New emissions test may lead to 35% rise in taxes

Company car drivers and their employers face a potential tax bombshell if a new vehicle emissions test is introduced from 2017.

The new testing regime would provide a more realistic picture of fuel consumption, which the New European Driving Cycle (NEDC) has failed to deliver.

But fuel efficiency figures that better reflect real-world driving conditions will also result in an increase in the reported CO2 emissions.

Experts predict that the increase could be significant, with some suggesting that the reported emissions for a car could be up to 30% higher under the new regime.

Existing models would not be retested; the new test would apply only to new models. But company car drivers and employers, who pay tax according to a vehicle’s CO2 emissions, would be left facing a stark choice when it came to choosing a new vehicle.

An equivalent model tested under the proposed Worldwide Harmonised Light-duty Test Procedures (WLTP) could see their tax liabilities rocket by up to 35% (see panel, below).

It would effectively create a two-tier tax regime, with employers paying significantly more in Class 1A NIC and VED, and employees forced into a much higher benefit-in-kind tax bracket for choosing the latest variant of a car they had driven for the past three or four years.

It would leave them having to find the extra cash, consider downsizing or choosing an alternatively-fuelled vehicle. It could even persuade employers to ditch company car provision altogether and opt for a cash equivalent. In fact, 64.4% of fleets would forgo real-world figures if it meant they had to pay more in tax, according to a Fleet News poll.    

HM Treasury and HM Revenue and Customs told Fleet News that they had already announced the rates and bands for taxing a company car up to 2018/19 in order to provide tax certainty for car manufacturers, employers and employees.

A spokesman added: “The Government keeps all areas of tax legislation under review, but there are currently no plans to change the underlying structure of car tax legislation.”  

However, failure to address the issue could have a major impact on the car industry, with manufacturers producing new cars not wanted by fleets because their CO2 emissions are too high.

Plans for a new vehicle testing regime were first revealed by Fleet News in May, 2011, before the United Nations Economics Commission for Europe (UNECE) unveiled detailed proposals a year later.

Several aspects of the current NEDC test have been contributing towards a growing gap between official figures and real-world experience.

The procedure doesn’t adequately represent modern-day driving patterns and vehicle performance. The test car briefly reaches motorway speed so ‘highway’ driving is barely represented (see panel below). Air-conditioning, lights and other electrical loads – which increase fuel consumption – are all switched off for the test.

Flexibilities and tolerances in the test procedure can also be exploited to achieve a lower overall fuel consumption figure – speed that is within the specified corridor for the test, but consistently just below the target speed will result in lower fuel consumption than a speed that is just above.

In addition, the inertia load applied to the rolling road to simulate real-world vehicle inertia and aerodynamic drag can be varied only in subtle steps. 

A small reduction in vehicle weight, such as removing the standard spare wheel, may be enough to get the car just into the next lowest inertia load band and hence experience lower loads in the test than on the road in the real world. 

International Council on Clean Transportation (ICCT) research shows that a car is five times more likely to be just under an inertia limit than just over.

Stop-start systems will also show a relatively high benefit in a test in which idling is over-represented. The car is stationary for about 10% of the NEDC.

The Society of Motor Manufacturers and Traders (SMMT) has acknowledged the current testing regime’s failings, with its previous chief executive Paul Everitt admitting that figures were based on “an average, of an average of the worst possible average”.

UNECE gave the green light to the WLTP in March. It said: “WLTP better simulates real driving conditions, with more modern and realistic driving scenarios and considers other widely used factors such as air conditioning and seat heaters that drive fuel consumption upwards.

“It also closes many of the loopholes that existed in the current test method in order to create accurate, consistent and repeatable results on fuel consumption which are thus more difficult to manipulate.”

As a result, it estimates that the figures of the fuel consumption under the WLTP would be 10% to 20% higher than those under the current test cycle. The ICCT suggests it could be up to 30% higher.

The EU says it wants to replace the NEDC test with the much more stringent procedure by 2017, but the car industry is opposed to such a swift adoption.

A report in the Financial Times suggests that the European Automobile Manufacturers’ Association (ACEA) is lobbying for a 2021 implementation date at the earliest.

Erik Jonnaert, the group’s secretary-general, said: “Looking at the scale of the task required, ACEA believes 2017 is incredibly ambitious.”

It could also prove costly for carmakers. The EU has set a pan-European sales weighted average new car CO2 emissions target of 95g/km by 2020. Those manufacturers missing the target face penalties of up to €95 per g/km of CO2 over target per car registered. 

ACEA also recognises the potential problems WLTP could pose for CO2-based taxes.

It said: “Managing the change to the WLTP must be addressed. This includes the labelling of vehicles, how to deal with old test cycle and WLTP CO2 and fuel consumption test figures without confusing customers, how to apply the WLTP for the purpose of the legal monitoring against a future CO2 fleet average figure, and how governments will ensure that any CO2-based taxation scheme fairly addresses vehicles between the periods when the old test cycle is phased-out and WLTP is brought in.”

    So the trade finally admits that official fuel consumption figures are fictitious across the board. No surprise there!! But equally all CO2 emission figures are equally fictitious so customers have been misled by suppliers - maybe they will have to pick up the excess tax bills in future for misleading consumers. Chances of this happening .... zero. As we find with banks the bigger the organisation the more fraudulent behaviour goes unpunished. The consumer picks up the bill and the execs keep their yachts and huge lifestyles!!

      @Dave S - Official fuel consumption and CO2 figures are NOT fictitious, but it is well known that the test regime that all manufacturers must follow by law is not representative of real world driving, that is NOT the fault of the vehicle manufacturers. One of the largest variables for real world MPG and therefore CO2 is the driver, so which figures would you prefer were used, your own MPG or the higher/lower MPG of another driver in the same car? Hardly a practical solution, or more accurate than the current testing regime. To have any validity at all there has to be a standardised test, which by definition is unlikely to reflect real world driving, which is not standardised. The recent general trend for MPG is up and for CO2 is down, what you'd expect with technological developments and legislation and is generally good news.

    Be careful what you wish for, for years the fleet industry has been complaining that the manufacturer MPG figures do not reflect real life - not because they are ficticious but because as everyone knows they are measured in a European agreed test environment that doesn't adequately reflect real life driving. Given that the CO2 figures are measured in essentially the same way, we have all been benefiting from this flawed system from a tax perspective. Despite CO2 reporting being around for 12 years, the fleet industry as a general rule still continues to not understand the direct link between MPG and CO2. We're now getting what we been asking for and have therefore just realised what that actually means. As I say, be careful what you wish for!
