BMW Zentrum: Z3 manufacturing plant in Spartanburg, USA.
After the legendary BMW roadster of the thirties and fifties, almost tree decades were to pass before the company revived its tradition of open sportscar construction. In the interim BMW had grown from a universally reputable but economically shaken establishment into a highly successful global operation. An astute model policy and distinguished creative and innovative achievements had ensured that, besides securing its success as a carmaker, BMW remained one of the few surviving motorcycle manufacturers in Europe to prosper, and was even able to revive its aero-engine production, once the company's core activity.
BMW Z1

BMW Z1
It was in this favourable climate that the idea of a new BMW Roadster germinated and matured. For the first time, the task of developing such a model was given to the fledgling BMW Technik, a subsidiary of BMW comprising around 60 specialists devoted to innovative technologies - a kind of hi-tech think tank.

In July 1986 a car was presented to the press which instantly sparked the interest of the motoring world by virtue of its unusual concept and striking appearance: it was the BMW Z1. Apart from its 170 bhp (125 kW) six-cylinder fuel-injected engine with drivetrain adopted from the 3 and 5 Series, the Z1 had virtually nothing in common with any other BMW production car. It was a completely new development, the result of a great deal of hard work and commitment, and constituted, as it were, the apprentice piece of the new development division. Initially, however, the car was regarded solely as a test bed and prototype without any firm prospect of going into production. Only after the Z1 had made its debut at the 1987 Frankfurt Motor Show and order requests began flooding in was the go-ahead given for series production.

For the first time in BMW's post-M1 history, a car had been constructed with a plastic body made up of individual panels. The strongly wedge-shaped body was attached to a selfsupporting steel structure with bonded plastic floor, a hotgalvanized monocoque frame. The lightweight roadster hood disappeared discreetly under a cover which blended harmoniously into the sleek, no-frills profile of the car. Bne of the Z1's striking features was its hydraulically retractable doors, which lent the hi-tech model an even greater stamp of exclusivity.

After 12 pre-production cars had been exhaustively tested over a period of two years, the first BMW Z1 Roadsters were finally ready for delivery to eagerly waiting buyers at the turn of 1988/89. Not only was this open two-seater a real headturner, its powerful and silky-smooth six-cyliner engine made for impressive driving performance to boot. A top speed of almost 230 km/h (142 mph) and 0 to 100 km/h (62 mph) spurt of less than 8 seconds, coupled with safe and sporty handling, made performance-oriented driving a special delight in the Z1. Yet for all its power, the Z1 got by on less than 10 litres/100 km (28 mpg). This car was justifiably regarded as the most modern roadster of its time.

The only fly in the ointment was the relatively high price at which this unusual, largely hand-built sportscar came. With a basic price tag of DM 80,000, the Z1 was only marginally cheaper than the BMW 735 iL in 1989. Yet by the end of production in autumn 1991 the Roadster had sold 8,000 units - a number which would preserve its rarity value for the future.
Even as the Z1 was coming off the production line, the engineers and designers at BMW were turning their minds to the creation of a completely new roadster for the nineties. Initial sketches were produced in mid-1989 which showed obvious resemblances to the new 3 Series now nearing production. Three independent development teams worked on the new roadster project, one of the most desirable jobs in the automotive sector. The aim was not simply to create a roadster which was suited for everyday utility and stood for driving pleasure in its purest form; the new model was also meant to perpetuate the memory of a long tradition of open sportscars from Munich.
BMW Z3

BMW Z3
In the end of design was selected which, with its elongated bonnet and side cooling grids, bridged the stylistic gap between the BMW 507 and the present, while its strikingly low-slung, broad, compact body embodied the classic roadster philosophy in clear, flowing lines. Drawing on the proven, modern technology of the current BMW 3 Series, the Z3 also sets standards in its class with regard to safety, comfort and ride quality.

The production of the new BMW Z3 Roadster marked an entirely new departure in the history of BMW. The Z3 is the first BMW to be built exclusively at BMW's American plant in Spartanburg, South Carolina. Special attention was devoted to manufacturing quality which, under the slogan "Made by BMW", had to fulfil every expectation associated with buying a BMW product.

The Z3 managed to create a stir long before it went into production, thanks to its role as special agent James Bond's means of transport in the box-office hit "Golden Eye". This exciting action film with its theme song by rock legend Thina Turner allowed the Z3 a public exposure rarely granted to a brand-new sportscar.

BMW's latest roadster model has been available with two engine variants since spring of 1996. Today, after sales of around 35,000 units, one can safely predict that the Z3 will go down as the most successful BMW sportscar in the company's history. The most affordable entry into the circle of BMW Roadster owners is offered by the version with a 1.8-litre twin-valve four-cylindre engine. 115 bhp (85 kW) ensure that the Z3 Roadster 1.8 is not wanting in power. With a top speed of well over 190 km/h (129 mph) and 0 to 100 km/h (62 mph) achievable in just 10.5 seconds, it delivers a true sportscar feel. For the more exacting driver, a Z3 1.9 variant with a hi-tech four-cylinder, four-valve engine delivering 140 bhp (103 kW) has also been available since the start of production. Both engines come with the latest in engine technology: an individual-control intake manifold (DISA), digital motor electronics (DME) and a valve drive with roller-type rocker arms. ABS, driver and passenger airbags and seatbelt pretensioners come as standard, ensuring a high degree of passive safety.

The Paris Motor Show in October 1996 saw the debut of a new Z3 version which will cause plenty of excitement among roadster fans as the open-air season approaches: the Z3 Roadster 2.8 with a six-cylindre engine. A direct descendant of the legendary 328, the 192 bhp (141 kW) delivered by this hi-tech four-valve unit will make for very impressive performance all round. Apart from a tom speed of almost 220 km/h (135 mph) and acceleration from standstill to 100 km/h (62 mph) in 7.1 seconds, the 2.8-litre engine offers outstanding flexibility and thus ideal conditions for supremely smooth motoring.

Even with the arrival of this sporty, elegant and exclusive variant, the Z3 story is far from over. In parallel with the appearance of the Z3 Roadster 2.8 in the second quarter of 1997, BMW will be launching the ultimate driving machine in the shape of the M Roadster. First publicly unveiled at the Geneva Motor Show in spring of 1996, this truly definitive roadster will bear testimony to the state of the art and power potential of its class. Equipped with the thrilling and utterly roadworthy drive technology of the M3, the M Roadster will occupy an unchallenged position within the ranks of the super sportscars. Rarely in the course of motoring history have attributes such as agility, safety, compactness and nearinexhaustible power come in such attractive, authentic roadster packaging. The sheer power reserves of the 3.2-litre engine with 321 bhp (236 kW) peak output will transport the experienced driver into breathtaking realms of motoring experience, in the knowledge that the car is equipped with equally comprehesive safety features. Even in terms of environmental compatibility, the M Roadster - its massive power notwithstanding - creates a benchmark with its remarkably low fuel consumption figures.

Looking back on the succession of BMW Roadsters from today's vantage point, it quickly becomes obvious why this type of car has always yielded extraordinary results at BMW. Each car in its own right symbolizes the quintessential aim of the company, namely to provide driving pleasure in its purest form. And what type of car could be better suited to that task than the roadster, the epitome of exhilarating, sporty progress on four wheels?
