1984 Ford Sierra XR4i

1984 Ford Sierra XR4i



This is our 1984 Ford Sierra XR4i which we got in March 2013.  She is quite jaded and has been unloved.  Our plan is to refreshen the motor (has over 300,000km’s), full bodypanel and paint, new wheels and maybe a Cossie look.

The Sierra XR4i was introduced in 1983 as the performance variant of the newly introduced Sierra, with flamboyant styling and a 2.8 V6 engine taken from the Capri the car was an admirable performer and provided safe predictable handling. Over its brief two year production run 25,662 cars were manufactured before it was discontinued and replaced with the significantly improved XR4x4.


Sierra XR4i

The XR4i had been scheduled to replace the Capri 2.8 Injection in late 1982 and it was hoped that the XR4 would give a much needed halo effect to the lesser models. It became clear that the Sierra XR4i project had encountered major problems. Initially the car was destined to be fitted with a 2.3 injected version of the Cologne V6, prototypes had proved the car to be too slow and so engineers reverted back to the 2.8 Injected thus wasting 6 months of development time. The XR4i was planned to use the 2.8 Injected engine and five speed gearbox until 1988 when the unit was to be phased out in favour of the new 2.9i engine and gearbox.

The engine was a 2,792cc evolution of the Cologne V6 overhead valve pushrod engine fitted with Bosch K Jetronic fuel injection. In the Sierra the car generate 150bhp @ 5,700 rpm and 162 lb/ft @ 4,300 rpm, this was 10 bhp less than in the equivalent Capri, the drop in horsepower being attributed to the XR4i not benefiting from a dual exhaust.


2.8 Cologne V6

The front suspension used MacPherson struts with coil springs and integral shock absorber with Bilstein Strut insert, as with base model Sierra’s the car was fitted with an anti-roll bar this being of a larger diameter than on the standard Sierra models. The car was fitted with independent rear suspension with progressive rate coil springs, telescopic gas filled shock absorbers, semi trailing arms and an anti roll bar.

The Sierra XR4i was fitted with a unique 3 door body shell (costing millions of pounds in additional tooling), behind the front doors the XR4i was fitted with two rear windows, the rear quarter window was fixed with the second window being of the opening variety. The shell incorporated further aerodynamic tweaks including aerodynamic polycarbonate body mouldings along the side and a twin wing rear spoiler made from glass filled Nylon, this being mounted on the tailgate. The spoiler increased the cars stability in cross winds and reduced rear end lift, these modifications helped to improve the drag co-efficient of the XR4i to 0.32, down from the 0.34 of the standard Sierra.

The model was fitted with ventilated front discs coupled with rear drum units, the braking efficiency was improved with the addition of vacuum servo assistance. Power steering unlike its Capri Injection cousin was an optional extra. The car was fitted with 5.5” x 15” alloy wheels fitted with 195/60 VR15 wheels, these being narrower than tyres fitted to over similar performance Fords for the aerodynamic benefits.


Rear of the XR4i


The Sierra XR4i featured many standard fit items including sports seats, stereo with electronically retracting aerial, electric adjustable heated mirrors, height adjustable drivers seats, electronic boot release and a graphic module included in the dashboard that indicated issues with the car including bulb failure and low temperature warnings. From September of 1984 central locking, electric front windows, tilt and slid glass sunroof and tinted windows became standard fit. At this time a deeper shade of red was chosen for the bumper and body moulding inserts, the red striping was removed from the dashboard, steering wheel and gear knob.

Manufacture of the car began in Ford’s Ghenk factory in Belgium in February of 1983 and the car went on sale in May 1983 at a cost of £9,170. Production lasted little over two years with the car having poor sales, in fact the XR4i was outsold comprehensively by the aging Capri Injection that was developed by comparison on a shoestring. The car was eventually discontinued in 1985, replaced by the four wheel drive Sierra XR4x4.

Although Ford registered some cars in February 1983 for brochure and photographic use, notably the GJN, JNO reg numbered cars, the Press Fleet JVX**Y final spec cars were registered on this day 1983. These cars were then run in and evaluated by the British press with articles printed from April onwards. The Ford Sierra family car was announced in 1982, with the car going on sale in the autumn of that year, it was to replace the much loved but visually dated Cortina range. Bob Lutz, who was Ford Of Europe’s resident petrol head in the early 80`s conceived the idea of a “Super Sierra” after seeing the Probe III concept car of 1981. His ideas, included a special 3 door, 6 window (later to be known as 6 light!)body shell, and as many of the Probe features as possible. It had to have the performance to match this Futuristic look( 120/125 MPH and a sub 9 second 0-60 sprint) he was also keen to have the Cologne 2.3 V6 engine with Bosch K-Jetronic a new 5 speed gearbox and of course be RWD. By the summer of 1982 the prototypes with this power train were not performing, mainly due to lack of torque, and to cut a long story short the 2.8i engine from the Granada and,the then new, Capri 2.8i was quickly engineered to match the chassis of the newly named Sierra XR4, the i for injection was added later, but it was to late to stop the production of the 10000 pieces of glass for the “6 light shell” which had “XR4″ printed into them. The very luke warm reception of the Sierra range, when it went on sale, was a major concern for Ford, they hoped the XR4i would give a “Halo” effect for the rest of the range. The launched included TV adverts with the Chariots fire music,press adverts “Man and high performance machine in perfect harmony” and launch photographs taken at Silverstone, and to highlight the “future” with the Space shuttle. The Sierra XR4i shouted performance, and in a straight line it accelerated to 60 in less than 8 seconds and passed the ton in 22secs, no other 5 seater hatchback/coupe could live with it at the launch price of £9170. Ironically its closest competitor was its stable mate the Capri, which due to slightly different gearing was marginally slower (source Autocar, Motor, Car magazines ) As for maximum speed, Autocar achieved 128 mph on the Millbrook banked circuit,A German press car, 132 mph on a Autobahn, and a mad Italian hit 137 on a downhill section of Auto strada leaving a Alfa GTV6 trailing a few MPH behind in the process. Fuel consumption? 22/25 mpg,which was acceptable for oomph available. With a suspension set up similar to “lesser” Sierras it was no sports car, although it had Gas dampers,uprated coil springs, together with front and rear anti roll bars, the handling and ride were good, but not in a “hot hatch” or Sports car league. Most of the press cars were loaded with options like Electric windows,central locking, sunroof,headlight washers,trip computer or heated seats, these could add up to £1000 to the list price, strangely the desirable PAS was not fitted to any of the JVX cars. Launch colours were,Diamond White,Cardinal Red,Black,Caspian Blue, and Strato Silver, Graphite Grey was a rare factory order normally available in Europe only. WHAT THE PRESS SAID Comments were generally favourable,again highlighting the cars excellent performance, Auto car said “it would take a very fast car indeed to out accelerate the XR4i” “Fastest Ford but no sports car” Motor, “The 2.8 V6 fitted with Bosch K-Jetronic develops 150BHP @5700rpm and 160 lb ft @ 3800 rpm this sufficient to propel the XR4i to 130.8 mph” “Overall the XR4i is a very desirable package with few flaws” After all the hype, how did it sell? Slowly was the answer,the first customer cars were delivered in late May 1983, and a lot of buyers wanted to wait for the “status” of the new A registration.By the Autumn of 83 the public had made its mind up on the cars styling,you were either young and loved it or middle aged and loathed it.The only changes for 84 were a change in steering wheel, different stereo, and the standardisation of the mid 83 recall to help with the gearbox selection problem this also said goodbye to the famous red gearknob. For 1985 most of the options list was made standard,and the piping around the car was toned down.Talk of a minor re engineering programme of 15″ Alloys, Lsd,rear disc brakes, uprated suspension and a Turbo option never materialised and the writing was on the wall, and after approx 18000 sales Europe wide it was quietly dropped, to be replaced by the sober suited Sierra 2.8 XR4x4 5door and the 2.0iS.However if you wanted a faster Ford you had to wait until 1986 and the £15995 Sierra RS Cosworth!
