Raffaele "Lello" Marciello (; born 17 December 1994) is a Swiss and Italian professional racing driver who currently competes in the FIA World Endurance Championship for BMW M Team WRT and the GT World Challenge Europe Endurance Cup for Rowe Racing.

Noted for his tall height, Marciello was FIA Formula 3 European champion in 2013, won in the GP2 Series and tested for Ferrari and Sauber in Formula One. He switched to GT racing in 2017 and soon became a Mercedes-AMG works driver, winning the GT World Challenge Europe (2018, 2022, 2023), the FIA GT World Cup (2019, 2023), the ADAC GT Masters (2022) and the Spa 24 Hours (2022). After joining BMW for 2024, Marciello made his LMDh debut in the FIA World Endurance Championship and won the Nürburgring 24 Hours (2025).

Early career

Karting Marciello debuted in karting in 2005 and raced in various European championships, working his way up from the junior ranks to progress through to the KF2 category by 2010.

Formula Abarth In 2010, Marciello graduated to single-seaters, racing in the newly launched Formula Abarth series in Italy for JD Motorsport. He won opening race at Misano and race at Varano and amassed another two podiums it brought him third place in standings. He and fellow Formula Abarth champion Brandon Maïsano also became members of the Ferrari Driver Academy.

Formula Three Marciello stepped up to Italian Formula Three Championship in 2011 and joined Prema Powerteam. He claimed wins at Misano and Adria and another four podiums, finishing third and losing rookie title to Michael Lewis, but overcoming Maïsano by seven points.

In 2012 Marciello continued his collaboration with Prema Powerteam into Formula 3 Euro Series. and the revived FIA European Formula Three Championship. In FIA F3, he finished second in the championship, with nine podiums including seven wins. In Euro Series, he finished third with ten podiums and six wins. In both championships, he scored more wins than anybody else.

Marciello remained in F3 for 2013, and emerged as a pre-season favourite following his impressive results in the previous year and dominant performances in pre-season testing. He ended up winning 13 races and claimed the title with a race to spare.

Toyota Racing Series During the 2012 off-season, Marciello competed in New Zealand-based Toyota Racing Series, taking ninth place in the championship with a win at Hampton Downs.

GP2 Series

Marciello had been looking to be driving in the GP2 Series or World Series by Renault for 2014 after testing both cars in Catalunya in October 2013.

On 20 January 2014, the Ferrari Driver Academy announced Marciello would be racing in GP2 in 2014. However, they did not confirm the team he would be competing with. On 18 February, it was announced he would be driving for the Racing Engineering team. Marciello achieved his first GP2 victory in a wet feature race at Spa-Francorchamps after an intense fight with Stoffel Vandoorne in the closing stages. Multiple errors and incidents plagued Marciello's season, as he only finished in the points on six occasions, but his win and three further podiums took him to eighth in the standings.

Going into the 2015 season, Marciello joined Trident Racing. Though he only qualified outside of the top ten once, Marciello took the same amount of podiums as in his rookie season and finished seventh overall. Nevertheless, he scored 99.1% of the team's points.

Marciello raced with Russian Time in the 2016 season. In a season dominated by Prema Racing, Marciello finished fourth in the standings thanks to consistent performances which yielded six podiums.

Formula One On 26 November 2014, Marciello made his Formula One debut behind the wheel of the Ferrari F14 T, during that day's post-season test at the Yas Marina Circuit. He set the second fastest time of the session, half a second adrift of Pascal Wehrlein in the Mercedes F1 W05 Hybrid.

On 31 December 2014, it was announced that Marciello had signed as test and reserve driver for the Sauber Formula One team for 2015. In January 2016, it was announced that Marciello had been dropped by Sauber and had split with the Ferrari Driver Academy for personal reasons.

Sportscar career 2017: First step into GT racing In 2017, Marciello ventured into the sportscar racing scene, driving a Mercedes-AMG GT3 for AKKA ASP in the Blancpain GT Series Endurance Cup and Blancpain GT Series Sprint Cup. The Italian impressed in his debut year, scoring two podiums in the Sprint and Endurance cups respectively. His highlight however came at the 24 Hours of Spa, where, having qualified on pole alongside teammates Edoardo Mortara and Michael Meadows, Marciello used up the maximum allowed driving time of 14 hours to help his team to finish third.

2018: Mercedes factory driver Ahead of the 2018 season, Mercedes-AMG added Marciello to their rank of Performance drivers, thus making him a fully-fledged factory driver. The season saw him returning to both the Endurance Cup and Sprint Cup series where, once again with AKKA ASP, he paired up with Meadows in the latter and drove alongside Tristan Vautier and Daniel Juncadella in the former. Marciello performed to a high level, taking second-placed finishes in the Endurance rounds at Silverstone and - after initially being awarded victory when a suspected technical non-compliance for the winning team caused them to be provisionally disqualified - Barcelona, which led him to a runner-up spot in the Endurance Cup. Having inherited the title at first, an appeal by the disqualified team stripped the accolade from Marciello, with the disqualification being converted into a fine. Meanwhile, wins at Budapest and the season finale at the Nürburgring alongside a slew of further podiums gave Marciello and Meadows the Sprint Cup title.

That year, Marciello also partook in all four rounds of the Intercontinental GT Challenge with Mercedes. He scored podiums at Bathurst and Spa, as well as taking a win at the Suzuka 10 Hours, the latter earning him the provisional championship lead, though a seventh place at Laguna Seca, a race in which Marciello damaged his car and received a drive-through penalty after a mistimed move on the WRT Audi of Sheldon van der Linde, set him back to third in the standings.

2019: Maiden Macau crown Continuing into a third season of the Endurance and Sprint series at AKKA ASP, Marciello would be partnered by Vincent Abril in both championships, with the pair being joined by Michael Meadows for the endurance rounds. In the Sprint Cup, Marciello was unable to defend his title, even if a win at Zandvoort and a pair of victories at the season finale in Hungary earned him and Abril third in the championship, one the pair battled for until the final race of the season. As well as this, the final victory at the Hungaroring guaranteed AKKA ASP the teams' title. Their campaign in the Endurance Cup proved less fortunate, as retirements in two races saw the Italian end up 25th overall.

Marciello took part in the FIA GT World Cup, held at the prestigious Guia Circuit in Macau, at the end of the year with Team GruppeM. Having taken pole position for the event the previous year, the Italian repeated said feat in 2019, before proceeding to control Saturday's qualification race and winning the main race, therefore becoming the GT World Cup winner for the first time.

2020: ADAC GT Masters debut

Despite a truncated year due to the outbreak of the COVID-19 pandemic, Mercedes would expand Marciello's full-time racing duties, with him not only driving for AKKA in the rebranded GT World Challenge Europe Endurance and Sprint cups, but also taking part in the ADAC GT Masters alongside Philip Ellis. That campaign proved to be largely anonymous, say for the final race at Oschersleben, where Marciello and Ellis took victory from pole position.

His campaign in the Endurance Cup would see more success than the previous year: partnering Felipe Fraga and silver-ranked Timur Boguslavskiy, Marciello and his team ended up fifth in the standings, having taken a pair of podiums at the start of the year before encountering brake issues at the 24 Hours of Spa which ended their championship challenge. In the Sprint Cup, Marciello helped Boguslavskiy towards wins at Misano and Barcelona, though he would finish third in the drivers' standings - one place behind the Russian, who himself ended up mere four points behind the title-winning duo of Dries Vanthoor and Charles Weerts - as he missed the round at Zandvoort due to his commitments at the 24 Hours of Nürburgring.

2021: Further victories in GTM and GTWC

Marciello remained in the ADAC GT Masters for 2021, this time driving at Mann-Filter Team Landgraf-HTP WWR together with Maximilian Buhk. The season began promisingly, as the duo converted pole to victory at the season opener in Oschersleben in a commanding performance. The team would score two further podiums during the first eight races of the season, which was enough to close the gap to just three points compared to the leading Land-Motorsport outfit of Ricardo Feller and Christopher Mies. However, a retirement at the Sachsenring owing to a crash caused by Albert Costa and a 30-second penalty which led to a finish outside of the points in Hockenheim put the title out of reach for Marciello and Buhk, who ended the season fourth overall.

Marciello also drove for the AKKA ASP Team in the SRO competitions, being joined by new Mercedes factory driver Jules Gounon on a full-time basis in the Endurance Cup and once again partnering Timur Boguslavskiy in the Sprint Cup. In the former series, Marciello and Gounon were able to mount a title charge, taking second places at Monza, a race which Marciello led during the opening stint, and at the Nürburgring, where the team ran in second for the majority of the contest. Additionally, Marciello scored a second successive pole position for the 24 Hours of Spa, though the team would retire due to damper failure. The points they lost in Belgium cost the outfit during the final round in Barcelona, where, despite taking victory alongside Felipe Fraga, Marciello and Gounon would miss out on the championship by four points. In the Sprint Cup, Marciello and Boguslavskiy scored four podiums but failed to win a race, leading to a third-placed finish in the drivers' standings.

Near the end of the year, Marciello confirmed that he would be switching to a Swiss racing licence from 2022 onwards, citing a lack of support from the governing body of Italian motorsport as the reason for his "overdue" switch.

2022: GTM and Endurance Cup titles

Team Landgraf and Marciello were reunited for the 2022 ADAC GT Masters season, with a variety of teammates accompanying the Italian across the season. A double podium to start the year off was swiftly followed by Marciello's first pole at the Red Bull Ring, one which he converted to third place in the race. Following that round, teammate Jonathan Aberdein was replaced by Lorenzo Ferrari, with personal issues between Marciello and the South African and a lack of pace from the latter being the speculated reasons for said decision. A disappointing event in Zandvoort was the result, though Marciello would bounce back at the Nürburgring, winning the opening race and finishing second on Sunday alongside fellow factory driver Maro Engel and taking the championship lead in the process. The Swiss driver was joined by Daniel Juncadella, another factory driver of the German brand, for the remaining three rounds, where he took three further podiums as well as two pole positions, which enabled him to clinch the title one race early at the Hockenheimring.
