What Is 2015 Formula Renault 3.5 Series

Overview

The 2015 Formula Renault 3.5 Series was the final season of the championship before its rebranding into the Formula V8 3.5 Series in 2016. Organized by Renault Sport, the series functioned as a critical stepping stone for young drivers aspiring to reach Formula 1, offering high-level competition with professional teams and advanced machinery.

It featured a mix of experienced racers and rising talents competing across Europe, with circuits including Monza, Spa-Francorchamps, and Barcelona. The 2015 season marked the end of an era, as Renault shifted focus toward other motorsport initiatives, leaving a legacy of developing future F1 drivers like Kevin Magnussen and Carlos Sainz Jr.

• Oliver Rowland clinched the drivers' title with 205 points, securing four race wins and six podiums throughout the season.
• The championship kicked off on April 18, 2015, at the Nürburgring in Germany and concluded on October 4 in Barcelona, Spain.
• DAMS won the teams' championship with a total of 358 points, outperforming rivals such as Arden and Zeta Corse.
• The series used Tatuus FR3.5 chassis powered by a 3.5L V8 engine producing around 530 horsepower.
• Each race weekend featured two races: one after qualifying and another with a reverse-grid format for top finishers.

How It Works

The Formula Renault 3.5 Series operated as a single-make racing series, meaning all teams used identical chassis and engines to ensure competition focused on driver skill and team strategy. The 2015 season followed a structured calendar with events supporting major European motorsport series, including the World Series by Renault.

• Qualifying Format: A single 30-minute session determined the grid for Race 1; the top eight finishers in Race 1 were reversed for Race 2’s start. This encouraged aggressive racing and strategic positioning.
• Scoring System: Points were awarded down to 10th place, with 25 for a win, 18 for second, and 15 for third, mirroring FIA standards to align with higher-tier series.
• Car Specifications: The Tatuus FR3.5 featured a carbon-fiber monocoque, sequential gearbox, and 530 hp from a naturally aspirated V8 engine.
• Driver Eligibility: Competitors needed an FIA Super License or equivalent, ensuring only professionally trained racers entered the grid.
• Team Structure: Each team fielded two cars, with technical support from Renault Sport and strict parity rules to prevent performance advantages.
• Race Weekend Format: Events spanned three days, including practice, qualifying, and two races, each lasting approximately 45 minutes plus one lap.

Comparison at a Glance

Below is a comparison of the 2015 Formula Renault 3.5 Series with other major single-seater feeder series:

The 2015 Formula Renault 3.5 Series stood out for its powerful engine and direct link to Renault’s motorsport development pipeline. While GP2 offered closer ties to F1, the FR3.5 provided more affordable access to high-speed racing, making it a preferred choice for drivers without factory backing.

Why It Matters

The 2015 season was pivotal as it marked the last year under the Renault banner before rebranding, highlighting its role in shaping future motorsport stars. Its influence extended beyond race results, impacting driver development, team operations, and engineering standards in junior formulae.

• Driver Development: Oliver Rowland later competed in Formula E and Super Formula, showcasing the series’ role in launching international careers.
• Technical Benchmark: The 3.5L V8 engine offered performance close to GP2, making it ideal for testing driver adaptability.
• Cost Efficiency: At €500,000 per season, it was more affordable than GP2, attracting independent teams and privateers.
• Global Exposure: Races were held alongside World Series by Renault events, giving drivers visibility to F1 scouts.
• Engineering Legacy: The Tatuus chassis influenced later junior formula designs, including those used in Formula Regional.
• Series Transition: The 2015 finale led to the 2016 rebrand as Formula V8 3.5, continuing the platform without Renault’s direct involvement.

The 2015 Formula Renault 3.5 Series remains a significant chapter in junior motorsport history, remembered for its competitive racing, technical relevance, and role in bridging the gap between lower formulae and elite categories like Formula 1.
