Ford Sierra (1982 – 1993) Review
Ford Sierra (1982 – 1993) At A Glance
The styling was so advanced, it still looks modern to this day
The running gear and engines didn't live up to expectation
The overtly aerodynamic Ford Sierra was the replacement for the much-loved Cortina. Sadly, it proved to be a slow seller early in its life, causing Ford management all manner of confidence issues when it came to the styling of its future models. But the Granada followed suit in 1985, and by the time of the 1987 facelift, the Sierra was selling strongly enough to remain in production for more than a decade.
At launch in 1982, engines were carried over from the Cortina, and the Sierra also maintained that car's rear-wheel drive layout. The idea behind that decision that was to keep servicing simple, and fleet managers on board. But the suspension system was uprated to mirror the set-up used in the Granada Mk2. The aerodynamics famously caused a number of motor way stability issues on the earliest cars, but these were soon fixed, but the damage was already done, and the 'jellymould' had to work very hard indeed to stave off the advances of the Vauxhall Cavalier Mk2. Advanced shape meant slow acceptance as a classic, but the Sierra is generally considered to be a quirky, interesting choice with plenty of '80s appeal.
Ask Honest John
Why does my Sierra have a metallic rattling sound at low revs?
January 0001Streamlining the future…
IT seemed that everybody loved the Cortina just a little too much. It did everything you ever needed a car to do, if only averagely. Pleasing Coke bottle inspired styling allied to simple rugged mechanicals combining to create the car that everyone wanted, the car ‘for Mr Average’. In one word, ordinary. However come September 1982, and shock waves were sent across the nation’s suburban driveways and motorway service stations, what was this Jellymould?
The Sierra, aka Project Toni, the joint Cortina/Taunus replacement exploded onto the scene, and for many long time fans of the blue oval, it was too hard to stomach. Publicly Ford was proud of its cutting edge design, but behind closed doors management heads were rolling even before the new car honeymoon had ended…
The man in the street was not alone in his bewilderment – back in early 1978, the American management was just as startled. Did its European cousins actually intend to market a car that looked like a motor show special to the fleets? If you wanted cutting edge you visited Citroen, surely? A mere year previously, the NSU Ro80 had sailed along with NSU marque into history – a victim of its own misguided reach for the skies. After all, this was the Ford Motor Company, the purveyors of solid sensible transport, not some exotic European carrosserie.The pitch
According to Ford’s Robert Lutz: ‘I gave him (Don Peterson) a small sketch to put in his pocket on his return to the US and inscribed on it the words “view daily until familiarity is achieved” It worked.’
However by coincidence Giorgetto Giugiaro tipped the balance towards the successful signing-off of the Toni project in its most advanced form. Unveiled at that year’s Turin motor show, the Isuzu Piazza prototype had been very well received; enough for the Ford boardroom to give this new ‘aero-look’ model the go ahead. Within two years, the Sierra was was signed off, and Ford management had been encouraged along the way by praise heaped on Giugiaro’s similarly sleek Lancia Medusa concept, a four door aerodynamic hatch-cum-supercar.
A total of $1.2bn had been set aside to develop, engineer and produce the car and its assembly lines.Robert Lutz (who would become Ford’s European chairman by the time of the Sierra’s launch) handed the reins for the Sierra project to Ford’s Vice president of Design, Uwe Bahnsen (a man who enjoyed sleek fastback designs, if the model Rover SD1 that graced his desk was anything to go by), something that would haunt in him the future.
Beneath him, Ray Evertz assembled a team of designers for Bahnsen, among them an ambitious young designer called Patrick Le Quement, the man responsible for the Cargo truck cab. Perversely although several alternative proposals were created for the Toni, it was deemed the original proposal was right from the start.
Developed without prior knowledge of the C3-generation Audi 100’s highly aerodynamic shape made aerodynamics de-rigueur, the Sierra’s cd of 0.34 had only been beaten by the Porsche 924 and Citroen GS in then-current production terms. And as for its middle market rivals, no-one had come close to that point.
Referred to as an Aeroback design by its creators, on account of its bustle at the rear, the Sierra sported a similar body shape to the recently launched Escort Mk3 (known internally as Erika). The later XR4i improved on the standard car’s cd figure by incorporating sculptured side panels to control air resistance across the wheel faces, as well as its iconic bi-plane rear spoiler. The result was a very impressive drag coefficient of 0.32.
Having said that, no production Toni could come close to matching the Sierra ‘taster’ prototype – the Probe III – of 1981. But, then, that did feature overtly aerodynamic features including Citroenesque enclosed rear wheels, and integrated door mirrors (which would appear on the production 1988 Probe coupe no less). That car’s cd was 0.25, although its main raison d’etre was to soften-up buyers hooked on the Cortina, selling them the idea of its sleek new replacement.
This revolution in mainstream car styling was impressive enough for the Sierra to be displayed in England’s Victoria and Albert museum during 1982.With added dash…
However, so as to not scare traditionalists, both a stylised finned grille and a flush nose cone (complimented with built-in driving lights) were offered, and hence defined the range topping Ghia and XR4 models, as objects of desire. All this was finished off with full flush wheel covers – the first European Fords to feature them.
The inside story was far more conventional, despite tipping the nod to BMW’s and Saab’s ergonomic command centre style of dash layout. Another unusual step was the two different dash mouldings dependant on specification: GL, Ghia and XR4i models were deeper and gained the Fischer C-Box cassette storage system and a four-way joystick fader control for the stereo system (Both a big sales draw in 1982).
The integrated warning displays on these plusher models (previously the domain of executive cars), alerted the driver of low fluid levels and brake pad wear. Additionally, the Ghia and XR4i models featured a vacuum fluorescent display alerting the driver to such dangers as lamp failure, doors ajar or freezing outside temperatures. No big deal today, but stepping into this from a Cortina must have seemed like a massive advancement. The stylised door panels with triangular moulded door latches/grab handles were an innovation too. All in all, it was quite pleasant, but as Uwe Bahnsen conceded at the launch, not so extreme as to frighten traditional Cortina/Taunus purchasers.The tech…
‘The Cortina’s dead – Long live the Cortina!’ screamed the headlines, when the Sierra finally made a bow on the 25 September 1982.
And right they were to do so, because under that memorable styling, beat a very conventional heart. There were no surprises or radical shocks in the technical specifications; the main improvement over its progenitor was the addition of independent rear suspension (apeing that of the Granada). Upfront, the tried and tested McPherson struts were complemented by the fitment of the anti-roll bar behind the struts.
That independent rear suspension layout consisted of an upswept over-axle crossmember, which carried the differential casing (itself to be used on the up coming 1985 Granda Scorpio) – each driveshaft was supported by a coil sprung trailing wishbone, with a self levelling system optionally available for the estate model.
Steering courtesy of a rack and pinion system featuring optional power assistance, and brakes were a standard mixture of discs and drums all-round. A pressure-sensing relief valve was fitted to prevent the rear wheels locking under heavy braking applications, and all models above 2.0-litres gained ventilated front discs. All very conventional.
The engines were pretty familiar, too. The range comprised of the overhead camshaft design Pinto four-cylinder and Cologne six-cylinder units. Simple, effective and lusty (in larger engined guises), they were capable of a service life of well in excess of 100,000 miles, even if the Pinto design favoured replacement camshafts at high mileage.
Available in 1.3-, 1.6- and 2-litre forms, the Pinto featured electronic ignition and revised cast exhaust manifolds in its new home. The V6 Cologne engine was available 2.0 (in Germany), 2.3- and 2.8-litre capacities, and was fitted with fuel injection to define the XR4i model’s sporting pretensions. An economical but sluggish Peugeot 2.3-litre four cylinder diesel could also be specified. But only if you were a masochist.
Transmission was by four- or five-speed manual, depending on model – all derived from the slick Type E ‘rocket box’, or a trusty three-speed automatic.Scandal!
Unfortunately though, the Sierra never clicked immediately, and sales fell well below expectations, and scalps were inevitably sought.
Uwe Bahnsen became the scapegoat for the whole Toni project, ended up leaving Ford for good. Stylist, Patrick Le Quement, also left the Merkenich studios, although he initially left for Detroit. Instead of succeeding Bahnsen as head of Ford design in Europe – the expected career path for someone who’d been responsible for the company’s hugely important mid-liner – he also left, a clear reflection of the Sierra’s underwhelming market performance.
But Le Quement would go onto greater things, becoming the figure head of Renault’s design renaissance during the 1990s. Uwe Bahnsen ended up teaching at the Art centre college of design in Vevey Switzerland. Sierra mastermind, Robert Lutz, made the Ford board of directors, but in 1986 joined Chrysler having been reprimanded for the lacklustre take up of the Merkur brand in the US, ironic as was spearheaded by a federalised version of the Sierra XR4i.
Even though the public was reluctant to embrace the Sierra, Ford’s PR department was pulling out all the stops, with the press seemingly in agreement of its advancement.
Four-page colour advertisements were placed in all the major national press, the Readers Digest and the TV Times (where a complete catalogue fell out at your local newsagents). Billboard posters sprung up, and 60 second commercials were aired, soothingly telling you that the Sierra was ‘Man and Machine in Perfect Harmony’. Your local toyshop would even sell you an accurate 1:36 scale Corgi model. In short, unless you lived in a cave, Warley’s marketing team made sure everyone knew there was a new kid on the block.
The press gave rave reviews too: Car magazine headlining its October 1982 issue with ‘SIERRA SHOCK! It really is a good car’. Steve Cropley summed-up his review, ‘Quite simply, Ford have done it all. They have built an all-new car which breaks all ties with feeble old Cortina, yet takes over those components which it was not possible (or affordable) to rebuild. It thoroughly deserves the tag “modern” and more to the point, it is thoroughly worthy of the eventual millions who will buy it.’ The trouble was they only eventually cottoned on in Britain after several year…
In Germany, the Sierra looked healthier, and was out-selling the Taunus by a factor of 3:1. It was possibly helped by the simultaneous arrival of the Audi 100 (at the Paris Salon premier both models were on adjacent stands) which also helped sell the benefits of aerodynamic design to the masses. Ostensibly, the launch of the new Ferguson (FF) Development’s 4×4 model and ABS was even delayed, because the Sierra had more than plentiful media exposure. So the PR department would have us believe…
The Cortina was the real problem in those early months, though. Dealer bonuses to clear stock offered as much as £550 off a car – 10% of the list price of a Cortina 1.6 L. This meant that combined with dealer mark-up, a discount of up to 30% could be obtained, which meant that you could have a Cortina Ghia on your drive for the price of a base Sierra. Customers wanted the future, but were swayed by the price of the past, and the blue oval’s army of smooth-talking sales people. Ultimately there was just too many un-sold Cortinas stockpiled throughout 1982 and into ’83.
Ford panicked, and worried that its precious 30% market share of the British market was vanishing, and introduced the Orion a booted Escort as a less-than-subtle nod to those conservative buyers who couldn’t get into bed with the Sierra, and were tempted to go knocking on Vauxhall’s door with its ultra-successful second-generation front-wheel drive Cavalier.
Come 1987, though, and Ford grew the Sierra family, finally giving the sale rep the saloon that he knew he always wanted. The Aeroback was finally to be joined by the Sapphire.
From Aeroback to Notchback
February 1987 saw the UK launch of the Sierra Sapphire. The slightly twee new name was give to denote the three-box Sierra, and ushered in the arrival of the facelifted hatch and estate models.
Visually just a little smoother, the new cars featured over 77 new or altered body stampings, and were enough to give the Sierra a more palatable style that drew it close to the range-topping Scorpio model. The big difference between the hatch and saloon was the boot and bonded rear windscreen (one of the major technical advances that rival Austin-Rover had perfected three years previously at Cowley). Looking a little closer, the roof (a nod to the second generation Astra/Kadett) sported intergrated flush drip rails, and the overall length grew by 40mm. Implementing these changes cost Ford a cool £228m.
A nod to Britain’s conservative buyers, saw one unusual change to the Sapphire model – a radiator grille. A bonnet 50mm shorter meant a pseudo plastic grille was fitted, easily differentiating the two cars in the motorway overtaking lane. Interestingly no other European followed suit with this largely pointless demarcation. In total, over 1200 new parts were required for the facelift, mainly electrical, with electronic engine management and electronic Teves ABS available, filtered down from the Scorpio’s introduction (as was the Triplex heated front windscreen). Security was upped with the introduction of six-lever Chubb locks to deter car thieves and appease insurance groupings. Further technological advances would be announced in November 1987, with the launch of the notch bodied Cosworth…
For the 1988 model year, Ford dropped the weak performing 1800 Pinto in E-Max tune in lieu of a new 1796cc CVH engine, which was coded the R2A engine. This new alloy head engine featured novel ideas such as hydraulic tappets with rollers to prevent excessive wear of the camshaft, longer service interval requirements and a water heated inlet manifold/carburettor promising good fuel economy.
The physical size of the engine was much smaller that the Pinto unit it replaced. Routine servicing was a breeze and as a result, the engine was considerably lighter than its predecessor thus loosing its nose heavy feel in hard cornering. The engine was quieter, more powerful and had a reasonable turn of speed. Soon after launch, demand outstripped supply from both fleet and retail customers. Vauxhall and Austin Rover had moved the goal posts in the engineering stakes and Ford now had a product to go to battle with.But Ford didn’t stop there…
The 1989 model year saw the end of the 2-litre Pinto units in the Sierra with the launch of an all new alloy head twin cam engine available in twin choke carburettor and fuel injected guise. Although the old single cam engine was utterly reliable and well known world over for being a robust power unit, Ford had slipped behind the competition in the power stakes with Vauxhall’s Family Two and Austin Rover’s 16-valve M-Series engine. Both trade and retail customers were demanding technology and performance, no longer was the family car seen simply as a repmobile and packhorse.
Carrying on in the Ford tradition of a crossflow design, this new power unit was a twin cam engine but having only the traditional eight valves. A whole new adaptive and diagnostic engine management system kept the engine in tune and peak performance with minimal attention while all routine servicing was simple to undertake, keeping the time in the service bays to a minimum.Ford’s Diesel Dilemma
In the late 1980s Ford also took the opportunity to ditch the harsh and unrefined 2.3 litre Peugeot-sourced diesel engine and replaced it with its own 1.8-litre Endura D unit as fitted to the Fiesta, Escort and Orion. In the Sierra however, it was only offered in turbocharged form. While no match for the Peugeot 405 and Citroen BX for performance or even economy, it was nevertheless light years ahead from the Sierra’s old pushrod 2304cc oil burner. Within 18 months, Ford had offered a bundle of new engines to keep the Sierra in the top ten sales chart – and the strategy had worked a treat.
Some revitalised models came into stream fro the 1990 model year, namely the two repmobile specials, the upgraded LX and GLX. The former was identified by its two-tone paint job and neat boot spoiler. In keeping with a constant programme of modifications, the Sierra was treated to little revisions such as lowered ride and tighter bushes to make the car feel nimble on its feet. Interior wise, the classic ‘wrap round cockpit’ stayed pretty much the same albeit with a new chunky steering wheel with adjustment for reach as well as rake.
Ford knew that by the early ’90s, the Sierra was living on borrowed time, so a massive advertising push was given in order to raise the profile of the Ford portfolio. Riding on the back of massive motor sport success with the ever conquering Sierra RS Cosworths, Ford teamed up with Queen lead guitarist Brian May, who slightly altered the wording of a not so well-known album track, Driven By You. The advertising slogan Everything We Do Is Driven By You soon became a virtual household phrase thanks to an epic one minute TV commercial, and all new Ford cars sporting that slogan in their rear window.
The Mondeo was in the pipeline, but owing to the ever improving opposition, Ford’s market share was at risk. Between 1991 and the final Sierras hitting the showroom in 1993, a series of steady improvements and revisions tastefully executed made sure that it remained in the public eye and on the road. To keep production costs down, Ford changed the dashboard and used a cheaper, but better looking, one-piece moulding. More importantly, during the crime-ridden early ’90s, security systems were added across the range. In the looks department, a subtle new grille and colour-coded bumpers were added across the range, along with some run out special editions called the Azura, Chasseur and Quartz.
So in all, Ford knew what it was doing in the marketing department. Until the very end, the Sierra held its own in the top ten league remaining popular to its demise with very few unsold examples lingering in stock after the launch of the Mondeo.Sierra in service
As far as engineering and reliability were concerned, the Sierra was a good solid car right from the outset. The powertrains and gearboxes were carried over in modified form from the Cortina giving no headaches to the workshop staff or fleet manager. Its simple all round independent suspension was simple yet well designed, only the track control or compliance bushes being a weak link.
The Sierra was an expensive car to design and Ford made some silly mistakes as the company bean counters looked at ways of saving money. From mid-1986 to late-1987 Ford decided to assemble its body shells using panels of recycled steel. Stories of door skins and wings simply rotting away within two years were no myth and this affected all Ford cars and light commercials around this time. These cars were known within the motor trade as ‘D-for-doom’, referring to rusty D-reg cars that were common place. This penny pinching act went on to cost the company millions in warranty claims.
Moving on to the late ’80s and early ’90s, Ford’s later power units were not exactly top notch either. The 1.8-litre CVH engine that was unique to the Sierra was having massive problems with oil consumption owing to a poor design of valve stem seals. It was very common to see these cars leaving a trail of blue smoke behind. Other issues with this engine were poor quality pistons resulting in small end failure and eventual total engine destruction.
The 1.8-litre unit soon developed into a decent engine thanks to modifications in service, the big problems came with the larger 2.0-litre twin-cam engine. Premature timing chain failure, timing gear problems, cracked exhaust manifolds, spark plugs seizing into the cylinder head and even head gasket failure dogged the twin-cam unit. Where the 1.8 became good, the 2-litre fast became known for being fragile and troublesome. Fitted to the 2-litre was a new gearbox known as the MTX. This alloy-cased all-syncro gearbox was far from being as sweet-changing and durable, as the N-Series Cortina-derived gearbox it replaced.
Where Ford tried to make an impact with new technology, it lost out on reliability. Aggressive marketing and heavy discounts kept the Sierra in the frame, but in its last year of production Vauxhall was chipping away at Ford’s fleet market share with its MK3 Cavalier. Ford rode out the problems by teasing the public with the launch of the Mondeo quite a while before it was launched, thus deflecting criticism of the old car by exiting everybody with the up and coming new models.
The Sierra gave way to the Ford Mondeo in 1993, and after what seemed an eternity in production of what in fact was just over 11 years, the new front drive world-beater from Ford soon turned the image of the Sierra from a car for all people into an also-ran used second hand bargain. Numbers still left in daily use are fast dwindling but the Ford Sierra will always be known by one of its early advertising slogans….
Man And Machine… In Perfect Harmony
Ford Sierra (1982 – 1993) Buying Guide
- All-independently sprung successor to the Cortina, sold as 'man and machine in perfect harmony'.
- 14' 5" long by 5' 6" wide and weighing 969kg to 1194kg.
- Estates were 14' 9" long and saloons (called Sapphires, from March 1987) 14' 8" long.
- Multitude of different engine, gearbox, drive system and trim combinations, including a rare three-door hatchback with 1.3 and 1.6 engines also used for the Sierra Cosworth.
- 1294cc CVH had 60bhp; 1593cc Pinto had 73bhp; 1597cc CVH EMAX had 75bhp; 1796cc CVH had 89bhp; 1993cc single cam carb had 101bhp; 1993cc single cam injection had 115bhp; 1998cc twin cam carb from August 1989 had 107bhp; 1998cc twin cam injection had 123 to 125 bhp.
- Early 1993cc twin-cam rear drive Cosworth Turbos had 204bhp; later 4x4s had 220bhp in standard tune; 2933cc V6 had 150bhp.
- Early 2.0 litre four-speed versions were fast cars in their day with 9-second 0-60 and 120mph max.
- Last of the line 124bhp GT was a good run-out model.
- Cats can legally be removed from J-reg.
- XR4x4s had Cosworth four wheel drive system with 125bhp four or 150bhp V6.
- A lot of enthusiasm for 2.8 and 2.9 4x4s and, of course, all Cosworths.
- A good pre-cat Sierra should be cheaper to run than an early catted Mondeo.
- Front suspension wears out and makes it terrible to drive. Cured by polyurethene reaction arm bushes. (In the early 1990s, Sierras were one of the few cars better bought after accident repairs to the front which could make them feel new again.)
- Most are now scrapped.
- Survivors are getting old and tired and were never supposed to last 10 years-plus.
- On very early cars a small knock at the front could crumple the transmission tunnel, severely weakening the shell.
- Many have done huge mileages and the clocks may not be showing it.
- If 1.8 CVH engine cuts out the reason is usually wear to the fuel pump pushrod at the camshaft end. To check this, remove the fuel-pump and withdraw the pushrod. There should be a slight bevel on both ends but in most cases one end will be square across. It only needs to have worn by 2-3mm to cause problems.
- Check for every single trick in the book. Clockers. Cloners. Cut 'n' Shuts.
- Rust traps in doors (cured on later cars).
- Warped front discs.
- Cracked heads and oil leaks on two litre twin-cams.
- If the steering feels unusually horrible the front suspension reaction arm bushes have gone.
- Treat all 4x4s and Cosworths with particular suspicion. Check their history with the club. 4x4s are apt to snap the front transfer case to final drive driveshaft.
- This is just the tip of the iceberg, so check everything.
