In an unexpected turn of events, the motorsport world has learned that former McLaren team mate to Lewis Hamilton, Heikki Kovalainen, the Finnish racing driver of Formula 1 and SUPER GT fame, is to undergo open-heart surgery.
Kovalainen has been diagnosed with an ascending aortic aneurysm, a serious condition in which the artery leading from the heart bulges. Despite having no symptoms and being able to lead a normal day-to-day life, Kovalainen has decided to prioritise his health and undergo surgery, putting his rallying career on hold.

Kovalainen’s debut with McLaren was one of anticipation and excitement. After a rookie season with Renault in 2007 where he showed flashes of brilliance, Heikki was seen as a promising talent who could further McLaren’s Constructors’ Championship ambitions. 2008 looked to be a year of opportunity for the Finnish driver, with the machinery and support he needed to compete at the front of the grid.
Partnership with Hamilton
Having narrowly missed out on the World Championship in his debut season in 2007, Lewis Hamilton had already established himself as a formidable force within the team and the sport. The dynamic between Kovalainen and Hamilton was one of mutual respect. Known for his team-oriented approach, Kovalainen often found himself in a supporting role, contributing to the team’s strategy in a season dominated by intense competition with Ferrari.
Kovalainen’s time at McLaren was a mixed bag of memorable highs and challenging lows. One of the standout moments came at the 2008 Hungarian Grand Prix, where he took his first and only Formula One victory.
However, the 2008 season was also a challenging one for Kovalainen, as he struggled to match Hamilton’s pace and compete with the Ferrari duo of Felipe Massa and Kimi Raikkonen.

Life beyond F1
Kovalainen’s tenure at McLaren laid the foundations for his subsequent moves into F1 and other racing disciplines, including SUPER GT in Japan, where he enjoyed considerable success.
In retrospect, Heikki Kovalainen’s time as Lewis Hamilton’s McLaren teammate epitomises the Finnish driver’s enduring spirit and commitment to motorsport. While the partnership had its share of trials, it also celebrated the essence of Formula One racing – competition, collaboration and the relentless pursuit of excellence.
Current motorsport career
Kovalainen, who made a successful transition from circuit racing to rallying, was eagerly anticipating his return to the Japanese Rally Championship in 2024 with Rally Team AICELLO. The team, which switched from Skoda to a Toyota GR Yaris Rally2 this year, had high hopes for Kovalainen and co-driver Sae Kitagawa, with whom he won back-to-back titles in 2022 and 2023.
However, before the opening round of the championship, the Rally Mikana on 16 February, it was announced that Kovalainen would be retiring from competition. Katsuhiko Taguchi was announced as his replacement in the team line-up after a routine medical examination revealed the need for a more detailed examination of Kovalainen’s health.

Kovalainen: Open-heart surgery shock
After completing the necessary medical tests, it was confirmed that Kovalainen suffers from an Ascending Aortic Aneurysm. This condition, characterised by a weakness in the artery wall, carries a significant risk of tearing or rupturing, which can lead to severe, potentially fatal internal bleeding.
In a heartfelt statement, Kovalainen expressed his intention to undergo surgery in Finland, followed by a period of recovery, before making a hopeful return to rallying.
“I was diagnosed with ascending aortic aneurysm in a medical check-up recently and I was told not to be able to participate in rallies due to increased risk of aortic rupture,” he said. “I have no symptoms and I’m currently feeling good, and we are now making a plan on how to solve this issue.
“An open-heart surgery is our favourable solution at the moment and we are preparing for that. We hope to get an operation done and start the recovery as soon as possible.
“My aim is of course to return to the Japanese Rally Championship with Rally Team AICELLO. I was planning to participate in the rallies until the end of January, but after careful consideration with my team of doctors I’ve decided to try and fix this issue instead.
“I’m sorry for all our team partners and fans for this problem and many thanks for all the encouragement and support regarding this.”
