At present I am getting ready for certification. There are a set of regulations that need to be followed available from LVVTA. I don't an electrical WOF as the charger wont be installed in the car and therefore no mains voltage will be in the car. After Certification I will just need to get standard...

The torque is 100Nm from 0 to 4200rpm, then it tapers off. Which is different from the curve around 5000 rpm with the original engine. The power is 74kW. What this means is that it is quite different to drive as you have full torque from when the motor is stopped. I don't need to use the clutch to s...

Engine Bay - Hmmm I don't seem to be able to upload images. You will just have to take my word for it

Hi, I have been converting my 1993 NA 1.6 MX5 to electric, and am nearly ready to take it for certification. It is very slightly heavier than it was originally, but it will be OK, if I can show the weight of a standard model with all the options fitted. What I would like to do is borrow an Automatic...

The project is quite expensive. I estimate about $25,000 for the parts. The batteries are about $11,500 and motor about $7500. Fortunately I can do most of the work myself, so there will be no labour in it. I was planning on doing a series of videos on youtube as the project progresses, but can post...

For my design the final weight of the car will be: Curb weight after conversion 1091kg + 2passengers @80kg = 160kg Final weight 1251kg To pass the standard the final weight must be less than the GVM which is 1060 for my car from Mazda. The GVM given to me by Mazda is really the curb weight without p...

And this part too:
NOTE 2: When weighing a vehicle to determine that the manufacturer’s GVM has not been exceeded, a simulated occupant weight of 80 Kg must be applied to each seating position, and any equipment must be in its maximum weight state, such as full water storage tanks.

The secion of the standard that deals with weight is: An electrically‐powered low volume vehicle must not exceed the vehicle manufacturer’s gross vehicle mass or either of the vehicle manufacturer’s axle ratings, for that make and model of vehicle. At present the certifier is stating that I can't ex...

I put it on the scales and these were the figures Hard top on 1017 kg Hard top off 995 kg At the time it had just a fraction less than 1/4 of a tank of fuel. The standard can be found here: http://www.lvvta.org.nz/documents/standards/LVVTA_STD_Electric_and_Hybrid_Vehicles.pdf It is not the only stan...

To meet the LVVTA standard the vehicle must be less than the GVM after conversion including 2 x 80kg passengers.

I have an update on the GVM issue: Mada here in Christchurch and head office in Auckland were able to give me a curb weight of 983kg. They were unable to provide a GVM. The 983kg curb weight would be correct for the New Zealand new models which didn't have hard tops, power steering and AC. I had an ...

The car has power steering and AC, so I expect that is some of the weight difference. The GMV on my registration papers is 1050. This should be the wight including passengers and luggage. However with a full tank of gas and the hard top on it would be very close to 1050 without any passengers and lu...

Ooops I used the wrong numbers. The weight of my car is:
Hard top on 1017 kg
Hard top off 995 kg

Does anyone know the Gross Laden Weight of a 1993 NA 1.6 MX5? It is also known as GVWR(gross vehicle weight rating) or GVM (gross vehicle mass) I have weighed mine mine with the hard top on and it was 995kg with about 1/4 of a tank of fuel. The Certificate of registration for my car lists the GVM of...
