Converted Mazda5 EV Sets Single-Charge Distance Record At 457 Miles


Andrej Pečjak from the Institute Metron in Slovenia, Europe on October 12th set a new distance record in a Mazda5 converted to electric drive and called Motorn 7.

The car drove in normal traffic with an average speed just 65 km/h (40 mph), but its large 86 kWh battery pack (plus 12 kWh in a reserve module) provides Motron 7 with substantial range. More than 400 km at 130 km/h (81 mph).

The motor is just 50/65 kW (continuous/peak), but combined with a 5 speed gearbox can take Motron 7 to 178 km/h (110 mph).

Andrej Pečjak stated:

“If the car was made in big series its price would be some EUR 50,000.”

Institute Metron is proud of the performance of the project and its long range:

“Metron 7 attended WAVE 2014 World advanced vehicles expedition where it wan the range competition. When the last Teslas stopped because there was no more energy left in batteries, Metron 7 could still do another 130 km!”

    There are some really interesting data here. One is the coefficient of drag of 0.27 compared to Tesla’s 0.24. That is really good for a compact, bulky and not very streamlined car. Another is weight at only 1700 kg. That is some 400 kg lighter than the Model S.

    With only 50 kW motor the car can do 178 km/h which is impressive. Of course it has to do with the gear box. Involving a troublesome 5 speed gearbox is also quite impressive for an EV, and getting it all to work.

    1. BraveLilToaster says:

      The transmission is probably the standard transmission that comes with a Mazda 5 in the first place, so it’s not specifically geared for the torque curve of the electric motor.

  2. Dr. Kenneth Noisewater says:

    While I prefer having the smooth power delivery of a “1-speed”, I don’t see why an EV couldn’t have a DCT gearbox with computer control of the clutch to do rev matching and mostly eliminate clutch wear. Presumably, controlling an electric motor’s speed is quicker and more precise than controlling that of a combustion engine.

    Batteries manufactured by ???
    Compare and contrast the 605km Munich-Berlin record and fate of Mirko Hannemann’s DBM Kolibri A2. Buried by the auto establishment and their silent, compliant,client media.
    Oh – and DBM’s cells are good for over half a million miles.

    This is not a world record. My battery converted Zotye M300 EV travelled in Nvember 2012 from Shenzhen to Nanning on open roads for 801 km at high speed ( around 100 Km/h) and at the end of the trip there still was a 13% of the energy in the battery pack, before the BMS stop ( means 80% DOD). The energy density at a pack level was 250 wh/Kg. These batteries are available for selected costumers. Just contact with me.

      Why would costumers need batteries. Heated coats for winter I guess, or lights for a broadway musical.

    this event was covered by media world wide and i am quite surprise that Inside EVS is not aware of this news. It would be useful for the readers that your magazine could cover ( 2 years late ) how this world record for homologated road legal EV was achieved.

    1. Paul Govan says:

      – is there no (Youtube) video of the record?
      If not – why not ?
      Also – who independently verified the record ?

    I like the 160W drip charge PV they put on their for giggles.

    1. Cavaron says:

      Well, if they drove 450 miles with 40 mph, it took em more than 11 h, so a hole day of possible sunshine. Wonder how much power they could generate, more than 1 kwh is very possible – so given the cars efficiency, maybe 5 more miles because of PV. Not that bad 😉

  7. Miggy says:

    Now Mazda just needs to build a standard EV that can match this.

    1. vdiv says:

      Yes, and the thing is they don’t have to build one from scratch, at least not immediately, but just partner with a company that already has, and split the R&D cost.

  8. Bill Howland says:

    Very impressive. And I bet they didn’t need GM’s 50,000 engineers to help design it either.

    Now when can I order that overdue 400 mile battery for my Roadster that was hinted at a long time ago now?
