Going through the memory of exclusive brands, among the first called “Ferrari”, “Maserati”, “Lamborghini”. An inimitable design, original technical solutions, enviable dynamic characteristics, unit production - these are what are behind the big names. We decided to turn to even more rare …

The Bugatti-EB 16.4 Veyron is the most powerful of the production cars. The Volkswagen brand was resurrected by the legendary brand - in 2001, a prototype was presented at an exhibition in Frankfurt, and this year, finally, production began. Rival "Bugatti" - a little-known coupe "Probe" of the Italian company "Pagani". This supercar debuted in 1999, and in 2003 received an engine of a larger volume and power.

EXPENSIVE WRAP

The new Bugatti, according to the creators, is a bridge between the past and the future. The team of Harmit Varkus from the Center of Excellence Design of the Volkswagen concern had the goal of making the car in the spirit of company traditions, but ultramodern in design and technical level. Already in the first drafts a sports car with unique dynamic forms was guessed. From the past, the new Bugatti took the classic two-tone coloring and the traditional shape of the grille. Short front and rear overhangs, a long base and rounded lines, panels behind the side windows that visually lengthen the car, air intakes protruding above the roof - all this emphasizes power and elegance. A name also came from history - in the 30s of the last century, Pierre Veyron won a series of beautiful victories at the sports “bugatti”.

A little over a decade ago, designer Horatio Pagani opened the Modena Design firm, intending to develop sports prototypes. In 1992, the Italian conceived the design of the car, which he wanted to call "Fangio" - in honor of the five-time champion of Formula 1. However, after the death of the great Argentinean, the newborn was dubbed the "Probe" - the wind blowing from the Andes. Of course, in comparison with Volkswagen specialists, the young company Pagani has few opportunities and experience. But nothing binds the designer imagination. Therefore, the "Probe" turned out to be attractive and not like any car. Original forms, a kind of lighting technology, unusually high-mounted mirrors resembling small horns. One exhaust system is worth it! Four pipes are assembled at the back in a round nozzle, similar to a part of a spaceship.

In the Bugatti interior, the designers managed to combine two, at first glance, opposing styles - the asceticism of a sports car with the elegance and comfort of a limousine. The shade of thin Alcantara leather is selected to match the body color. The instrument panel is made in the spirit of the past: in front of the driver’s eyes there is a large round speedometer, to the right and left of which are a couple of round dials. The center console, which is not overloaded with buttons and displays, also reminds of the pre-war “bugatti”: the clock and (tribute to the present!) High-end audio system and climate control are brought here. Speaking of music. When developing a car, they specifically turned to the Dieter Burmester company, which carefully selected the necessary equipment and the optimal location of the speakers.

The interior of the "Probes" also does not take chic and shine - expensive leather, polished aluminum, elegant design. However, in her cabin there is more from a racing car than from a representative limousine - a sports steering wheel, floor pedals, characteristic toggle switches, and profiled seats. The latter are made of light carbon fiber and lined with expensive leather - nubuck, and the Pagani emblem flaunts on the headrests. Carbon fiber and other elements - for example, the main parts of the dashboard, reminiscent of the shape of the eyelid, center console, door trim.

TASTY START

The main body parts of the Bugatti-EB 16.4 are carbon fiber reinforced with aluminum plates. The car turned out to be not only easy, but also safe - virtual and real crash tests proved that the panels and the power structure efficiently absorb energy upon impact. For the manufacture of the chassis, carbon fiber and other lightweight materials are also used. For example, many of the suspension elements made of forged aluminum, the wheel hubs are made of stainless steel, and the brake discs (by the way, the deceleration here is close to what the pilots of Formula 1 experience) are made of ceramic.

At the base of the Pagani body is a chrome-molybdenum steel frame, and carbon fiber is used for the exterior parts. Expensive and technologically advanced materials made it possible to make the body not only light but also rigid. Even with a roadster, torsional rigidity exceeds 18, 000 Nm / deg, which is considered a good indicator for closed cars, while the “Probes” coupe has this parameter even higher.

It is known that flaws in aerodynamics make themselves felt already at a speed of about 100 km / h - and when the speedometer needle exceeds 300? In wind tunnels, both reduced copies of cars and full-size samples were purged. The experts had two main tasks: to minimize the drag coefficient and to make the wind blowing around the machine work for stability and controllability.

The designers of both companies paid special attention to the movement of air under the car. The bottom in the middle was made flat for unhindered passage of the flow, and closer to the stern were placed diffusers, which created a vacuum and thereby increased downforce. This method of taming the air, called the ground effect, was first tested on machines of formula 1 more than three decades ago. Now, the creators of serial cars are gradually taking over their experience. The "Earth effect" brings good results: the total downforce on the "Probe" at a speed of 300 km / h is 500 kg.

The rear parts of the Pagani and Bugatti additionally load the aerodynamic elements located on the body, and in front the bumper serves as the main flow distributor. Specialists spent a lot of time adjusting the shape of the part to get the necessary downforce on the front axle and achieve neutral understeer.

WITH ONE AND TWO V

Of course, the engines of our fighters match the rest. Under the hood of the Pagani is a Mercedes-Benz engine modified by AMG.

The V-shaped 12-cylinder aluminum unit claims to be one of the largest in volume and powerful among passenger engines. To reduce the mass of the connecting rod and piston group and additional reliability, AMG used titanium connecting rods. In addition, especially for the "Probes", the company developed an original intake manifold.

But the sparkle of the Pagani engine fades next to the Bugatti unit - the creation of the Volkswagen group of motorists. The eight-liter 16-cylinder - while the only one of the serial passenger engines develops over 1000 liters. with. Achieving compactness and rigidity, we connected two narrow V-shaped "eights" at an angle of 90 °. Air (it is cooled by two intercoolers located above the engine) injects four turbochargers into the cylinders. In addition to them, direct injection of FSI fuel and regulated phases helps to obtain such high rates. The motor is controlled by an electronic high-speed system; on each "eight" are installed independent of each other processors, which are commanded by the central unit.

The layout of the “Pagani” and “Bugatti” are close: for better weight distribution, the engines are installed in the base in front of the rear axle. At the "Probe" an impressive torque from the motor is transmitted back through a two-disk clutch and a six-speed gearbox. Self-locking differential and electronic traction control help to realize engine power. By the way, the designers thought about the all-wheel drive version of the "Probes", but so far this idea has been implemented only on paper.
