This identification guide / buyers guide has been written for those interested in the Ford Escort MK1 RS1600 (For the MK1 RS2000, click here). The MK1 RS1600, along with the RS2000, have become very desirable collector cars due to their success in motorsport, most notably in rallying. Like many collector cars, the RS1600 was built on the standard MK1 escort coupe body shell (with some difficult to spot modifications), and therefore, potential for "replicas" of this model to be produced is substantial. This guide attempts to outline essential information about the RS1600, so people can confirm whether the cars they are looking at purchasing or restoring are in fact genuine cars.
This guide provides identification criteria for external features, interior features, vehicle options and of course the relevant engine and chassis number details which were unique to the MK1 RS1600.
Number produced: Estimated between 950 - 1,137 produced (depending on the source)
Period of Manufacture: 1970 - 1974

The MK1 RS1600 had the following external features, which make a good starting point for identification of a genuine car:
The RS1600 is very similar to the RS2000 in appearance, however, the RS1600 were not given side stripes / bonnet stripes in the factory. Many people have applied these aftermarket, but they were not an original item, and along with the badging, sets them apart from the RS2000 aesthetically.
The RS1600 had the following interior features. Note, many of these features were also standard in other Escort MK1 models, and are not necessarily unique to the RS1600:
Materials / Fabrics:
The Ford Escort RS1600 was originally available in the following paint colours listed below, and demonstrated in the images. Early RS1600's were reportedly available only in Diamond White, so this colour will be more prevelant on 1970/71 model cars. The paint code is listed on the cars chassis plate under "Colour", where the Ford code will be listed. It is also listed on the Vehicle AVO plate, located on the front slam panel (Note - AVO plate and Chassis plate pictured are not necessarily from an RS1600). Below, we have also given the Ford, Ditzlet and DuPont codes for each colour where possible.
Note, if a car was a special order colour, the code "Y" would appear on the chassis plate, and an individual colour applied, which would hopefully be described in the vehicles order records. These codes above are thanks to paintref.com. At Paintref.com you can check these and colour chips yourself by searching their database.
There may be additional colours that were available, and we would really appreciate you contacting us if you have further knowledge in this area, so we can update this section. Alternatively, login and comment below so everyone is informed!
Location: The chassis number is located in two positions on an Escort MK1 RS1600. Firstly, it is stamped into the aluminium Ford chassis plate (under the heading "Vehicle No."), which is pop riveted to the front bonnet slam panel. Secondly, the number is stamped into the body panel on the top of the right hand side suspension tower. The numbers in both locations should of course match, and in a fully original car, will also be stamped on the engine block or head. Given that the years of manufacture overlap between the RS1600 and RS2000, chassis numbers may often appear to be very similar.
Format: A Ford Escort RS1600 should have a chassis number in the following format, subject to the decoding guide below:
MK1 RS1600 (example only) Chassis Number: BFATKP54456
1st digit: (Vehicle Source):
2nd digit (Assembly Plant):
3rd digit (Model):
4th digit (Body Type):
5th digit (Year of Manufacture):
6th digit (Month of Manufacture):
7th – 11th digit (Serial Number):
Engine Number Prefix:
RS1600's have completely different stampings to the RS2000's, as the RS1600 used a Cosworth based alloy block design with a twin OHC head. Information regarding engine number castings and their locations have been hard to come by, and very inconsistent, but here is what we have been able to find so far from our research:
The engine block will be a "BDA" type block, (belt driven early series engine). Either the head or engine block should have a number cast into it sarting with "WE" or "HE" , followed by a build number (being the vehicles chassis number). RS1600's may also have an engine number ending in "BA". The information is a bit inconsistent between sources, as we understand the engines were not all built at the same location / time, so stampings / castings differed.
Many people replace engines in Escorts with more common "20", "205" or "202" Ford Pinto blocks, so look out for those blocks which have a completely different look (long thin rocker tappet/cover as opposed to the wide ford badged twin OHC cover on the RS1600.)
If anyone is able to provide more clarity on the engine block / head castings for the RS1600, please contact us or login and comment below so we can update this section.
Chassis Plate additional information:
The following information should display under the other titles of the Vehicle ID / chassis plate for a Ford RS1600 MK1, as shown on the attached chassis plate image (note the attached image is just an example and not from an RS1600):
- Digit 1 (B = Britain, C = Ford Britain affiliate company / G =Ford Germany)
- Digit 2 (A = Escort)
- Digit 3 (T = 2 door)
- Digit 4 (Each represents a model year per the chassis number decoding above. E.g. N = 1973)
- Digit 5 & 6 = Engine code (Should be "NE")
Body / AVO plate:
The body plate or AVO (Advanced Vehicle Operations) plate as it is usually called, can also assist in the identification of a genuine MK1 RS1600. The AVO plate is located to the right of centre slam panel (if you are facing the engine), and will have the letters AVO and the original colour code printed on the plate a few lines below that. The location is described again in the images, with an example of a plate attached.
