Behind the helmet
My name is Maximilian Boström and I am a racing driver from Stockholm. From my 2022 karting debut to the GT4 European Series — in just a few years.
Today I race the Toyota GR Supra GT4 for Toyota Gazoo Racing Sweden in the GT4 European Series — an international championship on some of Europe's most demanding circuits.
Last year I won Prince Carl Philip's Racing Trophy — and for 2026 I take the step from karting to full-fledged car racing in an ambitious push for the European GT4 championship. At the same time I took a place in GR Customer Racing's new international junior programme, the Young Driver Academy.
GR Customer Racing is Toyota's competition division, and the Young Driver Academy programme aims to identify the brand's future factory drivers through a series of evaluations and tests — both on track and at Toyota Racing's facilities in Cologne, Germany. The journey here has been unusually fast: I started karting as late as 2022 and early on emerged as one of Sweden's most promising talents. In 2025 — only three years after my karting debut — I won both the Rotax Max Challenge and the prestigious Prince Carl Philip's Racing Trophy.
”It feels fantastic to take this step into a whole new world. I am incredibly excited and grateful for this opportunity. My long-term goal is to one day fight for victory in the Le Mans 24 Hours, and this is the first small – but important – step on the way.”
