    Mitsubishi Admits To Cheating Fuel Economy Tests, 625,000 Vehicles Involved

      Another automaker admits to cheating fuel economy tests

    Mitsubishi Motors has admitted today to manipulating fuel economy tests for 625,000 vehicles sold in Japan.


    The manipulation involves four kei (small-capacity engines and compact dimensions) cars; Mitsubishi eK Wagon, Mitsubishi eK Space, Nissan Dayz, and Nissan Dayz Roox. Out of the total 625,000 vehicles, the majority of the vehicles are the Nissan models.


    "The wrongdoing was intentional. It is clear the falsification was done to make the mileage look better. But why they would resort to fraud to do this is still unclear," said Mitsubishi Motors President Tetsuro Aikawa at a press conference.


    According to BBC News, the manipulation was done by adjusting the tire pressures when testing fuel economy on a rolling road. Nissan uncovered the manipulation as they were unable to replicate the fuel economy figures that Mitsubishi got.


    "This discovery was made during Nissan’s assessment of data from the current model as part of our development of the next-generation vehicle. We immediately brought the discrepancy to the attention of Mitsubishi, as they are responsible for the development and homologation of the current vehicles. In response to Nissan’s request, Mitsubishi admitted that data had been intentionally manipulated in its fuel economy testing process for certification," Nissan said in a statement.


    Both Mitsubishi and Nissan have stopped selling the models and are currently figuring out a compensation for affected owners. Mitsubishi has also announced they will be conducting an investigation into overseas models as their internal investigation showed the manipulation was used on other Mitsubishi products.


    "We will investigate why this happened and prevent a recurrence. We will inform our customers. I feel horrible they were given the wrong numbers," Aikawa said.


    After the announcement was made, shares in Mitsubishi dropped 15 percent, knocking off about $1.2 billion of the company's market value.


    This is another black mark for the Japanese company. For more than a decade, Mitsubishi has been trying to regain confidence from the market after it was revealed the company covered up a number of defects involving axles that could cause the wheels to detach.


    “It’s again bad for the company’s image. It’s not the first time for Mitsubishi to have this kind of issue, and this definitely won’t help them rebuild their reputation,” said Seiji Sugiura, an analyst at Tokai Tokyo Research Center to Automotive News.

    Improper conduct in fuel consumption testing on products manufactured by Mitsubishi Motors Corporation (MMC)


    In connection with the certification process for the mini-cars manufactured by MMC, we found that with respect to the fuel consumption testing data submitted to the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), MMC conducted testing improperly to present better fuel consumption rates than the actual rates; and that the testing method was also different from the one required by Japanese law. We express deep apologies to all of our customers and stakeholders for this issue.


    The applicable cars are four mini-car models, two of which are the "eK Wagon" and "eK Space" which have been manufactured by MMC; and the other two are the "Dayz" and "Dayz Roox" which have been manufactured by MMC and supplied to Nissan Motors Corporation (NM) since June 2013. Up until the end of March 2016, MMC has sold 157 thousand units of the eK Wagon and eK Space and supplied 468 thousand units of the Dayz and Dayz Roox to NM.


    Since MMC developed the applicable cars and was responsible for obtaining the relevant certifications, MMC conducted fuel consumption testing. In the process of the development for the next generation of mini-car products, NM examined the fuel consumption rates of the applicable cars for NM's reference and found deviations in the figures. NM requested MMC to review the running resistance(*) value set by MMC during tests by MMC. In the course of our internal investigation upon this request, MMC learned of the improper conduct that MMC used the running resistance value for testing which provided more advantageous fuel consumption rates than the actual rates. MMC will sincerely respond to our customers who own and use the applicable cars.
    (*) running resistance: rolling resistance (mainly generated by tires) and air resistance while vehicles are moving


    We have decided to stop production and sales of the applicable cars. NM also has stopped sales of the applicable cars, and MMC and NM will discuss compensation regarding this issue.


    During our internal investigation, we have found that the testing method which was different from the one required by Japanese law has been applied to other models manufactured by MMC for the Japanese domestic market.


    Taking into account the seriousness of these issues, we will also conduct an investigation into products manufactured for overseas markets.


    In order to conduct an investigation into these issues objectively and thoroughly, we plan to set up a committee consisting of only external experts. We will publish the results of our investigation as soon as it is complete.

    Was just reading this on Bloomberg.




    Pretty interesting but nothing like what VW did. Here via over inflation of tires and tweaking things on the car to reduce air resistance they got higher ratings. Not unlike what FORD also did to get higher MPG ratings.


    This is recoverable fast and easy and minimal penalty.


    VW did was far worse and will hurt them long term. Best thing is to just buy the auto's back, crush them, pay the penalty and move forward.


    Best solutino for VW would be to give a current emissions legal equal auto to the auto owners and call it good. 


    Talk about good will and how that would give them fans and social media good will.

      Rumor has it that Mitsubishi is working on a return of the Lancer Evolution as a high performance sedan and hatchback. The car could be one of the first results for Mitsubishi of joining the Alliance with Nissan and Renault.  The new Lancer Evolution would use the alliance's modular CMF platform, shared with the next generation Renault Megane RS. 
      Under the hood would be the powertrain from the Megane, a turbo-charged 2.0-liter 4-cylinder producing up to 341 horsepower.  While the Renault would stick with front-wheel drive, the Mitsubishi would get a version of their S-AWC all-wheel drive system.
      As Renault is just now updating the current Megane line, any Mitsubishi Evo that comes from it is still years away and yet to be green-lighted. So don't hold your breath just yet.

      Seven years ago, I drove the previous-generation Mitsubishi Outlander for a week-long review. There was a lot to like about the previous model as it featured distinctive shape, comfortable ride, and being somewhat fun to drive. But in other areas, the model fell a bit flat. Poor material choices, firm ride, and the optional V6 engine feeling slightly lackluster. I ended my review with this,
      “Mitsubishi has shown a new Outlander at the Geneva Motor Show earlier this year. Underneath the Outlander’s new sheet metal lies a new vehicle architecture and will have the choice between gas and plug-in hybrid power. The new Outlander also gets revised interior and new safety equipment. The question is will the new Outlander be able to fix the problems of the current one?”
      It has taken a fair amount of time to get my hands on the new Outlander. In that time, Mitsubishi has made a number of changes and updates to the Outlander lineup such as a revised exterior. Was it worth the wait?
      The Outlander’s shape is nothing too special with rounded corners, large glass area, and a set of 18-inch alloy wheels that comes standard on most models. For 2019, Mitsubishi has updated the Outlander’s front end with a new grille shape, headlights, and more chrome trim. It does help spruce up the design that has been with us since 2014. My only complaint is the dark silver paint on my tester. It makes the vehicle look like a giant blob. There isn’t anything that sets the interior apart from rivals. The design is somewhat plain, but material quality is quite surprising with an abundance of soft-touch materials. There is a fair amount of piano black trim, which does attract fingerprints. All Outlanders come with a 7-inch touchscreen running Mitsubishi’s latest infotainment system is standard. Those wanting Apple CarPlay and Android Auto need to step up to the SE or higher. My experience with the system mimics the Eclipse Cross; lags behind the competition in terms of the interface and performance, but its a huge step forward from the previous system. The Outlander is one of the few models in the compact crossover class that can boast having three-rows to allow seating for seven. This seat is best reserved for small kids due to the limited amount of leg and headroom. Having the third-row also eats into cargo space - 10.3 vs. 33 cubic feet with the seats folded. Front and rear seating is fine. There’s enough padding to keep everyone comfortable on a long trip, and most passengers will be able to stretch out. Most Outlanders come equipped with a 2.4L four-cylinder engine producing 166 horsepower and 162 pound-feet of torque. This is paired with a CVT and the choice of front or Mitsubishi’s Super All Wheel Control. Step up to the GT to get a 3.0L V6 packing 224 hp and 215 lb-ft of torque. There’s also a PHEV option which I talk about more in this first drive piece. The 2.4 is serviceable around town with brisk acceleration and minimal noise. But take the Outlander on the highway or fill it up with people and cargo, and the 2.4 feels overwhelmed. Not helping is the CVT that will drone quite loudly when you plant your foot on the gas. Fuel economy is mid-pack with EPA figures of 24 City/29 Highway/26 Combined for the AWD version - front-wheel drive models see a one MPG improvement. My average for the week landed around 24. One area that I was surprised by the Outlander was the ride. Over the varied surfaces on offer in the Metro Detroit area, the Outlander’s suspension smoothed out various bumps. It doesn’t feel comfortable around corners, showing noticeable body lean and a disconnected steering system.  The Mitsubishi Outlander answers the oddly specific question of, “what is the cheapest three-row crossover I could buy?’ I can see why someone on a tight budget would consider one as the Outlander provides a lot of standard equipment, along with seating for seven at a low price. It doesn’t hurt that Mitsubishi’s 5 year/60,000 mile new car warranty does provide peace of mind for those who want a bit of security. But it does become a poor value the higher you climb in price. My Outlander SEL S-AWC tester starts at $29.095. With the optional SEL Touring Package (forward collision mitigation, adaptive cruise control, LED headlights, and a 710W Rockford Fosgate audio system) and carpeted floor mats, the price ballooned to $33,225 with destination. For that amount of cash, you get into a decently equipped Volkswagen Tiguan or Mazda CX-5. I know dealers put cash on the hoods - most dropping the cost to under $30,000, but it is still a tough sell. Disclaimer: Mitsubishi Provided the Outlander, Insurance, and One Tank of Gas

    • '69-70 Stingray coupe, white, very clean, cruisin. circa '85 Corvette coupe, dark blue, very clean, cruisin.
    • I'm not a modern car styling fan but I think the Bolt looks fine, certainly no worse than any other in it's size class. But to those saying the 'Bolt doesn't sell well' are all wrong. This is the typical filter a GM vehicle must always go thru- "it must sell in the 100s of thousands because it's a GM, or it's a flop". Doesn't work that way, certainly not now. Tesla aside (and there, really only the Model 3 applies), the Bolt sells very well…. FOR AN ELECTRIC. The problem is NOT marketing or the looks or the price, it's the #4 selling BEV in the country. It outsells the Model S and is neck & neck with the Model X. The problem is electrics don't sell well compared to IC vehicles. AT ALL. The Bolt is electric. Duh.    
    • That sounds an awful lot like a homophobic insult. Well, just relax there junior.   
    • I will second several points echoed from the past (one of which dfelt already pointed out). The looks are a problem for a lot of folks. It looks like a CUV yet it offers nothing that other CUVs offer, like AWD or 4WD. That kills a huge subsection of potential CUV buyers looking to go green. Second, and this is the big one, has been total lack of marketing, much like the diesels certain folks here crow over. I worked at a Chevy dealership last year and during that time they had exactly one Bolt that sat for almost two months with a $44K price tag on it. Most of the sales people knew jack and $h! about the car and that price was a huge pill to swallow for a lot of folks. All of this had nothing to do with the powertrain and that’s what the dinosaurs don’t get. It has said a million times in the last, that had the EV tech gone in something more like the Equinox, sales would be better (potential high price not withstanding). I don’t know why the EV hater here doesn’t get what has been discussed a thousand times now but those are the simple facts.  Diesels don’t sell for $h! here either and their issues have cost manufacturers BILLIONS. Guess, by your logic, we should give those up too right? Just for you @ocnblu, this article covers the issues facing the Bolt perfectly. Read it, understand it, and move on from your endless troll act.  https://www.google.com/amp/s/www.forbes.com/sites/brookecrothers/2019/07/21/chevy-bolt-the-best-ev-youve-never-heard-of--still/amp/
    • Ah deflection, the favorite practice of the defeated. I actually have every song in my collection that I’ve posted here. The title of the thread is “What are you listening to?” not “Be careful what you post or you may affect Blu’s delicate sensibilities.”. Again, if you have a problem with that, just add me to the “ignore” list in your account settings because I’m not changing a thing. It’s that easy.    And you know exactly what you can do with the insult snowflake.  Part of my actual YEAR OLD playlist that Mr. Delicate has a problem with.    @ocnblu Seek help for that paranoia.
