Audi has launched its third-generation Q7 SUV with a diesel engine capable of running on hydrotreated vegetable oil (HVO), a move that underscores the persistent tension between political ambition for synthetic fuels and the economic realities of the energy market.
Priced at £82,000, the vehicle represents a niche attempt to extend the life of internal combustion technology through alternative feedstocks rather than electrification.
The introduction of the HVO-compatible Q7 arrives as German political leaders, including Ursula von der Leyen and Friedrich Merz, continue to champion e-fuels as a viable pathway for decarbonizing transport.
However, the market response remains muted, with investors and consumers alike weighing the high upfront costs of such vehicles against the rapidly improving economics of battery-electric alternatives.
The Q7’s reliance on HVO highlights the infrastructure bottleneck: while the fuel is technically compatible with existing diesel engines, its availability remains limited and its cost significantly higher than conventional diesel.
This development reinforces the broader narrative that synthetic fuels are currently more of a political solution than a market-driven one.
