Frentzen was born to Heinrich-Harald Frentzen (1933–2012), a German entrepreneur and funeral director who raced between 1950 and 1957, and his Spanish wife Angela Lladosa (1937–2020). His father funded and supported his early racing career, also acting as team boss and head mechanic.
Frentzen began karting at the age of twelve and won the German Junior Kart Championship in 1981 at the age of fourteen. In 1983, he entered the CIK Asia Pacific Championships in Australia, and in 1984 finished runner-up in the 100cc class.
In 1985, Frentzen moved to car racing in the German Formula Ford 2000 series. After two seasons, he was runner-up in the 1987 series. He progressed to German Formula Opel Lotus in 1988 under the mentorship of former Formula One driver Jochen Mass, winning the German championship in his first year. His teammate Marco Werner finished third. Frentzen also participated in the Formula Opel Lotus Euroseries, finishing sixth with 56 points.
In 1989, Frentzen entered the German Formula 3 Championship alongside Michael Schumacher and Karl Wendlinger. A Formula One test drive was offered by the ONS (German National Motorsports committee) to the first driver to win a race. Schumacher secured this in a controversial race at Zeltweg, Austria — Frentzen claimed Schumacher had forced him off the track. Wendlinger won the championship; Frentzen and Schumacher finished joint runner-up on identical points totals.
In 1990, Frentzen entered International Formula 3000 with Eddie Jordan Racing, partnered by Eddie Irvine, finishing sixteenth with three points. That year he also drove a Mercedes-Benz C11 in the World Sports Prototype Championship, scoring one podium and six points. He continued in Formula 3000 in 1991 with Vortex Motorsport, scoring five points.
In 1994, Frentzen was given a Formula One drive by Peter Sauber in a Mercedes-powered car, alongside Karl Wendlinger. He qualified fifth on debut at the Brazilian Grand Prix and scored his first points with fifth at the Pacific Grand Prix. After Wendlinger sustained severe head injuries in a qualifying crash at Monaco, Frentzen became de facto team leader, having the measure of substitute team-mates Andrea de Cesaris and JJ Lehto. A notable result came at the European Grand Prix at Jerez, where he qualified fifth and ran third before a one-stop strategy dropped him to sixth. He finished thirteenth in the World Drivers' Championship.
For 1995, Sauber lost their Mercedes partnership — McLaren acquired the engines instead — and switched to Ford V8 power. Despite the less competitive engine, Frentzen delivered consistent performances, taking the team's first podium at the Italian Grand Prix and qualifying a season's-best fifth in Portugal. He finished ninth in the championship with 15 points, ahead of the returning Wendlinger and replacement Jean-Christophe Boullion.
In 1996, Johnny Herbert joined as team-mate and Ford upgraded to a V10 configuration, but the unit was less reliable than the previous V8. Frentzen was limited to three points-scoring finishes — in Monaco, Spain, and Japan — and finished twelfth in the championship with seven points. His move to Williams for 1997 was announced during the season.
For 1997, Frentzen replaced 1996 champion Damon Hill at Williams-Renault alongside Jacques Villeneuve. At the opening race, he led from the first corner until his pit stop, then retired late in the race when a brake disc exploded. He took his first victory at the fourth round, the San Marino Grand Prix, then claimed his first career pole position at Monaco but did not finish. After an inconsistent first half, Frentzen finished the second half with six points-scoring results including five consecutive podiums. He secured eight front-row starts and seven podiums overall, but was out-qualified by Villeneuve ten times out of fourteen. He finished third in the championship with 42 points to Villeneuve's 81, then was elevated to second following Michael Schumacher's disqualification from the standings.
For 1998, Renault ended factory engine support and Adrian Newey departed to McLaren. The team suffered a significant loss of form. Frentzen took a podium at Albert Park to open the season but could not repeat it, was again out-performed by Villeneuve, and finished seventh in the championship with 17 points. His departure was attributed to difficulty adjusting to the atmosphere at Williams and disagreements with technical director Patrick Head.
In 1999, Frentzen moved to Jordan in a straight swap with Ralf Schumacher, driving the Mugen-Honda powered car. He won twice — at the French Grand Prix and the Italian Grand Prix — and scored points in the majority of races. During the European Grand Prix he led after pole position, with both Mika Häkkinen and Eddie Irvine outside the points, but his car stopped on lap 32. He finished third in the World Drivers' Championship, 22 points behind champion Häkkinen, and was regarded by many as driver of the year.
In 2000, Honda also began supplying the BAR team, creating competition for engine priority. Frentzen managed two podiums — the team's best results — but Jordan finished behind BAR. In 2001, after injury, disagreements over technical direction, and a string of retirements, Jordan dismissed Frentzen mid-season and replaced him with Jean Alesi. Eight years later, Eddie Jordan revealed the dismissal was motivated by a desire to appease Honda and sign Takuma Sato. Frentzen took Alesi's seat at Prost, qualifying fourth at Spa before Prost collapsed financially at the end of the season.
Frentzen signed with Arrows on 30 December 2001 for the 2002 season, scoring points on two occasions and outpacing both Jaguar cars running the same engine. Arrows went bankrupt in August and released him. He made a one-off appearance for Sauber at the 2002 United States Grand Prix, replacing Felipe Massa, then rejoined Sauber full-time for 2003. He was evenly matched with highly rated team-mate Nick Heidfeld and scored a final Formula One podium at the penultimate race of the year, the United States Grand Prix, before retiring from the series.
For 2004, Frentzen moved to the Deutsche Tourenwagen Masters with Opel, encouraged by the success achieved there by Jean Alesi. His Opel Vectra was uncompetitive and he finished fourteenth in the standings. He remained with Opel for 2005, finishing eighth as the best-placed Opel driver, with a best result of third from pole at Brno in the Czech Republic. After Opel withdrew, Frentzen joined Audi for 2006, finishing third at the opening race at Hockenheim and again at Barcelona, ending the season seventh overall. He then quit, stating he had "no support from the team."
In April 2008, Frentzen drove in the Bahrain race of the Speedcar Series 2007/2008 season and later competed in the full 2008/2009 Speedcar Series season. He entered the 24 Hours of Le Mans twice — in 1992 and 2008. In 2008 he drove one of two factory Aston Martin DBR9s for Aston Martin Racing alongside Karl Wendlinger and Andrea Piccini in the GT1 class, finishing fourth in class and sixteenth overall.
Also in 2008, Frentzen built the HHF Hybrid Concept Car — based on a Gumpert Apollo chassis with a 3.3-litre V8 bi-turbo producing 520 hp and an electric motor of approximately 136 hp — and entered it in the 24 Hours Nürburgring. He finished the race but was not classified due to two gearbox failures.
In 2011, Frentzen won a special "ROC Legends" race at the Race of Champions against Hans-Joachim Stuck, Marc Duez, and Stig Blomqvist. He competed in the ADAC GT Masters in 2012 with a Callaway Competition Corvette Z06, and returned in 2014 with a HTP Motorsport Mercedes-Benz SLS AMG GT3.
In the early 1990s, Frentzen was in a relationship with Corinna Betsch, who later married Michael Schumacher. In 1999, Frentzen married Tanja Nigge. They have three children together. In 2020, Frentzen appeared on the 29th series of British motoring show Top Gear in a Germany versus Britain challenge.
