Among these designers was also Eberhard Schulz (Eberhard Shultz). This engineer-designer and aerodynamics specialist has worked in the Mercedes and Porsche. But fame, albeit in a narrow circle, he has brought his own brand of unusual supercars – Isdera.
A little about the founder
Schultz began his career in the late 60's in the company Mercedes-Benz. He participated in the drafting of the prototype C-111 (which deserves a separate story). In Car Series C-111 by Mercedes simulated an application of new technologies such as rotary-piston and diesel engines, the use of plastics in the bodywork elements. the doors were in the "gull wing" style distinctive feature of the C-111 cars. But these cars were far from even small-scale production.
1968 -1969 years. Erator GT / GTE
Failing to get management to start producing Mercedes solutions S-111, Schultz creates his first own creation – Erator GT. The car was created under the impression from the famous racing prototype Ford GT40, but still it can not be called a "clone" of the winner of Le Mans.
Schultz uses Erator design ideas that would later become the hallmark of his firm: no rear-view mirrors and the use of sophisticated periscope device type, as well as door-type "gull wing". In developing its car Schultz used the proven components and assemblies brands Porsche and Mercedes. The basis of design – strong tubular steel space frame, lightweight outer body panels of fiberglass and double wishbone front and rear independent suspension. Initially under the hood hiding carbureted 1.6 liter Volkswagen 1600 L capacity of 54 hp, which allowed the car weighing 780 kg to accelerate to 160 km / h.
During the year, the humble Volkswagen engine was replaced by a more powerful V-shaped 6-cylinder 2.3-liter engine from the Ford Taunus capacity of 108 hp Its top speed was 200 km / h. In 1969, the car, and the remainder in a single copy, the latter was subjected to modernization. Place of V6 Ford took the 5-liter V8 Mercedes 420 hp
The engine has a mechanical fuel injection system Bosch fuel, due to which the index model appeared the letter E (from the German Einspritzanlage – fuel injection). Under a suspension components and brakes have been strengthened. With such a powerful engine light car weighing 960 kg was able to overcome the barrier of the speed of 300 km / h, developing as a result of 315 km / h. Acceleration from 0 to 100 km / h took only 4 seconds.
After creating Erator Schultz he was finally noticed and in 1969 was invited to work in the company Porsche. There he participated in the development and modernization of the Porsche 928 of the legendary 911 model. At the same time, Schulz did not stop cooperation with the company Mercedes, and managed to draw a design wheels Pirelli companies (yes, the famous Italian producers 70s tires were planning to expand production and take the release of alloy wheels) and Ronal Turbo.
1978. Mercedes Schultz Studie CW311 Concept
In 1978, Schulz together with the tuning company B & B Automobiltechnik presented he developed a concept car Mercedes-Benz Studie CW 311 – the only car brand, created not in the company, but who had a right to a Mercedes emblem.
For many years, even working in the Porsche, Schultz had the idea of prototype development, worthy successor of traditions rooted in the concepts of the series C-111. But the higher management of the group considered it hopeless. However, this did not stop Schultz. On the Rights of the developer of the car he took the project itself.
1982. Founding Isdera Gmbh
Schultz became an entrepreneur and opened his own business, which he calls Isdera. Isdera name is an acronym for the German Ingenieurb? Ro f? R Styling Design und Racing (Design Bureau design and racing). Soaring eagle emblem of the brand has been selected.
1982. Isdera Spyder
The first model of the new company became Isdera Spyder 033i, which was presented to the public at the Geneva Motor Show 1982.
Realizing that with his low volume machines can be difficult in the case of repair, Eberhard Schulz applied in all their cars only units and components that are used in vehicles manufactured serially.
The car almost four-meter length and a height of a little more than a meter is a lightweight sports car with a tubular frame and fiberglass body open, independent double wishbones and located in the middle of the engine from the Volkswagen Golf volume of 1.8 liters and output of 136 hp With him sagregatirovana 5-speed manual.
Its top speed was 205 km / h and acceleration to "hundreds" have a light roadster weighing 900 kilograms – just 7.5 seconds. In 1985 there is an upgraded version of the Spyder 033-16, which has been used for the 2.3-liter inline 4-cylinder engine Daimler Benz M 102 E 23/2 185 hp With him potyazhelevshy 20 kg car accelerates to 100 km / h in 5.5 seconds and a top speed of 232 km / h.
The pinnacle of evolution was the introduction in 1987 Spyder 036i, equipped with 6-cylinder engine Daimler-Benz M 104.981 power of 228 hp The pair worked with him-5 manual transmission company ZF production. Its top speed of 960 kg is 262 km / h and acceleration to "hundreds" takes 5 seconds.
Total from 1982 to 1992 was built a total of 17 cars, and the ex-factory price of one of them in 1990 amounted to 199,500 marks.
1984. Isdera Imperator
In 1984 at the Geneva Motor Show debut Isdera Imperator 108i, which is prepared for series production Mercedes-Benz CW311. The car body is a tubular chassis with fiberglass body panels attached to it. To it were attached independent double wishbones front and rear wheels. Before the rear axle is located a five-liter V8 Mercedes-Benz M177 produces 235 hp (417 N? M), which sagregatirovana five-speed manual gearbox ZF.
Although not the most powerful engine, the lightweight (only 1 250 kg) Imperator 108i can accelerate to 262 km / h, and the first "hundred" is exchanged for 5.9 seconds. The car was equipped with leather seats with electric, air conditioning, an advanced high-end audio system.
Schultz realized that for the fantastic price of almost 380,000 grades, for which he offered his car, we need not only an extraordinary appearance with the doors of the "gull wing" and periscope instead of a rear-view mirror, and higher dynamic performance.
In 1985, the car gets a 5.5-liter Mercedes V8 engine rated at 300 hp Potyazhelevshy to 1 380 kg car is exchanged "hundreds" of 5.5 seconds and a top speed reached 277 km / h. In 1989, the "Emperor" received a new six-liter V8 engine power of 385 hp, the AMG prepared by minders, with which the vehicle could accelerate to 314 km / h.
In 1991, the upgraded machine. The main external changes in steel mirror instead of a periscope, the front headlights with electrolifts and derived sideways before the exhaust pipes of the rear axle. The machine equipped with a 330-strong "eight", with which it can accelerate to a speed of 292 km / h. Price 400 000 DM deterred buyers (eg Honda NSX was worth 00 marks 155), and the car was obsolete in the face of many competitors.
30 "Emperor" was released just a few years of production.
1993. Isdera Commendatore 112i
At the 1993 Frankfurt Motor Show, the company introduced a brand new supercar called Commendatore 112i. The car got its name in honor of the great Italian designer Enzo Ferrari, who had the nickname of "Commendatore" (in Italian – Commander). The development of the car Shultz has invested more than 4 million marks.
Such costs demanded the latest at the time the electronic control system, such as an aerodynamic brake (when you press the brake pedal, the rear spoiler was raised at a greater angle to create extra wind resistance and increase the load on the rear axle) and controlled depending on the suspension speed (to high speed car automatically lowers the ride height). Design of the car turned a dynamic and memorable: a long rear overhang, designed with an eye on the long-tailed le-mann Porsche 917, and in a streamlined front headlamps were formally incorporated on the Porsche 968.
Not without the usual type for Isdery doors "gull wing" and complement their two reclining up the engine compartment cover. Below them, nestled 6-liter V12, taken from the latest at the time of the famous Mercedes S600 W140 in the back. The powerful 408-hp engine is easily dispersed "Commander" up to 340 km / h and acceleration to "hundreds" took only 4.5 seconds.
Machine design familiar to Isdery: aluminum tubular frame, exterior body panels of fiberglass and Kevlar, the front and rear independent suspension. The car's weight was only 1 450 kg. It was supposed to start small-scale production car, the price of which amounted to 450 thousand dollars.
Unfortunately, these plans did not come true. The production model was never launched due to a lack of funding – was built only one showpiece. Only in 1999, the company was able to build a second sample, which was called Silver Arrow C112i in honor of the legendary "Silver Arrows" Mercedes.
Place 6-liter engine took monstrous 7-liter V12, collected minders AMG. 620-horsepower giant was sagregatirovan with 6-speed manual transmission, joking dispersing potyazhelevshy 200 kg Isderu to 370 km / h. Acceleration from zero to "hundreds" fell by a full second: 3.6 against 4.7 at the "Commander".
car price was 620,000 dollars. The car, like its predecessor, was built in a single copy, and bought by a businessman from Switzerland who wish to remain anonymous. In 2005 this car was sold on the internet auction site eBay for $ 3 million, but was unable to find a new owner willing to pay such a sum for the exclusive.
2006. Isdera Autobahnkurier 116i
To build such a car Schulz dreamed more than 20 years of car development was started in 1984. The design was made in the style of German cars 30-ies of the last century, and the main subject was the inspiration for the legendary Mercedes 540K, which by the standards of those years was inaccessible to competitors as regards progressivity.
Dimensions "heir" in 2006 were impressive: 5.6 meters long and 2 meters wide. Moreover, a greater length took a very long hood and the passenger compartment of the body in general took the Beetle, after polishing up his trim precious woods and fine dressing skin. Of course, not without motors and installation of air conditioning and high-end audio system. Under the hood hides two (!) 5-liter V8 from the Mercedes S-Klasse W126, arranged in tandem, for each other, which is a major difference from other twin-engine cars.
And the car was all-wheel drive front-engine drives the front axle and the engine located behind it – back. The total capacity of the power plant – 600 hp, which allows the vehicle to disperse the weight of more than 2.5 tonnes up to a speed of 240 km / h and acceleration to "hundreds" takes 8 seconds. The car is not produced in series – one copy is kept in the garage Schultz.
Soon Isdera firm ceased to exist. Eberhard Schultz focused on cooperation with German automotive companies such as BMW, Mercedes and Porsche.
– A large number of the number of issued Isdera cars were sold to the Middle East.
– Car Commedatore 112i present in the computer game Need For Speed II.
– All the years of its existence, by 74 Isdera vehicle was manufactured.
– Each car has a brand components and assemblies of machines that produce large batches. Because of this, for the solution to the problem of car owner can turn to specialized service Mercedes, Porsche and Volkswagen.
brand car production Isdera
In its early years, the company based in the small town of Leonberg, near Stuttgart. Each car is hand built by a small group of masters. The construction of each car was going to order, after the personal dialogue with the head of the company and lasted about six months. In 1992 he moved to a small factory in the town of Hildesheim, in Lower Saxony.
What is the "trick» Isdera?
1. The first German serial mid-engined supercar with a body made of composite materials.
2. periscopes system on the roof instead of the door mirrors.
3. Application of the doors "gull wing" type in almost all the cars the company's lineup.
4. The massive use of electronics to improve the car's aerodynamic properties.
5. Application of the scheme with two motors, arranged in tandem, one after another.
