case with European vehicles as the MPG (miles per gallon) figures that can be advertised are often not the same as 'real world' driving.
The ASA have said that Car manufacturers can use ‘cheats’ to prepare their vehicles for their compulsory fuel efficiency and emissions tests in a way set out to make themselves look as ‘clean’ as possible. This practice is common in petrol and diesel vehicle tests, but hybrid and electric vehicles are not immune as manufacturers apply these techniques to fuel efficiency.
Car experts[who?] also assert that the official MPG figures given by manufacturers do not represent the true MPG values from real-world driving.[46] Websites have been set up to show the real-world MPG figures, based on crowd-sourced data from real users, vs the official MPG figures.[47]
The major loopholes in the current EU tests allow car manufacturers a number of ‘cheats’ to improve results. Car manufacturers can:
Disconnect the alternator, thus no energy is used to recharge the battery;
Use special lubricants that are not used in production cars, in order to reduce friction;
Turn off all electrical gadgets i.e. Air Con/Radio;
Adjust brakes or even disconnect them to reduce friction;
Tape up cracks between body panels and windows to reduce air resistance;
Remove Wing mirrors.[48]
According to the results of a 2014 study by the International Council on Clean Transportation (ICCT), the gap between official and real-world fuel-economy figures in Europe has risen to about 38% in 2013 from 10% in 2001. The analysis found that for private cars, the difference between on-road and official CO2 values rose from around 8% in 2001 to 31% in 2013, and 45% for company cars in 2013. The report is based on data from more than half a million private and company vehicles across Europe. The analysis was prepared by the ICCT together with the Netherlands Organisation for Applied Scientific Research (TNO), and the German Institut für Energie- und Umweltforschung Heidelberg (IFEU).[49]
