The Infiniti Prototype 9 is a stunning modern interpretation of a classic racer

Infiniti has revealed an all-electric, retro-inspired race car prototype, which will go on display at the 2017 Pebble Beach Concours d’Elegance.

The classic car show brings together 200 of the most pristine retro vehicles in the world, with the most historically accurate and well-maintained examples earning awards.

However, with thousands of people attending the day-long event in California, manufacturers often put unique prototypes on display, such as the Prototype 9 revealed by Infiniti.

Engineers at Nissan’s premium division worked on the after-hours project, which was designed to evoke memories of the “emerging era of Japanese motorsport” in the 1960s.

Its retro appearance was built using traditional methods, with panel beaters hammering the sheet metal into shape by hand. Meanwhile, the smooth shape, open cockpit and long bonnet are said to be inspired by aeronautical designs.

Despite the classic styling, Infiniti was keen to incorporate modern technology underneath and fitted a new electric powertrain. It uses a 30kWh high-voltage battery with a prototype electric motor, which it says has not yet been used on a production vehicle.

It makes 146bhp and 320Nm or torque, driving the rear wheels through a single-speed transmission.

Alfonso Albaisa, senior vice-president of global design at Infiniti, said: “The beautiful execution of Prototype 9 represents a combination of artistry, craftsmanship and commitment to a romantic notion of our heritage.

“It inspired our people to work on Prototype 9 in their own time – as they were completely invested in the project and the details and features originated with them. Prototype 9 has been a labour of love for many of us.”

The 2017 Pebble Beach Concours d’Elegance takes place on Sunday, August 20.
