Mitsubishi reveals fuel economy test misconduct involving 625,000 cars

Nissan DayzMitsubishi has revealed details of misconduct in official fuel economy tests after some of its models were found to have failed part of the test.

The firm has admitted falsifying fuel economy data for 625,000 cars across four model lines: most of the cars were sold in Japan.

Rather embarrassingly, only 157,000 of the cars are branded Mitsubishi: Japan’s sixth-largest car company also built the models for Nissan, of which 468,000 cars are affected (the Nissan Dayz is pictured above).

What’s more, it was Nissan that discovered the fuel economy inconsistency and reported the problem to Mitsubishi…

The firm no longer builds the affected cars; Mitsubishi and Nissan are now in compensation talks.

Mitsubishi president Tetsuro Aikawa led company executives onto stage during the press conference this morning – and bowed deeply before revealing news of the economy misconduct.

The affected cars are: 

  • Mitsubishi eK Wagon
  • Mitsubishi eK Space
  • Nissan Dayz
  • Nissan Dayz Roox

The firm held the press conference this morning – but stock markets already reacted with shares plunging 15% on news of the misconduct revelation.

This is the biggest one-day drop in Mitsubishi shares in more than a decade.

Bloomberg revealed the misconduct centred around loading on individual tyres during rig testing, to make fuel economy appear better than it would be in reality.

Mitsubishi’s revelation follows the huge Volkswagen emissions scandal, where pre-installed software detected when cars were being tested on rigs and altered vehicle emissions to ensure they passed the tests.

UPDATE: News has since emerged that Mitsubishi offices in Japan have been raided by officials. A government spokesman is quoted by BBC News saying they’re treating it as “a very serious case” and have given Mitsubishi until 27 April to respond.

Driver compensated after car fails to achieve claimed fuel consumption

Driver compensated after car fails to achieve fuel consumption claims

A man in New Zealand has been awarded $6,000 in compensation after his Ford Kuga failed to reach the manufacturer’s claimed fuel economy figures.

Bruce Campbell bought a Ford Kuga Titanium Ecoboost AWD last year, reports the NZ Herald, after being told it’d use 7.7 litres of petrol per 100km (36.7mpg).

But Campbell could not achieve better fuel economy than 9.7 litres per 100km (29.1mpg) – and at one point the Kuga was averaging 12.9 litres per 100km (21.9mpg).

When he contacted his dealer, Wanganui Motors, they told him the car was still ‘bedding-in’ and fuel economy would improve.

The owner kept the car for around 11,000km (6,835 miles) before trading it in and taking his dealer to an official disputes tribunal.

The tribunal found that Campbell had been misled but the dealer had relied on incorrect information given by Ford.

He was awarded $6,000 in compensation – 0.75c for every km he travelled in the car.

Do car manufacturers in the UK mislead customers in fuel economy claims?

It’s fair to say that, in the UK, most drivers will struggle to reach the official fuel consumption figures provided by manufacturers.

That doesn’t mean that we will be able to sue manufacturers for false MPG claims, however.

All new models are put through a strict fuel economy test known as the ‘NEDC’ (New European Driving Cycle).

This standardised test measures a car’s performance in laboratory conditions and has been criticised for not replicating real-world conditions.

This means the official fuel consumption figures do differ from those you’re likely to achieve – but they still allow buyers to compare models like-for-like.

As this is an official European test, manufacturers have no control over the outcome. Therefore, it would not be possible to challenge their ‘claimed’ fuel economy figures.
