How Do I Know If It's MHD?

Modification Details

How Can I Tell If The Car Is An MHD?

The Badge

Originally this was easy, you just looked on the boot panel for the MHD logo.

However, people like to debadge the cars to make them look cleaner.
Also, people remove the badge to try and trick people into thinking it's not an MHD.

The Switch

The next way is to look for the MHD ECO button just in front of the gear stick.

If it has this switch, it's an MHD.
However, there have been cases of these switches also being removed to trick buyers.

The Speedo

When you turn the MHD-equiped fortwo ignition on, you should see ECO show up on the dash.

However, it's easy to desolder the LEDs, cover them over or change the speedo.
This could and does happen. Again, to fool people into buying the car.

Vehicle Identification Number (VIN)

Each car has a unique number that is really hard (and ultimately pointless) to replace.

The VIN code can be found in a small window in the lower right hand side of the windscreen...

...and on a sticker in the door shut.

You can assume that this number is correct and with the first 6 numbers will tell you all you need to know.

If the VIN starts with the following numbers, it is an MHD.

451334 (coupe)
451434 (cabrio)
451380 (coupe)
451480 (cabrio)

Between October 2007 and October 2008, the MHD system was available as an optional extra.
Very few were sold with this extra but they had the codes 451334 and 451434.

From October 2008, the MHD became standard and you could no longer buy the non turbo model without MHD.
These models came with the codes 451380 and 451480.

The Owner's Document

In the UK, the owner's document is called the V5C. I'm sure it's called other things in other countries.

On the document is every piece of information you require about the car.
What we are looking for is the emissions in CO2 g/km.

If this figure is 97, 98 or 100, you have an MHD.
All other petrol models start at 112 and go upwards from there.

Cost Of Road Tax (UK only)

In the UK, the road tax is now called VED so they didn't have to spend the money actually fixing the roads.

If your petrol smart 451 has free UK road tax, it's an MHD.
All other petrol 451 models are £30 to £105.
