What Is 2015 World Series by Renault

Overview

The 2015 World Series by Renault marked a rebranding of the long-standing Formula Renault 3.5 Series, aiming to elevate its global profile and attract broader interest in single-seater racing. Organized by Renault Sport Technologies, the series combined high-performance open-wheel racing with support categories under a unified promotional banner.

This season emphasized cost-effective competition while maintaining technical relevance to higher-tier motorsport, such as Formula 1. The calendar focused exclusively on European circuits, aligning with F1 race weekends to increase visibility and media exposure.

• Rebranding Initiative: In 2015, Renault rebranded the Formula Renault 3.5 Series to the World Series by Renault to enhance its international appeal and marketing reach.
• Championship Structure: The series featured two main categories: Formula Renault 3.5 for single-seaters and Renault Sport Trophy for sports cars, creating a festival-style race weekend.
• Season Duration: The championship began on April 18, 2015, at the Nürburgring and concluded on October 4, 2015, at the Circuit de Barcelona-Catalunya.
• Race Format: Each event weekend included two Formula Renault 3.5 races and two Renault Sport Trophy races, totaling 17 races across seven rounds.
• Technical Specifications: The Formula Renault 3.5 cars used a 3.4L V8 engine producing 530 horsepower, capable of reaching speeds over 280 km/h (174 mph).

How It Works

The 2015 World Series by Renault operated as a multi-class racing series with distinct technical and competitive frameworks for its two primary categories. Each round was designed to maximize track time and entertainment value while supporting driver development.

• Formula Renault 3.5: This category featured open-wheel, single-seater cars with carbon-fiber monocoques and sequential gearboxes, serving as a key stepping stone to GP2 and Formula 1.
• Renault Sport Trophy: A GT-style support series using the Renault Sport R.S. 01, a rear-wheel-drive sports car with a 3.8L twin-turbo V6 engine producing 500 horsepower.
• Driver Eligibility: Competitors in Formula Renault 3.5 were typically young talents aged 17–25, many with backing from national motorsport federations or manufacturer programs.
• Scoring System: Points were awarded using the FIA standard (25-18-15-12-10-8-6-4-2-1) for the top 10 in each race, with an extra point for pole position and fastest lap.
• Event Integration: Rounds were held alongside select Formula 1 Grand Prix weekends, including Monaco and Hungary, to boost audience reach and media coverage.
• Team Participation: Ten teams competed in Formula Renault 3.5, including DAMS, Tech 1 Racing, and Arden International, each fielding two cars per entry.

Why It Matters

The 2015 World Series by Renault played a pivotal role in shaping junior motorsport and promoting Renault’s racing heritage. Though it didn’t achieve F1-level viewership, it provided crucial experience for future champions and demonstrated cost-effective, high-level competition.

• Talent Pipeline: The series served as a proving ground for drivers like Oliver Rowland, who later competed in Formula E and Super Formula.
• Manufacturer Showcase: Renault used the series to promote its Renault Sport division and reinforce its performance brand identity.
• Technical Innovation: The R.S. 01 in the Trophy class introduced advanced aerodynamics and safety features later adapted for production models.
• Global Exposure: By aligning with F1 events, the series reached an estimated 200 million TV viewers across broadcast partners.
• Cost Control: Renault implemented strict budget caps and spec components to keep entries affordable and competitive.
• Legacy: The 2015 season was the last under the World Series by Renault name; the series was discontinued after 2017 due to shifting motorsport priorities.

Despite its eventual discontinuation, the 2015 World Series by Renault remains a significant chapter in European single-seater racing, bridging grassroots talent and elite motorsport through structured, accessible competition.
