Ever since a famous car manufacturing company has been caught cheating on emission testing and fuel consumption figures, consumers have been quite wary of buying new cars. Starting at this time, consumers are not too quick to believe laboratory testing released by car manufacturers and dealers.

AutoExpress UK reports that there is now a wide availability of "Real-world testing" that could help car buyers in understanding how much fuel consumption and CO2 emissions the vehicle actually has.Set to be released in 2017, the Worldwide Harmonized Light Vehicles Test procedure or WLTP will be hitting stores and would be a helpful device for all car buyers.  

This particular test is the first on-the-road procedure that will measure actual figures from the vehicle as it drives. It will be a device which is strapped to the back of the car. There are tubes connected from the exhaust leading to the flow meter of the device, to measure Nitrogen Oxide and Carbon dioxide. Exhaust will be analyzed and then data will be released. The WLTP are to be available by September of 2017.

According to a report from FleetPoint, only a small percentage of 10% average on the MPG the vehicle originally advertised. This means that a good majority of all vehicles in the world have not bridged the gap between their on-the-road MPG and advertised MPG. This means that a number of cars have used fuel efficiency as their selling point and if these figures are true, it is a scandalous scam.

Other than the fact that the fuel efficiency is a major selling point, there are now government fines for vehicles that release a significant amount of CO2 into the environment. In the UK alone, a benchmark of 130g/km is the limit. This limit may be among the reasons why car manufacturers opt to "optimize" laboratory tests and lead to quite unrealistic results.
