The future of F1

Renault just released some new material to show us a vision of the future of the Formula 1. Renault is not a new comer in F1 and this year is the 60th anniversary of the Etoile Filante.

60th anniversary Etoile Filante and Renault Dauphine at Bonneville

The Renault Étoile Filante (Shooting Star) was Renault’s only attempt at both creating a gas turbine-powered car and setting a land speed record for such cars. In 1954 the French aeronautical turbine’s manufacturer, Turbomeca, proposed that Renault make a gas turbine car, both to exalt the benefits of the technology and to try to break the speed record for gas turbine cars.

Renault created the car, and tested it in a wind tunnel between 1954 and 1955. In 1956, Jean Hébert and a Renault Team went off to the Bonneville Salt Flats in Utah for speed tests. The car reached an average speed of 191.0 mph (307.4 km/h), achieving a world record for turbine-engine cars.

  • 306,9 km/h on one kilometre
  • 307,7 km/h on one mile
  • 308,85 km/h on five kilometres
  • 280,8 km/h on five miles

60 years of innovation

In the same spirit as the Étoile Filante, Renault’s avant-garde vision for the future of Formula 1 seeks to foster innovations that also inspire the designers of its upcoming road cars.

The new R.S. 2017 Vision is the fruit of 60 years of research, development and racing.

Renault is backed by 40 years of success in Formula 1

Renault sees motorsport as a formidable opportunity for the development of cutting-edge technologies that go on to benefit its road vehicles, either directly or indirectly.

Since its Formula 1 debut in 1977, Renault has consistently played an important role in the sport, pioneering ambitious, avant-garde technologies fuelled by its passion.

  • The V6 turbo engine that powered the Renault RS01 in 1977 sparked a revolution in its day and went on to feature twin-turbo technology from 1979.
  • The introduction of air valves in 1986 enabled engine speeds to be increased with no detriment to reliability.
  • In the 1990s, gear-driven camshafts led to higher-revving engines.
  • Direct fuel injection appeared in 1995 (Renault RS7 engine) to optimise intake efficiency and fuel consumption.

The heritage of all these revolutionary innovations is still visible in today’s Formula 1 with the return of the V6 turbo –in hybrid form– in 2014. By meeting the challenge of the new regulations, Renault has contributed its extensive expertise and skills as an F1 engine supplier to boost technological innovation, an invaluable asset when it comes to the brand’s upcoming road models.

A Formula 1 record that commands respect

  • Renault has been active in Formula 1 for almost 40 years. In addition to racing as a team, it has also been an engine supplier to the sport’s leading teams over the years, harvesting no fewer than 12 Constructors’ world titles and 11 Drivers’ crowns in total (see complete list below).
  • Renault left an indelible mark on each era of its involvement as a team: 1977 to 1985 (V6 turbo), notably with Alain Prost.
    2002 to 2010 (normally-aspirated V10 and V8), notably with Fernando Alonso.
  • Return of Renault to Formula 1 in 2016 as Renault Sport Formula One Team for its third time as a manufacturer.

The R.S. Vision concept car

The R.S. 2027 Vision concept carries over some of the classic attributes of Renault’s very first Formula 1 car – the RS01 from 1977 – such as its V6 turbocharged engine. Elements like its peripheral rear wing and livery provide similar flashbacks.

Like the Espace F1 in the mid-1990s, the R.S. 2027 Vision comes in Renault Sport’s traditional yellow-and-black Formula 1 colour scheme. In this case, the colors are embellished with a metallic finish that enhances the car’s visual appeal. The yellow particularly stands out for its gold leaf effect embodying quality, technological prowess and high performance.
The R.S. 2027 Vision concept not only seeks to pay tribute to four decades of Renault dedication, innovation and success in Formula 1, but also underlines a strong commitment to the future.

  • It shows how the passion that drives the brand also applies to its Motorsport activities, resulting in the development of major technological innovations.
  • This technology –and the specific design elements born of it– is clearly visible in the concept.
  • Everything about the R.S. 2027 Vision has been conceived to optimize performance and enhance the entertainment value of Formula 1.

In Renault’s ‘Cycle of Life’ design strategy, the R.S. 2027 Vision embodies the “play” petal.

F1 updated

With the new concept car, Renault brings some new ideas.

In terms of design, Formula 1 evolves to become equally appealing to racing enthusiasts while it attracts new fans.

  • Active LED lighting incorporated into the wheels displays a range of information, including the driver’s position and the car’s remaining energy reserves, making it easier for spectators and television viewers alike to understand how the race unfolds.
  • Some of the driver’s telemetry data is accessible to fans via the Internet, enhancing their overall understanding of the race and the strategy. This data also allows connected players to participate real-time in the race and compete against their heroes.
  • In addition to the roles they play in optimizing performance and energy efficiency, the combination of mobile aerodynamic features and active lighting systems make the cars more ‘communicative’ for spectators and television viewers.
  • To make the show even more captivating for spectators, the colour emitted by the lights switches from a white to a blue hue when the electric mode is activated.

With an innovative transparent cockpit, the R.S. 2027 Vision concept provides the best-ever view of the driver at work. This resistant, lightweight shell is 3D-printed, with forms tailored to the driver’s body, mirroring how the design of Renault’s road-going models is directly inspired by the human body.

Safety in F1

Numerous decisions have been taken to make the discipline even safer for all involved, notably the drivers.

  • The F1 cars incorporate autonomous driving functions. This delegation of driving duties is automatically activated in the situation of race incidents (safety car, virtual safety car, yellow flags, etc.). In this situation, the mandatory single-file running and accompanying restrictions (ban on overtaking, speed limits, etc.) are managed entirely by the car, minimising the risk of further accidents and ensuring the safety of competitors and track marshals alike.
  • The car’s closed cockpit protects the driver from flying debris and other dangerous objects that have the potential to strike with force. This aerodynamic canopy has been produced in polycarbonate, which is ultra- resistant to impact and flames.
  • It is framed by two titanium ‘pop-up’ roll-over bars that emerge from their unobtrusive location in milliseconds should the car overturn, providing the driver –still strapped into the seat– with an essential gap between the cockpit and the ground from which to escape.
  • These two features were both specifically designed to allow the driver to be able to extract himself from his car in the event of an accident in which their car overturns, and not to hamper the efforts of rescue teams if required.

Safety is similarly ensured by the ultra-connected nature of these Formula 1 cars –increasingly common features across Renault’s passenger car range. These functions exchange information based on what is happening in the race, seamlessly.

  • Vehicle-to-vehicle (V2V) communication with the other cars in the race, so that every driver knows exactly where each of their competitors is on the track or in the pit-lane. This feeds information to the pit lane’s predictive collision warning system, preventing teams from releasing a driver while another car is passing by at speed.
  • Vehicle-to-Everything (V2X) communication with peripheral systems on the steering wheel’s digital screen, including the immediate display of instructions given by the race director, such as yellow or blue flags. A direct link is established with the marshals in the section of the track where each car is running.

In Renault’s 2027 vision, Formula 1 also focuses on sustainable technology and systems to gradually reduce its ‘carbon footprint.’

  • Designing the individual parts of a Formula 1 car now requires less time and tooling thanks to increasing use of 3D-printing. This benefits the R.S. 2027 Vision concept as it previously benefited TREZOR, the Renault concept car unveiled at the 2016 Paris Motor Show that formally launched the brand’s new design cycle.
  • The new materials used by 3D printers to produce parts are more recycling-friendly than many composite materials they replace.

These decisions serve to make the cars both safer and cleaner, without detracting from the spirit of single- seater racing.

higher-performance cars for more entertaining racing

To put the human factor back on centre stage, Renault’s vision for Formula 1 in 2027 also covers the technical side. In addition to delivering higher performance, cars have taken advantage of the new electrification technologies to become even more efficient. Consequently, they contribute to making Formula 1 a continued test ground for passenger vehicles while helping the race industry follow a responsible approach to costs.

Maintaining its role as a platform for Renault’s advanced technology, Formula 1 in 2027 drives innovation efforts towards higher engine and aerodynamic efficiency.

  • The total amount of power is 1 megawatt and the weight limited to 600 kilos.
  • The level of power generated by the Kinetic Energy Recovery System is now fixed at 500kW (compared with 120kW in 2017) courtesy of two ERS-K units, one at the front and one at the rear.
  • This four-wheel drive configuration delivers unprecedented traction for a single-seater racing car.
  • The car’s very high-energy density batteries, two times the current F1 batteries –a field of intensive research for Renault’s electric vehicles – are connected to an ultra-high-performance dual-energy recovery system. Thanks to two 250kW electric motors (one at the front, one at the rear), the bulk of the energy otherwise wasted under braking can be recovered and stored for later use during the same lap.
  • To minimise energy waste due to drag at high speeds without detracting from slow-speed stability, the car’s aerodynamics are now active. Their efficiency is further enhanced by active suspension that optimises handling under the exclusive control of the driver.
  • In addition to facilitating pit-lane manoeuvres, four-wheel steering makes the cars agile and responsive.

Many of these innovations enrich Renault’s technology know-how, some of which are already available in its current range of passenger vehicles, for example, Renault’s MULTI-SENSE system with active damping and the high-energy density batteries of Renault ZOE Z.E. 40.

Technology evolutions and performance objectives, while maintaining an energy efficiency goal, reach the balance between power output from the engine and power output from electric motors.

  • F1 hybrid power plants based on a V6 combustion engine incorporating downsizing technologies such as turbocharging and multipoint fuel injection, a configuration that maximises power output while curbing fuel consumption and volume.
  • The capacity of the fuel tank is just 60kg (compared with 105kg in F1 today), which is the quantity necessary for the shorter, more exciting race formats.
  • Meanwhile, high energy-capacity batteries, two times the current F1 batteries energy density –a similar level to the Formula E batteries that will be used in Season 5–, are used to power the two 250kW electric motors in a sustainable way. They also allow the car to be driven in all-electric mode to save fuel during certain moments of the race, such as the formation lap and entering and exiting the pits.

Renault’s vision of Formula 1 in 2027 also advocates for a responsible approach to costs. By capping expenditures, the discipline can attract more manufacturers and teams for a long-term commitment.

  • To achieve this, F1 benefits from standard elements, thereby reducing the economic pressure on the teams: all non-performance-differentiating components are provided by a single supplier selected by the FIA.
  • Restricting development work on the cars’ aerodynamics brings wind tunnel and parts production’s budgets down, too. Only the front and rear wings, engine cover, floor and diffuser can be remodelled, and only three configurations are authorised during a single season.
  • Finally, F1 takes note of more accessible technologies and recovers with a certain pragmatism. For example, ultra-complex hydraulic suspensions give way to simpler active suspensions, but which could recover the otherwise lost energy.

A financially level playing field injects an extra element of excitement into the season, granting all teams an equal opportunity to compete.

In response to television audience trends and shifts in broadcasting formats, Renault explores how
Formula 1 in 2027 could become a more compelling form of entertainment. So, the format of Grand Prix weekends has been revised to make them more diverse, with exciting new opportunities to promote the drivers:

  • Sunday’s centrepiece-race shortened (250 kilometres instead of approximately 300 today) and divided into
    two parts: a long race and a second, shorter sprint known as the ‘Final Sprint.’
  • A Rookie Night Race, featuring the teams’ reserve drivers and the drivers who are in their F1 rookie year, is organised on the Friday evening of race week, ahead of Saturday’s official practice.

With this vision, Renault is sending a powerful message to the sport’s fans about the continued excitement and innovation ahead in Formula 1 racing.

  • Renault is more than ever a key player in the world of Formula 1 and intends to remain so for at least ten more years.
  • Over the course of these ten years, motorsport-honed innovations will continue to be carried over to the brand’s passenger models both in the Renault Sport Cars range, as well as mainstream Renault vehicles.
