Ford Capri RS3100
In November 1973, at Ford's Halewood plant in the UK, production of the RS3100 began. Production of the RS3100 actually overlapped with the Capri MKII and was intermittent at best.

Homologated in January 1974 for the forthcoming UK Touring Car season, only 248 examples of the RS3100 were officially completed. They were an expensive road car at 2,450 Pounds and arrived right in the middle of the 70's oil crisis.

Ford Australia managed to import 50 examples of this "Special" Capri and many of these cars still exist today in private collections. These examples sold in Australia for $6,250.00

The RS3100 differed from the 3000GT with a larger bore and therefore an increase in capacity to 3091cc (188.6 cu in), a Weber 38 EGAS twin choke carburetor and a 9.0:1 compression ratio, which meant it developed 148bhp @ 5000rpm.

Its torque was rated at 187lb ft @ 3000rpm and it came with manual transmission only, with an optional limited slip differential. It had ventilated disc brakes, RS2600 German cast alloy wheels with 6in wide rims and had a top speed of 125mph (201kmh).

1973 had not been a good year for Ford in the European Touring Car championship. After two years at the top the highly acclaimed RS2600 had finally been overcome by BMW's 3.0 liter CSL. One of the major advantages that the CSL had over the RS2600 was its improved aero dynamics.

Nicknamed the "batmobile" due to its new wings the CSL knocked 15 seconds off the previous lap times at the Nurburgring, and was signigicantly more stable to drive. In order to redress the balance Ford needed a new contender. This was to be the RS3100.

To improve the aerodynamics of their racing Capri's Ford fitted newly designed front and rear spoilers. To meet the ETC rules these new aerodynamic aids on the racing RS3100's had to have been fitted to 100 road homologation cars. The distinctive boot mounted "duck-tail" rear spoiler and smaller front lip spoiler reduced the coefficient of drag (Cd) from 0.40 on the RS2600 to 0.37 for the RS3100.

The RS2600 had used the German 2.6 Cologne engine - which had been bored out as far as it would go. Therefore the RS3100 used an overbored Essex 3 liter unit producing 148 bhp (although the racing engines were bored to 3421cc and produced around 415 bhp). The road going homologation RS3100's shared many fetures with the RS2600's; brakes, suspension, wheels bumpers, and headlights were all the same.

The dummy side vents and interior were standard 3000GXL equipment but the 130mph speedometer, flat dish RS steering wheel, and AVO paint scheme were unique to the RS3100, as was an optional limmted slip differential.

Production ran from December 1973 to January 1974 and although 1000 cars were planned only 248 vehicles left the factory. These were launched into a country suffering from on oil crisis ; not the best market for a Capri with the largest engine ! At £2450.00 the RS3100 was nearly £800.00 more than a 3000E, and as the sales of the RS3100 were overhadowed by the launch of the MkII Capri in early 1974 in is no wonder that this car is one of the rarest going!
