Some Mercedes, BMW and Peugeot models consuming around 50% more fuel than official results, new study reveals

New cars, including the Mercedes A, C and E class, BMW 5 series and Peugeot 308, are now swallowing around 50% more fuel than their lab test results, new on-the-road results compiled by Transport & Environment (T&E) reveal. The gap between official and real-world performance found in many car models has grown so wide that it cannot be explained through known factors including test manipulations. While this does not constitute proof of ‘defeat devices’ being used to fiddle fuel economy tests, similar to that used by Volkswagen, EU governments must extend probes into defeat devices to CO2 tests and petrol cars too.

Fuel consumption meters, saving motorists up to €50 a year, get MEPs’ backing

Eco-driving technology that will save motorists €30 to €50 year today received the backing of MEPs who called for mandatory fuel consumption meters for all new cars, vans and trucks. The European Parliament’s environment committee overwhelmingly voted for the meters to be fitted and permanently visible in all new vehicles from 1 January 2019, leading to fuel efficiency gains of 2-3% per year.

Nissan accelerates Europe’s race for cleaner cars - report

Nissan has made the most rapid progress in cleaning up emissions from its fleet in Europe with a 12.1% reduction in official CO2 figures last year, T&E’s latest cars and CO2 report reveals. The report, in its 10th edition, tracks the annual progress made by vehicle manufacturers to reduce fuel consumption and CO2 emissions of new cars. It also found Nissan has been the best performer in driving fuel efficiency since EU CO2 limits were proposed in 2008, cutting CO2 by an average of 5.5% annually.

Peugeot Citroën lands top award for fuel-efficient cars

Have you ever wondered which car brand makes the most fuel-efficient cars? The award in 2014 goes to Peugeot Citroën with cars averaging 4.5 litres per 100km (110g CO2/km) – making it the lowest carbon carmaker. This is a key finding of the 10th edition, of ‘How clean are Europe’s cars?’ by sustainable transport group Transport & Environment (T&E), which annually tracks progress made by carmakers to reduce fuel consumption and CO2 emissions of new cars.

Vehicle fuel efficiency standards can help EU countries halve their climate obligations from transport – study

Europe can only meet the climate targets Heads of State agreed on for sectors outside the Emissions Trading System (ETS) if it sets fuel efficiency standards for new cars, vans and lorries by 2025 or earlier, a new study by Transport & Environment (T&E) reveals [1]. In a middle-of-the-road scenario where transport would cut CO2 emissions by 30% by 2030 [2], the study found that CO2 standards for all vehicles (cars, vans and lorries) in 2025 and 2030 would deliver a whopping 42% of the emissions reduction required from transport. 

EU adopts world’s first test for diesel car emissions ‘on the road’

EU regulators have today agreed new test procedures that will, for the first time, measure the ‘real world’ emissions of diesel cars under the Euro 6 air quality standard. It will require vehicles to be tested on roads rather than in laboratories, overcoming obsolete tests and ‘cycle beating’ techniques used by carmakers to achieve results in tests many times lower than actual air pollution emissions on the road.

Car CO2 progress slows while gap with reality widens, warns T&E

Carbon emissions of the average new car sold in Europe fell 2.6% in 2014 to 123.4g/km, according to official figures published today by the European Environmental Agency (EEA). Sustainable transport group Transport & Environment (T&E) warned that most of the improvement was being delivered through cheating in flawed tests with no benefits for drivers in better fuel economy on the road.

T&E welcomes common rules to enable smarter road tolls in Europe

Earlier this week, Violeta Bulc, the EU’s head of transport, announced plans to develop a Europe-wide scheme to charge lorries and cars for using roads. Bulc clarified that the scheme would be optional, meaning that countries like the UK could opt out if they want to. The Transport Commissioner also stressed that the amount of the fee should be based exclusively on the distance driven and should not be time-dependent, which would bolster more efficient use of roads.

Netherlands tops EU ranking of lowest CO₂ emissions from new cars – Germany and Poland the laggards

Green Car Tax rating highlights EU countries with the most and least supportive tax arrangements to encourage low-carbon, fuel efficient cars. Initial registration taxes (purchase taxes) and company car taxes that are steeply differentiated by CO₂ boost the purchase of lower-emissions cars in the Netherlands, Denmark and France.

Mercedes ranks No 1 in Europe’s list of fuel economy cheaters – report

If your new Mercedes car swallows 40% more fuel than the brochure promised, it’s not due to your heavy-footed driving. Rather it’s because Mercedes are the current leaders at manipulating the way vehicles are tested, producing official fuel economy figures in the labs that cannot be replicated in the real world. That’s the findings of Transport & Environment’s (T&E) 2014 Mind the Gap report, which analyses real-world fuel consumption by motorists that highlights the abuses by carmakers of the current tests and the failure of EU regulators to close loopholes.
