Johannes Antonius "Jan"Lammers (born 2 June 1956) is a Dutchracecar driver, most notable for winning the1988 24 Hours of Le Mansworld endurance race, forSilk CutJaguar/TWR; after four seasons inFormula One racing, from 1979 through 1982, for the F1 teams ofShadow,ATS,Ensign andTheodore, respectively. After a world-record setting ten-year hiatus, Lammers made a brief Formula One comeback, for two races, with teamMarch in 1992. Aside from racing in these two of the highest leagues of global auto-sports, Lammers has raced in an exceptionally wide number of racing series and competitions, domestic and abroad, over four decades.

Later in life, Lammers became a team owner as well, first setting up his own Formula Opel Lotus team, Vitaal Racing, winning the EFDA Opel Lotus Euroseries with Peter Kox in 1989, then creating theRacing for Holland outfit that raced in sportscars class in 2001–2007. Between 2005 and 2009, he was the seatholder of theDutch A1 Grand Prix team. During his Racing for Holland days, Lammers combined racing and management duties to win the2002 and2003FIA Sportscar Championship.

One of the most versatile drivers in modern motor racing history, Lammers started in touring cars, to become the youngest Dutch champion in history in 1973 while repeating the act in 1976. He also raced in the EuropeanRenault 5 Turbo Cup, taking the 1983 and 1984 European titles. As a single-seater driver, his steps towardsFormula One include securing the title in the1978European Formula 3 Championship. He remains the only Dutch driver to have done so. At the zenith of his career inGroup C sports-prototypes, Lammers lifted the crown in the1992Japanese Sportscar Championship.

Lammers has further raced inFormula Ford,Formula 2,IndyCar racing,International F3000,Japanese F3000, theBritish Touring Car Championship (BTCC),BPR Global GT,FIA GT, theEuropean Le Mans Series, theIMSA SportsCar Championship, theAmerican Le Mans Series,Grand-Am, and theDakar Rally.

Guest appearances include theGrand Prix Masters for retired F1 drivers, theBMW M1 Procar Series, theDutch Supercar Challenge, theDubai 24 Hours andGulf 12 Hours endurance races, the VW Scirocco R-Cup and the Dutch domesticTulpenrallye.

In recent years, Lammers was an important figurehead / ambassador for reviving theDutch Formula One GP on the coastal dunes situatedZandvoort circuit, achieved since 2021.

Born in Zandvoort, Lammers grew up washing cars at the nearby school for advanced and anti-skid driving skills training, run by Dutch touring-car legendRob Slotemaker. Encouraged by Slotemaker, and while still under-age for a regular Dutch driving licence, the teenager nicknamed 'Jantje' ('Little John') was also hired to teach drivers on a private, closed track, how to safely recover a car from a skid situation. Having recognised Lammers' talent, Slotemaker set him up in aSimca Rallye 2 for the 7,500-9,000 guilder Group 1 production car class in the 1973 Dutch Touring Car Championship.^[1] At 16 years of age, Lammers won his first-ever car race and continued to take the season title in his rookie year, becoming the youngest Dutch national auto racing champion in history.

Two more years in the Simca followed in a revised 8,000-10,000 guilder class, Lammers taking four more wins in 1974 but narrowly missing out on a title repeat.^[2] Wins elude him in 1975 but his name has already been made.^[3] In 1976, he switched to an Opel Dealer Team Holland-run Opel Kadett GT/E to take his second Dutch title.^[4]

Dovetailing his 1976 touring-car campaign with a first season inFormula Ford, Lammers quickly realises his future is in single-seaters. Driving aCrosslé in the Benelux, German and European Championship, the touring-car boy wonder surprises everyone by grabbing pole position at his first race, winning at theJyllandring and Mengen and shining in the soaking wet finale of theFormula Ford Festival atBrands Hatch.^[5]

Stepping up with Hawke toFormula 3 in1977 proves to be a false dawn, as the Hawke proves no match for the Marches and the Ralts. For 1978, he switches to the Racing Team Holland outfit run byAlan Docking, with fellow future Formula 1 driverHuub Rothengatter and later Indy 500 winnerArie Luyendijk as his team mates. This is an inspired move as it leads to Lammers winning the1978 European Formula 3 Championship after a close battle with SwedeAnders Olofsson, while beating highly touted rivals such asAlain Prost,Nelson Piquet and Nigel Mansell. Lammers takes wins atZandvoort,Magny-Cours,Karlskoga and in the famous Lotteria race atMonza to lift the crown. At the time, leading British magazineAutosport predicts: "He just has to be a World Champion of the eighties."^[5]

Having received an offer from the worksMarchFormula 2 team, Lammers decides to jump the category to go straight intoFormula One withShadow in1979. He will make his single Formula 2 appearance in 1980, driving a March-BMW in his home race atZandvoort, where he retires from third place.^[5]

Lammers spent four seasons inFormula One, racing largely uncompetitive machinery and failing to score a World Championship point in any of his 41 appearances.^[6] He was considered talented, however; Lammers only narrowly missed out on the chance to joinFerrari in 1982 to replaceGilles Villeneuve, who was killed atZolder earlier in the year. The drive went toPatrick Tambay instead.

In1979, Lammers and fellow rookieElio de Angelis joined Shadow, but the team led by AmericanDon Nichols was close to shutting down; the pair failed to make an impact with a poor car, with de Angelis scoring the team's only points that year, coming in fourth place at Watkins Glen. Lammers' best result wasa ninth place in the Canadian GP. Both were invited byColin Chapman to test forLotus, withDe Angelis getting the job for1980; Lammers was unwilling to wait for Chapman's decision. Instead, he decided to sign for theGerman-owned ATS team.

The underfunded outfit handed Lammers the old D3 car while team leaderMarc Surer debuted with the newD4, but when Surer broke his legs in an accident, Lammers took the D4. He immediately qualified fourth on the grid at Long Beach but the car broke on the opening lap of the race.^[7] Other notable ATS performances included battlingJody Scheckter'sFerrari atZolder, and retiring from a points-scoring position atJarama. When Surer made a return to ATS, Lammers moved toEnsign. Meanwhile, his former teammateDe Angelis had a fine season at Lotus while Lammers failed to qualify the cumbersome Ensign on several occasions.

For1981, Lammers was invited for a test to becomeNelson Piquet's teammate atBrabham, but team principalBernie Ecclestone chose to go with Mexican pay driverHector Rebaque.^[5] Instead, Lammers rejoinedATS and performed well in the controversial non-championshipSouth African GP at Kyalami; he foughtDe Angelis for second place until being hit by brake problems. When SwedeSlim Borgudd arrived with healthy funding from pop bandABBA, Lammers was made to gave up his seat.

In1982, Lammers switched toTheodore but the team was largely underfunded. AtMonaco, Lammers' TY02 had to stay on nude rims for a day because the team did not have any tyres. Still seen as a natural talent, he was asked byRenault to replace the injuredProst atDetroit, only for the championship leader to recover in time. Lammers stepped back into the Theodore, but before the start of the first session, he was approached by Ferrari to replaceGilles Villeneuve fromZandvoort on. In a twist of fate, the Theodore's throttle stuck during the session, causing Lammers to hit the wall and break his thumb. As a result,Patrick Tambay signed the Ferrari contract.^[5] At Zandvoort, instead of driving the Ferrari, Lammers took part in his last Grand Prix beforeTommy Byrne took over the seat.

In late1985, Lammers was given a test byToleman atEstoril but with the team unable to get a tyre contract for 1986, plans for a Formula One return fell through. In 1989, another Formula One opportunity came to nothing when Lammers was asked by KenTyrrell to replaceMichele Alboreto, but the Dutchman decided to stick withTWR Jaguar, and Tyrrell signedJean Alesi instead.^[5]

Then in1992, Lammers made a surprise Formula One comeback when he stepped in atMarch for the final two races of the season – a full ten years after his initial final Grand Prix, a record career gap in Formula One. ReplacingKarl Wendlinger, Lammers lapped sixth fastest in wet free practice atSuzuka, before retiring from the race with a broken gearbox. AtAdelaide, he finished 12th. Looking set to continue with March in 1993, his Formula One ambitions received a blow when the team was denied an engine deal by Ilmor unless they paid their bills. This left Lammers as a spectator atKyalami, after which the team folded.^[8]

Another Formula One option hit the rocks when Lammers was signed by theDAMSF3000 team for its debut season in1996, having already tested theirGD-01 car all through 1995. The project remained stillborn when DAMS fails to gather sufficient funding.^[5]

Fed up with driving inferior machines at the back of theFormula One grid, Lammers decides to switch tosportscar racing where he becomes a mainstay for the next three decades, both as a driver and a team owner.^[9] His time inGroup C includes seasons withRichard Lloyd Racing's privatePorsche 956, the worksJaguar team and the worksToyota team, while in the days ofLMP900 andLMP1, Lammers runs his ownRacing for Holland team with the JapaneseDome S101 chassis. His final call atLe Mans comes in2017 and2018 when he races theRacing Team NederlandDallara inLMP2, sharing withRubens Barrichello andJumbo Supermarkets CEO and team owner Frits van Eerd.^[10]

Having turned his back onFormula One, Lammers starts hisWorld Sportscar Championship career in1983 by joining top Porsche privateerRichard Lloyd Racing, taking several podium finishes withThierry Boutsen,Keke Rosberg andJonathan Palmer, while finishingsixth on his Le Mans debut. In1984, he is paired with Palmer, and the Canon-liveried956 takes victory over the works cars atBrands Hatch. The two add podiums atMonza, theNürburgring,Sandown Park andImola, and retire fromLe Mans in a winning position.

A mid-season switch sees Lammers snapped up byTom Walkinshaw atTWR Jaguar, and on his debut for the team at a very hotShah Alam in Malaysia he brings home the Jag in second place. Meanwhile, he makes hisIMSA GTP debut racing a March-Buick at Miami withRoberto Guerrero. In the1986 Daytona 24 Hours, driving the BF GoodrichPorsche 962, he is heading for victory when his brakes fail, leading to a sizeable crash that he escapes from. Later in the season, when his promising IndyCar adventure collapses with the disappointing Eagle, Walkinshaw is quick to lure Lammers back to TWR. The Dutchman is immediately competitive with second atSpa and third atJerez, before racing forNissan atWatkins Glen inIMSA GTP.

In1987, Lammers joins TWR Jaguar – now sponsored bySilk Cut – as a proper works driver, and is teamed with Grand Prix veteranJohn Watson. They win atJarama,Monza andFuji and take podiums atSilverstone,Brands Hatch andSpa. AtLe Mans, third driverWin Percy crashes their car out of the race. Team orders mean that they finish second in the championship.

1988 would become Lammers' most successful season in Group C racing. Now paired with ex-Lotus Formula One driverJohnny Dumfries, the two finish second atSpa and third atBrno, before being joined byAndy Wallace at theLe Mans 24 Hours. Lammers drives for 13 hours to be the anchor in a popular win for TWR Jaguar, the first for the marque since 1957. For this, he is congratulated byQueen Elizabeth II and rewarded with the title of Honorary Member of theBRDC. In IMSA, Lammers is part of the crew that wins theDaytona 24 Hours, after he is moved over from his retired car to joinMartin Brundle,Raul Boesel andJohn Nielsen in the lead Jaguar entry, winning the race. With regular teammateDavy Jones, Lammers wins atDel Mar and ends up on the podium atWest Palm Beach,Lime Rock,Mid-Ohio andSears Point.^[11]

In1989, the Jaguars were outclassed by the resurgentMercedes effort, with Lammers only managing to score a second place atJarama withPatrick Tambay. In the US, Lammers is more successful, winning inPortland andDel Mar, taking second in theDaytona 24 Hours,Lime Rock,Mid-Ohio andRoad America and third atSears Point andTopeka. The following year, Lammers wins theDaytona 24 Hours again, this time paired withAndy Wallace andDavy Jones, before taking third in theSebring 12 Hours. In theWSC, however, Jaguar's new turbo engine proves fast but unreliable, and together with Wallace, Lammers only picks up a pair of second places. Switching to the proven atmospheric V12 forLe Mans, Jaguar takes the double, but Lammers is in the second Jaguar across the line, having to recover from an earlier crash by teammateFranz Konrad.

Having opted for a switch toToyota, Lammers decides to wait in the wings for the new programme to come alive in 1992. In theWorld Championship, mated withGeoff Lees, Lammers takes two podium finishes, second atSuzuka and third atMagny-Cours. In theJapanese Sports-Prototype Championship, however, two wins atFuji andMine add up to another title for the Dutchman. One more Toyota appearance follows in 1993, finishing sixth for the Japanese constructor in theLe Mans 24 Hours.

In 1995, Lammers returns to IMSA to compete atDaytona andSebring in the Auto Toy StoreSpice-Chevrolet SE90. WithAndy Wallace, he wins the Sebring 12 Hours on the road but a timekeeping error declares the Fermín Velez/Andy Evans/Eric van de Poele Ferrari 333SP as the winner, while as a guest driver, Lammers joinsDerek Warwick andMario Andretti in aCourage-Porsche C36 to finish sixth in the1996 Le Mans 24 Hours.

In 1999 and 2000, Lammers returns to prototype racing, asKonrad Motorsport moves up to the LMP class with a Ford-enginedLola B98/10, followed by aB2K/10, while in the US he joins J&P Motorsports to race aPanoz LMP-1 Roadster-S. In the meantime, he progresses with setting up his own team for 2001. At Konrad, teaming up with countrymenTom Coronel andPeter Kox serves as a prequel to that.

Lammers embarks on a new era of sportscar success in 2001 when he rekindles his ties withJapanese manufacturer Dome to race their Judd-enginedS101, entering it in the newFIA Sportscar Championship and theLe Mans 24 Hours with young Dutch-born but Belgian-licensed Val Hillebrand as his teammate. For Le Mans, the Dutchman offers small segments of bodywork to small, private sponsors, giving the car the look of a driving chequered flag. A contribution of 2200 euros is enough to become aRacing for Holland sponsor. Lammers and Hillebrand dominate the final round ofthe championship before going into the new season as clear favourites, while placing themselves amongst the Audis atLe Mans. With three wins and five podiums Lammers and Hillebrand indeedtake the 2002 title in the leading SR1 class, beforedoubling up in 2003, again with three wins and five podiums. Meanwhile in 2002, Lammers races theCrawford SSC2K atDaytona and joinsChampion forSebring to take third in theirAudi R8.

When the FIA Sportscar Championship collapses after 2003, the Dome continues at Le Mans, where Lammers takesseventh in 2004 along withElton Julian and countryman John Bosch, the trio copying the result in2005. In the meantime, the Dutchman guests at Doran-Lista to take fourth in the2004 Daytona 24 Hours and withDyson Racing atSebring and thePetit Le Mans, finishing third in the latter. In the2005 Daytona 24 Hours, Lammers steps into theHoward-Boss MotorsportsCrawford DP03 to claim another US podium with third. Rejoining them for2006, their second cooperation gains no results.

With the start of theLe Mans Series in2005, Racing for Holland signs up for assorted rounds in 2005,2006 and2007, but by now the Dome is outclassed by the more recent LMP1 designs. After he shuts down the team while continuing to pay off its debts well into the next decade, Lammers returns as a gun for hire in 2008. In anLMP2 season dominated byJos Verstappen and the Van MerksteijnPorsche RS Spyder, Lammers teams up with the Swiss Horag-Lista team'sRS Spyder to finish the year fourth in class, along with teammateDidier Theys. AtLe Mans in 2008, he joins Greg Pickett andKlaus Graf in theCharouz Racing System Lola-Judd B07/17, but the car fails to finish.

Having gone into semi-retirement from 2010, Lammers hooks up withHope Racing to race the experimental SwissHyTech Hybrid-enginedORECA 01, and does one2016 Le Mans Cup round in the Racing Team HollandLigier-Nissan JSP3, but waits until 2017 for his final foray in top-level prototype racing, signing up for a three-year spell withRacing Team Nederland, the team funded by Dutch supermarket mogul Frits van Eerd. Racing theirDallara-Gibson P217 in the LMP2 class of theEuropean Le Mans Series, Lammers and Van Eerd claim a seventh and eighth as their best results in a full2017 ELMS season. In2018 and2019, Lammers acts as third driver to Van Eerd andGiedo van der Garde at Le Mans before closing the curtain on his active career.^[12]

On the back of the failed DAMS Formula One project, Lammers joins theLotus Racing outfit forBPR Global GT in1996. The GTI team is headed by countrymanToine Hezemans along with Ian Foley and George Howard-Chappell and runs a pair ofLotus Esprit V8s in theGT1 category. Teamed with Alex Portman,Perry McCarthy,Chris Goodwin,Andy Wallace,Fabien Giroix and Mike Hezemans, he claims pole at theNürburgring and takes second atSilverstone, but apart from that the car proves very unreliable. In1997, itsLotus Elise GT1 successor is outclassed byMcLaren-BMW andMercedes in the inauguralFIA GT Championship. After the Lotus takeover byProton, the GT1 programme is quickly canned.

In 1998, Lammers races the Bitter GT1 for Team Hezemans before switching to GT2 withRoock Racing andKonrad Motorsport, while helping to developNissan's newR390 GT1 car. AtLe Mans, he joinsErik Comas andAndrea Montermini to finish sixth, as the Nissans get beaten byPorsche's 911 GT1. Late in the season, Lammers returns to Konrad to share a911 GT2 with Franz Konrad in thePetit Le Mans, followed by a win atLaguna Seca.

Following a five-year GT break, the Dutchman teams up withProdrive to drive theirFerrari 550 Maranello in the2003 Petit Le Mans, finishing fourth in the GTS class, and then in 2008, having closed down his own team, Lammers makes a few guest appearances in GT racing, driving the Spa 24 Hours in theLamborghini Murciélago R-GT for the IPB-Spartak team. Meanwhile, he does a full season ofADAC GT sharingReiter Engineering'sLamborghini Gallardo GT3 with countryman Marius Ritskes, with three second places as his best results. Continuing in 2009 under the Racing Team Holland banner (not to be confused with Racing for Holland), the duo fails to score any more points. A one-off at Spa in the team's GT4Ford Mustang FR500C fails to materialise.

Another single GT4 appearance takes place in 2016 with aGinetta G55 GT4 drive in the Paul Ricard 24 Hours for Team Africa Le Mans. His final two GT races come at his farewell weekend atLe Mans in 2019, sharing aBentley Continental GT3 with Greg Mills for the same Team Africa Le Mans.^[13]

In1985, Lammers grabs the opportunity to make hisIndyCar debut, taking a drive with the small AMI Racing team. His strong performance in theirMarch-Cosworth 85C allows him to be snapped up by theForsythe-Green team, racing theirLola-Cosworth T800 andT900 in the final three races of the season, The Dutchman immediately scores points for them with fifth atLaguna Seca. At Miami, Lammers challengesDanny Sullivan for victory before making a mistake towards the end. This leads toDan Gurney'sAll-American Racers signing Lammers as their lead driver for the 1986 season, but that year's Eagle GC86 proves uncompetitive and Gurney withdraws the team ahead of the Indianapolis 500. Taking over theMachinists Union GC86 for three races later in the season leads to an eighth at Laguna Seca and ninth at Miami.^[5]

1986 is a season that proves Lammers' ultimate versatility, as he races in IndyCars, the WSC and Formula 3 while also taking up on an offer fromEddie Jordan Racing to replaceRussell Spence in the team's March-Cosworth 86B. His single appearance at the Le Mans-Bugatti circuit results in an 11th-place finish.

In 1991, while waiting for Toyota's new sportscar programme to come on song, Lammers is in Japan to helpDome with the development of the Mugen-engined F102, their new F3000 car. Rewarded with a one-off race outing at Suzuka, he takes third in his single appearance in theAll-Nippon F3000 Championship.

More F3000 follows in1993 after his Formula One deal with March fails to materialise. Accepting an offer to join the ItalianIl Barone Rampante team to follow in the footsteps ofRubens Barrichello, Lammers takes fourth at Enna as his best result before the team is forced to close shop before the end of the season.

Two years later, Lammers is back in F3000 as he joins the Vortex team owned by Dutch transport magnate Henny Vollenberg. He wins the F3000 South African GP at Kyalami, beatingKenny Bräck and teammateTarso Marques, and does three more European rounds before quitting the team when key staff decide to leave.^[5]

Making a surprise return toFormula 3, Lammers joins theMacau GP grid in 1985, racing a Ralt-Volkswagen RT30 forIntersport Racing. He embarrasses many of the regulars by qualifying and finishing third. In1986, he repeats the trick with Murray Taylor Racing's similar Ralt, again finishing third. Returning to Intersport in1987, Lammers goes one better to take second place in their Ralt-Toyota RT31, storming up from 11th on the grid, while his final Macau appearance comes in1988, again with Intersport. This time, he hauls his Ralt-Toyota RT32 up to sixth from 17th on the grid.^[5]

After his less successful 1993 season, Lammers makes a surprise move to join the touring car trail during theBTCC's burgeoningSuper Touring era. Teaming with his old friends fromTWR, he becomes teammate toRickard Rydell in a pair ofVolvo 850 SE cars. With its estate shape, the 850 SE is a crowd puller but it lacks ultimate pace and Lammers finishes no higher than fifth.^[5]

In 1980, during his time at ATS and Ensign, Lammers takes part in the second season of theBMW M1 Procar Series that is run on Grand Prix weekends, with several Grand Prix drivers such asJones,Lauda,Pironi andPiquet being part of the show. Lammers wins the opening race atDonington Park, finishes second atAvus and theNorisring, starts from pole position atMonaco and is the title favourite untilHans-Joachim Stuck drives him off the track atImola.^[5]

In his finalFormula One season, Lammers becomes a regular in the EuropeanRenault 5 Turbo Cup, representing Renault Netherlands and taking home one win. He continues in the series in 1983 to take four wins and the championship, and repeats the trick in even more dominant fashion in 1984, lifting eight victories on his way to the title.^[5]

In 2005 and 2006, theGrand Prix Masters are set up as a one-make motor racing series featuring retired Formula One drivers. Lammers takes part in the sole event of 2005, finishing ninth at Kyalami, and also races in both 2006 events, taking seventh at Losail and retiring from the race at Silverstone.^[14]

Having already retired as a full-time professional driver, Lammers guests in four races across three seasons (2010, 2011 and 2013) of the VW Scirocco R-Cup, with ninth in the 2013 Hockenheim round as his best result.^[14]

As further proof of his versatility, Lammers adds the DutchTulpenrallye to his portfolio in 1979, driving for the Opel Dealer Team.^[5] Over two decades later, he is invited to join Frits van Eerd's newDakar Rally enterprise in 2010. In the first of five Dakar outings in the Ginaf X2222 4x4 truck, Lammers fails to finish, before returning in the Ginaf works team in 2011, finishing 19th, and three more years with his own Ginaf-supported team, with 25th place in 2013 as his best result. In 2012, Lammers revives the chequeredRacing for Holland livery for a sponsorship concept similar to the one he explored in the previous decade.^[14]

Next to his career as a professional racing driver, Lammers has acted as the team principal of his own team on three very different occasions.

Between 1989 and 1991, Lammers runs his Opel Dealerteam Holland-supported Vitaal Racing outfit in Formula Opel Lotus. In his first year, he joins forces with Marlboro Challenge winnerPeter Kox, and together they win the EFDA Opel Lotus Euroseries as well as the Benelux series. In 1990, Lammers takes on another Marlboro Challenge winner, asMarcel Albers is promoted fromFormula Ford, resulting in sixth in the final European standings.^[5]

Setting upRacing for Holland at the start of the 21st century proves to be the birth of Lammers' final period of sportscar success at the highest level. With theirDome-Judd S101, Racing for Holland takes two consecutive titles in theFIA Sportscar Championship in 2002 and 2003 and continues with the Dome until 2007. Lammers later revives the Racing for Holland moniker – and a similar sponsorship scheme – for three of his Dakar outings in the following decade.

Not known as Racing for Holland as such, the team is the seatholder for the Netherlands in theA1 Grand Prix series that runs between 2005 and 2009. Lammers starts off withJos Verstappen as his driver, who takes victory at Durban in theopening 2005–06 season, whileJeroen Bleekemolen acts as the team's reserve driver. Bleekemolen steps up into the leading role for in2006–07, winning the Beijing street race, asRenger van der Zande takes his place as a backup driver, himself taking part in three races. Bleekemolen continues in 2007–08, now supported byArie Luyendyk Jr. Ditching its cheap Avon-shodLola-Zytek chassis for pukka Michelin-tyred Ferrari cars, the A1GP organisation hurry into bankruptcy in a final2008–09 season in whichRobert Doornbos andJeroen Bleekemolen take turns at the wheel, each winning a sprint race on their way to fourth for the Netherlands in the final standings.

After his decision to go into full retirement after the 2019 season, Lammers quickly assumes another duty, as he steps in to become sporting director of the organisation founded to revive theDutch GP atZandvoort. Starting in 2020, Lammers is more than just an ambassador for the event, and after a Covid-induced postponement in 2020, the Dutch dream is finally realised in 2021, when thefirst Dutch GP since 1985 is staged.^[15]

Lammers has two children from his marriage with Fardous Hashem.

Currently, Lammers is in a relationship since 2001 with Mariska Hoyinck. Together they have a son, René.

Lammers' youngest sonRené Lammers is currently competing in single seaters. The 16-year-old is a frontrunner in the2025 F4 Spanish Championship, having both won theKarting European Championship and finished runner-up in theKarting World Championship in the OK Category in 2023.
