Lancia Stratos Concept

Lancia Stratos Concept

The legendary Lancia Stratos HF was without a doubt the most spectacular and successful rally car of the 70s. With its thrilling lines and uncompromising design tailored to rally use, the Lancia Stratos not only single-handedly rewrote the history of rallying, it won a permanent place in the hearts of its countless fans with its dramatic performance on the world's asphalt and gravel tracks - a performance which included three successive world championship titles.

For Michael Stoschek, a collector and driver of historic racing cars, as well as a successful entrepreneur in the automotive supply industry, the development and construction of a modern version of the Lancia Stratos represents the fulfillment of a long-held dream. Back in 2003, the dream had already begun to take on a concrete form; now, at last, it has become a reality.

In November 2010, forty years after the Stratos' presentation at the Turin Motor Show, the New Stratos was publicly presented for the first time at the Paul Ricard Circuit - the legend returns.

The project initiators.

The contemporary New Stratos is a non-commercial project by Michael Stoschek and his son Maximilian Stoschek. Together, they played a fundamental role in determining the technical concept and design of the one-off vehicle. Construction of the car has been underway since autumn 2008, at Pininfarina in Turin, Italy.

Michael Stoschek is chairman of the Brose Group. Brose is the fifth-largest family-owned company among global automotive suppliers.

A keen sportsman, Stoschek won the Carrera Panamericana in 1999, 2001 and 2004, and the 2006 FIA European Rally Championship, driving a 1971 Porsche 911 in both races. The Lancia Stratos Group 4 has a special place amongst the historic rally cars that Stoschek employs for rallies and hillclimbing. Sporting a Marlboro design, the vehicle has been restored over more than a decade, according to the specifications of the 1974 Tour de Corse Andruet/Biche works car.

The decision to develop and build a new, ready-to-run Stratos was inspired by a meeting with Chris Hrabalek, with whom Michael Stoschek became acquainted at the 1986 World Stratos meeting organized in Alta Badia by Stoschek. This was also the impetus behind Stoschek's involvement in the Fenomenon Stratos project, presented at the 2005 Geneva Motor Show, as well as his co-acquisition of the Stratos trademark rights.

In September 2008, Michael and his son Maximilian Stoschek commissioned Pininfarina to build a one-off vehicle. Currently, the New Stratos is one of a kind. Michael and Maximilian Stoschek hold all rights to the vehicle as well as ownership of the tools. Production of an exclusive, limited run under their license is planned.

Engineering the New Stratos.

The goal for the development of the Lancia Stratos HF's successor was to once again create a mid-engine sports car with a short wheelbase, low weight and superior agility.

Just as the Lancia Stratos, with its Ferrari Dino V6 engine, was nevertheless a distinct sports car in its own right, the New Stratos is also a distinct development, using components of the Ferrari 430 Scuderia. Almost all of these components have been modified and, as necessary, customized to their new purpose. However, it should also be emphasized that the Ferrari Scuderia already sets the standard amongst the current super sports cars and, as such, provides an excellent basis for further development.

The aluminum chassis was shortened by 20cm and welded to a roll cage made of 40mm-thick FIA FE45 steel. This method significantly increases rigidity, and this, combined with the shifting of the center of gravity towards the front, provides the basis for the vehicle's extraordinary handling characteristics. Both the body - which is 33cm shorter than the Scuderia's - and the interior are constructed entirely of carbon fiber and aluminum. All of the body components of the shell and interior are made of visible carbon. This places especially high demands on the quality of the processing, which was accomplished by Re Fraschini.

The centerpiece of the New Stratos is the 4.3L, light alloy V8 engine from the Ferrari F430 Scuderia, which accelerates the high tech sports car to a speed of 200 km/h in 9.7 seconds. The high performance engine which draws its intake air from the roof spoiler's side openings, has been equipped with a new control unit and a high-performance exhaust system by Capristo, including manifold and sports cat exhaust system; it delivers 540 hp and provides a torque of over 500 Nm.

The sequential 6-speed transmission received a new mechanical Drexler differential lock, and the modified control electronics now allow for extremely fast gear changes.

The chassis was completely reengineered by the ZF Sachs engineers, including integration of new electronic damper calibration, adjustable via the steering wheel, modified springs and optimized camber and toe values. The 9 and 11-inch wide by 19-inch center lock wheels are fitted with Dunlop Sport Maxx tires, sizes 265/30/19 and 315/30/19.

To fully reap the benefits of the lightweight, torsionally stiff, well-balanced vehicle, the height, camber, toe and caster were changed completely, and, above all, the whole setup.

To this end, stiffer suspension springs were employed alongside new damper calibration with greater differentiation of damper stiffness, adjustable via the steering wheel, as well as an optimum wheel/tire combination identified via testing of various tire brands, sizes and rubber

The performance.

The New Stratos, like the racing version of its predecessor, has been extensively geared - down to every last detail - towards lightweight design and performance. Not surprisingly, the specification sheet was therefore extremely ambitious in this regard as well.

The low vehicle weight, the excellent balance and the precision chassis components made possible by the rigid body, were intended not only to provide an exhilarating driving experience, but to provide measurable results in the form of objective data.

As work on the New Stratos continued virtually without pause up until the presentation in Le Castellet, and weather conditions offered no opportunity for performance test runs, these will have be carried out at the next available opportunity.

We expect a power-to-weight ratio below 2.3 kg/hp with an acceleration time from 0-100 km/h of 3.3 seconds and from 0-200 km/h of 9.7 seconds. We expect top marks for braking performance and a benchmark position in the 18- and 36-meter slalom and similar handling tests.

After introducing the new rear axle ratio (crown wheel and pinion 9/45), the top speed will be reduced to 274 km/h, in order to achieve even better acceleration values.
