This weekend's Rally Sardinia marks the end of the line for Rally1 – and that's a great shame

For the last four years, the World Rally Championship's top-class has run to Rally1 regulations, featuring spaceframe machines powered by 1.6-litre turbocharged engines – initially with hybrid powertrains. Largely freed from the homologation rules of the World Rally Cars they replaced, Rally1 machines were just about the fastest thing to ever hit a rally stage.

But they were also hugely expensive and so, after just four years, the category is being ditched. This weekend's Rally Sardinia season finale will be the final outing for the Rally1 class, before the new WRC2027 machines – featuring less powerful engines and a spec tubular chassis – come into force. At Goodwood this year I had the chance to ride in a Toyota GR Yaris driven by 18-time WRC event winner Jari-Matti Latvala, for an up-close taste of the new machines.
